The Green Heat Network Fund (GHNF) is a 3 year £288 million capital grant fund that will support:

  • the commercialisation and construction of new low and zero carbon (LZC) heat networks (including the supply of cooling)
  • the retrofitting and expansion of existing heat networks

It aims to develop and grow the heat network market and to address some of the challenges of decarbonising the UK’s heat sector. Find out more about heat networks.


The GHNF is open to organisations in the public or private sectors in England.

Individuals, households and sole traders cannot apply.


The GHNF main scheme Round 2 is open to applications until 26 August 2022.
