Board Change

National Grid plc today announces that Edward Astle, Executive Director responsible for Non-Regulated Businesses and Business Development, will be leaving the Company on 30 April 2008. His responsibilities for the remaining Non-Regulated Businesses will be reallocated across the existing management team.

Edward joined the Board of National Grid originally as Group Director, Telecommunications in September 2001.

Steve Holliday, Chief Executive of National Grid, paid tribute to Edward’s contribution to the Company: “Edward has been a key member of the executive team. He has helped to reshape our business, created real value and recently successfully disposed of many of our non-core businesses. I want to personally thank him and all of us wish him well for the future”.

Edward Astle said: “Since joining National Grid I have seen the company grow into one of the largest investor-owned energy companies in the world, with a balanced spread of businesses on both sides of the Atlantic. It has given me great satisfaction to be part of this development. The company has great prospects and I wish Steve and the team every success as they drive the business forward”.

The Chairman, Sir John Parker, said “The Board had valued Edward’s contribution over the past 6 ¹/2 years and in particular the over £3b of value crystallised by selling the majority of Non-Regulated Businesses during the past year.”
