Heat networks: Guidance collection

Net Zero Go says:

Heat networks are a key part of the UK’s transition to Net Zero, providing low carbon, cost-effective heating in densely populated areas by supplying heat to multiple buildings from a central source. This government collection brings together information on heat networks, the Heat Network Transformation Programme (HNTP), and wider efforts to support investment, innovation, and market development.

For local authorities, the collection provides guidance, funding information, and policy updates to help identify, develop, and improve heat network projects. It highlights opportunities to reduce emissions, lower reliance on fossil fuels, and support local energy resilience, while accessing government-backed programmes and industry expertise.

What are heat networks?

A heat network – sometimes called district heating – is a distribution system of insulated pipes that takes heat from a central source and delivers it to a number of domestic or non-domestic buildings. The heat source might be a facility that provides a dedicated supply to the heat network, such as a combined heat and power plant; or heat recovered from industry and urban infrastructure, canals and rivers, or energy from waste plants.

Heat networks form an important part of our plan to reduce carbon and cut heating bills for customers (domestic and commercial). They are one of the most cost-effective ways of reducing carbon emissions from heating, and their efficiency and carbon-saving potential increases as they grow and connect to each other. They provide a unique opportunity to exploit larger scale – and often lower cost – renewable and recovered heat sources that otherwise cannot be used. It is estimated by the CCC that around 18% of UK heat will need to come from heat networks by 2050 if the UK is to meet its carbon targets cost effectively.
