30 Second Briefing
Hull-based Modular Systems has been selected by McLaren Construction to manufacture prefabricated bathroom pods for the Sizewell C worker accommodation campus on the Suffolk coast, part of the new nuclear power station build. The contract will see Modular Systems expand its apprenticeship scheme with Hull College and recruit additional skilled staff across manufacturing, engineering, quality, logistics and technical design. Sizewell C has already invested nearly £5bn with more than 1,000 UK suppliers, signalling substantial ongoing demand for offsite and modular components in major nuclear infrastructure.
Technical Brief
- Pods are being supplied to McLaren Construction specifically for the Sizewell C Accommodation Campus build phase.
- Modular Systems is scaling manufacturing capability, implying increased line throughput and potentially multi-shift production for pod output.
- Expanded technical design roles suggest detailed coordination of pod structure, services penetrations and fire/acoustic performance with McLaren’s designs.
Our Take
McLaren Construction’s repeated selection on large UK schemes in our database – from Panattoni Park Swindon to Mountpark’s Hinckley logistics park – signals that EDF’s choice of delivery partners at Sizewell C is aligning with contractors already proven on fast-track, multi-building programmes.
McLaren’s recent use of FieldAI autonomous site-scanning robots on other UK projects points to a likelihood that digital progress verification and model-to-site deviation checks could be applied to the Sizewell C accommodation campus, which would help manage quality and schedule risk on a high-profile nuclear-adjacent build.
