Summary of the contracting process

Sellafield Limited commissioned decommissioning works described as “SSRF Improvements” for its Waste Operating Unit. The requirement is categorised as decommissioning services and falls within the works category. Delivery is in the North West of England, with Sellafield Limited based in Whitehaven, Cumbria. The scope is identified as DNWP0003/LOT4/Waste OU, indicating a defined part of a wider requirement. The selected contractor is AtkinsAltrad, an organisation based at Westlakes Science Park in Cumbria. The work is therefore suited to businesses involved in site-based decommissioning and improvement works, particularly those able to operate in the North West and within the Sellafield supply chain.

The procurement has been completed and awarded. Sellafield Limited used a selective procedure to make a call-off from a framework agreement. Bids were due by 30 April 2026 at noon. The contract was awarded to AtkinsAltrad on 5 August 2026 for £734,360.44, inclusive of the stated GBP currency. The contract period runs from 10 August 2026 to 15 December 2026. The award is active and covers the single identified requirement for Waste Operating Unit SSRF Improvements. Participation was not identified as suitable for small or medium-sized enterprises or voluntary, community and social enterprises. The available procurement information does not set out separate evaluation weightings or criteria.

For suppliers that did not win this award, the procurement indicates demand for specialist decommissioning and improvement works within Sellafield’s Waste Operating Unit. A credible future competitor would need relevant delivery experience in decommissioning environments, the technical capability to carry out improvement works safely and reliably, and sufficient operational capacity for a defined, time-limited assignment. The route to market is also significant: this requirement was awarded through a framework call-off, so businesses seeking comparable work would need to hold an appropriate framework position or work through an eligible framework supplier. The award also indicates that Sellafield’s requirement is substantial enough to support a specialist contractor rather than a general works provider.
