## Summary

Sellafield Limited has recently completed a procurement process involving the maintenance and upgrade of its 3m³ box production assets located within the Stainless Metalcraft facility in Chatteris, Cambridgeshire. This contract, awarded on 18th June 2026 and scheduled to start on 2nd July 2026, falls under the services category with a total gross value of £900,000. The direct award method was used due to technical reasons, with the procurement process guided by the Public Authority regulations under the legal framework of the UK Public Procurement Act 2023/54. The centre of operations for this project is within the UKD11 region, with a project endpoint scheduled for 2030.

This tender provides significant growth opportunities for businesses within the waste material containers and plant maintenance sectors. Due to the specific technical and operational requirements associated with the assets' location, the contract necessitates a supplier capable of managing complex upgrades and maintenance within an integrated production environment. Large-scale enterprises that specialise in engineering, operational sustainability, or integrated manufacturing services could leverage this contract to enhance their profile and capabilities within the sub-central public authority market sector.

## Notice

### Procurement Information

Sellafield Ltd intends to award a contract to Stainless Metalcraft Chatteris (SMC) pursuant to Schedule 5 paragraph 6(a) and 6(b) of the Procurement Act. Only SMC is capable of delivering the required services due to technical and operational exclusivity and the absence of any reasonable alternative. The contract relates to the maintenance and associated upgrade activities of Sellafield Ltd-owned assets that are physically installed, integrated, and operated within the SMC manufacturing facility in support of the 3m3 production line. Due to their location and integration within SMC's live production environment, only SMC has lawful access, operational control, and the technical capability to safely maintain and service these assets. In accordance with Schedule 5, paragraph 6(a), the services can only be supplied by a particular supplier for technical reasons. In accordance with paragraph 6(b), there are no reasonable alternative suppliers, as no third party can perform the maintenance independently without relying entirely on SMC for access and execution of the services.
