Additional Information
Join the team at Sizewell C. The power of good for Britain.
It’s not every day you get the opportunity to shape the working culture of what will be one of Europe’s largest construction projects, while also helping Britain to reach its target of Net Zero emissions by 2050. That’s one of the reasons Sizewell C will be unlike anything you’ve ever experienced before, and you’ll need to be an exceptional professional to reach the high standards this critical infrastructure project demands.
The UK is experiencing a nuclear renaissance and Sizewell C – along with its sister project at Hinkley Point C in Somerset – is powering the change. We’re ramping up at pace as we look ahead to the Financial Investment Decision in early 2025, and the start of construction soon after. With government fully on board and public opinion shifting significantly in favour of nuclear, there’s never been a better time to join our project.
