## Summary

Sellafield Ltd commissioned de-planting work at the R1S Blower House, a decommissioning works project at the Sellafield site in the North West of England. The requirement is described as removal of plant from the blower house; the procurement record does not give a more detailed breakdown of the equipment or work activities. This is specialist nuclear-site decommissioning work rather than a general building or plant-removal contract. Its location is identified by the Sellafield postcode area, CA20 1PG. The buyer is Sellafield Ltd, based in Whitehaven. The scope and delivery location point to suppliers with relevant experience of safely carrying out de-planting and decommissioning work in a nuclear site environment.

The procurement is complete and AtkinsAltrad was selected for the contract. The award was made on 15 October 2026, for £4,548,408.55. The contract period runs from 15 October 2026 to 2 October 2028. Sellafield used a selective procedure to call off the requirement from a framework agreement. The tender deadline was 23 June 2026 at 12:00. The award is active. The published procurement information identifies a single requirement and a single successful supplier. No evaluation criteria or detailed eligibility conditions are set out in the procurement data, so the basis on which competing framework suppliers were assessed cannot be described further.

For suppliers that did not win, this award demonstrates demand from Sellafield for substantial, site-specific de-planting work at the R1S Blower House. A credible competitor for a comparable requirement would need to show that it can plan and deliver plant removal and decommissioning safely within a nuclear site, with the technical capability, experienced workforce and operational controls appropriate to that environment. The work was awarded through a framework call-off, so framework participation and the ability to compete within the relevant arrangement are important routes to this buyer’s requirement. The opportunity was not identified as suitable for SMEs or voluntary, community and social enterprises, indicating that suppliers should assess whether they have the scale and specialist capability to undertake a large, complex site project.
