British business - the backbone of our supply chain

Thousands of companies across the UK are set to benefit from Sizewell C. 

It is expected that 70% of the project’s construction value will be spent with UK-based businesses.

Sizewell C will help to “level up” the country with huge opportunities for East Anglia and other regions.

Sizewell C and procurement

Since the government announced its support for Sizewell C, we have started to secure a range of goods, works and services required to build and operate our power station. 

Because we are building a near replica of Hinkley Point C, we will be using many of the supply chain companies and services they do, while creating brand new opportunities for businesses in the East of England. 

By replicating the design of Hinkley Point C, we can reduce costs and construction risks and deliver more value to UK consumers.  

The goods, works and services we will need at Sizewell C include, but are not restricted to, the categories below.

"The legacy that could be left behind is huge!"

Sizewell C will bring thousands of jobs and training opportunities to East Suffolk. In this video, we hear from Brafe Engineering in Woodbridge, Suffolk, about what a new power station means to them.

Supplying nuclear projects

Sizewell C will be modelled on Hinkely Point C (HPC), the nuclear power station EDF is building in Somerset. Watch this video to hear tips from HPC suppliers about working for us.
