The deal will see over 500 tonnes of steel fabricated at the company’s Scarborough plant in North Yorkshire before erection of a two-storey frame on the Suffolk coast.

The amenity building will form the hub of Sizewell C’s worker accommodation campus, supporting thousands of out-of-area staff during the decade-long build.

William Hare brings more than 50 years of nuclear sector experience to the job, having worked extensively on Hinkley Point C since 2019.

Fabrication work will start in October, with on-site installation expected before the end of 2025.

Sizewell C joint managing director Nigel Cann said awarding the contract to a UK steel business was part of a pledge to ensure 70% of construction spend stays with domestic firms. “This is also great news for the North of England, where we’ve already committed to investing £2.5bn during the construction of our project.”

The Scarborough facility – home to the UK’s first fabrication robot – will deliver the bulk of the framework on a fast-track schedule.

The latest contract award follows a construction management agreement with McLaren Construction will deliver the 2,400-bed campus for site workers, hailed as setting new standards in site accommodation.

The scheme will see 16 residential blocks of three and four storeys built to house the incoming workforce.

Each building will contain single-occupancy living units, each with its own ensuite, kitchenette, wardrobe, desk and TV.

Every floor will house around 40 rooms accessed via a central corridor, with shared services cupboards providing hot water, power and waste distribution. Eight accessible rooms will be included in each three-storey block.
