About the buyer

Nuclear Restoration Services Limited decommissions 14 former nuclear sites, from Sizewell A to Trawsfynydd. The Nuclear Decommissioning Authority owns the company and sets its group-wide commercial strategy. New tenders above the routine threshold are advertised on the Find a Tender service. Suppliers register and bid through the wider NDA group's shared eProcurement system. The company also runs its own framework agreements, covering scaffolding, lifting and characterisation services at its sites. Bidders for classified decommissioning work must also pass security clearance checks. A dedicated supply chain team handles questions and comments from prospective suppliers.

£434bn was the total UK public sector procurement spend in FY 2025/26.

Over the past 5 years, most of Nuclear Restoration Services Limited's contract awards have been in architectural and engineering services, construction work and business services.
