## Summary

The procurement process for the "Demolition of Harwell Building B401.8" was managed by Nuclear Restoration Services Limited, based in Warrington, United Kingdom. This contract falls under the demolition work category within the works procurement classification, specifically assigned to the Harwell location, in the UKJ1 region. The process was conducted using a limited procurement method, where the DAR Framework allowed an award without a prior call for competition. With the process being in the award stage, the contract was signed on 31st July 2025 and is valued at £2,239,156.23. Relevant industry stakeholders should note that the completion status is listed as "complete", and the supplier awarded was Celadon Alliance, a large company with headquarters in Manchester. Despite the initial status of some lots being cancelled, the procurement for key lot 1 was successfully completed.

This procurement offers significant growth opportunities for businesses specialising in large-scale demolition work and those capable of operating within specialised frameworks such as the DAR Framework. Although the competitive bidding environment had initially attracted two bids, the absence of small and medium-sized enterprise bids suggests a niche for smaller contractors to position themselves for future tenders in the same field. Companies with expertise or interest in nuclear site operations and restoration, particularly those that can align with Nuclear Restoration Services’ objectives and operational scope, are well-suited to compete for similar opportunities.
