Organisations in England can now apply for capital funding to assist new and existing heat networks in transitioning to low and zero-carbon technologies.

This funding is provided through the latest funding round of the Government’s £288 million Green Heat Network Fund (GHNF).  The fund aims to support the deployment of low-carbon technologies such as heat pumps, solar energy, and geothermal energy. The goal is to enable heat networks to supply clean heating to homes, offices, commercial establishments, and public buildings.

Organisations eligible to apply include:

• Public sector organisations – e.g. local authorities, government departments, NHS trusts and other statutory bodies.

• Private sector entities – registered companies and commercial developers, including corporate project sponsors responsible for heat network projects.

• Third sector organisations – such as registered charities, community energy organisations and similar not-for-profit bodies involved in heat network delivery.

The GHNF is a capital grant fund that supports:

• The commercialisation and construction of new low and zero-carbon (LZC) heat networks, including the provision of cooling.
• The retrofitting and expansion of existing heat networks.

Its objective is to develop and expand the heat network market, addressing challenges associated with decarbonising the UK’s heating sector.

Grant amounts for individual projects will vary, with a maximum of £1 million for commercialisation support.

Round 12 is currently open for applications and will close at 11.59 pm on 25 September 2026.
