Air source heat pump installation in Scotland costs £12,000-£18,000 before grants. The Home Energy Scotland (HES) Grant provides up to £7,500 (£9,000 for rural properties with the £1,500 uplift) plus a £7,500 interest-free loan, reducing net cost to as low as £3,000. Heat pumps also qualify for 0% VAT until March 2027. They replace gas, oil, or electric heating and deliver 3-4x the energy they consume. Scottish Energy Efficiency is MCS-certified and handles the full HES Grant application.

Warmer Homes Scotland
Fully funded heat pump for qualifying low-income households. Apply via Home Energy Scotland (0808 808 2282). Covers full cost of heat pump and insulation improvements.
Boiler Upgrade Scheme — England & Wales Only
The BUS (£7,500 grant) is not available in Scotland. Scotland has the HES Grant instead, which provides the same £7,500 grant plus an additional £7,500 interest-free loan — making it more generous than the English scheme.
