Further support for heat networks
Heat Networks Delivery Unit
The Heat Networks Delivery Unit (HNDU) provides support to local authorities in England and Wales through the early stages of heat network development, including:
- heat mapping
- energy master planning
- techno-economic feasibility
- detailed project development
Green Heat Network Fund
The Green Heat Network Fund (GHNF) is a 3 year capital grant fund that supports:
- the commercialisation and construction of new low and zero carbon (LZC) heat networks (including the supply of cooling)
