About the buyer

Nuclear Decommissioning Authority (NDA) is a non-departmental public body that oversees the clean-up of the UK's former nuclear sites, sponsored by the Department for Energy Security and Net Zero. Suppliers register and bid through OneNDA, its eCommercial portal. Contract awards above a set value are published on Find a Tender, and framework agreements route further work through government procurement hubs. Four group companies, including Sellafield and Nuclear Restoration Services, deliver its site programmes. Meet the Buyer events connect suppliers with upcoming opportunities across the group. The authority has set a target for 9% direct spend with SMEs by 2027/28.

Procurement spend from central entities makes up 66% of overall UK public spend.

Over the past 5 years, most of NDA's contract awards have been in research and development, business services and IT services.
