## Summary

Sellafield Limited has completed a procurement for the maintenance and technical support of control system equipment, manufactured by ABB Limited. 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. ABB Limited, being the original equipment manufacturer, was the sole supplier due to its unique technical knowledge and controlled intellectual property. The contract's framework supports companies that provide ongoing service and maintenance, ensuring operational continuity and compliance with existing warranties and standards.

## Notice

The provision of maintenance & technical support of in situ control system equipment used by Sellafield Ltd which have been manufactured and supported by the original equipment manufacturer (OEM) - ABB Limited. The scope includes: on-site support, breakdown support, telephone support, servicing, preventative maintenance, software updates, and supply of associated spare parts.

### Procurement Information

It has been determined that in current circumstances that competition is absent for technical reasons pursuant to Schedule 5 paragraph 5(a)(b) and 7(a)(b) of the Procurement Act 2023. Justification for the award is as follows: The Contract includes the provision of proprietary software, firmware and embedded components with intellectual property rights owned by the original equipment manufacture (OEM) - ABB Limited. A change in supplier would result in the contract authority receiving software/goods that are different from, or incompatible with, the existing works and using alternative suppliers could invalidate warranties controlled by the OEM. Changing suppliers would require reverse engineering, revalidation, and potential compatibility issues which could impact Sellafield's ability to operate its existing control systems. The OEM maintains site and system specific technical knowledge and history of the existing ABB Limited equipment installed on the Sellafield site.
