About the buyer

Sellafield Limited is a central government body and one of four component parts of the Nuclear Decommissioning Authority Group. The site's decommissioning programme ranks as the largest environmental restoration project in Europe. Procurement opportunities are managed through Atamis, its tendering portal. Contracts also appear on Contracts Finder and in a quarterly Procurement Plan schedule. No preferred supplier list operates, so any supplier meeting the criteria can tender. Major projects run through the Programme and Project Partners framework, a long-term supplier alliance. Decommissioning work is split among supplier alliances under the Decommissioning Delivery Partnership.

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

Over the past 5 years, most of Sellafield Limited's contract awards have been in IT services, architectural and engineering services and repair and maintenance.
