Mr Pibworth, currently SSE’s chief commercial officer and a board member since 2017, will formally assume the CEO role after the company’s annual general meeting (AGM) on 17 July 2025. He joined SSE in 1998 and has held key commercial roles, overseeing renewables, thermal generation, energy markets, and customer solutions. His experience in energy markets and large projects was central to SSE’s strategy.

Welcoming the appointment, SSE Chair Sir John Manzoni said: “Martin is a proven industry leader, with deep sector experience and a highly strategic outlook, demonstrating all of the attributes needed to be a successful chief executive at this hugely exciting time for the company.

“The board concluded that Martin was the outstanding candidate in a very competitive process and I look forward to supporting him as he leads SSE through the next phase of development and growth.

“Alistair has been an exceptional chief executive, leading the company’s transition into being the UK and Ireland’s clean energy champion, whilst delivering true and lasting value for all of our stakeholders. As well as his legacy at SSE, his support in ensuring a smooth handover of responsibilities continues to be greatly appreciated.”

Mr Pibworth said: “I’m excited to be leading SSE as the Company embarks on its next stage of evolution and growth.

“As an integrated electricity group focused on the energy transition, we are well-placed for long-term growth from our established positions in networks, renewables and flexibility. In our highly dynamic operating environment, we have the capabilities and portfolio to manage complexity and volatility, whilst pivoting towards value as it emerges.

“I look forward to continuing to work with governments, shareholders and other stakeholders on powering society’s needs whilst creating sustainable value as we electrify the economy.”

Mr Phillips-Davies will continue as CEO until the July 2025 AGM, stepping down from the board at that point before leaving SSE in November 2025. He will remain non-executive chair of SSEN Distribution during this period. The succession process was overseen by Sir John Manzoni and the nomination committee, supported by external recruiters.

Subject to shareholder approval, Mr Pibworth’s initial base salary will be £970,000 per annum from July 2025, rising to £1,050,000 in April 2026, alongside other benefits and incentive plans aligned with the company’s remuneration policy.
