## Summary

Sellafield Limited procured machinery maintenance rationalisation and compliance assessment services for its encapsulation plants at the Sellafield site. The work was to review and rationalise maintenance prompts, carry out assessments under the Provision and Use of Work Equipment Regulations 1998 (PUWER), and manage the resulting Change Control Requests. The purpose was to establish maintenance arrangements that are fit for purpose and legally compliant, while improving operational and maintenance efficiency. This is specialist industrial maintenance and engineering support connected to regulated work equipment, rather than a general machinery repair service.

The procurement is complete and the contract was awarded to Cumbria O and M Services Ltd. The contract was signed on 12 October 2026, with a value of £3,180,929.28. The tender used a restricted procedure and was assessed on technical quality, weighted at 80%, and price, weighted at 20%. The work was grouped in one lot, but that lot is recorded as cancelled even though the award and contract are active; this status conflict makes the lot outcome unclear. The procurement data records one bid. No contract period or end date is stated.

For suppliers seeking comparable work with Sellafield, the award indicates demand for integrated engineering support in operating encapsulation plants: maintenance prompt rationalisation, PUWER assessment and control of resulting engineering changes. A credible competitor would need to demonstrate practical machinery-maintenance expertise, the ability to assess work equipment against regulatory requirements, and disciplined change-control capability, as well as the capacity to coordinate the strands into a legally compliant, operationally workable maintenance approach. Technical quality carried substantially more weight than price in the evaluation, so evidence of sound methodology and relevant delivery experience would be important alongside cost competitiveness. The selected supplier is an SME, showing that this requirement was delivered by a specialist smaller business; the contract’s scale nevertheless calls for the resources and management capacity to deliver a substantial, multi-faceted assignment.
