His father served in the Royal Navy before becoming a chartered surveyor, a background that instilled in him values of service, discipline, and adaptability. He attended Gillingham School in Dorset, a comprehensive school that played a role in shaping his early outlook. These formative years exposed him to a mix of discipline and community responsibility, traits that would later define his leadership approach.
He pursued higher education with determination. At the University of Glasgow, he studied Mathematics and Physics, subjects that trained him in analytical problem-solving. Later, he earned an MPhil in Economics from the University of Cambridge, equipping him with both technical and economic expertise. This combination of science and economics became vital for his future roles in energy policy and regulation.
Start of Career in Civil Service
Jonathan Brearley began his professional journey within the Strategy Unit at 10 Downing Street, serving under Prime Minister Tony Blair between 2002 and 2006. This experience gave him early exposure to policymaking at the highest level. His role involved strategic analysis and designing policy frameworks, building his reputation as a reliable and skilled civil servant.
Later, he joined the Department for Environment, Food and Rural Affairs (DEFRA) under David Miliband. Here, he was instrumental in establishing the Office of Climate Change, which played a critical role in shaping early climate policy. This step marked his shift towards energy and climate-related responsibilities, positioning him as a specialist in the sector.
Career at the Department of Energy and Climate Change (DECC)

In this role, Brearley led the landmark Electricity Market Reform, a project designed to ensure reliable and affordable energy while transitioning towards low-carbon solutions. This experience provided him with deep insight into how complex reforms are managed, balancing competing demands from industry, government, and consumers.
The DECC years allowed him to work closely with technical experts, policymakers, and international partners. His growing expertise made him a valuable asset to the UK’s long-term energy strategy.
Consultancy and Private Ventures
After leaving the civil service, Jonathan Brearley established a consultancy focusing on energy-sector strategy and regulatory issues. His consultancy work extended beyond the UK, including advisory projects in India, where energy market reforms were being explored. This phase expanded his global perspective and allowed him to appreciate the diverse challenges faced by different economies in achieving secure and sustainable energy supply.
His consulting years gave him a more entrepreneurial edge, diversifying his experience before returning to a leadership role in the public sector.
