A typical domestic air source heat pump installation costs between £10,000 and £18,000 before any grants or funding.
What affects the cost:
- Home size and heat demand — larger homes need a larger heat pump
- Insulation levels — a well-insulated home needs a smaller, less expensive unit
- Radiator upgrades — some homes need larger radiators to work efficiently at the lower flow temperatures heat pumps use
- Hot water cylinder — a new unvented cylinder is usually included
- Pipework and electrical work — the extent of modifications needed to your existing heating system
Available funding in Scotland:
- Home Energy Scotland Grant — up to £7,500 (up to £9,000 for eligible rural and island homes)
- Interest-free loan — up to £7,500, with a 1.5% admin fee capped at £150
- Combined — this can reduce your out-of-pocket cost to as little as £2,500–£10,500 depending on the installation
