Sizewell C has injected almost £1bn into the East of England economy after awarding contracts to local businesses, as the Suffolk-based nuclear project reaches two years since formal construction began.
The 3.2GW power station, expected to deliver around 70% of its construction value to UK companies, has committed to invest £4.4bn in the East of England over the course of its build. The project said it has already delivered around £3bn in contracts to more than 400 British suppliers.
The milestone follows what Sizewell C described as a strong second year, including its Final Investment Decision in summer 2025, which unlocked £38bn of funding and made it the first majority British-owned nuclear power station in over three decades.
The site workforce has expanded to nearly 2,000 people, including over 100 apprentices. Progress has also been made on offsite infrastructure works designed to reduce disruption, such as road improvements including new roundabouts at Yoxford and Friday Street on the A12.
Sizewell C also submitted a planning application for the College on the Coast, a post-16 education facility near Leiston intended to strengthen local skills and training. In community initiatives, the project announced the East Suffolk Trust (EaST), a £78m charity focused on biodiversity and landscape recovery, while the Sizewell C Community Fund has distributed £3m to local organisations during its first year.
On the Main Construction Area, works included installing sheet piles for the Temporary Sea Defence and constructing a bridge linking construction zones, reducing the number of trucks travelling through East Suffolk. The project also created three nature reserves near the site.
Looking ahead to 2026, Sizewell C expects further milestones including potential construction of the College on the Coast (subject to planning), completion of the A12 roundabouts, landscaping and tree planting, the arrival of first trains to site to cut road traffic, the launch of a new visitor centre, and the first environmental grants through EaST.
Nigel Cann, CEO of Sizewell C, said the project is delivering jobs, training and regional investment, while working with partners to minimise disruption during construction.
