## Summary

The Department for Environment, Food & Rural Affairs has completed a procurement process for the project titled "B265 Mice Upgrades (Suite C)", classified under the industry category of laboratory building construction work. This project involves modifications to facilitate the handling and containment of Transmissible Spongiform Encephalopathies (TSE) mice at B265 Suite C. Located in the South East of the United Kingdom, with postal code KT15 3NB, this direct procurement process used a single tender action below the threshold. The awarded contract, valued at £176,567.47, with an initial estimated value of £250,000, was published on 31st July 2026 and is set to run from 21st July 2026 to 2nd November 2026, marking the award stage of the procurement.

This tender represents substantial opportunities for businesses involved in laboratory construction and modifications, especially those specialising in pathogen containment and compliance. While large-scale businesses like the awarded supplier, Walter Lilly & Co. Limited, are likely candidates due to the project's nature and scale, companies with expertise in complex laboratory upgrades and pathogen handling compliance might find tremendous growth potential in similar future tenders issued by government departments. Such projects not only enhance credentials in high-standard construction but also expand market reach in the niche sector of laboratory facilities tailored for specialised scientific work.

## Notice

The Contractor shall design, supply, install, test and commission all modifications required to B265 Suite C to facilitate the interim accommodation of Transmissible Spongiform Encephalopathies (TSE) mice from Q4 2026 pending completion of B448.
