## Summary

The recent procurement process led by Nuclear Restoration Services Limited involved the award of a contract titled "SILWE HVAC Commissioning Support," focused on providing consultancy services for HVAC system commissioning at the Hunterston A decommissioning site. The buying organisation, a public authority within sub-central government, conducted the process under limited competition, utilizing consultants to handle both offsite document preparation and onsite technical support. With significant activity in the services category, the process has reached the award stage, with the contract commencing on 8th December 2025 and scheduled to conclude on 31st March 2026, subject to extensions in case of delays. The legal basis was UKPGA 2023/54, supporting operations in Warrington, UK.

This tender offers opportunities for specialists in technical consultancy services, particularly those with experience in HVAC systems considering its classification under CPV code 71621000. The awarded contract, valued at £21,857.55 gross (£26,229.06 including potential extensions), provides a keen opportunity for businesses like Brierley Consultants Limited, an SME, which successfully secured the award. SMEs, especially those positioned in technical consultancy and equipped with capabilities in both offsite and onsite project support, are well-suited to engage in such opportunities for substantial business growth, leveraging the chance to work on high-profile restoration projects.
