## Summary

The Nuclear Restoration Services Limited has awarded the Decommissioning & Asbestos Removal (DAR) framework, identified by tender ID DAR/FW/002–VEAT 2026, to five suppliers: Celadon Alliance, Costain Limited, Aureos Highways, Nuvia Limited, and KAEFER LIMITED. The framework is intended for decommissioning and asbestos removal activities across multiple UK sites, including Dounreay and several Advanced Gas-cooled Reactor (AGR) stations transferred from EdF. The process, completed by 1 March 2026, utilises a limited procurement method without the prior publication of a call for competition, and adheres to regulations under 72(1)(e), ensuring no substantial changes to the original framework.

This procurement presents extensive opportunities for businesses specialising in civil, mechanical, and electrical enabling works, environmental assessments, decommissioning, and asbestos remediation. Suitable contenders include those adept in demolition, waste management, and project management in both conventional and radiological contexts. Large-scale suppliers interested in contributing to nuclear site restoration will find significant prospects for growth through collaboration on this project, reinforcing technical expertise and market presence in high-stakes industrial clean-up operations.

### Procurement Information

NRS considers that this modification is permitted under Regulation 72(1)(e), having assessed it against the criteria for being substantial in Regulation 72(8). The inclusion of the additional sites does not render the framework agreement materially different in character from that originally procured; it does not introduce new conditions that would have affected participation; it does not alter the economic balance of the framework in favour of any contractor; it does not extend the qualitative or technical scope of the framework beyond that anticipated in the original procurement documentation; and it does not replace any contractor. The additional sites require the same nature, type and technical scope of DAR works as those identified in the original tender documents and call offs will continue to be awarded in accordance with the original commercial terms, pricing mechanisms and overall value ceiling. No amendments to rates, commercial conditions or risk allocation have been made. Accordingly, the modification is not substantial and a new procurement is not required.
