Frequently Asked Questions

Why should I register?


The Sizewell C Supply Chain database will be used to match the requirements of Tier 1 contractors involved in the prospective construction of Sizewell C with suitably skilled local and regional companies.

The main works at Sizewell C will be delivered via approximately 150 major contracts to ‘Tier 1’ contractors, who will need to find their own suppliers. They are encouraged to include local suppliers, which can be facilitated through registration on www.sizewellcsupplychain.co.uk.

My company is based in the East of England but not within Suffolk. Can I register?


Yes, the Sizewell C Supply Chain is the main point of contact for businesses in Suffolk, Norfolk, Cambridgeshire, Bedfordshire, Hertfordshire, and Essex wishing to engage in the Sizewell C project.

If you are outside these areas, we recommend registering on EDF’s nuclear new build supplier portal:

Does Sizewell C exclude suppliers from outside local and regional areas?


The supplier matching process will prioritise local and regional suppliers. If required capabilities are not found in these areas, the search will broaden.

Do I register as a Direct or Indirect Supplier?

Direct – Site Contractor: For businesses directly involved in construction on-site. Financial information and quality management standards are required.

Indirect – Services Supplier: For businesses providing off-site services such as taxis, accommodation, or office supplies. Less information is required for this category.

What happens after I register?


Your submission will be assessed as:

‘Incomplete’ – Important data is missing.

‘Almost Complete’ – Most data is submitted but some clarification is required.

What support is available to achieve 'Ready' status?
