Items marked * represent the results of operations adjusted to reflect the
result before exceptional charges and other movements arising from
re-measurement. During the quarter there were no exceptional charges. For the
first quarter the re-measurement adjustments relate solely to the re-measurement
impact of IAS 39 on the results for the quarter. British Energy believes that
the results before re-measurement provide a better indication of the underlying
business performance.

-    EBITDA for the quarter was GBP121m* before re-measurement impact, GBP89m 
     after re-measurement impact.

-    Results reflect a return to profitability and the benefit of higher 
     electricity prices with an operating margin of GBP4.1/MWh at contracted
     summer prices.

-    Realised price was GBP24.7/MWh for the quarter up 37% compared to
     the first quarter 2004/05.

-    Operating cash inflow from operations was GBP59m for the quarter.
     Net debt decreased in the quarter by GBP54m to GBP166m.

-    Total output for the quarter was 17.4 TWh in line with plan (Nuclear 15.7 
     TWh, Coal 1.7 TWh) compared to 16.4 TWh (Nuclear 15.0 TWh, Coal 1.4 TWh) 
     in the first quarter of 2004/05.

-    Second quarter output as of 25 September 2005 was 14.8 TWh
     (Nuclear 14.0 TWh, Coal 0.8 TWh).

-    As at 25 September 2005, approximately 85% of planned output for the year 
     ending 31 March 2006 fixed at an average contracted price of GBP31.8/MWh.
     This includes the impact of capped price arrangements and higher prices for
     Eggborough taking advantage of the differential between peak and baseload
     prices.

-    Net additional losses from Heysham 1 and Hartlepool expected to
     increase by 0.5 TWh to around 1.5 TWh.

-    The Nuclear Liabilities Fund (NLF) Cash Sweep percentage was 64.80% at 3 
     July 2005, down from 64.99% at 31 March 2005 as a result of the exercise 
     of a number of the Company's warrants.

-    No accrual for any potential NLF Cash Sweep payment has been made in these 
     quarterly financial statements in line with the Group's accounting policy.

-    In accordance with the dividend policy set out within the accounts for the 
     period ended 31 March 2005, no dividend has been declared for the quarter.


Bill Coley, Chief Executive Officer said:

"The results reflect underlying improvement in our performance as a result of
the changes we are making. We remain tightly focused on improving the
operational reliability of our plant - and resolving the current issues at
Hartlepool and Heysham 1 is another step toward that objective. The Company's
improved profitability and positive cash contribution in the first quarter
reflects higher realised prices for summer power contracts and underlines our
confidence in British Energy's prospects."


Review and Outlook

Total output for the quarter was 17.4 TWh of which nuclear output was 15.7 TWh,
and output from Eggborough was 1.7 TWh. Second quarter output as of 25 September
2005 was 14.8 TWh of which nuclear output was 14.0 TWh in line with plan. During
the quarter, statutory outages were completed at Sizewell B and outages
commenced at Heysham 1 and Hunterston B. During the planned outages the Group
completed various plant improvements which were scheduled as part of the
Performance Improvement Programme (PiP). Unplanned losses for the quarter were
1.8 TWh leading to reduced Unplanned Capability Loss Factor (UCLF) at most
stations, partially offset by an overrun of the Sizewell B statutory outage.
Statutory outages at Heysham 1 and Hunterston B were completed during the second
quarter and the statutory outage at Dungeness B commenced. The statutory outage
of one unit at Dungeness B is progressing and the other unit at Dungeness B is
shut down for an unplanned outage and may require further work before their
return to service.

On 12 September 2005, the Company announced it had elected to maintain the
shutdown of two reactors at Hartlepool and to shutdown two reactors at Heysham 1
as a result of inspections to boiler closure units. The return to service of all
four units is dependent on the successful outcome of further inspections and a
programme of work at each unit. As a consequence, the return to service of the
four units is expected during mid to end October 2005. As a result, the net
additional unplanned losses are currently expected to increase by 0.5 TWh to
around 1.5 TWh. Whilst more challenging, the Company reconfirms it expects the
average annual nuclear output over the next two years to be 63 TWh.

Operating profit before depreciation and amortisation (EBITDA) for the quarter
was GBP121m before the IAS 39 re-measurement impact reflecting the benefit of
increased electricity prices. Operating costs were in line with plan and reflect
increased revenue spend associated with investment in plant during 2005/06. As
at 3 July 2005 the Group had cash and cash equivalents and restricted cash
balances amounting to GBP510m, of which GBP250m was deposited as collateral in
support of trading and operating activities.

Forward market prices for electricity for winter 2005/06 delivery have increased
during the quarter, however they continue to show considerable volatility. As at
25 September 2005, the Company had fixed price contracts in place for
approximately 85% of planned output for the financial year 2005/06 at an average
contract price of approximately GBP31.8/MWh. This price includes the impact of
capped price arrangements of approximately 5 TWh at around GBP30/MWh and the
benefit of higher prices achieved as a result of Eggborough taking advantage of
the differential between peak and baseload prices. This price excludes Balancing
Services Use of System and other electricity market participation charges of
around GBP0.7/MWh, market costs incurred through output variation and
unreliability expected to be around GBP1.0/MWh. The level of output at fixed
prices has been impacted by unplanned losses at Heysham 1 and Hartlepool and the
requirement to manage collateral. The Company intends to progressively close out
its exposure to market prices for the financial year 2005/06 subject to limits
on trading collateral which are easing and has made satisfactory progress in
fixing prices for the financial year 2006/07.

On 15 September 2005, the Group announced the completion of the necessary
technical and economic evaluation regarding the potential accounting life
extension at Dungeness B. This has resulted in the accounting life of Dungeness
B being extended by ten years to 2018, five years beyond the accounting life
extension assumed as part of the fair value exercise related to the
restructuring on 14 January 2005.

During the quarter, investment expenditure across the whole Group on plant
projects, major repairs and strategic spares, including costs associated with
PiP, totalled GBP41m, of which GBP18m has been capitalised. In addition, GBP24m 
of overhaul costs were capitalised in the quarter. Based on its current
expectations of future electricity prices and output, and therefore financial
resources, the Company reconfirms that investment in plant projects, major
repairs and strategic spares including costs associated with PiP across the
whole Group is expected to be in the range of GBP230m to GBP250m for the year 
ending 31 March 2006.

On 21 September 2005, the Department for Environment Food and Rural Affairs
issued an update regarding the implementation of the Large Combustion Plant
Directive ("LCPD"). The update indicated that the Government will apply emission
limit values to control emissions from power stations in the UK from January
2008. The update gave no further clarification as to whether Eggborough would be
treated as having separate plants for the purposes of LCPD. If the final
decision is to consider the four units at Eggborough as a single plant for LCPD
purposes then there could be a requirement to materially restrict the operations
of the two non-FGD units from 2008 in order to comply with the proposed emission
limit values.


Explanatory notes

These results for British Energy have been prepared under International
Financial Reporting Standards (IFRS) for the quarter ended 3 July 2005. This is
the first set of quarterly results prepared under IFRS. As part of the
transition from United Kingdom Generally Accepted Accounting Principles (UK
GAAP) to IFRS, a Restatement of Results for Transition to International
Financial Reporting Standards was published on 21 September 2005.

Electricity demand in the UK is seasonal, in that demand and prices are
generally lower in summer than in winter. As a result, British Energy (and other
generators) schedule a significant proportion of planned outages for the summer
months. This seasonality in both prices and output has a direct effect on
financial performance and cash flows.


A summary of the results is set out below:

Notes:

 1. EBITDA is defined by the Company as operating profit before interest, income
    taxes, depreciation and amortisation and has been presented both including
    and excluding the effects of re-measurement. The Company has included
    information concerning EBITDA because it believes that it is used by certain
    investors as one measure of the Company's financial performance. EBITDA is
    not a measure of financial performance under IFRS and is not necessarily
    comparable to similarly titled measures used by other companies. EBITDA
    should not be construed as an alternative to operating income or to cash
    flows from operating activities (as determined in accordance with IFRS) as a
    measure of liquidity.

                            British Energy Group plc

                   Results for the Quarter Ended 3 July 2005


Management's Discussion and Analysis - Financial Condition and Results Of
Operations


Overview and Outlook

In the following  discussion  the  'quarter'  refers to the quarter ended 3 July
2005 unless otherwise stated. In this discussion  references to 'British Energy'
or the 'Company' are to British Energy Group plc.  References to the 'Group' are
to the  Company  and its  subsidiaries.  The  results  of  operations  have been
adjusted to reflect the result before  exceptional  charges and other  movements
arising from  re-measurement  for the impact of IAS 39  'Financial  Instruments:
Recognition and Measurement' (IAS 39) for the quarter.  During the quarter there
were no exceptional charges.  British Energy believes that the adjusted measures
provide a better indication of the underlying business performance.

The Group was successfully  restructured on 14 January 2005 and continues to own
and operate eight nuclear power stations and one coal-fired power station in the
UK.  The  Company's  three   imperatives  are  achieving   world-class   nuclear
operational  performance;  improving its financial stability;  and pursuing life
extensions for its stations.

To achieve these goals the Group is investing in activities  required to improve
output and reliability of its nuclear power stations while managing energy price
risk through its electricity  trading division.  To support this,  investment in
plant projects,  major repairs and strategic  spares  including costs associated
with the Performance  Improvement Programme (PiP) for the quarter was GBP41m and
the Company  confirms that  investment is expected to be in the range of GBP230m
to GBP250m for the financial year 2005/06. Safety and environmental  performance
also continue to be a fundamental priority of the Company.

Total output for the quarter was 17.4 TWh of which nuclear  output was 15.7 TWh,
in line with plan, and output from Eggborough was 1.7 TWh. Second quarter output
as of 25  September  2005 was 14.8 TWh of which  nuclear  output was 14.0 TWh in
line with the Company's  expectation  to generate  nuclear  output of 63 TWh per
annum on average over the current and next financial  year.  During the quarter,
statutory  outages were completed at Sizewell B and outages commenced at Heysham
1 and Hunterston B. During the planned outages the Group completed various plant
improvements  which  were  scheduled  as part of PiP.  Unplanned  losses for the
quarter were 1.8 TWh leading to reduced Unplanned  Capability Loss Factor (UCLF)
at most  stations,  partially  offset by an overrun of the  Sizewell B statutory
outage.  Statutory  outages at Heysham 1 and Hunterston B were completed  during
the second quarter and the statutory outage at Dungeness B commenced.

Operating profit before  depreciation and amortisation  (EBITDA) for the quarter
was GBP121m before the IAS 39  re-measurement  impact  reflecting the benefit of
increased electricity prices. Operating costs were in line with plan and reflect
increased  revenue spend associated with investment in plant during 2005/ 06. As
at 3 July 2005 the  Group  had cash and cash  equivalents  and  restricted  cash
balances  amounting to GBP510m,  of which GBP250m was deposited as collateral in
support of trading and operating activities.

Forward market prices for electricity for winter 2005/06 delivery have increased
during the quarter, however they continue to show considerable volatility. As at
25  September  2005,  the  Company  had  fixed  price  contracts  in  place  for
approximately 85% of planned output for the financial year 2005/06 at an average
contract price of approximately  GBP31.8/MWh.  This price includes the impact of
capped price  arrangements of  approximately  5 TWh at around  GBP30/MWh and the
benefit of higher prices achieved as a result of Eggborough  taking advantage of
the differential  between peak and baseload prices. The level of output at fixed
prices has been impacted by unplanned losses at Heysham 1 and Hartlepool and the
requirement to manage collateral. The Company intends to progressively close out
its exposure to market prices for the financial  year 2005/06  subject to limits
on trading  collateral  which are easing and has made  satisfactory  progress in
fixing prices for the financial year 2006/07.

In  accordance  with the  dividend  policy set out within the  accounts  for the
period ended 31 March 2005 and in the Dividend Policy section below, no dividend
has been declared for the quarter.

On 15 September  2005,  the Group  announced  the  completion  of the  necessary
technical and economic  evaluation  regarding the  potential  life  extension at
Dungeness  B. This has  resulted  in the  accounting  life of  Dungeness B being
extended by ten years to 2018,  five years beyond the extension  assumed as part
of the restructuring related fair value exercise.


Key Points on Results

-    EBITDA for the quarter was GBP121m* before re-measurement impact,
     GBP89m after re-measurement impact.

-    Operating profit was GBP77m* in the quarter before re-measurement impact, 
     GBP45m after re-measurement impact.

-    Profit before tax of GBP64m* was recorded in the quarter before
     re-measurement impact, GBP32m after re-measurement impact.

-    Total output for the quarter was 17.4 TWh.  Nuclear output in the quarter 
     (94 days) was up by 5% to 15.7 TWh, compared with 15.0 TWh in the 2004/05 
     first quarter (91 days).  Coal output was 1.7 TWh in the quarter compared 
     to 1.4 TWh in the first quarter of 2004/05.

-    Realised price (which is calculated by dividing revenue, before any 
     re-measurement impact, energy supply costs recharged to customers and
     miscellaneous income, and is net of energy purchase costs, by total output
     during the period) was GBP24.7/MWh for the quarter.

-    Total operating unit costs, excluding revalorisation (which are calculated 
     by dividing the total operating costs, before any re-measurement, energy 
     supply costs recharged to customers and energy purchases, by total output
     during the period), were GBP20.6/MWh for the quarter.

-    Operating cash inflow from operations was GBP59m for the quarter. Net debt 
     decreased in the quarter by GBP54m to GBP166m.

-    The Nuclear Liabilities Fund (NLF) Cash Sweep percentage was 64.80% at 3 
     July 2005, down from 64.99% at 31 March 2005 as a result of the exercise of
     a number of the Company's warrants.  No accrual for any potential NLF Cash 
     Sweep payment has been made in these quarterly financial statements. In
     accordance with the Government Contribution Agreement, an accrual will be 
     made for the weighted average NLF Cash Sweep percentage payment applied to 
     adjusted net cash flow as at 31 March 2006 to the extent adjusted net cash 
     flow arising from operations during the year is above GBP290m plus posted 
     collateral (subject to a GBP200m minimum) at 31 March 2006.

Items  marked *  represent  the  results of  operations  adjusted to reflect the
result   before   exceptional   charges  and  other   movements   arising   from
re-measurement.  During the quarter there were no exceptional  charges.  For the
first quarter the re-measurement adjustments relate solely to the re-measurement
impact of IAS 39 on the results for the quarter.  British  Energy  believes that
the adjusted  measures  provide a better  indication of the underlying  business
performance.


Explanatory Notes

This report  contains  British  Energy's  results  prepared under  International
Financial  Reporting Standards (IFRS) for the quarter ended 3 July 2005. This is
the  first  set of  quarterly  results  prepared  under  IFRS.  As  part  of the
transition  from United Kingdom  Generally  Accepted  Accounting  Principles (UK
GAAP) to IFRS a Restatement of Results for Transition to International Financial
Reporting  Standards  was  published  on 21  September  2005.  The main areas of
difference between UK GAAP and IFRS for British Energy are:
     
-    goodwill
-    pensions
-    deferred tax
-    financial instruments

This is the first time since completion of the  restructuring of the Group on 14
January 2005 that British  Energy has published  results for its first  quarter.
Therefore  this  report does not contain  any  comparative  quarterly  financial
information  but,  where  appropriate,   does  contain   comparative   quarterly
non-financial information.

From 1 April 2005,  the Company has  operated a 4:4:5 week  reporting  cycle for
quarterly  reporting,  with reporting  periods ending on a Sunday.  Accordingly,
this set of  quarterly  results  has been  prepared  to 3 July 2005.  The annual
results will be prepared to 31 March 2006.

Electricity  demand  in the UK is  seasonal,  in  that  demand  and  prices  are
generally lower in summer than in winter. As a result, British Energy (and other
generators) schedule a significant  proportion of planned outages for the summer
months.  This  seasonality  in both  prices and  output  has a direct  effect on
financial performance and cash flows.

Certain statements in this document are 'forward-looking'  statements as defined
in Section 21E of the US Securities  Exchange Act of 1934. Such  forward-looking
statements include, among others:

-    the anticipated development of the UK electricity industry, the future 
     development of regulation of the UK electricity industry, the effect of
     these developments on our business, financial condition or results of 
     operation; and

-    other matters that are not historical facts concerning the Group's business
     operations, financial condition and results of operations.

These forward-looking  statements involve known and unknown risks, uncertainties
and other  factors  which are in some cases  beyond the Group's  control and may
cause its  actual  results  or  performance  to  differ  materially  from  those
expressed   or  implied  by  such   forward-looking   statements.   Due  to  the
uncertainties and risks associated with these forward-looking statements,  which
apply only as at the date  hereof,  the Company is  claiming  the benefit of the
safe harbour  provision  contained in Section 21E of the US Securities  Exchange
Act of 1934.

EBITDA is defined by the Company as operating  profit  before  interest,  income
taxes,  depreciation  and amortisation and has been presented both including and
excluding the effects of  re-measurement.  The Company has included  information
concerning  EBITDA  because it believes that it is used by certain  investors as
one measure of the Company's financial  performance.  EBITDA is not a measure of
financial performance under IFRS and is not necessarily  comparable to similarly
titled  measures used by other  companies.  EBITDA should not be construed as an
alternative to operating  income or to cash flows from operating  activities (as
determined in accordance with IFRS) as a measure of liquidity.

British Energy has also prepared a quarterly  report on a Form 6-K under US GAAP
for the quarter ended 3 July 2005. The full financial  statements prepared under
UK GAAP for the  period  ended  31 March  2005  and the  notes  thereto  are not
included  in this  report  but  are  available  on the  British  Energy  website
(www.british-energy.com).

The following  discussion and analysis  should be read in  conjunction  with the
unaudited  financial  statements for the quarter ended 3 July 2005 and the notes
thereto which are included in this report.


OPERATIONAL REVIEW


Plant Output

Nuclear  output was 15.7 TWh (a 73% load factor) for the quarter (94 days).  The
nuclear  output for the quarter ended 30 June 2004 (91 days) was 15.0 TWh (a 72%
load factor).  During the period a statutory outage was completed at Sizewell B,
and one  started  at each of  Heysham 1 and  Hunterston  B.  Since  successfully
completing its statutory outage,  following an overrun,  Sizewell B has operated
continuously at full power.  There were planned outages  amounting to 3.8 TWh of
lost  output.  Unplanned  losses for the quarter were 1.8 TWh leading to reduced
UCLF at most stations, offset by the Sizewell B statutory outage overrun.

Output from the  coal-fired  power station at Eggborough  was 1.7 TWh during the
quarter.  For the  quarter  ended 30 June  2004,  the  output  was 1.4  TWh.  As
Eggborough is operated primarily as a flexible mid-merit plant, its output level
is influenced by market prices,  the Company's  contracted  trading position and
the extent to which it is operated as cover for unplanned outages at the nuclear
power stations.


Performance Improvements

Work  continues to implement PiP with the aim to improve the  reliability of the
nuclear power stations and reduce the level of unplanned  nuclear  losses.  Last
year the focus was on improvements  relating to people,  plant and processes and
is now on  implementation,  with an  emphasis  on  integrating  PiP  across  the
business.

Considerable  progress has been made during the quarter in putting the processes
and support in place.  Managers are carrying  out task  observations  across all
sites to allow  the  identification  and  removal  of  obstacles  from the daily
activities of staff that affect safety and reliability.

Non-outage  defect  backlog  has  reduced  by 11% in the  quarter as a result of
focusing on equipment  reliability,  work management and an improved operational
focus.  Both nuclear  reportable  events and  unplanned  trips show an improving
trend in the quarter.

Independent  of  internal  improvement  monitoring  arrangements,  a  number  of
favourable WANO  assessments  have been received  recently with positive reports
received from recent reviews at Sizewell B, Hinkley Point and Heysham 1 and 2.


Investment Expenditure

During the  quarter,  investment  expenditure  across  the whole  Group on plant
projects,  major repairs and strategic  spares,  including costs associated with
PiP, totalled GBP41m, of which GBP18m has been capitalised.  In addition, GBP24m
of overhaul costs were capitalised in the quarter.  The main investment in plant
in the period  included  additional  safety  work at  Hartlepool  and Heysham 1,
turbine work at Heysham 1, low  pressure  rotor  refurbishment  at Heysham 2 and
Hunterston and generator transformer  refurbishment at Hartlepool.  Based on its
current  expectations  of future  electricity  prices and output,  and therefore
financial  resources,  the Company reconfirms that investment in plant projects,
major repairs and strategic  spares  including costs  associated with PiP across
the whole  Group is  expected  to be in the range of GBP230m to GBP250m  for the
year ending 31 March 2006.


Safety and Environmental Performance

A key priority of the Group is to manage the safety of our plant, people and the
general  public.  Lost time  accidents  for staff and non-staff  have  increased
during the quarter  largely due to an increased  number of  accidents  involving
non-staff.  We remain absolutely  committed to safety and ensuring the safety of
our staff, non-staff and the general public.

The  environmental   performance  of  the  Group  also  continues  to  remain  a
fundamental priority of the Company.  Environmental  performance indicators have
been  reclassified and as a result we have no comparable data but the indicators
in the year to date are ahead of the Group's expectations.


Operational Update

On 12  September  2005,  the Company  announced  it had elected to maintain  the
shutdown of two reactors at Hartlepool and to shutdown two reactors at Heysham 1
as a result of inspections to boiler closure units. The return to service of all
four units is dependent on the successful  outcome of further  inspections and a
programme of work at each unit. As a  consequence,  the return to service of the
four units is expected  during mid to end  October  2005.  As a result,  the net
additional  unplanned  losses are  currently  expected to increase by 0.5 TWh to
around 1.5 TWh. Whilst more challenging,  the Company  reconfirms it expects the
average annual nuclear output over the next two years to be 63 TWh.

Flue Gas Desulphurisation (FGD) installation on Units 3 and 4 at Eggborough has
been completed and the plant was taken over from the contractors on 1 September
2005.

Inspections  carried out during the Unit 4 outage at  Eggborough  in the quarter
revealed  evidence of cracking on a number of the turbine  blades.  The affected
turbine blades will be removed and this unit is expected to return to service as
planned,  albeit with a small reduction in capacity.  Inspections of other units
showed that cracking was not widespread.

On 21 September  2005,  the Department  for  Environment  Food and Rural Affairs
issued an update  regarding the  implementation  of the Large  Combustion  Plant
Directive (LCPD) pending a formal decision by the Government expected before the
end of this year. The update  indicated that the Government  will apply emission
limit  values to control  emissions  of  sulphur  dioxide,  nitrogen  oxides and
particulates  from  power  stations  in the UK from  January  2008.  The  update
repeated the European  Commission's  view that existing plants whose waste gases
are discharged through a common stack should be considered as a single plant for
the purposes of the LCPD,  however it gave no further  clarification  of whether
multiple  generating  units each with their own separate flue (as at Eggborough)
can be treated as separate  plants for the purposes of the LCPD pending  further
discussions with the European Commission.

If the final  decision is to consider the four units at  Eggborough  as a single
plant for LCPD purposes then there could be a requirement to materially restrict
the  operations  of the two non-FGD  units from 2008 in order to comply with the
proposed emission limit values.


NDA Strategy

The Nuclear Decommissioning  Authority published its draft strategy document and
has  provided  an  opportunity  for full and open  consultation  on the issue of
decommissioning the UK's nuclear waste legacy. As major stakeholders,  we intend
to play a full part in this consultation.

The Company has contracts with Springfields  Fuels Limited (a subsidiary of BNFL
plc) for the supply of AGR fuel and with British  Nuclear Group (a subsidiary of
BNFL plc) for the receipt of all the spent fuel from the  Group's AGR  stations.
These contracts are for the full lifetime of the Group's AGR stations.


Quinquennial Review

The quinquennial  review of our nuclear  liabilities is underway and the results
of this review will be finalised  towards the end of 2005. The review may result
in a significant  change in value of the nuclear  liabilities  due to changes in
strategy and cost estimates but as a result of the arrangements with the NLF and
Government,  any change in value of the nuclear liabilities will be offset by an
equal and opposite change in the value of the NLF receivable.


TRADING REVIEW


Trading Position

Forward market prices for electricity for winter 2005/06 delivery have increased
during the quarter, however they continue to show considerable volatility. As at
25  September  2005,  the  Company  had  fixed  price  contracts  in  place  for
approximately 85% of planned output for the financial year 2005/06 at an average
contract price of approximately  GBP31.8/MWh.  This price includes the impact of
capped price  arrangements of  approximately  5 TWh at around  GBP30/MWh and the
benefit of higher prices achieved as a result of Eggborough  taking advantage of
the differential between peak and baseload prices. This price excludes Balancing
Services Use of System and other  electricity  market  participation  charges of
around  GBP0.7/MWh  and market  costs  incurred  through  output  variation  and
unreliability  expected  to be around  GBP1.0/MWh.  The level of output at fixed
prices has been impacted by unplanned losses at Heysham 1 and Hartlepool and the
requirement to manage collateral. The Company intends to progressively close out
its exposure to market prices for the financial  year 2005/06  subject to limits
on trading  collateral  which are easing and has made  satisfactory  progress in
fixing prices for the financial year 2006/07.

Realised   price  (which  is   calculated  by  dividing   revenue,   before  any
re-measurement   impact,   energy  supply  costs   recharged  to  customers  and
miscellaneous  income,  and is net of energy  purchase  costs,  by total  output
during the period) was GBP24.7/MWh for the quarter.


Collateral

The  Group's  strategy  for  securing  part of its income  through  fixed  price
contracts  means that in a volatile  and rising  electricity  market  collateral
requirements are also volatile and rising.  The Group's ability to secure longer
term certainty on its income is limited by the amount of collateral and headroom
available to cover collateral  volatility.  The Group mitigates a certain amount
of this  risk by  selling  electricity  through  a number  of  routes  to market
including through its direct supply business (to large industrial and commercial
customers) which does not require as much collateral and also through the use of
financial  products which provide  electricity price protection but require less
collateral.

Total operating unit costs were GBP20.6/MWh for the quarter.

The component elements of the operating costs are discussed below.


Fuel Costs

Total fuel costs amounted to GBP137m for the quarter.  Nuclear fuel costs were
GBP84m for the quarter and Eggborough fuel costs for the quarter were GBP53m.
Eggborough fuel costs included GBP24m attributable to carbon costs.

The market price of CO2 allowances has risen since the beginning of 2005 and was
approximately EUR25/tonne at 3 July 2005, increasing the marginal cost of coal 
and gas generation.


Energy Purchases

Energy purchases of GBP4m primarily represent the cost of contracts entered into
in order to obtain Renewable Obligation Certificates (ROCs) and Levy Exemption
Certificates (LECs).


Materials and Services

Materials and services costs comprise the operating expenses of the power
stations and support functions excluding fuel costs, staff costs and
depreciation.  The costs during the quarter were GBP100m.


Staff Costs

Staff costs were GBP80m for the quarter and included pension costs of GBP14m.

Employer contributions to the pension scheme were GBP17m for the quarter
reflecting the impact of new salary sacrifice arrangements introduced from 1
April 2005.


Depreciation

Depreciation charges were GBP43m for the quarter.


Amortisation

Amortisation charges on capitalised software costs were GBP1m for the quarter.


Other Operating Income

The other operating income of GBP3m for the quarter relates to utilisation,
excluding revalorisation, of the net commodity contracts provision, which was
established on restructuring.


Energy Supply Costs

Energy supply costs mainly comprise the costs incurred for the use of the
distribution and transmission systems and accrued costs of ROCs under the
Renewable Obligation and are fully recovered through revenue.  Total energy
supply costs were GBP82m for the quarter.


NLF Cash Sweep Payment

In accordance with the Group's accounting policy these quarterly financial
statements make no accrual for any potential future NLF Cash Sweep payment that
may be payable based on the full year results.


Operating Profit

The Group operating profit for business performance was GBP77m for the quarter.


Financing Charges

The total financing charges are analysed below:

Revalorisation of nuclear liabilities arises because nuclear liabilities are
stated in the balance sheet at current price levels, discounted at 3% per annum
real from the eventual payment dates.  The revalorisation charge is the
adjustment that results from restating these liabilities to take into account
the effect of inflation in the period and to remove the effect of the discount
for the quarter.

A revalorisation credit arises in respect of movements in the value of nuclear
liabilities receivable and the NLF receivable to take account of the underlying
movement in nuclear liabilities.

Revalorisation charges arise in respect of the fixed decommissioning obligation
and the contracts provision to reflect the unwinding of the discount for the
quarter.


IAS 39 and Contract Provisions

The total movements on the IAS 39 values and the net commodity contracts
provision established as part of the fair value exercise are analysed below:




                                                                                                 Contract

Following the adoption of IAS 39 at 1 April 2005 the opening value of GBP34m has
risen by GBP84m to GBP118m.  The effect on operating profit in the quarter has
been a reduction of GBP32m with the balance of GBP52m being recognised through 
the statement of recognised income and expense.

The contract provision relates to contracts outwith the scope of IAS 39, which
were initially valued at the restructuring effective date of 14 January 2005.
The provision is being utilised over the lives of these contracts.  The
provision has increased by GBP1m in the quarter.


Taxation

Income tax is calculated on the profit for the period, before taking account of
the income statement effect of any adjustments to the measurement and
classification of financial instruments required by IAS 39, at the anticipated
annual effective rate applicable to this profit.  Any charge for the NLF Cash
Sweep payment included in the annual results will not be tax deductible and
therefore the anticipated annual effective rate is significantly more than the
standard rate of 30%.  Adjustments to profit arising from the application of
measurement and classification rules for financial instruments contained in IAS
39 are tax effected at the standard rate of 30%.  There is no current tax charge
in the period due to the availability of trading losses carried forward.  The
charge of GBP26m before re-measurement and GBP16m after re-measurement in the 
period consists of deferred tax only.


Profit after Tax

As a result of the factors discussed above, the net profit for the period
attributable to equity shareholders was GBP38m before re-measurement and GBP16m
after re-measurement.


Earnings per Share

There was an earnings per share of 6.7p for the quarter, based on the net profit
for the period before the effect of re-measurement divided by the weighted
average number of ordinary shares in issue during the period.  After the effect
of re-measurement, earnings per share was 2.8p for the quarter.

The diluted earnings per share for the quarter was 6.6p before the effect of
re-measurement and 2.8p after the effect of re-measurement.  The conversion
rights of the NLF Cash Sweep is not considered dilutive.


Actuarial Loss on Pensions

There has been one significant change in the actuarial  assumptions adopted at 3
July 2005 compared with 31 March 2005 that mainly  contributed  to the actuarial
loss on  pensions  of  GBP172m  that  has  been  recorded  in the  statement  of
recognised  income and expense.  The discount rate used to value the liabilities
has changed from 5.5% per annum to 5.0% per annum in line with market changes in
the yield on  long-dated  corporate  bonds  over the  period.  The effect of the
change  in the  discount  rate  is to  place  a  higher  value  on  the  pension
liabilities, resulting in a significant actuarial loss in the quarter.


Research and Development

The Group supports primarily scientific and engineering research activities
directed toward securing further improvements in the reliability, performance
and safety of the generating business and related activities.  For the quarter
expenditure on research and development was GBP3m which is included within
material and services costs.


Future Reporting

At the Company's recent Annual General Meeting a resolution was passed that
amended the Company's Articles of Association.  These changes allow the Group to
deregister from the US Securities and Exchange Commission subject to receiving
consent from the holders of the Group's bonds to the cessation of reporting
under US GAAP.

The next set of quarterly results to be presented will be for the quarter ending
2 October 2005.


LIQUIDITY AND CAPITAL RESOURCES


Cash Flow from Operating Activities

A reconciliation of profit after tax to earnings before interest, income taxes,
depreciation and amortisation (EBITDA) is shown in the following table.  EBITDA
is a measure commonly reported and widely used by analysts, certain investors
and other interested parties, as well as a measure used internally by the Group.
The EBITDA is further reconciled to the operating cash inflow and movement in
restricted cash and then to the increase in total cash.

The operating cash inflow and movement in restricted cash for the quarter was
GBP93m.  When adjusted for capital expenditure, net interest paid and the 
exercise of warrants there was an increase in total cash of GBP54m for the 
quarter.  The adverse movement on working capital of GBP26m for the quarter can
be attributed mainly to a reduction in trade and other payables.


Management of Restricted Cash

The balances on the term deposit accounts holding the collateral amounts
increased by GBP34m from GBP216m at 31 March 2005 to GBP250m at 3 July 2005.  
Also included in restricted cash at 31 March 2005 and 3 July 2005 was GBP5m.


Capital Resources

At 3 July 2005, total debt of GBP676m comprised:

-    The Amended Credit Agreement, a long-term project finance loan, of GBP145m 
     secured on the assets of Eggborough Power Limited (EPL), a subsidiary
     company that operates the Eggborough coal-fired power station.  The loan 
     bears interest at a rate of 7.0%.

-    An aggregate principal amount of GBP531m Sterling denominated guaranteed 
     bonds due between 2005 and 2022 (the Bonds).  The Bonds have a coupon
     of 7.0%.

The long-term project finance loan is secured by a mortgage of shares in EPL, an
assignment of the EPL Share Purchase Agreement and Tax Deed of Covenant and a
debenture comprising fixed and floating charges over EPL assets.

Net debt decreased in the quarter by GBP54m to GBP166m.


Liquidity

At 3 July 2005 the Group had cash and cash equivalents and restricted cash,
including amounts posted as collateral, amounting to GBP510m, of which GBP250m 
was deposited as collateral in support of trading activities.

The Group's main source of liquidity is its operating businesses.  Cash
generation by the operating businesses is dependent upon the reliability of the
Group's power stations in producing electricity, the realised selling price for
electricity, operational risk and investment expenditure and maintenance
requirements.

The lack of an investment grade credit rating has meant that the Group continues
to provide significant levels of collateral to counterparties in order to cover
their trading exposures and maintain trading arrangements, thereby substantially
reducing the levels of cash resources available to the Group.

The Group's future liquidity may also be impacted by the additional employer
pension contributions set out within the 'Financial Review' section of our
report and accounts for the period ended 31 March 2005.  Our exposures to market
risk have not changed materially since 31 March 2005.


Post Balance Sheet Events

On 15 September 2005, the Group announced the completion of the necessary
technical and economic evaluation regarding the potential life extension at
Dungeness B.  This has resulted in the accounting life of Dungeness B being
extended by ten years to 2018, five years beyond the extension assumed as part
of the restructuring related fair value exercise.

On 12 September 2005, the Company announced it had elected to maintain the
shutdown of two reactors at Hartlepool and to shutdown two reactors at Heysham 1
as a result of inspections to boiler closure units.  The return to service of
all four units is dependent on the successful outcome of further inspections and
a programme of work at each unit.  As a consequence, the return to service of
the four units is expected during mid to end October 2005.  As a result, the net
additional unplanned losses are currently expected to increase by 0.5 TWh to
around 1.5 TWh.  Whilst more challenging, the Company reconfirms it expects the
average annual nuclear output over the next two years to be 63 TWh.

On 21 September 2005, the Department for Environment Food and Rural Affairs
issued an update regarding the implementation of the Large Combustion Plant
Directive (LCPD) pending a formal decision by the Government expected before the
end of this year.  The update indicated that the Government will apply emission
limit values to control emissions of sulphur dioxide, nitrogen oxides and
particulates from power stations in the UK from January 2008.  The update
repeated the European Commission's view that existing plants whose waste gases
are discharged through a common stack should be considered as a single plant for
the purposes of the LCPD, however it gave no further clarification of whether
multiple generating units each with their own separate flue (as at Eggborough)
can be treated as separate plants for the purposes of the LCPD pending further
discussions with the European Commission.

If the final decision is to consider the four units at Eggborough as a single
plant for LCPD purposes then there could be a requirement to materially restrict
the operations of the two non-FGD units from 2008 in order to comply with the
proposed emission limit values.


Contingent Liabilities

On 12 February 2004, British Energy Limited and certain of its subsidiaries
received a notice of warranty claims from the consortium which purchased the
Group's 82.4% interest in Bruce Power LP alleging breach of certain warranties
and representations relating to tax and to the condition of certain plant at the
Bruce power station.

The principal tax claim relates to the treatment of expenditure at the Bruce
Power plant during the period of the Group's part ownership and is currently
being considered by the Canadian tax authorities.  The treatment proposed by
British Energy could result in a rebate of a material amount of tax to the Group
that has never been recognised in the financial statements.  The consortium
claims that allowance of the expenditure for that period would cause it to lose
future deductions.  British Energy has rejected the tax claim and expects to
defend it if it is pursued further. The Company is confident that the amount of
the tax claim should not, in any event, materially exceed the amount of the
rebate, and that the tax claim should have no material cash flow impact on the
Group.

The claim relating to the condition of the plant is based upon alleged erosion
of certain parts of the steam generators, including the support plates, through
which boiler tubes pass, which it is alleged resulted in an extended outage of
one unit at the plant to carry out repair works and loss of revenues and costs
of approximately C$64.5m.  The consortium also claims that the alleged erosion
may reduce the operating life of the unit and/or result in further repairs
involving further losses.  British Energy has rejected the claim and expects to
defend it if it is pursued further.  No provision has been made in the financial
statements at 3 July 2005 for either claim.

Under the agreement with the consortium C$20m is retained in trust to meet any
representation and warranty claims, and this may be retained pending agreement
or determination of the claims.


Dividend Policy

The Board intends to distribute to shareholders as much of the Company's
available cash flow as prudently possible, but not until the operational
requirements of the business permit.  In addition, under the terms of the
restructuring, there are certain restrictions on or factors affecting the
Board's ability to pay dividends, including:

-    the requirement to fund a cash reserve out of the Group's post-debt service
     cash flow in order to support the Group's collateral and liquidity 
     requirements following the restructuring.  The initial target amount for 
     the cash reserve is GBP490m plus the amount by which cash employed as
     collateral exceeds GBP200m (the Target Amount).  There will be no      
     distributions to shareholders until such time as the cash reserve is at the
     required level.  As a result of the requirements to fund the cash reserve, 
     the Board is not proposing a dividend in respect of the quarter ended 3 
     July 2005 and does not currently expect to propose a dividend before the 
     financial year ending 31 March 2007.

-    the terms of the Nuclear Liabilities Agreements entered into as part of the
     restructuring also require that once the cash reserve is funded to the 
     Target Amount, the Company must make NLF Cash Sweep payments to the NLF.
     The NLF Cash Sweep payment was initially defined as 65% of the movement in 
     cash, cash equivalents and other liquid assets during the year after 
     adjusting for, among other things, certain payments made to the NLF or 
     dividends paid in the year. The requirement to make the NLF Cash Sweep 
     payment greatly reduces the amount of cash available for distribution to 
     shareholders.

-    the terms of the bonds issued as part of the restructuring contain certain 
     covenants, including a restriction that allows British Energy to pay a 
     dividend only if no event of default has occurred; and

-    the requirement for the Company to have distributable reserves.

NON-GAAP FINANCIAL MEASURES


Business Performance

Business performance excludes certain re-measurement items (see below) and is
presented as management believes that exclusion of these items provides readers
with a clear and consistent presentation of the underlying operating performance
of the Group's business.


Re-measurement

The impact of re-measurement reflects exceptional charges and other movements,
including the impact of IAS 39.  The scope of IAS 39 includes all financial
instruments i.e. loans, trade receivables, payables, investments, cash and
derivatives, as well as certain commodity contracts.  The standard requires that
all derivatives, including certain commodity contracts, are fair valued on the
balance sheet, with changes from re-measurement being recorded in the income
statement unless cash flow hedge accounting is applied.

Unrealised gains and losses in respect of commodity contracts are disclosed
separately as re-measurements.  Realised gains and losses relating to these
contracts are included in business performance.  Management considers that this
presentation best reflects the underlying performance of the business since it
distinguishes between the temporary timing differences associated with
re-measurement under IAS 39 rules and actual realised gains and losses.

Exceptional charges, by their nature, are not indicative of the underlying
operating performance of the Group.

For a reconciliation between the overall results and business performance and
details of re-measurement items, see the consolidated income statement.


Realised Price

Realised price is calculated by dividing revenue (before any re-measurement
impact, energy supply costs recharged to customers and miscellaneous income, and
net of energy purchase costs) by total output during the period.  The
adjustments to revenue allow management and investors a better understanding of
the net price that customers are paying for our electricity.


Total Operating Unit Costs

Total operating unit costs are calculated by dividing the total operating costs
(before any re-measurement, energy supply costs recharged to customers and
energy purchase costs) by total output during the period.


EBITDA

EBITDA is operating profit before interest, income taxes, depreciation and
amortisation and has been presented both including and excluding the effects of
re-measurement.  The Company has included information concerning EBITDA because
it believes that it is used by certain investors as one measure of the Company's
financial performance.  EBITDA is not a measure of financial performance under
IFRS and is not necessarily comparable to similarly titled measures used by
other companies.  EBITDA should not be construed as an alternative to operating
income or to cash flows from operating activities (as determined in accordance
with IFRS) as a measure of liquidity.

of the acquisition, also reflects the cash flows from the issue of equity by the
Company following its incorporation.


Notes to the financial statements


1. Basis of Preparation

These quarterly financial statements have been prepared on a basis consistent
with International Financial Reporting Standards (IFRS) in issue that are
effective or available for early adoption at the Group's first annual reporting
date, 31 March 2006, but do not include all the disclosures in IAS 34 on interim
reporting.  Based on these IFRSs, the Board of Directors have made assumptions
about the accounting policies expected to be adopted when the first IFRS annual
financial statements are prepared for the year ending 31 March 2006.  The
quarterly financial statements require management to make judgements, estimates
and assumptions that affect the application of policies and reported amounts of
assets and liabilities, income and expenses.

The accounting policies are consistent with those that the Directors intend to
use in the next annual financial statements as set out in the 'Restatement of
Results for Transition to International Financial Reporting Standards' as
published on 21 September 2005.  The Group's proposed accounting policies are
included in note 10.  Notwithstanding this, the IFRSs that will be effective or
available for voluntary early adoption in the annual financial statements for
the year ending 31 March 2006 are subject to change and to the issue of
additional interpretations and therefore cannot be determined with certainty.

This is the first set of quarterly results for the first three months of the
financial year for British Energy and therefore no comparative information is
provided.

To assist investors to compare the underlying financial performance of the
Group, 'business performance' income statement figures are shown before the
impact of exceptional charges and other movements arising from re-measurement.
For the first quarter the adjustments relate solely to the re-measurement of IAS
39.

References to 'British Energy' or the 'Company' are to British Energy Group plc.
  References to the 'Group' are to the Company and its subsidiaries.

The financial statements for the quarter ended 3 July 2005 are unaudited but
have been reviewed by the auditors and their report to the Company is set out
below.

These quarterly financial statements were approved by the Board of Directors on
28 September 2005.


2. Output, Revenue and Segment Information

Through consideration of our product, geographic area and regulatory
environment, the Group has concluded that it has one business, being the
generation and sale of electricity in the UK, resulting in one operating segment
of Generation and Trading.

3. Net Revalorisation Charges



                                                                               Quarter ended 2 July 2004 to

4. Taxation

There is no current tax charge in the period due to the availability of trading
losses carried forward.  The charge in the period of GBP26m before 
re-measurement and GBP16m after re-measurement consists solely of deferred tax.


5. Earnings Per Share

The basic earnings per share for the period has been calculated by dividing the
profit  after taxation by the weighted average number of ordinary shares in
issue during the period.  The diluted earnings per share calculation is based on
the weighted average of 564 million ordinary shares in issue together with the
dilutive potential of 17 million ordinary shares in respect of warrants. The
effect of the NLF Cash Sweep is not considered to be dilutive.  The adjustment
mechanism for the NLF Cash Sweep percentage set out in the Contribution
Agreement is designed such that the shareholders' interest in the Group after
taking account of the NLF Cash Sweep remains consistent.  For example, in the
event that a NLF Cash Sweep payment is made without a corresponding dividend 
then the NLF Cash Sweep percentage is diluted as if shareholders had reinvested 
a corresponding amount as new equity in the Group.

6. Pension Costs

There has been one significant change in the actuarial assumptions adopted at 3
July 2005 compared with 31 March 2005.  The discount rate used to value the
liabilities has changed from 5.5% per annum to 5.0% per annum in line with
changes in the yield on long-dated corporate bonds over the period.  The effect
of the change in the discount rate is to place a higher value on the pension
liabilities, giving rise to a significant actuarial loss over the period.


7. Contingent Assets

The Group has certain contingent assets as a result of its disposal of its 82.4%
interest in Bruce Power LP.  In addition to the consideration payable by the
consortium under the master purchase agreement, up to a further C$100m was
payable to British Energy contingent upon the restart of two of the Bruce A
units under a trust agreement (the Trust Agreement) entered into on the same
date. Had the first unit restarted by 15 June 2003, C$50m would have been
released to British Energy and an additional C$50m would have been released to
British Energy had the second unit restarted by 1 August 2003. An amount of C$5m
was to be deducted from the C$50m payable in respect of each unit for its
failure to restart by the scheduled restart date or by the first day of each
successive calendar month following the scheduled restart date. The Group
received C$20m on 22 March 2004 and C$10m on 25 May 2004 in partial
consideration under the Trust Agreement. British Energy commenced arbitration
proceedings in Ontario against the Ontario Provincial Government (the Province)
in December 2004 seeking the payment of additional consideration under the Trust
Agreement on the basis that Bruce A Units 3 and 4 restarted earlier than the
dates claimed by the Province. No additional amounts appear on our balance sheet
at 3 July 2005 because of uncertainties regarding their realisation. The amounts
recoverable in respect of the restarted units will be substantially lower than
the maximum C$100m but the amounts and timing of the payments have still to be
confirmed.


8. Contingent Liabilities

On 12 February 2004 British Energy Limited received a notice of warranty claims
from the consortium which purchased the Group's 82.4% interest in Bruce Power LP
alleging breach of certain warranties and representations relating to tax and to
the condition of certain plant at the Bruce Power Station.

The principal tax claim relates to the treatment of expenditure at the Bruce
Power Station during the period of the Group's part ownership and is currently
being considered by the Canadian tax authorities. The treatment proposed by
British Energy could result in a rebate of a material amount of tax to the Group
that has not been recognised in the financial statements. The consortium claims
that allowance of the expenditure for that period would cause it to lose future
deductions. British Energy has rejected the tax claim and expects to defend it
if it is pursued further.  The Group is confident that the amount of the claim
should not, in any event, materially exceed the amount of the rebate, and that
the tax claim should have no material cash flow impact on the Group.

The claim relating to the condition of the plant is based upon alleged erosion
of certain parts of the steam generators, including the support plates, through
which boiler tubes pass, which it is alleged resulted in an extended outage of
one unit at the plant to carry out repair works and loss of revenues and costs
of approximately C$64.5m. The consortium also claims that the alleged erosion
may reduce the operating life of the unit and/or result in further repairs
involving further losses. British Energy has rejected the claim and expects to
defend it if it is pursued further.

Under the agreement with the consortium C$20m is retained in trust to meet any
representation and warranty claims, and this may be retained pending agreement
or determination of the claims.

The Group has given certain indemnities and guarantees in respect of the
disposal of its investment in AmerGen.

The Company has given certain indemnities and guarantees in respect of its
subsidiary undertakings. No losses are anticipated to arise under these
indemnities and guarantees, provided relevant subsidiary undertakings continue
on a going concern basis.

The Group is involved in a number of other claims and disputes arising in the
normal course of business which are not expected to have a material effect on
the Group's financial position.


9. Non-adjusting Post Balance Sheet Events

On 15 September 2005, the Group announced the completion of the necessary
technical and economic evaluation regarding the potential accounting life
extension at Dungeness B.  This has resulted in the life of Dungeness B being
extended by ten years to 2018, five years beyond the extension assumed as part
of the restructuring related fair value exercise.

On 12 September 2005, the Company announced it had elected to maintain the
shutdown of two reactors at Hartlepool and to shutdown two reactors at Heysham 1
as a result of inspections to boiler closure units.  The return to service of
all four units is dependent on the successful outcome of further inspections and
a programme of work at each unit.  As a consequence, the return to service of
the four units is expected during mid to end October 2005.  As a result, the net
additional unplanned losses are currently expected to increase by 0.5 TWh to
around 1.5 TWh.  Whilst more challenging, the Company reconfirms it expects the
average annual nuclear output over the next two years to be 63 TWh.

On 21 September 2005, the Department for Environment Food and Rural Affairs
issued an update regarding the implementation of the Large Combustion Plant
Directive (LCPD) pending a formal decision by the Government expected before the
end of this year.  The update indicated that the Government will apply emission
limit values to control emissions of sulphur dioxide, nitrogen oxides and
particulates from power stations in the UK from January 2008.  The update
repeated the European Commission's view that existing plants whose waste gases
are discharged through a common stack should be considered as a single plant for
the purposes of the LCPD, however it gave no further clarification of whether
multiple generating units each with their own separate flue (as at Eggborough)
can be treated as separate plants for the purposes of the LCPD pending further
discussions with the European Commission.

If the final decision is to consider the four units at Eggborough as a single
plant for LCPD purposes then there could be a requirement to materially restrict
the operations of the two non-FGD units from 2008 in order to comply with the
proposed emission limit values.

10. Proposed IFRS Accounting Policies

The principal accounting policies as set out below are expected to be applied in
preparing the Group's results for the year ending 31 March 2006.


Basis of consolidation

The Group financial statements consolidate the financial statements of British
Energy Group plc (BEG plc) and all of its subsidiary undertakings.  BEG plc was
incorporated on 2 July 2004. As a consequence of the restructuring, under a
Scheme of Arrangement under section 425 of the Companies Act 1985, the Company
acquired British Energy plc on 14 January 2005. The restructuring has been
accounted for under the principles of acquisition accounting. The application of
acquisition accounting principles means that all the separate assets and
liabilities of British Energy plc have been recorded at fair value at the date
of acquisition with goodwill arising on the difference between the value of net
assets of British Energy plc and the acquisition consideration paid.  Only the
post acquisition results are included in the Group income statement, statement
of changes in equity and cash flow statement.

Inter-company profits, transactions and balances are eliminated on
consolidation.


Significant estimates used in applying accounting policies

The principal accounting polices adopted by BEG plc in the consolidated
financial statements are as set out below.  The application of a number of these
policies required the Group to use a variety of estimation techniques and
applying judgement to best reflect the substance of underlying transactions.

Significant factors considered when assessing the carrying value of assets
include future electricity prices, expected annual output, expected station
operating costs, remaining station lives and discount rates.  BEG plc has
determined that a number of its accounting policies can be considered
significant, in terms of the management judgement that has been required to
determine the various assumptions underpinning their application in the
financial statements presented, which, under different conditions, could lead to
material difference in these statements.  The policies where significant
judgements and estimates have been made are:
     
-    Application of business combination accounting rules;

-    Accounting for property, plant and equipment;

-    Estimation of liabilities for spent nuclear fuel and decommissioning 
     costs; and

-    Estimation of defined benefit pension scheme liabilities.


Revenue

Revenue is recognised by the Group when persuasive evidence of a sales
arrangement exists, delivery of goods or services has occurred, the amount of
revenue can be measured reliably, collectibility of the related receivable
amount is probable and the costs incurred or to be incurred in respect of the
transaction can be measured reliably.

Revenue represents the fair value of the consideration receivable for sales of
electricity and sales of other related goods and services.  It is shown net of
value added tax, electricity purchases relating to short term balancing and
hedging activities, and climate change levy. Revenue is also shown after
elimination of sales within the Group.

Wholesale generation and direct supply sales are recognised on an accruals basis
with reference to meter readings of electricity supplied. Where required, a
management estimate is included of the value of units supplied to customers
between the date of their last meter reading and the accounting period end.


Fuel Costs - Nuclear Front End


Advanced Gas-cooled Reactors (AGR)

Front end fuel costs consist of the costs of procurement of uranium, conversion
and enrichment services and fuel element fabrication. Fabrication costs comprise
fixed and variable elements. All costs are capitalised into inventory and
charged to the income statement in proportion to the amount of fuel burnt.


Pressurised Water Reactor (PWR)

All front end fuel costs are variable and are capitalised into inventory and
subsequently charged to the income statement in proportion to the amount of fuel
burnt.


Fuel Costs - Nuclear Back End


AGR

Spent fuel extracted from the reactors is sent for reprocessing and/or long-term
storage and eventual disposal of resulting waste products. Back end fuel costs
comprise:-

a)   a cost per tonne of uranium in AGR fuel, in respect of amounts payable
     on loading of fuel into any one of the AGR reactors and

b)   a rebate/surcharge against the cost mentioned in (a) above that is 
     dependent on the out-turn electricity price in the year and the amount of
     electricity generated.

The loading related cost and the rebate/surcharge is capitalised into inventory
and charged to the income statement in proportion to the amount of fuel burnt.


PWR

Back end fuel costs are based on wet storage in station ponds followed by dry
storage and subsequent direct disposal of fuel. Back end fuel costs comprise the
estimated cost of this process at current prices discounted back to current
value. Back end fuel costs are capitalised into inventory on loading and charged
to the income statement in proportion to the amount of fuel burnt.


Unburnt Fuel at Shutdown

Due to the nature of the nuclear fuel process there will be some unburnt fuel in
the reactors at station closure. The costs of this unburnt fuel (final core) is
fully provided at the balance sheet date and any changes in the carrying value
of nuclear fuel attributed to the final core are charged to the income statement
in the accounting period.


Fuel Costs - Coal (including Emission Rights)

Fuel costs for coal are determined on a weighted average cost basis.  Fuel costs
for coal also include costs of emission allowances.  The Group recognises
liabilities in respect of its obligations to deliver emission allowances to the
extent that the allowances to be delivered exceed those previously acquired by
the Group, either by allocation from the Government or a similar body or through
purchase.  Any liabilities recognised are measured based on the period end
estimates of the amounts that will be required to satisfy the net obligation.


Inventory  -  Stores

Inventory held in stores is recorded at the lower of cost and net realisable
value.


Employee Benefits - Post Retirement Benefit Obligations

The Group provides for pension costs in accordance with IAS 19 (2004) 'Employee
Benefits'. Contributions to the Group's defined benefit pension schemes are
assessed by qualified actuaries. BEG plc operates two separate pension
arrangements in the UK within the Electricity Supply Pension Scheme, which is a
defined benefit scheme.  Pension scheme assets are measured using market values,
which for securities is based on bid price values.  Pension costs are assessed
using the projected unit method so that the cost of providing pensions is
charged to the income statement in a manner which spreads the service cost over
the expected service lives of employees.  The pension obligation is measured as
the present value of the estimated future cash outflows, discounted using the
interest rates on UK government securities of appropriate maturity.  The
expected return on the schemes' assets and the increase during the period in the
present value of the schemes' liabilities arising from the passage of time are
included in other finance income. Actuarial gains and losses are recognised
immediately within the Statement of Recognised Income and Expense.

The capital cost of ex-gratia and supplementary pensions is charged to the
income statement, to the extent that the arrangements are not covered by the
surplus in schemes, in the accounting period in which they are granted.

Certain additional unfunded retirement benefits are provided to eligible
employees.  The cost of providing such benefits is charged to the income
statement as they accrue.


NLF Funding Arrangements

Under the arrangements with the Secretary of State the NLF will fund, subject to
certain exceptions, the Group's qualifying uncontracted nuclear liabilities and
qualifying decommissioning costs.  To the extent there is any surplus remaining
in the NLF after all obligations have been discharged, this amount will be paid
to the Secretary of State. The Group is responsible for funding certain excluded
or disqualified liabilities and will, in certain circumstances, be required to
compensate or indemnify the NLF and the Secretary of State in relation to such
liabilities. The Group's obligations under these arrangements with the Secretary
of State are guaranteed by certain companies within the Group.

In consideration for the assumption of these liabilities by the Secretary of
State and the NLF, British Energy Holdings plc (a subsidiary of BEG plc) issued
GBP275m in New Bonds to the NLF at RED.  The Group will also make the following
payments to the NLF (i) an annual contribution (NLF Cash Sweep payment)
initially equal to 65% of the British Energy Group's adjusted net cash flow,
adjusted for certain corporate actions but never to exceed 65% (ii) fixed
decommissioning contributions equal to GBP20m per annum (indexed to RPI but
tapering off as the nuclear power stations are currently scheduled to close);
and (iii) GBP150,000 (indexed to RPI) for every tonne of uranium in PWR fuel
loaded into the Sizewell B reactor after RED.

The NLF has the right from time to time to convert all or part of the NLF Cash
Sweep payment into convertible shares of the Company. On a full conversion, the
NLF would hold up to 65% of the thereby enlarged equity share capital of the
Company. However, the terms of the Convertible Shares include a limit on the
voting rights of such shares equal to a maximum of 29.9% whilst held by the NLF.

The annual NLF Cash Sweep payment can only be determined after the end of the
financial year and is contingent based on cash generation in the year.
Therefore, it is only recognised and provided for when it becomes determinable
and not in any interim financial periods.  It will be recorded as an operating
cost of the applicable financial year.  The annual NLF Cash Sweep payment
becomes payable twenty business days after publication of the annual report and
accounts.

The fixed decommissioning obligations of annum have been recorded as a liability
on the balance sheet at their discounted value and disclosed as the NLF
liability.  The NLF liability is reduced as payments are made to the NLF.  Each
year the financing charges in the income statement include the revalorisation of
NLF liabilities required to discharge one year's discount from the liability.

PWR fuel loaded after RED will increase the qualifying nuclear liability
recognised for back end PWR fuel costs as set out above and will increase the
NLF receivable by a corresponding amount.  The difference between the payment of
GBP150,000 (indexed to RPI) per tonne made to the NLF on the loading of PWR fuel
and the increase in the liability recognised, and therefore the increase in NLF
receivable, is recorded as a back end fuel cost or credit as appropriate in the
year of loading.


Goodwill

Goodwill arising on acquisitions represents the excess of the fair value of the
consideration at acquisition compared to the fair value of the identifiable net
assets acquired. Goodwill is capitalised as an intangible asset on the balance
sheet. Following initial recognition, goodwill is measured at cost less any
accumulated impairment losses.  Goodwill balances are assessed for impairment at
least annually and at other balance sheet dates if there is any indication of
impairment.


Taxation

The tax expense represents the sum of the tax currently payable and deferred
tax.

The tax currently payable is based on taxable profit for the year.  Taxable
profit differs from net profit as reported in the income statement because it
excludes items of income and expense that are taxable or deductible in other
years and it further excludes items that are never taxable or deductible.  The
Group's liability for tax currently payable is calculated using tax rates that
have been enacted or substantively enacted by the balance sheet date.

The tax expense relating to items recognised directly in equity are recognised
in equity and not in the income statement.

Deferred tax is provided in full, using the liability method, on temporary
differences, carry-forward of unused tax assets and unused tax losses, arising
between the tax bases of assets and liabilities and their carrying amounts in
the consolidated financial statements.

Deferred tax assets are recognised to the extent that it is probable that future
taxable profit will be available against which the temporary differences can be
utilised. The carrying amount of deferred tax assets is reviewed at each balance
sheet date and reduced to the extent that it is no longer probable that
sufficient taxable profit will be available to allow all or part of the deferred
tax asset to be utilised.


Property, Plant and Equipment and Depreciation, including Decommissioning Costs

Property, plant and equipment comprises assets acquired or constructed by the
Group. Property, plant and equipment (other than assets in the course of
construction) are stated in the balance sheet at cost less accumulated
depreciation. The fair value of property, plant and equipment acquired as a
result of the restructuring has been deemed to be the cost amount recognised at
that date.  Cost includes expenditure that is directly attributable to the
acquisition of the items. Accumulated depreciation includes additional charges
made where necessary to reflect impairment in value.

Assets in the course of construction are stated at cost and not depreciated
until brought into commission.

The charge for depreciation of property, plant and equipment is based on the
straight line method so as to write off the costs of assets, after taking into
account provisions for diminution in value, over their estimated useful lives.
The asset lives adopted are reviewed annually and for the year ended 31 March
2006 were:

AGR power stations                                          5 - 17 years
PWR power station                                           29 years
Coal power station                                          10 years
Other buildings                                             30 years
Other plant and equipment                                   18 months - 5 years

Expenditure incurred to replace a component of an item of property, plant and
equipment that is accounted for separately, or to improve its operational
performance is included in the asset's carrying amount or recognised as a
separate asset as appropriate when it is probable that future economic benefits
in excess of the originally assessed standard of performance of the existing
asset will flow to the Group and the cost of the item can be measured reliably.
Expenditure to improve safety or in order to meet increased regulatory standards
is also capitalised. Expenditure on major inspection and overhauls of production
plant is capitalised, within other plant and equipment, when it meets the asset
recognition criteria and is depreciated over the period until the next outage.
Interest on major capital projects is included in the cost of the fixed asset
from the date of cash settlement until the date of commissioning. Asset
additions are depreciated over the remaining useful life of the related asset.

The estimated costs for decommissioning the Group's nuclear power stations and
restoring the sites on which they are located are capitalised as part of the
cost of construction and are depreciated over the same lives as the stations.
These estimated costs are discounted having regard to the time scale whereby
work will take place over many years after station closure.  The estimated costs
include the demolition and site clearance of the stations' radioactive
facilities and the management of waste.

Major spare parts are classified as property, plant and equipment and assigned
to individual stations when they are expected to be utilised over more than one
period. They are depreciated using the applicable station lifetime estimate.

Other expenditure, including that incurred on preliminary studies and on the
initiation of new technologies not yet adopted, is charged to the income
statement as incurred. All other maintenance, repairs and renewals are charged
to the income statement during the financial period in which they are incurred.

Gains and losses on the disposal of property, plant and equipment are included
in operating profit/loss.


Intangible Assets (excluding Goodwill)

The costs of acquired computer software costs are capitalised on the basis of
the costs incurred to acquire and bring the specific software in to use, and are
amortised over their estimated operational lives for a maximum of five years.
Costs directly associated with the development of computer software programmes
that are expected to generate economic benefits over a period in excess of one
year are also capitalised and amortised over their estimated operational lives.


ROCs and LECs are classified as intangible assets and are valued at cost.


Impairment of Tangible and Intangible Assets (excluding Goodwill)

At each balance sheet date, the Group reviews its tangible and intangible assets
(excluding goodwill) to determine whether there is any indication that those
assets may have suffered an impairment loss. If any such indication exists, the
recoverable amount of the asset is estimated to determine the extent of any
impairment loss.


NLF Receivable and Nuclear Liabilities Receivable

The Government indemnity is provided to indemnify any future shortfall on NLF
funding of qualifying uncontracted nuclear liabilities (including PWR back-end
fuel services) and qualifying nuclear decommissioning costs.

The NLF receivable asset recognised represents the aggregate value of the NLF
and the Government indemnity such that the receivable equals the present value
of the associated qualifying nuclear liabilities.

The Government indemnity is also provided to cover services for spent AGR fuel
loaded pre-restructuring.  The nuclear liabilities receivable is recognised in
respect of the indemnity such that the receivable equals the present value of
the associated qualifying nuclear liabilities.

The NLF receivable and the nuclear liabilities receivable are stated in the
balance sheet at current price levels, discounted at a long-term real rate of
interest of 3% per annum to take account of the timing of payments.  Each year
the financing charges in the income statement include the revalorisation of
these receivables required to match the revalorisation of the nuclear
liabilities.


Nuclear Liabilities

Nuclear liabilities represent provision for the Group's liabilities in respect
of the costs of waste management of spent fuel and nuclear decommissioning. The
provisions represent the Directors' best estimates of the costs expected to be
incurred. They are calculated based on the latest technical evaluation of the
processes and methods likely to be used, and reflect current engineering
knowledge. The provisions are based on such commercial agreements as are
currently in place, and reflect the Directors' understanding of the current
Government policy and regulatory framework. Given that Government policy and the
regulatory framework on which our assumptions have been based may be expected to
develop and that the Directors' plans will be influenced by improvements in
technology and experience gained from decommissioning activities, liabilities
and the resulting provisions are likely to be adjusted.

In matching the costs of generating electricity against the income from sales,
accruals are made in respect of the following:

     
a)   Fuel costs - back end

The treatment of back end fuel costs in the income statement has been dealt with
under the accounting policies for fuel costs above. These nuclear liabilities
cover reprocessing and storage of spent nuclear fuel and the long-term storage,
treatment and eventual disposal of nuclear waste. They are based, as
appropriate, on contractual arrangements or the latest technical assessments of
the processes and methods likely to be used to deal with these obligations under
the current regulatory regime. Where accruals are based on contractual
arrangements they are included within creditors. Other accruals are based on
long-term cost forecasts which are reviewed regularly and adjusted where
necessary, and are included within provisions.


b)   Decommissioning of nuclear power stations

The financial statements include provision for the full cost of decommissioning
the Group's nuclear power stations. Provision is made on the basis of the latest
technical assessments of the processes and methods likely to be used for
decommissioning under the current regulatory regime.

Accruals and provisions for back end fuel costs and decommissioning are stated
in the balance sheet at current price levels, discounted at a long-term real
rate of interest of 3% per annum to take account of the timing of payments. Each
year the financing charges in the income statement include the revalorisation of
liabilities required to discharge one year's discount from provisions made in
prior years and restate these provisions to current price levels.


Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash on hand, with banks and short-term
deposits with a maturity of three months or less. Restricted cash primarily
consists of cash pledged as collateral.


Financial Instruments


Implementation of IAS 32 and IAS 39

The Group has applied IAS 32 and the full version of IAS 39 in the financial
year ending 31 March 2006 rather than the European Union ('EU') adopted
regulation of November 2004 which endorsed IAS 39 with the exception of certain
provisions relating to (i) the use of the full fair value option for liabilities
and (ii) hedge accounting. Applying the full version of the standard has no
impact on the group's financial statements.

In accordance with the transitional arrangements set out in IFRS 1, the Group
has not restated the prior period's comparative figures to show the effect of
IAS 32 and IAS 39. For the period ended 31 March 2005, financial instruments
continue to be accounted for in accordance with the Group's previous policies
for financial instruments under UK GAAP.


Recognition, classification and subsequent measurement of financial assets and
liabilities

IAS 39 requires that all financial assets be initially recognised at fair value
in the balance sheet with changes in fair value reported through the income
statement. Exceptions apply to assets classified as loans and receivables and
held-to-maturity investments, which are measured at amortised cost using the
effective interest method, and also to equity investments in instruments whose
fair value can not be reliably measured, which are recognised and measured at
cost.

Financial liabilities are measured at amortised cost using the effective
interest method. The Group measures all debt instruments initially at fair
value, and this is taken to be the fair value of the consideration received.

Transaction costs (any such costs incremental to and directly attributable to
the issue of the financial instruments) are included in the calculation of the
effective interest rate and are, in effect, amortised through the income
statement over the life of the instrument.  Derivative instruments, and
commodity contracts that fall within the scope of IAS 39, are carried at fair
value with special rules applying to all financial instruments which form part
of a hedging relationship.


Accounting for derivatives and commodity contracts

The Group's activities expose it primarily to risks associated with electricity
generation, the purchase of fuel for use in the generation process, and the
supply of electricity to end customers in both the wholesale and retail markets.
The Group follows a trading strategy of selling forward a proportion of the
Company's output to reduce the Group's exposure to potential falls in the market
price of electricity. The use of derivative financial instruments occurs
primarily within the Group's electricity trading and coal procurement
activities.

The Group's accounting objective is to report earnings results that are
consistent with its operational strategies.  As such, the Group aims to
recognise the earnings effects of derivative transactions executed to hedge
economic business risks in the income statement in the period in which the
economically hedged operational activity affects earnings.  The Board has
endorsed the use of derivative financial instruments as hedging tools and the
Group uses derivative and non-derivative financial instruments to manage its
exposures. Physical and financially settled instruments are held by the Group to
match offsetting physical positions and are not held for financial trading
purposes.

Where commodity contracts, such as electricity and fuel, are entered into in
accordance with the Group's own purchase, sale or usage requirements they are
accounted for on an accruals basis following delivery of the commodity and are
thereby excluded from the scope of IAS 39.  Amounts payable or receivable in
respect of these contracts are recorded within trade creditors and trade
receivables respectively. Where a commodity contract is not entered in to or
does not continue to be held to meet the Group's own purchase, sale or usage
requirements the recognition and measurement requirements of IAS 39 are applied.

Derivative financial instruments are initially recognised at fair value and all
changes in fair value are subsequently accounted for through the income
statement unless the derivative qualifies as a hedging instrument.

Changes in the fair value of derivative financial instruments that are
designated and are effective as hedges of future cash flows are recognised
directly in equity, in the cash flow hedge reserve, and the ineffective portion
of the hedge is recognised immediately in the income statement.

The Group designates derivatives as hedging instruments when it is expected that
there will be a high inverse correlation between the changes in fair value of
the hedging instrument and the changes in the fair value of the cash flows of
the hedged item. This is measured primarily using the dollar offset method. Such
correlation is required to be within the limits of 80% to 125% for hedge
accounting to be permitted. Prospective and retrospective testing is carried out
on a regular basis, at least on each reporting date, to establish whether the
assumptions and application criteria for hedge accounting going forward continue
to be supported. The Group discontinues hedge accounting where the hedging
relationship correlation is outside the required parameters.


Derivative instruments are de-designated from a hedge relationship when:

-    The hedging instrument or item expires or is settled;

-    The forecast transaction is no longer considered to be highly probable; and

-    The hedging instrument no longer qualifies for hedge accounting under
     IAS 39 rules.

At that time, any cumulative gain or loss on the hedging instrument recognised
in equity is retained in equity until the forecast transaction is settled.  If a
hedged transaction is no longer expected to occur, the net cumulative gain or
loss recognised within equity is transferred to the income statement of the
period.


Valuation of commodity contracts and derivatives

The group's valuation policy for derivative and other financial instruments is
to maximise the use of quoted prices from active trading markets.

Futures, swaps, and forward agreements are valued against the appropriate
market-based curves. Three types of curves (price, volatility and correlation)
may be required depending upon the liquidity of the market and type of product
traded forward price curves are developed using  market  prices  from
independent  sources  for  liquid  commodities,  markets  and  products  and
modelled  for  illiquid commodities, markets and products. Volatility curves are
modelled for open positions in illiquid markets and implied volatility curves
are developed from actively traded options. Correlation curves are developed
using either implied correlations or using historical forward correlations and
other relevant market data.

Where necessary, structured transactions are disaggregated into their traded
core components, and each component is valued against the appropriate
market-based curves.  The fair value of a structured deal is the summation of
the fair value of its core components.

Purchase contracts are valued against the quoted bid price and sales contracts
are valued against the quoted offer prices, with no provisions made for
liquidity. Valuation adjustments are made for the time value of money, which is
applied to all contracts, and credit risk, which will be applied where
applicable.


Embedded derivatives

The Group also evaluates contracts for embedded derivatives, and considers
whether any embedded derivatives have to be separated from the underlying host
contract and accounted for separately in accordance with IAS 39 requirements.
Where embedded derivatives have terms that are not closely related to the terms
of the host contract in which they are included, they are accounted for
separately from the host contract as derivatives, with changes in the fair value
recorded in the income statement, to the extent that the hybrid instrument is
not already accounted for at fair value.

Embedded derivatives are valued either by directly valuing the derivative
element in line with the processes described above or by valuing the embedded
derivative as the difference between the value of the hybrid instrument and the
host contract (excluding the derivative element).


Offsetting of derivative assets and liabilities

The Group offsets a financial asset and a financial liability and reports the
net amount only when the Group has a legally enforceable right to set off the
amounts and intends either to settle on a net basis, or to realise the asset and
settle the liability simultaneously.


Impact on Effective Tax Rate

Income tax for interim reporting periods is calculated by applying an estimate
of the annual effective tax rate to the interim result excluding IAS 39
adjustments, and by calculating tax at the standard rate for the IAS 39
adjustments arising within the period.


Share-based Payments

BEG has two share compensation schemes, a Long Term Deferred Bonus Plan, and a
Share Incentive Plan.  BEG plc accounts for its share compensation schemes in
accordance with IFRS 2 'Share-based Payments' using the Black-Scholes option
pricing model under which fair value is calculated for the share compensation
schemes and updated at subsequent balance sheet dates.

The fair value of the share compensation schemes is charged to the income
statement over the period from the date the schemes were granted to the date at
which the compensation is expected to vest on the employees. The corresponding
credit is included in Shareholders' Equity.  The Group issues equity-settled
share-based payments to certain employees under the terms of the Group's various
employee share compensation schemes. Equity-settled share-based payments are
measured at fair value at the date of grant. The fair value determined at the
grant date of equity-settled share-based payments is expensed on a straight-line
basis over the vesting period, based on an estimate of the shares that will
ultimately vest.

INDEPENDENT REVIEW REPORT TO BRITISH ENERGY GROUP PLC

Introduction

We have been instructed by the company to review the financial information for
the quarter ended 3 July 2005 which comprises the consolidated income statement,
consolidated balance sheet, consolidated statement of recognised income and
expense, consolidated statement of changes in equity, consolidated statement of
cash flows, and associated notes.  We have read the other information contained
in the quarterly report and considered whether it contains any apparent
misstatements or material inconsistencies with the financial information.

Directors' responsibilities

The quarterly report, including the financial information contained therein, is
the responsibility of, and has been approved by the directors. The directors are
responsible for preparing the interim report in accordance with the Listing
Rules of the Financial Services Authority.

As disclosed in note 1, the next annual financial statements of the group will
be prepared in accordance with accounting standards adopted for use in the
European Union. This quarterly report has been prepared in accordance with the
basis set out in Note 1.

The accounting policies are consistent with those that the directors intend to
use in the next annual financial statements. As explained in note 1, there is,
however, a possibility that the directors may determine that some changes are
necessary when preparing the full annual financial statements for the first time
in accordance with accounting standards adopted for use in the European Union.
The IFRS standards and IFRIC interpretations that will be applicable and adopted
for use in the European Union at 31 March 2006 are not known with certainty at
the time of preparing this interim financial information.

Review work performed

We conducted our review in accordance with guidance contained in Bulletin 1999/4
issued by the Auditing Practices Board for use in the United Kingdom. A review
consists principally of making enquiries of group management and applying
analytical procedures to the financial information and underlying financial data
and, based thereon, assessing whether the disclosed accounting policies have
been applied. A review excludes audit procedures such as tests of controls and
verification of assets, liabilities and transactions. It is substantially less
in scope than an audit and therefore provides a lower level of assurance.
Accordingly we do not express an audit opinion on the financial information.
This report, including the conclusion, has been prepared for and only for the
company for the purpose of the Listing Rules of the Financial Services Authority
and for no other purpose. We do not, in producing this report, accept or assume
responsibility for any other purpose or to any other person to whom this report
is shown or into whose hands it may come save where expressly agreed by our
prior consent in writing.


Review conclusion

On the basis of our review we are not aware of any material modifications that
should be made to the financial information as presented for the quarter ended 3
July 2005.

NLF

An independently administered fund into which the Group makes contributions to
cover all qualifying uncontracted nuclear liabilities including costs of
decommissioning nuclear power stations and PWR back end fuel costs.


Operating Unit Cost

Calculated by dividing the total operating cost, excluding re-measurement,
energy supply costs recharged to customers and energy purchases, by total
output.


Outage (Planned and Unplanned)

A period during which a reactor is shut down. The periodic shutdown of a reactor
including for maintenance, inspection and testing or, in some cases, for
refuelling is known as a planned outage. In the UK, some planned outages are
known as statutory outages and are required by the conditions attached to the
nuclear site licence needed to operate the station. Unscheduled shutdown of a
reactor for a period is known as an unplanned outage.


PiP

The Performance Improvement Programme.


PWR (Pressurised Water Reactor)

The most recent type of nuclear reactor to be constructed in the UK which uses
pressurised water as both the coolant and the moderator.


Quinquennial Review

The five-yearly review of the assumptions underlying the Group's provision for
certain nuclear liabilities.


Realised Price

This is the average price of electricity sold during the relevant period. It is
calculated by dividing revenue, excluding re-measurement impact, energy supply
costs recharged to customers and miscellaneous income, and net of energy
purchase costs, by total output during the period.


Renewable Obligation Certificates

Revalorisation

Revalorisation arises because nuclear liabilities are stated in the balance
sheet at current price levels, discounted at 3% per annum from the eventual
payment dates. The revalorisation charge is the adjustment that results from
restating these liabilities to take into account the effect of inflation in the
year and to remove the effect of one year's discount as the eventual dates of
payment become one year closer. Revalorisation charges arise in respect of the
fixed decommissioning obligation to reflect the unwinding of the discount for
the period. A revalorisation credit arises in respect of movements in the value
of nuclear liabilities and the NLF receivable to take account of the underlying
movement in nuclear liabilities.


Statutory Outage
