Heat network zoning
Identifying and designating zones where heat networks provide the lowest-cost, low carbon heating option.

Heat network zoning will fundamentally transform the development of heat networks in towns and cities across England.
By designating zones where district heat networks are expected to offer the lowest-cost solution for decarbonising heat, local communities will have the tools to accelerate the development of heat networks, ensuring that more homes and businesses can access greener, cheaper heat.

How zoning will be delivered
The Energy Act 2023 provides the powers for government to implement heat network zoning in England through regulations.
We consulted on the further detail of heat network zoning and published our response in January 2026..
Where zones will be located
We have developed a national zoning model that identifies heat network opportunity areas. This involves using different data such as building type, size and existing energy use to help identify where heat networks may be located.
The model has been tested and refined with pilot projects in 28 English towns and cities. Some of these areas are now being progressed as the first heat network zones, ahead of heat network zoning legislation coming into force. Details of these initial zones are available via recordings made from a series of market engagement webinars.
