Provision of Cambridge City Centre District Heat Network

Since June 2023 Cambridge City Council has been working with consultants and academic partners to develop an Outline Business Case for a City Centre District Heating Network. Detailed Project Development has now completed, proposing a low carbon network using air source and river source heat pumps, and supported by a transition to electric boilers from gas boilers to supplement peak heat demand.

This work has been brought forward through a partnership between the City Council, the County Council, and 19 Academic institutions with significant heating demand in the city centre. Connections to many of these partner heat loads now forms the basis of the Minimum Viable Product identified for delivery through a Partner-invested Joint Venture Partnership, and with strategic ambition to expand such a network across the City in the long term, informed by an informal Heat Zoning review which has also been completed.

A Cambridge City Centre Heat Network represents a timely and valuable opportunity for Cambridge's academic institutions and public-sector organisations, who all share ambitious decarbonisation goals, and we are now seeking expressions of interest from potential partners who wish to be appointed to the established partnership to provide Design, Build, Operation and maintenance Services, inclusive of metering and billing. We feel that establishment of a new district heating network in a city of Global significance is a momentous opportunity, and we wish to procure a DBOM partner who shares our vision and understanding of the opportunities which this may bring.

We request that all interested parties put forward contact details for appropriate representatives who wish to be involved with early market testing on the Contracting opportunity, with meeting dates to be confirmed between 23rd February and 6th March 2026.
