What it funds
The Heat Network Efficiency Scheme (HNES) provides funding to public, private and third sector applicants, to support improvements to existing district heating or communal heating projects in England and Wales that are operating sub-optimally and resulting in poor outcomes for customers and operators. Projects can apply to HNES for either revenue or capital grant funding: Revenue grants – grants to fund procurement or mobilisation of external third-party support to carry out Optimisation Studies. These studies will assess heat network projects to identify causes of sub-optimal performance and recommend costed intervention or improvement measures. Capital grants – grants to part-fund the delivery (installation) of eligible intervention/improvement measures.
