Award Notice
Summary of the contracting process

Sellafield Ltd procured works to excavate and pour the HEx-1 laydown area. The requirement concerns covered or partially covered excavation works, including excavation and concrete pouring for the laydown area. It is a construction project delivered in North West England, associated with Sellafield Ltd’s site requirements. The buying organisation is Sellafield Ltd, based in Whitehaven. The procurement is categorised as works rather than goods or services. The scope is focused on a defined laydown-area package rather than a broad construction or facilities-management requirement, so it is most relevant to contractors with direct experience of excavation, ground preparation and concrete or structural pours. The requirement was procured as a specific package within Sellafield Ltd’s wider delivery programme.

The procurement is complete and was awarded through a selective call-off from a framework agreement. The contract was awarded to AMENTUM CLEAN ENERGY LIMITED on 9 September 2026 for £3,425,940.30 including the stated currency of GBP. The overall estimated procurement value was £4,000,000. The contract runs from 9 September 2026 to 1 May 2028. The tender submission deadline was 8 September 2026 at 12:00. Evaluation resulted in an active award to the named supplier. The process was not divided into separately described lots in the available outcome, although the title identifies the package as LOT1A. The opportunity was marked as unsuitable for small and medium-sized enterprises and voluntary, community or social enterprises, indicating a requirement aimed at established specialist contractors.

For suppliers that did not win, this award demonstrates demand from Sellafield Ltd for substantial, specialist site-construction packages involving excavation, laydown-area preparation and concrete pouring. A credible competitor for comparable work would need proven capability in covered or partially covered excavation, groundworks, concrete placement and the management of an integrated construction package. The procurement route also shows that framework access is commercially important: suppliers would need to be positioned within the relevant framework and able to compete through its selective call-off process. The scale and specialist setting favour established contractors with sufficient operational capacity, experienced site teams, robust quality and safety controls, and a track record delivering complex works for major infrastructure or industrial clients.
