## Summary

Nuclear Restoration Services Limited has engaged in a procurement process for diving services at Hunterston B, aligning with the UK's nuclear decommissioning program. The contract, titled "HNB - Diving Services", falls under the public authority - sub-central government classification. The procurement stage is at the award phase since the contract status is complete, with a direct award given to Reach Engineering & Diving Services Limited due to technical necessity and regulatory considerations. Located in Warrington, with operations at Hunterston B facility, the contract period spans from 1 April 2026 to 31 December 2027, with a potential extension up to 31 December 2028. The direct award method supports this transition, ensuring safety and compliance, with an estimated contract value of £213,334, not exceeding £256,000.

This procurement opportunity presents significant business growth potential for firms specialising in diving and engineering services, particularly those with capabilities in nuclear facility operations. The contract is pivotal in supporting the seamless transition of the Advanced Gas-Cooled Reactor sites, offering sustained involvement for businesses with requisite technical expertise and reliability. Although a direct award indicates limited initial competition, future requirements will proceed through established procurement processes, opening doors for businesses adept in environmental compliance and innovative solutions in engineering services. Such contracts offer strategic avenues for firms seeking to integrate into critical infrastructure projects within the UK’s nuclear sector.

## Notice

Diving Services at Hunterston B

### Procurement Information

As part of the UK's nuclear decommissioning programme, Nuclear Restoration Services (NRS) will begin taking ownership of assets and the responsibility for the Advanced Gas-Cooled Reactor (AGR) sites from EDF Energy Nuclear Generation Limited (EDF). This transition, starting with Hunterston B in spring 2026, marks a key milestone in ensuring the continued safe, secure and cost-effective decommissioning of the UK's nuclear legacy. NRS is committed to transparency and collaboration throughout this transfer process, working closely with EDF, regulators and stakeholders to deliver a seamless transfer whilst maintaining the highest standards of regulatory, safety and environmental compliance. In line with this commitment, NRS therefore intends to make a direct award in accordance with Section 41 of the Procurement Act 2023 and wishes to advise that the existing EDF contract with Reach Engineering & Diving Services Limited, as detailed in this notice, is being novated to Nuclear Restoration Services (NRS) as part of the AGR site transfer process. This is a direct award for the purposes of Procurement Act 2023 and is being made pursuant to Paragraph 6 of Schedule 5 to the Procurement Act 2023 NRS considers Paragraph 6 applies as the services provided by Reach Engineering & Diving Services Limited are critical to the ongoing operation of Hunterston B and it would create significant technical difficulties and unacceptable regulatory risks to NRS for another supplier to supply the Services at this time. Following completion of this novated contract, all future requirements will be progressed through NRS's established procurement processes and in continued compliance with the Procurement Act 2023 (PA23). Reach Engineering & Diving Services Limited is neither an excluded or excludable supplier. A Contract Award Notice and Contract Details Notice will follow in accordance with Procurement Act 2023. ** Please note ** This is a framework and will be called off as and when required with no current commitment.
