EDF Energy has recruited Sir Alex Chisholm, formerly one of the most senior officials in Whitehall, as chairman of its UK business.

The French state-owned energy giant said Sir Alex will join next month after the Government’s Advisory Committee on Business Appointments gave the hire the green light.

He was previously permanent secretary at the Cabinet Office, meaning he was the most senior figures at the central government department aside from elected ministers.

Sir Alex said his appointment comes “at a time of great change and opportunity in the energy sector”.

“EDF continues to invest in nuclear, wind, solar and battery infrastructure to offer customers secure, clean and affordable electricity,” he said.

“I look forward to getting to know all parts of the company, and to helping EDF serve the needs and priorities of the UK.”

Britain’s UK’s energy suppliers have faced heavy criticism in recent years, after they booked outsized profits while customers’ household bills shot up in the wake of Russia’s invasion of Ukraine.

Meanwhile, EDF is also facing the potential of spiralling costs and delays on its Hinkley Point C nuclear plant, which is being built in Somerset.

The start of electricity production had been scheduled for June 2027 – but the completion date could now be up to three years later, it said earlier this year.

Simone Rossi, EDF’s UK boss, said: “Sir Alex brings great private and public-sector leadership, governance and regulatory experience that can help steer the company’s efforts to help Britain achieve net zero.”
