  • Sizewell C currently has nearly 300 active UK suppliers – with a contract value of £2.5bn  
  • Suffolk-based project delivered over £100m in local contracts in first year of construction 
  • Key project milestones achieved in first twelve months, including Nuclear Site Licence
  • £250m local benefits package activated in first year, with benefits across East of England  

Sizewell C is already delivering £2.5bn in contracts to nearly 300 UK suppliers, the project announced today as it marked its first year of construction on the Suffolk coast.    

The 3.2GW nuclear power project – which will deliver 70% of its construction value to UK companies and support 70,000 high-quality jobs across the UK – is committed to spending £4.4bn in the East of England alone across the construction period. In its first year of construction, the Suffolk-based project surpassed £100m in local contracts.  

The contracts milestone caps a hugely successful first year of construction for Sizewell C. The project has made significant progress across its main development site, including archaeology and earthworks, as well as the preparatory work for its concrete batching plant and temporary desalination plant.   

It completed new site offices on its Ancillary Construction Area (ACA), as well as delivering enhancements to local road and rail infrastructure, and beginning work on its park and ride sites. 

In its first year of construction, the project secured its Nuclear Site Licence in April, agreed one of the largest letting transactions in the UK for storage and logistics, and signed agreements for best in class conditions for its workers. 

Julia Pyke and Nigel Cann, Joint Managing Directors of Sizewell C, said: “It’s been an incredible first year of construction for Sizewell C. We’ve now got around 1,000 people driving this project forward both on our main development site and off-site infrastructure, and we’ll have around 2000 people by the end of the year with around double the amount of apprentices.  

“We’re making big gains with early manufacturing, with equipment already 20% through manufacture. That means we’re already able to deliver significant contract value to suppliers and drive growth right here in the UK. 

“Building on the work of Hinkley Point C, we have a fixed design and a capable and industrialized supply chain in place, and that gives us a big advantage when it comes to cost certainty and clarity of schedule. A year down the line of formal construction, we’re in a very strong position to deliver a project that will provide lower bills and clean energy to six million homes, thousands of good jobs, and energy security for Britain.” 

Sizewell C has signed multiple contracts with businesses across Suffolk, covering everything from construction and aggregates to building supplies and energy systems. Today it announced further regional contracts including a £19m contract for Ipswich-based business, Jackson Civil Engineering, to deliver key road schemes early in 2025.
