Sizewell C's business is to design, finance, construct, commission, operate, maintain, and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk. Overall, whilst the Company is in the construction phase, the Boards' principal focus is on the development and construction of Sizewell C on time, on budget and to the highest quality and safety standards. The Company is maturing to meet all these requirements.
Sizewell C is economically regulated by OFGEM under the Regulated Asset Base (RAB) model similar to other UK electricity distribution networks and Thames Tideway.
Sizewell C construction strategy is to replicate the design of Hinkley Point C, using the majority of the same supply chain, but innovating in the way it is delivered to achieve savings in time and cost of around 20%. The CCO will need to be guided by and incorporate lessons learned from the Hinkley Point C commercial delivery to achieve Sizewell C's ambition.
Following Financial Completion and Revenue Commencement, Sizewell C is fully funded and is owned by the Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.

If this sounds like the next step in your career, we'd love to hear from you.
When joining Sizewell C, 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.
At Sizewell C we encourage and embrace diversity and how it can improve our experience and performance at work. It is a requirement that those who join us have the right to work in the UK. Whilst sponsorship may be a possibility that we can explore, we are fully committed to local recruitment where possible, and those already holding the right to work in the UK.
To be appointed to this role, you will need to meet the criteria for Security Vetting, which will, ordinarily, require you to have been a resident of the UK for at least three of the past five years.
