Wales Heat Pump Installers 2026

Wales is part of the UK Boiler Upgrade Scheme — Welsh homeowners receive the same £7,500 grant as English homeowners. The Welsh Government additionally runs Nest, a separate scheme offering free heat pumps for low-income households on means-tested benefits. Welsh planning rules broadly mirror England's, with stronger Welsh-language compliance requirements where applicable.
