1-3 Strand  London WC2N 5EH  www.nationalgrid.com          National Grid plc, Registered Office: 1-3 Strand, London WC2N 5EH.   Registered in England and Wales No. 4031152 1    20 July 2021    Tony Wood  Lydes Farm  Toddington  Gloucestershire  GL54 5DP    Appointment as Non-executive Director    Further to the approval by the Board of National Grid plc (the “Company”), and subject to agreement  of these terms and conditions by you, I am delighted to advise that your appointment as a Non- executive Director of the Company will be effective 1 September 2021.  This letter sets out the terms  of your appointment.  It is agreed that this is a contract for services and not a contract of employment.      Appointment    Your appointment, commencing on 1 September 2021, will be subject to your election by  shareholders at the Company's Annual General Meeting (“AGM”) in 2022, following which it is  expected that you will be subject to annual re-election by shareholders, unless your appointment is  otherwise terminated earlier in accordance with the Company's Articles of Association as amended  from time to time (the “Articles”) or by and at the discretion of either the Board or you upon 1 month’s  written notice.  Continuation of your contract of appointment is therefore contingent on satisfactory  performance and re-election by shareholders at forthcoming AGMs.      In the event that shareholders do not support your appointment or other shareholder action  terminates your appointment you will not be entitled to receive damages for breach of contract and  will not be entitled to any other compensation (or payment in lieu of notice).      Non-executive Directors are typically expected to serve one three-year term, and extended annually  thereafter, subject to the terms of this letter; any extension to this is subject to review by the  Nominations Committee (prior to making recommendations to the Board) having regard to the UK  Corporate Governance Code.    Time Commitment    Overall, we anticipate a time commitment of approximately 2-21/2 days on average per month, after  the induction phase, taking into account reading and preparation time for Board and Committee  meetings. This will include attendance at Board meetings (estimated 6 scheduled meetings per year)  plus strategy sessions, ad hoc and emergency meetings, Committee meetings, the AGM and any  general meetings. It is intended that certain Board meetings will be held at the Company's  operational sites (in the UK and US)).       The average time commitment stated above will increase should you become a committee member  or chair, or if you are given additional responsibilities, such as being appointed the Senior  Independent Director. Details of the expected increase in time commitment will be covered in any  relevant communication confirming the additional responsibility.

  National Grid plc, Registered Office: 1-3 Strand, London WC2N 5EH.   Registered in England and Wales No. 4031152 2    Following your induction, as a Non-executive Director you will also be expected to undertake at least  one site visit per year to the business, the location to be agreed with me or the Chief Executive.       In addition, you will be expected to devote appropriate preparation time ahead of each meeting and  such other time as is reasonably required to discharge your duties as a Director (for example if the  Company is involved in increased activity because it is involved in a major transaction).    If you are unable to attend a meeting, you should notify the Group General Counsel & Company  Secretary and prior to the meeting communicate your opinions and comments on the matters to be  considered to me or the relevant Committee chair so they can be taken into account at the meeting.    Role    All Directors, both Non-executive and Executive, have the same general legal responsibilities to the  Company. The Board as a whole is collectively responsible for debating and approving the strategic  direction of the Company and for promoting the success of the Company for the benefit of its  members by directing and supervising the Company's affairs.  All Directors must therefore take  decisions objectively in the interests of the Company, in compliance with their statutory and fiduciary  duties, and not do anything which is harmful to the Company or its business.      All Directors are expected to comply with the Company’s policies, procedures, rules and regulations  from time to time in force, including in particular, the Company’s Code of Ethics and its Share Dealing  Code.      The Board:   provides effective business leadership of the Company within a framework of prudent and  effective controls which enable risk to be assessed and managed;   sets the Company's strategic aims, ensures that the necessary financial and human  resources are in place for the Company to meet its objectives, and reviews management  performance; and   sets the Company's values and standards and ensures that its obligations to its  shareholders and others are understood and met.    In addition to these requirements of all Directors, the role of the Non-executive Director has the  following key elements:     Strategy: Non-executive Directors should constructively challenge and contribute to the  development of strategy;   Performance: Non-executive Directors should scrutinise the performance of management  in meeting agreed goals and objectives and monitor the reporting of performance;   Risk: Non-executive Directors should satisfy themselves that the financial function of the  Company is professionally managed and that financial controls and systems of risk  management are robust and defensible; and   People: Non-executive Directors are responsible for determining appropriate levels of  remuneration for Executive Directors and have a prime role in appointing, and where  necessary removing, senior management, and in succession planning.

NB: The Committee  membership fee does not currently apply to the People & Governance Committee. Subject to the  paragraph entitled ‘Termination’ below, in the event of termination of your appointment for any  reason, you will receive the fees paid pro rata through to your final date as a member of the Board.    These payments will be made monthly on or around 15th day of each month and will be pro-rated  from the date of your appointment.  You will not receive any further fees for membership of, or  attendance at, any ad hoc Board or Committee meetings.  If, for a reason related to illness, disability  or injury, you are unable to carry out your duties, payment of any fee(s) during any period of  incapacity will be at the discretion of the Board.     The Company will reimburse you, in accordance with the Articles and any expenses procedures  from time to time in force, for any reasonable expenses properly incurred in performing your duties.

  National Grid plc, Registered Office: 1-3 Strand, London WC2N 5EH.   Registered in England and Wales No. 4031152 4    It is accepted and acknowledged that you have business interests other than those of the Company.   As a condition to your appointment commencing, you are required to declare any such directorships,  appointments and interests in writing.     Unless specifically authorised to do so by the Board, you will not enter into any legal or other  commitment or contract on behalf of the Company.    In the event that you become aware of any potential conflicts of interest, these should be disclosed  to me and/or the Group General Counsel & Company Secretary as soon as apparent.  Where an  interest may give rise to a conflict of interest with the Company or any of its subsidiaries or associate  companies, the interest and potential conflict will need to be disclosed to the Board and its prior  consent obtained.    Additionally, if at any time you are considering acquiring any new business interest (including as  described in the letter to you regarding initial disclosures on appointment), you should raise the  matter initially with me and/or the Group General Counsel & Company Secretary; it will then go to  the Board for approval at the appropriate time (and after public announcement if deemed  appropriate).      Independent status    The Board has determined you to be independent according to the provisions of the UK Corporate  Governance Code.  As an independent Director it is important that you remain independent in  character and judgement.  If you become aware of anything that may affect, or could appear to  affect, this determination of independence, this should be disclosed to me and/or the Group General  Counsel & Company Secretary as soon as apparent.    Confidentiality    You will, naturally, during your appointment and following its termination not disclose or  communicate to any person (except as required by law or in the course of the proper performance  of your duties under this letter, or with the consent of the Board) nor use for your own account or  advantage any private or confidential information in any form whatsoever relating to the Company  or any of its subsidiaries or associate companies (“Confidential Information”) which you obtained  during your appointment or otherwise.  Additionally, you will use your best endeavours to prevent  the unauthorised use or disclosure of any such Confidential Information, other than as required by  law or regulatory authority.    This restriction will continue to apply after your appointment ends without limit in time but will not  apply to information which becomes public, unless through unauthorised disclosure by you. After  your appointment ends you will return all documents and information (whether written, visual or  electronic) under your control which belong to the Company.    Your attention is also drawn to the requirements under both legislation and regulation together with  Company policies and procedures as to the disclosure of ‘inside’ or ‘price sensitive’ information.   Consequently, you should avoid making any statements that might risk a breach of these  requirements without prior clearance from me or the Group General Counsel & Company Secretary.

  National Grid plc, Registered Office: 1-3 Strand, London WC2N 5EH.   Registered in England and Wales No. 4031152 9    Schedule 1  Guidance for Non-Executive Directors  (extracted from the July 2018 FRC Guidance on Board Effectiveness)    Non-executive directors should, on appointment, devote time to a comprehensive, formal and  tailored induction that should extend beyond the boardroom. Initiatives such as partnering a non- executive director with an executive board member may speed up the process of them acquiring an  understanding of the main areas of business activity, especially areas involving significant risk. They  should expect to visit operations and talk with managers and non-managerial members of the  workforce. A non-executive director should use these conversations to better understand the culture  of the organisation and the way things are done in practice, and to gain insight into the experience  and concerns of the workforce.    It is vital that non-executive directors have sufficient time available to discharge their responsibilities  effectively. The time commitment to engage with shareholders and other key stakeholders and get  to know the business can be considerable. It is advisable for non-executive directors to assess the  demands of their portfolios and other commitments carefully before accepting new appointments.  They should devote time to developing and refreshing their knowledge and skills to ensure that they  continue to make a positive contribution to the board and generate the respect  of the other directors.    Non-executive directors need to insist on receiving high-quality information sufficiently in advance  so that there can be thorough consideration of the issues prior to, and informed debate and  challenge at, board meetings. They should seek clarification or amplification from management  where they consider the information  provided is inadequate or lacks clarity.    Board papers and supporting information should:   be accurate, clear, comprehensive and up-to-date;   contain a summary of the contents of any paper; and   inform the director what is expected of them on that issue.    It is important that non-executive directors do not operate exclusively within the confines of the  boardroom but have a good understanding of the business and its relationships with significant  stakeholders. Accordingly, it is advisable for them to take opportunities to meet shareholders, key  customers and members of the workforce from all levels of the organisation.

If you become aware of anything that may affect, or could appear to  affect, this determination of independence, this should be disclosed to me and/or the Group General  Counsel & Company Secretary as soon as apparent.    Confidentiality    You will, naturally, during your appointment and following its termination not disclose or  communicate to any person (except as required by law or in the course of the proper performance  of your duties under this letter, or with the consent of the Board) nor use for your own account or  advantage any private or confidential information in any form whatsoever relating to the Company  or any of its subsidiaries or associate companies (“Confidential Information”) which you obtained  during your appointment or otherwise.  Additionally, you will use your best endeavours to prevent  the unauthorised use or disclosure of any such Confidential Information, other than as required by  law or regulatory authority.    This restriction will continue to apply after your appointment ends without limit in time but will not  apply to information which becomes public, unless through unauthorised disclosure by you. After  your appointment ends you will return all documents and information (whether written, visual or  electronic) under your control which belong to the Company.    Your attention is also drawn to the requirements under both legislation and regulation together with  Company policies and procedures as to the disclosure of ‘inside’ or ‘price sensitive’ information.   Consequently, you should avoid making any statements that might risk a breach of these  requirements without prior clearance from me or the Group General Counsel & Company Secretary.

  National Grid plc, Registered Office: 1-3 Strand, London WC2N 5EH.   Registered in England and Wales No. 4031152 9    Schedule 1  Guidance for Non-Executive Directors  (extracted from the July 2017 FRC Guidance on Board Effectiveness)    Non-executive directors should, on appointment, devote time to a comprehensive, formal and  tailored induction that should extend beyond the boardroom. Initiatives such as partnering a non- executive director with an executive board member may speed up the process of them acquiring an  understanding of the main areas of business activity, especially areas involving significant risk. They  should expect to visit operations and talk with managers and non-managerial members of the  workforce. A non-executive director should use these conversations to better understand the culture  of the organisation and the way things are done in practice, and to gain insight into the experience  and concerns of the workforce.    It is vital that non-executive directors have sufficient time available to discharge their responsibilities  effectively. The time commitment to engage with shareholders and other key stakeholders and get  to know the business can be considerable. It is advisable for non-executive directors to assess the  demands of their portfolios and other commitments carefully before accepting new appointments.  They should devote time to developing and refreshing their knowledge and skills to ensure that they  continue to make a positive contribution to the board and generate the respect  of the other directors.    Non-executive directors need to insist on receiving high-quality information sufficiently in advance  so that there can be thorough consideration of the issues prior to, and informed debate and  challenge at, board meetings. They should seek clarification or amplification from management  where they consider the information  provided is inadequate or lacks clarity.    Board papers and supporting information should:   be accurate, clear, comprehensive and up-to-date;   contain a summary of the contents of any paper; and   inform the director what is expected of them on that issue.    It is important that non-executive directors do not operate exclusively within the confines of the  boardroom but have a good understanding of the business and its relationships with significant  stakeholders. Accordingly, it is advisable for them to take opportunities to meet shareholders, key  customers and members of the workforce from all levels of the organisation.
