The extra money from allocated funds will help prepare the site for construction, procure key components from the project’s supply chain and expand its workforce.

Activity will ramp up at the Suffolk site supporting continued preparation works including constructing onsite training facilities for 1500 apprenticeships, further development of the plant’s engineering design and direct investments in the local community ahead of work starting.

Minister for Nuclear and Networks Andrew Bowie said: “Sizewell C will be a significant part of the revival of nuclear energy in this country – providing clean, home-grown power to millions of homes, providing thousands of jobs and ending reliance on foreign electricity to bolster our energy security.

“Today’s funding announcement is a clear demonstration of the government’s commitment to this vital project, and will mean the site will be shovel-ready, and work able to start, much more quickly.”

The cash follows a £170m tranche of site preparation cash announced earlier this summer.

Sizewell C Company Joint Managing Director, Julia Pyke, said: “This is great news and puts us in an even stronger position to start full construction. It will also allow us to implement several community schemes over the next few months.

“We want people living near Sizewell C to see the benefits of the project as soon as possible and we’re looking forward to getting started on a range of proposals which will bring real improvements to the area well before the main construction gets underway.”
