Summary of the contracting process

Southampton City Council has successfully awarded the contract for the "Holyrood Replacement Works (Heat Efficiency Scheme) - SCC-SMS-0585" to CLC Contractors Limited. This project falls under the industry category of "Gas heaters" and involves heating works and gas-fitting installations. With the contract valued at £7 million, it covers the replacement of an existing heat network system with a two-pipe system served by gas boilers, with the possibility of Phase 2 works, focusing on external pipework and boiler room upgrades. These works are to be completed starting from 20th October 2025 until the end of December 2027 across various locations, including the United Kingdom and several international territories listed in the tender.

This open procurement method creates a substantial business growth opportunity, particularly for firms specialising in heating systems, gas-fitting installations, and similar construction and maintenance services. Companies offering expertise in efficient, safe, and cost-effective installation and maintenance of heating systems would be well-placed to deliver on the project's requirements and potentially secure further opportunities with Southampton City Council, especially if Phase 2 proceeds. Considering the competitive value and scope, even firms focusing on international collaborations could benefit by engaging with this complex procurement opportunity.
