Summary of the contracting process

Southampton City Council has completed the award process for the "Holyrood Replacement Works (Heat Efficiency Scheme)," which involves replacing an existing heat network with a more efficient two-pipe system powered by gas boilers. The contract is valued at £1,147,672 and will commence on 1st November 2025, concluding on 31st December 2026. The procurement was conducted through an open procedure, attracting four bids, including two from small and medium-sized enterprises (SMEs). Located in Southampton, United Kingdom, this project, categorised under the works industry, offers a significant opportunity for the chosen contractor, C.L.C. Contractors Limited, to execute this governmental infrastructure initiative.

This tender presents substantial opportunities for businesses specialising in gas-fitting installation and heating works. Given the significant scope for Phase 2, which includes potential extensions for designing and building, enterprises that can offer cost-effective and high-quality project management will benefit significantly. SMEs in the region with expertise in external pipework and boiler room upgrades will find this contract particularly appealing, as the council has demonstrated a preference for such firms in the bidding process. The initiative not only underlines the need for technical proficiency but also allows for long-term engagement with a potential extension valued between £2.5m and £5m, creating growth prospects for competent businesses.
