Contractors Working on the Hinkley Point C Nuclear Project

NNB the developer of the Hinkley Point C project is acting as the programme manager splitting the scope into equipment supply and construction contracts, with direct responsibility for project and integration management.

NNB will contract directly with Tier 1 companies who generally subcontract to Tier 2 suppliers who in turn may contract with Tier 3 and 4 companies. NNB’s procurement strategy involved early engagement with the supply chain, selecting preferred contractors with some Tier 1 contractors having been involved on the HPC project for over 6 years prior to receiving a formal contract for their package of the works.

There is a rolling programme of contractor award, mobilisation and delivery with almost £9bn of contracts having been awarded by the end of 2017.
