EDF has confirmed its intention to invest up to £1.1bn ($1.49bn) in the Sizewell C nuclear power project, subject to final agreements with the UK government and other investors.
The move will secure a 12.5% stake for EDF in Sizewell C and generate thousands of jobs across the UK.

The Sizewell C project aims to construct two European EPR technology reactors at an existing site, mirroring Hinkley Point C’s reactors, which are also backed by EDF.
Sizewell C will deliver clean electricity, create 10,000 jobs at peak construction and establish 1,500 apprenticeships through an extensive supply chain network.
EDF CEO Simone Rossi stated: “EDF’s intention to invest in Sizewell C is a further sign of its commitment to investing in Britain’s energy security and economic growth. It continues over 25 years of investment across the UK.
“EDF is proud to have restarted new nuclear in the UK, with Hinkley Point C paving the way for Sizewell C and constituting significant ongoing investment. As announced during the publication of the Group’s annual results in February, at the end of 2024 the total costs of Hinkley Point C amounted to €34.6bn.”

By GlobalDataThe UK government will retain a substantial stake in the project, securing oversight of its progress and minimising delays.
As part of its June 2025 spending review, the UK government announced a substantial £14.2bn funding injection into Sizewell C.
Bpifrance, France’s export credit agency, announced a £5bn debt guarantee for the project.
This facilitates lending from major commercial banks and is supported by Sizewell C’s innovative funding model, which distributes costs among consumers, taxpayers and private investors.
Urenco’s recent 15-year contract with EDF for fuel production for nuclear power plants further enhances UK-France energy cooperation.
UK Prime Minister Keir Starmer stated: “I’ve been clear there will be no more dithering and delay on Sizewell C – and this investment takes us a step closer to the benefits it will bring to the British people.
“Lower energy bills, thousands more jobs and apprenticeships, and better energy security – this is not only a vote of confidence in the UK as an investment destination, but also our Plan for Change in action.”
