The head of Ofgem is stepping down from his role at the end of the month, the energy watchdog has announced.
Chief executive Jonathan Brearley is taking on the post of permanent secretary at the Department for Energy Security and Net Zero.
Tim Jarvis, the current director general for markets, will serve as acting CEO until a successor is appointed.
Mr Brearley said: “It has been a privilege to lead Ofgem and work alongside such a talented group of public servants. I am proud of all that we have achieved together.
“I am confident that Ofgem is in excellent hands with Tim alongside the wider executive committee and well-positioned to continue delivering on its mission to protect energy consumers now and into the future, as we advance through the energy transition.”
Energy Secretary Ed Miliband praised Mr Brearley as a “deeply experienced, dedicated and imaginative public servant”.
“As we continue to deliver our clean energy mission to bring down energy bills for families and take back control of our energy with clean, homegrown power, I am delighted to welcome Jonathan to lead the department,” he said.
Cabinet Secretary Dame Antonia Romeo said: “Jonathan brings a wealth of energy experience from within the Civil Service and beyond. I’m delighted to welcome him to the Department for Energy Security and Net Zero, and to the Permanent Secretary team.
“I look forward to working with Jonathan and the team at DESNZ as they deliver the Government’s agenda on energy security and clean power.”
Mr Brearley, the chief executive of Ofgem since February 2020, earns over £300,000 annually.
Prior to his current role, he served as the energy regulator's executive director for systems and networks. His career also includes running a consultancy, where he worked on energy industry projects, including market reforms in India.
Before joining Ofgem, Brearley held significant roles within the UK civil service. He was director of electricity markets and networks at the Department of Energy and Climate Change.
Earlier, at the Department for Environment, Food and Rural Affairs, he was tasked by David Miliband with setting up the Office of Climate Change.
His public service began in 2002, working in Prime Minister Tony Blair’s strategy unit at 10 Downing Street until 2006.
