## Summary

Sellafield Limited commissioned maintenance rationalisation and equipment-safety assessment services for its encapsulation plants. The work covers reviewing and rationalising maintenance prompts, carrying out assessments under the Provision and Use of Work Equipment Regulations 1998 (PUWER), and managing the resulting change control requests. Its purpose is to bring equipment maintenance to a fit-for-purpose and legally compliant position, while improving operational and maintenance efficiency. The procurement is categorised as machinery repair and maintenance services (CPV 50530000). Delivery is associated with Sellafield’s site at Seascale, Cumbria.

The procurement is complete and the contract was awarded to Cumbria O & M Services Ltd. The award date was 12 October 2026, and the contract runs from 12 October 2026 to 31 March 2028. The awarded value is £3,284,910.96. The requirement was procured selectively as a call-off from a dynamic purchasing system. The tender deadline was 4 September 2026 at 16:00. The published information gives no separate evaluation criteria or lot breakdown. Sellafield Limited is the buyer.

For suppliers considering comparable future work for Sellafield, this award demonstrates demand for integrated maintenance engineering and equipment-compliance services at an encapsulation plant. A credible competitor would need to review and rationalise maintenance regimes, apply PUWER requirements in equipment assessments, and take resulting change control requests through management. The work also calls for an approach that connects legal compliance with practical improvements to plant availability and maintenance efficiency. The scale of the award indicates a substantial, multi-stage service rather than a narrow assessment exercise. The selected supplier was an SME, although the procurement was marked as unsuitable for SMEs; businesses should therefore assess the likely capacity and delivery demands carefully. The route used was a call-off from a dynamic purchasing system.

## Notice

SL have a requirement to rationalise maintenance prompts, carry out Provision and Use of Work Equipment Regulations 1998 (PUWER) assessments, and manage resulting Change Control Requests (CCR's) in encapsulation plants to get to a fit for purpose and legal position that ensures maintenance is completed to maximise the operational and maintenance efficiency.
