Summary of the contracting process

UK Atomic Energy Authority commissioned replacement of the roof on its D8 building at Culham Campus in Oxfordshire. The work is roofing construction: removing the existing roof and installing a replacement. This site-specific project sits alongside LHC Procurement Group’s wider roofing framework, which covers traditional flat, liquid-applied flat, profiled metal, pitched and mixed roofing. Framework workstreams include roof surveys, design, refurbishment and replacement, repairs, insulation and vapour barriers, roof lights, rainwater goods, fascias, soffits and renewable-energy installations where required. The framework covers projects across England, while the D8 replacement is located at Culham. LHC Procurement Group arranged the framework; the UK Atomic Energy Authority is the buyer for the D8 roof replacement.

The D8 roof replacement has been awarded to CWG Group Ltd, and its contract was signed on 23 October 2026. The contract value is £120,000. This is one project under a wider roofing framework procured by LHC Procurement Group through a restricted procedure. The five framework workstreams cover traditional flat, liquid flat, profiled metal, pitched and mixed roofing. Each has a recorded contract value of £165 million, and the framework contracts were signed on 14 October 2025; the stated contract duration for each is 1,440 days. The framework evaluation weighted general technical capability at 30%, workstream-specific technical capability at 20%, regional capability at 20%, rates at 20%, and overheads and profit at 10%. Supplier selection required NFRC membership. The D8 award is specifically for traditional flat roofing.

The framework demonstrates demand for both individual roof-replacement projects and a broad range of planned roofing work. Suppliers seeking to compete for similar requirements from these buyers would need NFRC membership and demonstrable general roofing capability, alongside expertise suited to the relevant workstream. For flat-roof projects, this includes replacement and installation; other framework scopes call for specialist skills in liquid-applied systems, profiled metal, pitched roofs or mixed systems. The wider requirements include surveys, design, repairs, structural and drainage considerations, insulation, waterproofing and associated roof components. Renewable-energy integration, including solar installations, is part of some workstreams. Regional delivery capacity also mattered in evaluation, as did competitive rates and overheads and profit. The appointed framework suppliers include many roofing businesses, largely SMEs, indicating that capable specialist firms as well as larger contractors competed successfully.
