The project was granted permission to build in July 2022. While preparatory works were started, obligations such as key road surveys and the establishment of governance groups had to be satisfied before construction could commence under its DCO. These requirements have been met and the formal construction phase can begin.

Sizewell C joint managing directors Julia Pyke and Nigel Cann said it was a significant moment for the project and a big step for British energy security.

“We’ve had a really successful year of pre-commencement works on site, and we’ve been working hard with local partners and organisations to ensure we’re ready to take this next step for the project,” they said.

“While Sizewell C will be a linchpin of Britain’s energy system, it’s much more than a power station, especially for this region. Entering the construction phase will be a game-changer for the area, helping to boost employment and skills, enhancing the local environment, and developing new clean technologies.”

In September last year, the government, Sizewell C and EDF launched an equity raise process to attract private investors to the project. While triggering the DCO and entering the construction phase is not dependent on a final investment decision, discussions with potential investors are continuing and a final investment decision is expected later this year.

Sizewell C will deliver 1,500 apprenticeships and support thousands of jobs across the country, with at least one-third of the peak construction workforce of 7,900 coming from the local area. The project will invest in local skills to ensure there is a pipeline of talent ready, not only to build and operate Sizewell C, but to support the UK’s future nuclear ambitions.
