Summary of the contracting process

The Department for Environment, Food & Rural Affairs (DEFRA), based in London, United Kingdom, has completed the procurement process for the project titled "B57 HVAC & Electrical Infrastructure Upgrades." This construction work falls under the CPV classification 45000000 and was executed under a selective procurement method, specifically a call-off from a framework agreement. The project involves significant upgrades, including the removal and replacement of existing air handling and condensing units, and the installation of new water systems. The location for this project is in the South West region, postal code KT15 3NB. The contract, valued at £5,802,023.69, commenced on 23rd June 2026 and is set to end on 31st May 2027.

This contract presents substantial opportunities for businesses engaged in large-scale construction and infrastructure works, particularly those specialising in HVAC systems and electrical upgrades. While DEFRA's procurement method specified selective tendering, businesses involved in framework agreements or similar consortiums may find potential in pursuing similar future opportunities. Such projects can lead to business growth by enhancing expertise and credibility in high-value, government-backed infrastructure assignments. Companies like Walter Lilly & Co. Limited, who secured this contract, illustrate the viable prospects for established builders and specialists offering comprehensive engineering solutions.
