Flats
Ground-floor flats benefit from low heat demand, small systems, and short pipework runs. Upper-floor flats need longer pipe runs and may face leasehold restrictions. For detailed flat-specific guidance, see our 2-bed flat cost guide.
Terraced Houses
Sandwiched between neighbours, terraced houses have moderate heat demand. Mid-terrace properties have no side access, so the outdoor unit goes in the front or back garden. After grant: £500-£3,500.
Semi-Detached Houses
Britain's most common property type and the benchmark for heat pump costs. Most have side access for the outdoor unit. After grant: £2,500-£6,500. See our 3-bed semi cost guide.
Detached Houses
Four exposed walls mean higher heat demand and larger systems. Plenty of garden space makes placement easy. After grant: £4,500-£9,500. See our 4-bed detached cost guide. For very large properties, consider ground source heat pumps.
Bungalows
Excellent for heat pumps -- single-storey design simplifies pipework and ground-level access is ideal. Larger roof area relative to floor area increases heat demand slightly. After grant: £1,500-£5,500.

Properties with solar panels or suitable roofs for solar benefit from reduced electricity costs alongside the heat pump.
