About Sizewell C

Our vision is to Lead the Way on Nuclear. We understand the organisation, collaboration and imagination needed to build a nuclear power station.  We want to show what good leadership for the nuclear industry and British infrastructure looks like.

We aim to set an example for future infrastructure projects by maximising the benefits to communities, locally, regionally and nationally.

We want this to be a project Britain can be proud of – providing value to the country for the rest of the century.

A Pioneering, Integrated and Socially Responsible Approach

We have four strategic aims which serve as source of inspiration and direction, shaping our company strategy, guiding decision-making and providing a roadmap of success to deliver our vision.

Attract

Attract, support and nurture outstanding talent and expertise in our people, and develop a centre of excellence for the nuclear industry in the UK.

Build & Operate

Set the model for the building and operation of a power station – on time, on budget and with relentless focus on quality, safety and the environment.

Invest

Develop genuine partnerships with our neighbours, suppliers and investors to create lasting economic and social value, pioneering a new integrated approach to building infrastructure in the UK.

Promote

Ensure that the social, economic, environmental and energy security benefits of our work and of the wider nuclear industry are more widely understood and celebrated nationally.

Company Values

Our company values guide us through everything we do and how we deliver against our vision and strategic aims.

Safety and Quality First

The safety of our employees, suppliers, and the public is of upmost importance. All our activities, whether on site, in our offices or the transportation of materials, must be carried out to the highest standards. This is why we will always put safety and quality first.
