What affects heat pump prices?
The six biggest factors that push your heat pump quote up or down.
Pump size (kW)
Sized to your heat loss. Well-insulated homes need smaller, cheaper units.
Radiator upgrade
Many homes need larger radiators (£80–£250 each) or a fan-coil for efficient heat pump operation.
Hot water cylinder
A new 200–300L cylinder (£900–£1,400) is almost always required.
BUS grant
The Boiler Upgrade Scheme pays £7,500 toward your install — applied directly, no forms for you.
Insulation standard
Better insulation = smaller pump = cheaper install and lower run costs.
Groundworks (GSHP)
Ground-source needs trenches or a borehole — £8,000–£15,000 of the total cost.
How much does a heat pump cost in 2026?
An 8kW air-source heat pump for a 3-bed semi costs £11,500–£14,500 installed before grants. After the £7,500 Boiler Upgrade Scheme grant, you pay £4,000–£7,000.
Ground-source is roughly double the cost due to trenching or borehole work.
Will it save me money?
Compared to a gas boiler, a well-sized heat pump saves £300–£600/year on running costs when paired with a heat-pump-optimised tariff (Octopus Cosy, OVO Heat Pump Plus).
The real saving vs. oil or LPG is £900–£1,500/year.
Do I need new radiators?
Often yes. Heat pumps work at lower flow temperatures (45–55°C vs 70°C for a boiler), so radiators need to be larger to deliver the same heat. Your installer will do a full room-by-room heat loss survey first.
