EDF to invest in Sizewell C, while nuclear decommissioning consultation opens
The UK Government will remain a significant shareholder in Sizewell C.
The French energy firm will take a 12.5% stake in the UK's Sizewell C nuclear plant.
The move follows £14.2bln of funding from the UK Government last month.
At peak construction, Sizewell C will reportedly support 10,000 jobs, and thousands more in the nationwide supply chain, and create 1,500 apprenticeships.
Bpifrance, France’s export credit agency, is set to provide a £5bln debt guarantee to the power station.
UK company Urenco has also signed a 15-year deal with EDF to produce fuel for nuclear power stations.
While French engineering company Assystem has announced plans to double its nuclear workforce in the UK.
Further investors and details on the project’s financing will be confirmed at the point of the Final Investment Decision, targeted for this summer.
Prime Minister Keir Starmer says, ‘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.’
The announcement comes as the UK's Nuclear Decommissioning Authority (NDA) calls for engagement on a refreshed decommissioning strategy.
The NDA has published its strategy for consultation, setting out the roadmap to decommission the UK’s earliest nuclear sites safely, securely and sustainably.
In its draft strategy, the NDA reaffirms its highest strategic priority is hazard reduction at Sellafield, which is focused on the safe retrieval of waste from the site’s legacy ponds and silos, the most complex challenges in the clean-up mission.
The draft strategy also marks a shift towards greater integration and collaboration across the NDA group to strengthen efforts to address the UK’s nuclear legacy.
The public consultation is open for 12 weeks until 29 September 2025.
The final strategy will be submitted for approval to the UK and Scottish Governments, ahead of final publication in March 2026.
