Fund Name

Green Heat Network Fund

Project Value




The Green Heat Network Fund (GHNF) will provide capital grant support for the commercialisation and construction of new low- and zero-carbon heat networks, and the retrofitting and expansion of existing ones, to address some of the challenges of decarbonising the UK’s heat sector.

This is initially a £288m fund.

Fund details

The GHNF objectives are to:

  • Achieve carbon savings and decreases in carbon intensity of heat supplied.
  • Increase the total amount of low carbon heat utilisation in heat networks (both retrofitted and new heat networks).
  • Contribute towards market transformations across the investment landscape and supply chain that will better prepare the heat network sector for further decarbonisation.

To address some of the challenges of decarbonising the UK’s heat sector.

  • Accessing Heat Sources (SUPPORTED) – such as capturing waste heat from an industrial process, energy from waste, wastewater, geothermal, etc.
  • Low-Carbon Generation (SUPPORTED) – energy centres, low-carbon generation and associated plant, controls, etc.
  • Primary Heat Network Distribution (SUPPORTED) – distribution pipework – both above and below-ground for transmission and distribution of low-carbon heating and cooling.
  • Secondary Distribution (LIMITED SUPPORT) – our support for secondary systems within consumer premises is limited to upgrading existing infrastructure.

Heat networks are an established method of distributing heat that can utilise otherwise wasted energy, provide grid balancing services in an increasingly electrified heat market and offer low carbon heat at competitive prices to households and businesses alike.


The GHNF is open to organisations in the public, private and third sectors in England and will fund up to, but not include, 50% of a project’s total combined commercialisation and construction costs. This is Round 8, we expect that Round 9 will open following the close of Round 8 and close in January 2025.
