Summary of the contracting process

Sellafield Limited, a public authority operating in the sub-central government sector, has initiated a procurement process titled "Design support to remediation and security". The process is in the planning stage, with a focus on services related to design support for remediation and security at the Sellafield Site. The procurement is set to be conducted using the Crown Commercial Service framework RM6356, which involves various design support services, including intelligent client support and niche nuclear and specialist support for site remediation and security enhancements. The main location for these services is the United Kingdom. The planned contract period spans from 1 October 2026 to 30 September 2030, and the next update to the notice is scheduled for 11 August 2026.

This procurement offers substantial opportunities for businesses involved in design support services, particularly those with expertise in nuclear remediation and security. It is particularly suited for SMEs due to the structured procurement through a three-tranche competition phase, which allows smaller firms to compete within specific sub-lots. Businesses with capabilities in civil, structural, architectural design, and multi-discipline mechanical, electrical, and instrumentation will find this project attractive. The revised procurement strategy aims to enhance efficiency and project delivery, presenting a conducive environment for business expansion and participation in significant public sector projects.
