## Summary

The procurement process for the provision of security barriers and associated services is managed by Nuclear Restoration Services Limited, a public authority within sub-central government located in Warrington, United Kingdom. The contract, titled "HNB - Provision of Security Barriers and Associated Services", is aimed at supporting the UK's nuclear decommissioning programme, specifically the Advanced Gas-Cooled Reactor sites beginning with Hunterston B in spring 2026. This procurement is at the award stage, with the contract having been signed on 31 March 2026, and set to commence from 1 April 2026 to 31 March 2027, with a potential extension until 2028. The procurement method used is a direct award as per Section 41 of the Procurement Act 2023, stressing the technical necessity to maintain continuity with Allen Fencing Limited, a large supplier based in West Byfleet.

This tender presents significant opportunities for businesses within the security barrier and maintenance industry segments, especially those with expertise in handling critical operations such as the decommissioning of nuclear facilities. The transition of these services is vital for the regulatory compliance and safety of Hunterston B, and businesses that offer specialised goods and services in safety barriers and security equipment maintenance would be ideally positioned to compete in this sector. Allen Fencing Limited, being the awarded supplier due to their capability to provide the requisite services without technical difficulties, exemplifies the scale and expertise necessary to thrive in such a niche and high-stakes industry. Future procurement processes will adhere to established guidelines, potentially allowing other skilled suppliers to engage with Nuclear Restoration Services' contracting needs as the decommissioning programme progresses.

## Notice

Provision of Security Barriers and Associated 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 Allen Fencing 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 Allen Fencing 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 Goods 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). Allen Fencing 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.
