Summary of the contracting process

Sellafield Limited is progressing with a planned procurement for design support to process engineering, which spans both nuclear and non-nuclear facilities. This procurement process, identified under the tender ID "C25789", is being advanced via a Crown Commercial Service framework (RM6356). The procurement falls under the services category and targets the design support industry. The contracting process is currently in the planning stage, with key dates including the contract period starting 1 October 2026 and ending 30 September 2030. Based in Warrington, United Kingdom, Sellafield Limited is a public authority operating within a sub-central government framework. Updates to the procurement strategy, focused on tranche-based competition phases, have been issued to enhance efficiency.

This tender represents substantial opportunities for businesses specializing in engineering design, particularly those that offer comprehensive process engineering support across various sectors, including nuclear. Given the long contract duration and segmented competition approach, businesses, especially SMEs, can strategically engage through framework agreements to secure parts of the contract. Enterprises that demonstrate agility, sizeable technical capacity, and experience in civil, structural, and architectural sectors or those with capabilities in remediation and legacy projects are well-positioned to compete for this tender. The revised procurement strategy offers transparent entry points into a complex but rewarding sector, promoting economic expansion and innovation in the engineering consultancy market.
