The Heat Pump Investment Accelerator Competition (HPIAC), worth up to £90 million in total, aims to bring forward investment in the UK heat pump manufacturing supply chain. It is open to proposals to manufacture heat pumps and/or heat pump components (including thermal storage that can be paired with a heat pump) to support the construction of new factories or the expansion, re-tooling, re-working or re-purposing of existing buildings.

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.

The Boiler Upgrade Scheme (BUS) supports the decarbonisation of homes and small and medium non-domestic buildings in England and Wales. The scheme provides upfront capital grants of up to £7,500 to encourage property owners to replace existing fossil fuel heating with more efficient, low carbon heating systems including heat pumps and biomass boilers.
