## Summary

Sellafield Ltd procured works described as “MASFE wash out”, classified as decommissioning services. The requirement concerns wash-out activity as part of the DNWP0074 Lot 1B scope, with the procurement categorised as works rather than goods or general services. Delivery is in the North West of England, at the site associated with postcode CA20 1PG. Sellafield Ltd is the buying organisation. The scope is therefore relevant to contractors providing decommissioning, plant or facility wash-out, controlled dismantling support, and associated site works. Businesses assessing technical fit should interpret the requirement specifically around the MASFE wash-out activity and its delivery within the Sellafield operating environment, rather than as a broad facilities-management or routine cleaning contract.

This procurement has been awarded and the tender is complete. Sellafield Ltd used a selective procedure to call off the requirement from a framework agreement. The tender deadline was 24 July 2026 at 12:00. AtkinsAltrad was awarded the contract on 7 August 2026 for £110,640.55 including the published GBP currency. The awarded contract period runs from 10 August 2026 to 31 December 2026. The award is active. The procurement was structured as Lot 1B within the DNWP0074 requirement. The published process records one awarded supplier and one awarded value; they should not be treated as an invitation to submit for this completed procurement.

This award indicates demand from Sellafield Ltd for specialist, framework-based decommissioning works involving MASFE wash-out activity. A credible future competitor would need practical capability in decommissioning and industrial wash-out operations, together with the systems, supervision and workforce controls needed to work safely on a complex Sellafield site. The buyer’s use of a framework call-off means relevant suppliers would need access to the appropriate framework route and the capacity to respond to its call-off requirements. The procurement was marked as unsuitable for SMEs and voluntary, community or social enterprises, pointing towards established contractors with substantial operational capacity, specialist technical resources, and experience delivering controlled site works at comparable scale and complexity.
