Award Notice
Summary of the contracting process

Sellafield Limited procured decommissioning services for its Waste OU under the CLESA Design requirement. The work was to be delivered in North West England. The requirement is identified as a call-off for Lot 4, linking it to a wider procurement arrangement, but the available description does not detail the specific decommissioning tasks or outputs. This is a services contract for suppliers whose work covers decommissioning in the nuclear sector or comparable complex industrial environments. The buyer is Sellafield Limited, based in Whitehaven, Cumbria.

The procurement is complete and was awarded to AtkinsAltrad. The award date was 15 April 2026, and the contract period runs from 15 April to 15 May 2026. The awarded value is £128,775.08. The original estimated procurement value was £200,000. The buyer used a selective procedure, making a call-off from a framework agreement. The tender deadline was 24 February 2026 at 12:00 UTC. The requirement was designated unsuitable for SMEs and voluntary, community and social enterprises. No lots or evaluation criteria are detailed in the published procurement data, beyond the Lot 4 reference in the title.

This award demonstrates demand from Sellafield Limited for decommissioning services through a framework call-off, with the work delivered in the North West. Suppliers seeking to compete for comparable requirements from this buyer would need to show relevant decommissioning expertise and the capacity to deliver a focused piece of work within a short contract period. The selected supplier, AtkinsAltrad, provides a benchmark for the type of provider chosen, but the procurement data does not state specific technical standards, accreditations, staffing requirements or past-performance thresholds. The SME and VCSE suitability flags indicate that this requirement was not considered suitable for those organisations. Businesses best positioned for a future equivalent requirement are therefore likely to be established suppliers able to undertake decommissioning work for Sellafield through its framework arrangements.
