Heat Network Transformation Programme provides funding to help improve district and communal heating systems

09 January 2024

The Heat Network Transformation Programme includes the Heat Network Efficiency Scheme, which provides funding for public, private and third sector applicants in England and Wales to improve district heating or communal heating systems, and the Green Heat Network Fund, which supports the development of new and existing low and zero-carbon heat networks.

Round 6 of the Heat Network Efficiency Scheme is now open and closes for applications on 2 February 2024.

Round 7 of the Green Heat Network Fund is now open and closes for applications on 23 February 2024.

In December 2023, the government announced an additional £45m for the HNES from 2025 to 2028. They also announced a further £485m for the Green Heat Network Fund over the same period.

Heat Network Efficiency Scheme

The grant programme worth £32m is for 2023/2024 and 2024/2025 and applications opened in February 2023.

The key aims of the Heat Network Efficiency Scheme are to:

  • Reduce carbon emissions by making heat networks more efficient.
  • Improve customer experience and confidence.
  • Help prepare the heat network market for sector regulation.

The Heat Network Efficiency Scheme is available in the form of capital grants and revenue grants. There is up to £30m available for capital grants across 2023/2024 and 2024/2025. For capital grants, part funding of up to 50% is available for the delivery of eligible intervention/improvement measures. There is up to £2m available for revenue grants across 2023/2024 and 2024/2025. For revenue grants, full funding is available for third party support. Projects can apply for funding across both financial years but must spend all funding within each allocated financial year

The Heat Network Efficiency Scheme will run up to eight funding rounds, which will take place approximately every other month from the start of the scheme with notification letters issued as soon as practicable and subject to approvals. The application submission deadline for the final round will be Friday 10 May 2024. The scheme will close after the full £32m has been allocated so it is advisable to apply for the earlier rounds of funding.

Who can apply?

  • Public sector, private sector or third sector organisations – including housing associations.
  • Operators of existing district heating networks or communal heating networks.
  • Heat networks situated in England or Wales.
  • Legal entities with authority to sign off investment decisions for heat networks they are responsible for.

  • 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.

Who can apply?

The GHNF is open to organisations in the public, private and third sectors in England.
