The UK government has signed an agreement worth over £38 billion with a number of backers, including EDF and Centrica , for construction of the 3.2 GW Sizewell C nuclear power project on the Suffolk coast.

The UK government had a 84 per cent stake at the end of 2024, with EDF holding a 16 per cent stake. Under this final agreement, the UK government will remain the projects largest stakeholder, but with its stake sharply reduced to 44.9 per cent, while EDF’s share will fall to 12.5 per cent. Centrica will take a 15 per cent share, and the Canadian investment group La Caisse 20 per cent. Investment manager Amber Infrastructure will take a 7.6 per cent share.

Rachel Reeves, Chancellor of the UK, said: “The investment was a powerful endorsement of the UK as the best place to do business and as a global hub for nuclear energy. Delivering next-generation, publicly owned clean power is vital to our energy security and growth, which is why we backed Sizewell C.”
