The Gas and Electricity Markets Board today announced that Chief Executive Officer Jonathan Brearley will be stepping down from his role at the end of March to take up the position of Permanent Secretary at the Department for Energy Security and Net Zero.

During Jonathan’s tenure, Ofgem navigated a period of significant transformation.

Under Jonathan’s leadership, the organisation stabilised the energy market and protected consumers during the gas crisis, reformed the financial resilience of the retail sector, and saw consumer satisfaction rise from record lows to record highs.

Jonathan drove progress towards the government’s clean power ambitions, with notable achievements which include innovative regulatory reforms to infrastructure, the Accelerated Strategic Transmission Investment initiative, a major grid overhaul, and the creation of NESO.

Through both the Covid pandemic and the gas crisis, Ofgem, guided by Jonathan, demonstrated remarkable resilience and tenacity, building essential skills and capabilities during unprecedented times.

Mark McAllister, GEMA and OFGEM Chair said:

“On behalf of the Board, I want to thank Jonathan for his immense dedication and service. While we are sad to see him go, we are proud that the CEO of Ofgem has been chosen for such a pivotal role in government.

“We wish Jonathan the very best in this next chapter and look forward to continuing to work together as we deliver a successful energy transition for consumers.”

The Board will initiate a formal search process to appoint a permanent successor. In the interim, Tim Jarvis, currently the Director General for Markets, will serve as Acting CEO, ensuring continuity and stability during the transition period.

Jonathan Brearley, outgoing CEO, Ofgem 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.”

Ofgem remains well-placed to drive ongoing change and deliver value for consumers. The Board is committed to a smooth transition and to supporting leadership as the organisation continues its critical work.
