The Green Heat Network Fund (GHNF) is a 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.


You can now apply for funding that could be drawn down in financial years 2023-2024 through to 2026-2027.

We expect that round 6 will close around the end of September: we will publish revised guidance for applicants in the Summer which will confirm the dates.

How to apply

We are currently reviewing the guidance to reflect changes to the scheme rules and timescales. The guidance attached to this page is for indicative purposes only.

If you are working on an application for round 6 or beyond, you can continue to develop the project, but we recommend that you wait for the updated Round 6 guidance and application form before you commit time to drafting a submission.

The new guidance will include full details of available support, scheme criteria, application process and the application round timings. Subscribe to the Triple Point mailing list to be notified when the revised guidance is available.

For further information, email the GHNF delivery partner, Triple Point Heat Networks Investment Management at or visit the Triple Point Green Heat Networks Fund page.


The GHNF, launched in 2022, is a core element of the government’s Heat Network Transformation Programme (HNTP) and follows on from the progress and development made by the Heat Network Investment Project (HNIP) and the 2021 Green Heat Network Fund Transition Scheme.

The GHNF is led by our delivery partner, Triple Point Heat Networks Investment Management (TP Heat Networks) led by Triple Point and supported by AECOM, Asteros Advisers, Amberside Advisors, Gemserv and Lux Nova. Find out more about the Delivery Partner and resources.
