Please let us know if you'd like to discuss flexible working arrangements by highlighting this on your application.

Sizewell C Limited (Sizewell C) is nuclear site licensed company whose business is to design, finance, construct, commission, operate, maintain, and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk.  Sizewell C was formerly under the majority ownership of the EDF Group but is currently majority owned by HM Government and operates as an independent company. EDF remains a key shareholder in Sizewell C and the business therefore maintains close links to EDF as a part of its 'nuclear family'.

 As a Sizewell C employee, you may wonder why you are contacted by colleagues with an EDF email, or see the EDF logo on portals that you access and/or documentation you receive; this is because we have partnered with EDF for the provision of a number of support services whilst we complete a successful transition out of the EDF group.

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.
