National Grid take every care and precaution to ensure that information published on the Website or through the Services is accurate when posted and regularly updated, but we cannot be held liable for its accuracy or timeliness and we may change the information at any time without notice. You must not rely on information on the Website or accessed through the Services and you acknowledge that you must take appropriate steps to verify this information before acting upon it. No warranty or representation is made in respect of the timeliness or accuracy of any information sent to you by the updating service. We reserve the right to remove any information or material on the Website or accessible through the Services without warning, and without prejudice to any other accrued rights, and/or to make available such information or material when required to do so by law or when requested to by regulatory bodies or law enforcement organisations. You will remain responsible and liable for material you upload onto, or access from, the Website and/or Services, and you will indemnify National Grid, in the manner set out below in these Terms in relation to your accessing or uploading. 


We do not charge you a separate fee for access to and use of the Website or the Services. On this basis you agree that these Terms, and in particular the limits on National Grid's liability and obligations, are fair and reasonable. In the event that National Grid is found liable under these Terms, its total aggregate liability will be limited to £1,000. 

The information contained in the Website or accessed through the Services is not an invitation to invest in shares or other securities, or any other products or services or otherwise deal in these or enter into a contract with National Grid or any other company. The information provided should not be relied upon in connection with any investment decision. You should always seek appropriate professional advice in relation to such. 

The past performance of National Grid or any other company referred to on the Website or accessed through the Services cannot be relied upon as a guide to its future performance. The price of shares and the income derived from them can go down as well as up and investors may not recoup the amount originally invested. The Website and the information accessible through the Services contain 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. Because these forward-looking statements are subject to assumptions, risks and uncertainties, actual future results may differ materially from those expressed in or implied by such 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, 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, technological developments, the availability of new acquisition opportunities or the timing and success of future acquisition opportunities. Other factors that could cause actual results to differ materially from those published or otherwise available on or through the Website or Services may include the realisation of synergies from integration, the failure to retain key management, unseasonal weather impacting on demand for electricity and gas, 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 the National Grid's pension schemes and the regulatory treatment of pension costs and the impact of any potential separation and disposal by the National Grid group of any UK gas distribution network(s). For a more detailed description of these assumptions, risks and uncertainties, together with any other risk factors, please see National Grid's filings with the United States Securities and Exchange Commission (and in particular the 'Risk Factors' and 'Operating and Financial Review' sections in its most recent annual report on 20F). Recipients are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of their publication on the Website or being made accessible through the Services. National Grid does not undertake any obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date of their publication on the Website or being made accessible through the Services.

Any reference to any product or service (including the Services) which has been or may be provided by National Grid or any other company does not amount to a promise that such product or service will be available at any time. Changes to or improvements in such products or services may be made at any time without notice. 

We make no warranty whatsoever as to any goods or services purchased or obtained or offered to you by third parties through the Website and/or Services. Your dealings with any third parties, in particular advertisers and/or merchants, through the Website and/or Services, and any terms, conditions, warranties or representations with such third parties, are solely between you and such third party.

You agree not for yourself or through or by way of assistance to any third party to distribute, decompile, reverse engineer, disassemble or otherwise deal in or with the Website, the Services or materials therein or otherwise commercially exploit such material or content otherwise than as permitted by law. 


National Grid may terminate the Services, or restrict your access to them and the Website, refuse to sell/supply to or correspond with you, and/or remove your details from the relevant database without prejudice to any other accrued rights, without prior notice to you where: (i) there is a regulatory or statutory change limiting the ability to provide the Website and/or Services; (ii) any event beyond the reasonable control of National Grid occurs which prevents us from continuing the Services (for example, and without limitation, technical difficulties, capacity problems and communications failures); (iii) National Grid consider in our sole discretion that you are abusing the Website and/or Services or are otherwise acting in breach of these Terms. On termination, we may remove any material relating to you, if applicable, including e-mail addresses and shall have no obligation to forward any unread or unsent messages to you or third parties, on termination your user name and password may become available to others.

In particular you agree that any dealings you have with such third party site operators shall be on the terms and conditions (if any) of the third party operator (or as otherwise agreed by you and the third party operator). 


If any provision of these Terms, or any part of a provision of these Terms, is found to be illegal, invalid or unenforceable the remaining provisions, or the remainder of the provision concerned, shall continue in effect. A failure or delay by National Grid in enforcing compliance with any provision of these Terms shall not be a waiver of that or any other provision of these Terms. None of these Terms shall be enforceable under the Contracts (Rights of Third Parties) Act 1999 by any third party. You may not assign any of your rights or obligations under these Terms. The headings used in these Terms are for convenience only and shall not affect interpretation.
