Summary of the contracting process

London Borough of Hackney commissioned a single integrated Design, Build, Operate and Maintain (DBOM) provider for the Colville Heat Network in Hackney, London. The works cover detailed engineering design, construction, commissioning, operation and maintenance of a low-carbon district heating network serving the Colville and Britannia developments. The scheme includes a new energy centre with air-source heat pumps and associated plant, district heating infrastructure, connections to existing heat network assets where required, and heat-transfer station and district-heating plant construction. It will supply low-carbon heat to more than 1,500 homes, schools, a leisure centre and other connected buildings, supporting the Council’s climate and decarbonisation objectives. The requirement combines engineering design, major heat-network construction and long-term operational services.

The procurement is complete and was awarded through a selective competitive procedure with negotiation. Vital Energi Utilities Limited was selected as the supplier, and the contract is active. The contract was signed on 15 July 2026 for £17,842,041; the original estimated procurement value was £23,500,000. The initial contract term is 15 years, with an option to extend the operation and maintenance services by up to a further 10 years. The process invited candidates on 17 February 2025, with bids due by 19 March 2025 at 12:00, and allowed up to five bidders to proceed from selection. Evaluation weighted quality at 60%, social value at 10% and price at 30%. Bids had to be submitted electronically in English, with variants not allowed.

This award shows Hackney’s demand for suppliers able to take whole-life responsibility for a low-carbon district heat network, from detailed mechanical and electrical design through construction, commissioning and sustained operation and maintenance. A credible competitor for a future requirement would need proven capability in air-source heat pumps, energy-centre plant, district heating infrastructure, heat-transfer stations and integration with existing heat-network assets. It would also need the operational systems and engineering workforce to support reliable heat to homes and public buildings over a long service period. The procurement placed greater emphasis on quality than price and included social value, so delivery planning, technical assurance, community benefits and suitably qualified named staff would be important evidence of capability.
