## Summary

The London Borough of Hackney procured a low-carbon district heat network for the Colville and Britannia developments in Hackney, London. The works cover detailed engineering design, construction, commissioning, operation and maintenance of the network, including heat-transfer infrastructure and district-heating plant. The scheme is intended to supply low-carbon heat to more than 1,500 homes, as well as schools, a leisure centre and other connected buildings. It supports the Council’s Climate Action Plan and net zero objectives. The main requirement is district heating works, with associated mechanical and electrical engineering design, heat-transfer station construction, and district-heating plant construction. This is a substantial integrated infrastructure project rather than a standalone design, construction or maintenance assignment.

The procurement has been awarded. Hackney used a limited negotiated procedure without a call for competition. The contract was awarded to Vital Energi Utilities Limited on 15 July 2026 for £17,842,041. The broader estimated procurement value was £23,500,000. The contract runs from 15 September 2026 to 31 August 2042, covering the delivery and the initial operating and maintenance period. It includes an initial 15-year term, with an option to extend operation and maintenance services for up to a further 10 years. The award is recorded as active and the tender as complete. The requirement was identified as suitable for small and medium-sized enterprises, although the selected supplier is a large organisation. No lots are identified.

This award shows Hackney’s demand for suppliers able to deliver complete low-carbon heat-network infrastructure and then operate and maintain it over the long term. A credible competitor for a future requirement would need coordinated capability across mechanical and electrical engineering design, district-heating plant and heat-transfer station construction, commissioning, network operations and planned maintenance. Experience integrating heat supply for large residential developments with public buildings such as schools and leisure facilities would be directly relevant. The project also favours businesses able to demonstrate practical delivery of low-carbon energy schemes, reliable long-term asset performance and coordination across design, build and operational teams. The stated SME suitability indicates that smaller specialist firms may be well placed to participate, including through delivery partnerships covering the full DBOM service.
