This contract involves the comprehensive service and maintenance of systems at Sellafield's site in Warrington, United Kingdom, and falls within the category of installation services for guidance and control systems. The procurement process was executed as a direct award owing to technical reasons, specifically the proprietary nature of ABB's software and components. The award was signed on 27 March 2026 and the contract period is from 1 April 2026 to 31 March 2027. The award was valued at £915,829 with a gross amount of £1,098,994.80.

This contract presents growth opportunities for large businesses capable of delivering technical and maintenance services in the nuclear sector. Businesses with expertise in managing proprietary control systems and those familiar with site-specific operational requirements are well-suited to compete in similar future tenders.
