This programme funded the development and piloting of green finance products and services which can enable uptake of home energy efficiency, low carbon heating and micro-generation retrofit measures.

The Green Home Finance Accelerator (GHFA) provided grant funding to support UK finance providers and other organisations to design, develop and pilot a diverse range of innovative finance propositions which encourage domestic energy efficiency, low carbon heating and micro-generation retrofit.

The objectives of the programme were to:
- support lenders and other providers to develop and pilot a range of innovative green finance products that enable home energy efficiency, low carbon heating, and micro-generation improvements
- develop capability among finance providers in the design, development, and commercialisation of green finance products
- develop partnerships between lenders, investors, energy efficiency, low carbon heating, micro-generation and property value supply chains
- support lenders and other providers to investigate and understand consumer barriers and motivators for energy efficiency, low carbon heating and micro-generation investment
- help to reduce consumer barriers to financing domestic low carbon heating, energy efficiency and micro-generation measures
- establish an evidence base to enable effective design and development of future green finance propositions and inform future policy development
