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.
