CECA: Sizewell C Investment A ‘Significant Boost’ For UK Economy

Civils contractors have welcomed today’s final investment decision on a new nuclear power station at Sizewell C, describing it as a major milestone for the UK’s infrastructure and a significant boost for the UK economy.

The Government’s decision paves the way for construction to move ahead on the £38 billion project, which is expected to support up to 10,000 jobs and create 1,500 apprenticeships during peak construction.

With 70 per cent of the value of contracts expected to benefit UK businesses, and a strong focus on engaging local supply chains in the East of England, the project offers a once-in-a-generation opportunity to strengthen regional economies and build capacity within the civil engineering workforce.

CECA also welcomed the adoption of the Regulated Asset Base funding model, which provides a more sustainable and affordable financing structure compared to previous approaches. This model is expected to deliver significant savings to consumers and investors alike, while giving contractors greater certainty and confidence to plan for the long term.

Commenting, spokesperson for the Civil Engineering Contractors Association (CECA) and Executive Director of CECA Southern David Allen said: “This is a defining moment for the UK’s civil engineering sector. It reinforces the central role of nuclear power in delivering a clean, secure and reliable energy future, while unlocking long-term opportunities for our members and the wider construction industry.

“The focus on apprenticeships, skills development and UK supply chain engagement is particularly welcome, and we look forward to seeing the benefits of this investment ripple through communities across the country.

“CECA has long argued that new nuclear power is a vital component of the mixed portfolio of electricity generation the UK needs.

“It is vital that industry, Government, and all stakeholders now work together to maintain momentum in ensuring Sizewell C’s successful delivery, so that the project sets a benchmark for sustainability, productivity, and social value.

“Our members are ready to deliver this nationally-significant infrastructure project which will be foundational not only to keeping the lights on and achieving a net zero future, but will create high-skilled, high-paying jobs, and provide a substantial boost for the whole UK economy.”
