Cautionary statement Unless otherwise stated, all financial data of National Grid contained in this presentation is as reported under IFRS.This presentation contains certain statements that are neither reported financial results nor other historical information. These statements are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements include information with respect to National Grid s financial condition, National Grid s results of operations and businesses, strategy, plans and objectives. Words such as anticipates, expects, intends, plans, believes, seeks, estimates, may, will, continue, project and similar expressions, as well as statements in the future tense, identify forward-looking statements. These forward-looking statements are not guarantees of National Grid s future performance and are subject to assumptions, risks and uncertainties that could cause actual future results to differ materially from those expressed in or implied by such forward-looking statements. Many of these assumptions, risks and uncertainties relate to factors that are beyond National Grid s ability to control or estimate precisely, such as delays in obtaining, or adverse conditions contained in, regulatory approvals and contractual consents, unseasonable weather affecting the demand for electricity and gas, competition and industry restructuring, changes in economic conditions, currency fluctuations, changes in interest and tax rates, changes in energy market prices, changes in historical weather patterns, changes in laws, regulations or regulatory policies, developments in legal or public policy doctrines, the impact of changes to accounting standards and technological developments. Other factors that could cause actual results to differ materially from those described in this presentation include the ability to integrate the businesses relating to announced or recently completed acquisitions with National Grid s existing business to realise the expected synergies from such integration, the availability of new acquisition opportunities and the timing and success of future acquisition opportunities, the timing and success or other impact of the sales of National Grid s non-core businesses, the failure for any reason to achieve reductions in costs or to achieve operational efficiencies, the failure to retain key management, the behaviour of UK electricity market participants on system balancing, the timing of amendments in prices to shippers in the UK gas market, the performance of National Grid s pension schemes and the regulatory treatment of pension costs, and any adverse consequences arising from outages on or otherwise affecting energy networks, including gas pipelines owned or operated by National Grid. For a more detailed description of some of these assumptions, risks and uncertainties, together with any other risk factors, please see National Grid s filings with and submissions to the US Securities and Exchange Commission (the SEC ) (and in particular the "Risk Factors" and "Operating and Financial Review" sections in its most recent Annual Report on Form 20-F). Except as may be required by law or regulation, National Grid undertakes no obligation to update any of its forward-looking statements. The effects of these factors are difficult to predict. New factors emerge from time to time and National Grid cannot assess the potential impact of any such factor on its activities or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. 2

IFRS technical details This presentation is based on continuing business performance, so it excludes exceptional items and remeasurements. These remeasurements relate to movements in the carrying value of financial instruments and of commodity contracts. They arise from changes in mark-to-market values or exchange rates and are reflected in the income statement to the extent that hedge accounting is not achieved or is not fully effective. Further details can be found in Note 3 of National Grid s 2007/08 Full Year Results report at www.nationalgrid.com 35
