Our prime focus continues to remain on improving our operational reliability. - Operating profit* of GBP135m for the half year, GBP58m for the second quarter. - EBITDA* of GBP227m for the half year, GBP106m for the second quarter. - Results reflect the benefit of higher electricity prices with an operating margin of GBP3.9/MWh at contracted summer prices. - Total output for the half year was 33.1 TWh (nuclear 30.6 TWh, coal 2.5 TWh), up from 31.7 TWh in the first half of financial year 2004/05 (nuclear 28.7 TWh, coal 3.0 TWh). - Total output for the current financial year to 9 December 2005 was 44.1 TWh (nuclear 40.1 TWh, coal 4.0 TWh) after total unplanned losses for the period to 9 December 2005 of 9.6 TWh. - As announced on 25 November 2005, due to extensive inspections at Hartlepool and Heysham 1 and the need to replace the generator stator on one unit at Hartlepool, we expect that nuclear output for the financial year 2005/06 is unlikely to exceed 61 TWh. We expect nuclear output for the financial year 2006/07 to be around 63 TWh. - Realised price was GBP25.0/MWh for the half year, compared to GBP24.7/MWh in the first quarter. - As at 9 December 2005, the Company had fixed contracts in place for approximately 95% of planned output for the financial year 2005/06 at an average price of GBP32.5/MWh. Financial year 2006/07 book approximately half fixed at an average price of approximately GBP35/MWh excluding 5 TWh of capped contracts. - Operating cash inflow from operations was GBP150m for the half year. Net debt decreased in the half year by GBP113m to GBP107m. Cash and liquid funds were GBP569m and collateral requirements were GBP274m. Collateral requirements as at 9 December 2005 were GBP419m. - Investment in plant is expected to exceed GBP250m including extra investment in strategic spares for the financial year 2005/06. - The NLF Cash Sweep percentage was 64.69% as at 2 October 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 interim financial statements in line with the Group's accounting policy. An accrual will be made at 31 March 2006 for any NLF Cash Sweep payment. - 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 half year. Bill Coley, British Energy CEO said: "We continued to deliver good financial performance through the half year benefiting from higher electricity prices. We are disappointed with the recent outages at Hartlepool and Heysham 1 which have impacted our projection of output for the year, but see continuing improvements in operating metrics as a result of our performance improvement programme. The British Energy team remains keenly focused on the long-term by making the investments in the plant and people to improve reliability and maximise output."

This is the first time since completion of the restructuring of the Group on 14 January 2005 that British Energy Group plc has published half year results. Therefore this report does not contain any comparative financial information but, where appropriate, does contain comparative non-financial information. Items marked * represent the results of operations adjusted to reflect the results before exceptional charges and other movements arising from re-measurement. During the half year and quarter there were no exceptional charges. For the half year and quarter the re-measurement adjustments relate solely to the re-measurement impact of IAS 39 on the results for the half year and quarter. British Energy believes that the adjusted measures provide a better indication of the underlying business performance. Certain defined terms used in these half year results are contained in the Glossary at the back of this statement.

CHAIRMAN'S STATEMENT The first half has demonstrated improvement in financial performance largely due to rising electricity prices and to an improvement in output compared to last year. The performance improvement programme has progressed well. PiP is evolving into a programme of continuous improvement which we believe will improve the reliability of our power stations. An increase in output, however, will take time as we complete the necessary investment to improve the materiel condition of the plant. The reduction in our output target for the current year to a level unlikely to exceed 61 TWh as announced on 25 November 2005 reflects this and while disappointing is largely due to unplanned boiler closure unit inspections at Heysham 1 and Hartlepool together with the need to replace the generator stator on one unit at Hartlepool. The current energy environment provides both opportunities and challenges for British Energy. The Group has improved substantially the fixed prices for expected output this year in a period when energy markets continue to be highly volatile. This requires us to remain focused on managing cash and collateral. British Energy welcomes the Government's Energy Review and we look forward to the role we can play in helping the UK meet its energy requirements. The UK needs a balanced energy policy and it is the role of Government to define the framework. Nuclear power can make an important contribution to UK targets on climate change, security of supply and competitiveness. We have continued to strengthen the management team throughout the half year. Peter Wakefield joined as Safety and Technical Director in April 2005. Peter was previously Generation and Safety and Assurance Manager for Eskom in South Africa and has extensive experience in all aspects of nuclear power plants. Recent WANO award winner Peter Prozesky has also joined from Eskom as Head of Operations East, bringing with him over 25 years of operational and project management skills. We will continue to build the strength of our team with an aim of achieving world-class nuclear operations. Safety and environmental performance remain key priorities as can be seen in the fuller discussion later in this report. However, as reported in our last Report and Accounts, there was a fatal accident in July 2005 at Eggborough power station where one of our contractors sadly lost his life. We continue to work with our contractors to improve working practices. 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 half year. The Board of Directors does not currently expect to propose a dividend before the financial year ending 31 March 2007. The Board is committed to maximising shareholder returns after considering the Company's need to improve financial stability, maintain an appropriate capital structure, make appropriate investments in the plant and meet the collateral requirements for the Group. CHIEF EXECUTIVE'S REVIEW British Energy completed a good first half of the financial year ending 31st March 2006 benefiting from rising electricity prices. Operating profit rose to GBP135m for the half year. EBITDA rose to GBP227m, reflecting an increase in average realised price to GBP25.0/MWh. Earnings per share were 11.9p. Cash flow from operations in the half year improved substantially at GBP150m compared to the equivalent period last year, reflecting higher realised prices for summer power contracts. This resulted in a net debt position at 2 October 2005 of GBP107m after debt of GBP676m. Total output was 33.1 TWh for the half year following marginally lower than expected output for the second quarter of 15.7 TWh largely due to outages related to Heysham 1 and Hartlepool and planned maintenance activity at Eggborough. We remain focused on improving the operational reliability of our plant, through carefully targeted investment. Total output to 9 December 2005 was 44.1 TWh of which nuclear output was 40.1 TWh. Unplanned losses to 9 December 2005, excluding net additional unplanned losses due to boiler closure units at Heysham 1 and Hartlepool of 2.4 TWh, were 7.2 TWh. We will continue to work with the regulator regarding additional inspection of the boiler closure units at Heysham 1 and Hartlepool. We have continued to make good progress with the investment programme bringing total investment in plant to GBP102m for the half year. Five statutory outages have been completed to date with one further outage scheduled to be completed prior to 31 December 2005. The out-turn of these statutory outages and higher unplanned losses will lead to higher costs. We now expect that investment in plant will exceed GBP250m including extra investment in strategic spares for the financial year 2005/06. The performance improvement programme is being embedded into the business as a programme of continuous improvement and has continued to make the significant improvements in our people, processes and the systems required to achieve world-class operations. Many functions are now in place within the stations and senior personnel hires have been completed. Key performance indicators across many nuclear performance metrics have improved in the half year. Trading completed a good half year compared to the equivalent period last year reflecting higher electricity prices for summer power contracts. The realised price improved in the second quarter reflecting rising summer power prices and good management of balancing costs despite outages at Heysham 1 and Hartlepool. The trading book has progressed well during the third quarter with the focus remaining on managing collateral and exposure related to unreliability in output in a highly volatile electricity market. On 15 September 2005, the Group announced its decision to extend the accounting life of Dungeness B by ten years to 2018. This is a result of a thorough technical and economic assessment of the station working in consultation with the Nuclear Decommissioning Authority and reflects our intention to seek life extensions for all our power stations where safe and profitable to do so. The life extension at Dungeness B will ensure continued contribution to reducing CO2 emissions in the UK. Outlook The financial year will continue to be a year of consolidation in operational performance. Many of the organisational changes required for the improvement programme are in place. We will continue to strengthen the team at the stations. There have been improvements in unplanned losses before taking into account the extended outages at Heysham 1 and Hartlepool. We expect underlying performance to continue throughout the remainder of the year. One unit at Hartlepool is expected to remain shutdown until March 2006 for replacement of the generator stator. This, in association with the previous boiler closure unit inspections at Heysham 1 and Hartlepool caused us to conclude that nuclear output is unlikely to exceed 61 TWh for the year 2005/06. As we have previously communicated, improvement in performance is expected to take time due to the requirement to invest in the materiel condition of the stations. Much of the work performed in the current year is required to stabilise output due to under-investment in prior years. This is expected to continue over the next two financial years during the remaining statutory outages. This remedial work may also impact on the length of statutory outages and lead to higher costs. There is also a requirement to undertake further inspections of Heysham 1 and Hartlepool boiler closure units in the financial year 2006/07. Accordingly, we expect nuclear output for the financial year 2006 /07 to be around 63 TWh. The electricity markets continue to show considerable volatility. The focus will remain on improving financial stability and collateral management. We have benefited from recent price rises and plan to progressively close out the remainder of the trading book for 2005/06. OPERATIONAL REVIEW Plant Output and Performance Nuclear output was 14.9 TWh (71% load factor) for the quarter and 30.6 TWh (72% load factor) for the half year. The nuclear output for the quarter ended 30 September 2004 was 13.7 TWh (65% load factor) and for the six months ended 30 September 2004 was 28.7 TWh (68% load factor). During the quarter statutory outages were completed at Heysham 1 and Hunterston B and one started at Dungeness B. Since successfully completing its statutory outage in the first quarter, Sizewell B has operated continuously at full power. There were planned outages amounting to 2.3 TWh of lost output in the quarter and 6.1 TWh for the half year. Unplanned losses for the quarter were 3.7 TWh and 6.0 TWh for the half year, including outage overruns at Heysham 1, Hunterston B and Sizewell B. On 31 October 2005, the Company announced that the two units at Heysham 1 had returned to service following boiler closure unit work and by 15 November 2005, the two units at Hartlepool had returned to service. The net additional unplanned loss related to these outages was 2.4 TWh. Subsequent to its return to service, an issue with the generator stator on one unit at Hartlepool resulted in a shutdown that is expected to last until March 2006. Output from our coal-fired power station at Eggborough was 0.8 TWh during the quarter and 2.5 TWh for the half year. For the quarter ended 30 September 2004, the output was 1.6 TWh and for the six-month period ended 30 September 2004, the output was 3.0 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. In addition, the output level reflects planned maintenance work completed during the quarter. Inspections carried out during the Unit 4 outage at Eggborough 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. 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. 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, and this has since been confirmed in writing by the European Commission. Discussions with the Government are continuing but if this interpretation is maintained, it means that there could be a requirement to either modify the plant or materially restrict the operations of the two non-FGD units at Eggborough from 2008 in order to comply with the proposed emission limit values. Discussions are taking place with lending banks regarding their 2010 Option. Operational Update As part of its ongoing work to achieve improved operational performance, the Company has developed a number of performance improvement processes and has broadly completed the integration of those processes into the stations. Implementation of the programme is progressing well, with completion expected in 2006/07. Effectiveness reviews of the processes are being undertaken, in addition to the Company's ongoing monitoring of a number of key performance indicators. The Company's non-outage defect backlog has reduced by 27% for the half year as a result of focusing on equipment reliability, work management and an improved operational focus. Both nuclear reportable events and unplanned automatic trips continue to show an improvement in the half year. In the course of designing the Company's improvement programme, we have sought input from external experts. Hartlepool received a positive assessment in the quarter that builds on recent good assessments received at other stations. The Company's human performance programme was also recognised as being at the forefront of such programmes in Europe and we have recently conducted a workshop for other European nuclear utilities. We have continued to make good progress with the investment programme bringing the total investment in plant, projects, major repairs and strategic spares to GBP102m for the half year. The main investment in plant included additional boiler safety work at Hartlepool and Heysham 1, turbine work at Heysham 1, low pressure rotor refurbishment at Heysham 2 and Hunterston B, generator transformer refurbishment at Hartlepool and cast iron replacement at Hinkley Point and Hunterston B. Work continued on the planned reactor pressure vessel head replacement at Sizewell B and FGD system and low nitrous oxide burners at Eggborough. Investment has also been made in strategic spares, including generator rotors and transformers. 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 contractors have increased during the quarter and half year largely due to an increased number of accidents involving contractors. A much greater focus has been put on helping and supporting our contractor partners improve their safety performance. We remain absolutely committed to safety and ensuring the safety of our staff, contractors and the general public. The environmental performance of the Group also continues to remain a fundamental priority of the Company. Environmental performance indicators in the year to date are ahead of the Group's expectations. 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 managing the UK's nuclear legacy. British Energy welcomes the opportunity to take part in this consultation and has responded with its views to the NDA. Quinquennial Review The quinquennial review of our nuclear liabilities is underway and the results of this review will be finalised in the New Year. The review may result in a significant change in value of the nuclear liabilities due to changes in strategy and cost estimates. However, as a result of the arrangements with the NLF and Government, any change in value of the nuclear liabilities will be offset in our balance sheet by an equal and opposite change in the value of the NLF receivable. TRADING REVIEW Trading Position The forward contract for baseload electricity for winter 2005/06 delivery closed at GBP49.4/MWh on 30 September 2005, well below the peak of over GBP67/MWh seen in mid-July. The forward market in electricity continues to show considerable volatility, with baseload power for 2006/07 delivery trading between GBP45/MWh and GBP55/MWh over the quarter. As at 9 December 2005, the Company had fixed price contracts in place for approximately 95% of planned output for the financial year 2005/06 at an average contract price of GBP32.5/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 for planned output over the remainder of the year, expected to be around GBP1.0/MWh. The Company intends to progressively close out its remaining exposure to market prices for the financial year 2005/06 in the shorter term markets subject to limits on trading collateral. Good progress has been made in building the fixed price contract position for 2006/07, with approximately half of planned output fixed to date at a price of approximately GBP35/MWh. This price excludes the impact of capped price arrangements of approximately 5 TWh at around GBP30/MWh. Realised price was GBP25.0/MWh for the half year and GBP25.3/MWh for the quarter. Collateral The Group's strategy for securing part of its income through fixed price contracts means that in a volatile electricity market collateral requirements are also volatile. The Group's ability to secure longer term certainty on its income is limited by the amount of collateral and headroom available. The recent increase in electricity prices to unprecedented levels has given rise to increased collateral requirements, with a corresponding constraint on cash headroom. The Group actively manages its use of collateral by selling electricity through a number of routes to market including through its direct supply business (to large industrial and commercial customers) which requires minimal collateral and also through the use of financial products and low collateral contractual structures. We have recently secured zero collateral trading lines for up to 8 TWh over two years. Collateral requirements increased by GBP58m from GBP216m at 31 March 2005 to GBP274m at 2 October 2005. Collateral requirements as at 9 December 2005 were GBP419m. FINANCIAL REVIEW Group Performance The unaudited results for the quarter and half year are summarised as follows: 3 months ended 6 months ended 6 months ended 3 months ended 2 October 3 months 2 October 2005 2 October 6 months 2 October 2005 2005 ended Business 2005 ended Business Re-measurement 2 October performance Re-measurement 2 October performance GBPm 2005 GBPm GBPm 2005 GBPm Total Total GBPm GBPm Group revenue 487 5 492 1,008 (29) 979 EBITDA 106 - 106 227 (32) 195 Operating profit/(loss) 58 - 58 135 (32) 103 Financing charges (9) - (9) (22) - (22) Profit/(loss) before tax 49 - 49 113 (32) 81 The discussion below focuses on the business performance results that are adjusted to reflect the results before exceptional charges and other movements arising from re-measurement. During the half year and quarter there were no exceptional charges. For the half year and quarter the re-measurement adjustments relate solely to the re-measurement impact of IAS 39. British Energy believes that this adjusted measure provides a better indication of underlying performance. Revenue Group revenue comprised generation sales, direct supply sales and miscellaneous income. Revenue was GBP1,008m for the half year and GBP487m for the quarter. Revenue reduced from the first quarter to the second quarter as a result of reduced output. The analysis of revenue is as follows: 3 months ended 6 months ended 2 October 2005 2 October 2005 GBPm GBPm Group revenue Wholesale generation sales 205 435 Direct supply sales net of energy supply costs 197 401 402 836 Energy supply costs recharged to customers 82 164 Miscellaneous income 3 8 Revenue 487 1,008 Wholesale generation sales includes revenue from Energy Purchases which cost GBP9m for the half year and GBP5m for the quarter. Output is analysed as follows: 3 months ended 6 months ended 2 October 2005 2 October 2005 TWh TWh Nuclear 14.9 30.6 Eggborough 0.8 2.5 Total 15.7 33.1 The realised price for the half year was GBP25.0/MWh and GBP25.3/MWh for the quarter. Operating Costs Operating costs were GBP873m for the half year and GBP429m for the quarter, as detailed below. 3 months ended 6 months ended 2 October 2005 2 October 2005 GBPm GBPm Fuel costs - nuclear 95 179 Fuel costs - fossil 16 69 Total fuel costs 111 248 Energy purchases 5 9 Materials and services 113 213 Staff costs 82 162 Depreciation 47 90 Amortisation 1 2 Other operating income (12) (15) Energy supply costs 82 164 NLF Cash Sweep payment - - Total operating costs 429 873 Total operating unit costs were GBP21.1/MWh for the half year and GBP21.8/MWh for the quarter. The component elements of the operating costs are discussed below. Fuel Costs Total fuel costs amounted to GBP248m for the half year and GBP111m for the quarter. Nuclear fuel costs were GBP179m for the half year and GBP95m for the quarter. The increase of GBP11m from the first quarter includes a GBP3m reduction as a result of reduced output in the quarter offset by a higher back end final core movement in provision of GBP14m. The value of back end final core costs is linked to the amount of fuel that remains unburned in reactors at the period end rather than being directly linked to the output of the period. Eggborough fuel costs for the half year were GBP69m and GBP16m for the quarter. The reduction from the first quarter reflects, in part, the reduced output at the station but is also due to the Eggborough fuel costs including costs attributable to carbon. Carbon costs are based on the market price of carbon at the period end and for the half year were GBP22m, comprising a credit of GBP2m for the quarter and costs of GBP24m for the first quarter. The market price of CO2 allowances have decreased in the quarter from approximately EUR25/tonne at 3 July 2005 to approximately EUR23/tonne at 2 October 2005. The cost of CO2 allowances impacts the marginal cost of coal and gas generation. 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. These costs were GBP213m during the half year and GBP113m during the quarter. The increase in costs from the first quarter were mainly due to additional investment expenditure incurred. Staff Costs Staff costs were GBP162m for the half year and GBP82m for the quarter and included pension costs of GBP28m and GBP14m respectively. Employer contributions to the pension scheme were GBP34m for the half year and GBP17m for the quarter reflecting the impact of increased contributions agreed as part of deficit repair and new salary sacrifice arrangements introduced from 1 April 2005. Other Operating Income The other operating income of GBP15m for the half year and GBP12m for the quarter relates to utilisation, excluding revalorisation, of the net commodity contracts provision, which was established on restructuring. NLF Cash Sweep Payment The NLF Cash Sweep percentage was 64.69% as at 2 October 2005, down from 64.99% at 31 March 2005 as a result of the exercise of a number of the Company's warrants. In accordance with the Group's accounting policy no accrual has been made for any potential future NLF Cash Sweep payment that may be payable based on the full year results. 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 Operating Profit The Group operating profit was GBP135m for the half year and GBP58m for the quarter. Financing Charges The total financing charges are analysed below: 3 months ended 6 months ended 2 October 2005 2 October 2005 GBPm GBPm Revalorisation of nuclear liabilities 52 119 Revalorisation of nuclear liabilities receivable and NLF receivable (52) (119) Revalorisation of fixed decommissioning obligation 2 6 Revalorisation of contracts provision 3 7 Total revalorisation 5 13 Net interest expense 6 13 Net credit to finance charge for pension liability (2) (4) Total financing charges 9 22 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 period. 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 half year and 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: IAS 39 Contract values provision Total GBPm GBPm GBPm As at 1 April 2005 34 238 272 Charge/(credit) to the income statement 32 (3) 29 Revalorisation - 4 4 Increase in hedge reserve through the statement of recognised income and expense 52 - 52 As at 3 July 2005 118 239 357 Credit to the income statement - (12) (12) Revalorisation - 3 3 Decrease in hedge reserve through the statement of recognised income and expense (2) - (2) As at 2 October 2005 116 230 346 Following the adoption of IAS 39 at 1 April 2005, the opening balance of GBP34m has risen by GBP82m to GBP116m. The effect on operating profit in the half year has been a reduction of GBP32m with the balance of GBP50m being recognised through the statement of recognised income and expense. The contract provision relates to contracts outside 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 decreased by GBP8m in the half year. 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 GBP36m before re-measurement and GBP46m after re-measurement in the half year and GBP20m before and after re-measurement for the quarter 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 GBP67m before re-measurement and GBP45m after re-measurement for the half year and GBP29m before and after re-measurement for the quarter. Earnings per Share (before Cash Sweep) There was an earnings per share of 11.9p for the half year and 5.1p 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 8.0p for the half year and 5.1p for the quarter. The diluted earnings per share for the half year was 11.5p before the effect of re-measurement and 7.7p after the effect of re-measurement and for the quarter was 5.0p before and after the effect of re-measurement. The conversion rights of the NLF Cash Sweep are not considered dilutive. Actuarial Loss on Pensions There has been one significant change in the actuarial assumptions adopted at 2 October 2005 compared with 31 March 2005 that mainly contributed to the actuarial loss on pensions of GBP89m for the half year 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. Cash Flow and Net Debt The operating cash inflow from operations was GBP150m for the half year. When adjusted for the increase in restricted cash, capital expenditure, the exercise of warrants and the costs associated with the sale of investments there was an increase in total cash of GBP113m. The net debt has therefore reduced from GBP220m at 31 March 2005 to GBP107m at 2 October 2005. Future Reporting On 24 October 2005, consent was received from the Group's bondholders to amend the US GAAP reporting requirements of the bonds. This allows the Company to cease reporting under US GAAP. As previously announced, the Company is taking steps to permit it to de-register from the United States Securities and Exchange Commission. The next set of quarterly results to be presented will be for the quarter ending 1 January 2006. Safe Harbour 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. 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.

Notes to the financial statements 1. Basis of Preparation These interim 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 IFRS, the Board of Directors has 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 interim 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 were included in the 'Results for the Quarter Ended 3 July 2005'. Notwithstanding this, the IFRS 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 interim results for the first six 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 six months the adjustments relate solely to the re-measurement under IAS 39. The definition of 'business performance' is given in the Non-GAAP Financial Matters section of this report. 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 three months and six months ended 2 October 2005 are unaudited but have been reviewed by the auditors and their report to the Company is set out below. These interim financial statements were approved by the Board of Directors on 13 December 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 months 6 months 15 January ended ended to 2 October 2 October 31 March 2005 2005 2005 TWh TWh TWh Output Nuclear power stations 14.9 30.6 14.3 Coal-fired power station 0.8 2.5 2.5 15.7 33.1 16.8 3 months 3 months 6 months 6 months ended ended 3 months ended ended 6 months 2 October 2 October ended 2 2 October 2 October ended 2 2 July 2005 2005 October 2005 2005 October 2004 to Business Re- 2005 Business Re- 2005 31 March performance measurement Total performance measurement Total 2005 GBPm GBPm GBPm GBPm GBPm GBPm GBPm Revenue Wholesale generation sales 205 5 210 435 (29) 406 250 Direct supply sales net of energy supply costs 197 - 197 401 - 401 170 402 5 407 836 (29) 807 420 Energy supply costs recharged to customers 82 - 82 164 - 164 73 Miscellaneous income 3 - 3 8 - 8 6 487 5 492 1,008 (29) 979 499 Wholesale generation sales includes revenue from Energy Purchases which cost GBP5m and GBP9m for the three and six months ended 2 October 2005 respectively (2004/05 GBP17m). 3. Net Revalorisation Charges 3 months 6 months 2 July 2004 ended ended to 2 October 2 October 31 March 2005 2005 2005 GBPm GBPm GBPm Revalorisation of nuclear liabilities - changes in price levels 21 56 23 - discharge of discount for period 31 63 27 Revalorisation of nuclear liabilities receivable (28) (66) (29) Revalorisation of NLF receivable (24) (53) (21) Revalorisation of contracts provision 3 7 2 Revalorisation of fixed decommissioning obligations 2 6 3 Net revalorisation charges 5 13 5 4. Taxation There is no current tax charge in the period due to the availability of trading losses carried forward. The charge for the three and six months of GBP20m and GBP36m before re-measurement and GBP20m and GBP46m after re-measurement respectively 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 566 million and 565 million ordinary shares in issue together with the dilutive potential of 17 million and 16 million ordinary shares in respect of warrants for the three and six months respectively. 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. 3 months 3 months 6 months 6 months ended ended ended 2 ended 2 2 October 2 October October October 31 March 31 March 2005 2005 2005 2005 2005 2005 Basic Diluted Basic Diluted Basic Diluted Net profit for the period (GBPm) 29 29 45 45 41 41 Weighted average share capital (number of shares, million) 566 583 565 581 561 579 6. Pension Costs There has been one significant change in the actuarial assumptions adopted at 2 October 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 2 October 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 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 25 November 2005, the Company announced that due to a number of recent equipment issues that have resulted in unplanned outages at the Company's power stations, the Company has revised its estimate of nuclear output for the financial year 2005/06. Based on current information, the Company expects that nuclear output for the financial year 2005/06 is unlikely to exceed 61 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, and this has since been confirmed in writing by the European Commission. Discussions with the Government are continuing but if this interpretation stands, it means that there could be a requirement to either modify the plant or materially restrict the operations of the two non-FGD units at Eggborough from 2008 in order to comply with the proposed emission limit values. INDEPENDENT REVIEW REPORT TO BRITISH ENERGY GROUP PLC Introduction We have been instructed by the company to review the financial information contained in the interim report 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 interim 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 interim 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 three months and six months ended 2 October 2005.

Restructuring Effective Date (RED) 14 January 2005. 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 The planned shutdown of nuclear reactors for regulatory inspection and maintenance.
