How much does an air source heat pump cost?

A typical air source heat pump installation costs £8,000–£14,000 before grants. With the £7,500 Boiler Upgrade Scheme grant, your out-of-pocket cost can be as low as £500–£6,500.

How much can I save with a heat pump?

Heat pumps can reduce heating costs by up to 50% compared to gas boilers. Savings depend on your current heating system, insulation levels, and electricity tariff.

Do heat pumps work in cold weather?

Yes, modern air source heat pumps operate efficiently down to -20°C. They extract heat from outdoor air even in freezing temperatures, making them suitable for UK winters.

Am I eligible for the £7,500 BUS grant?

You may qualify if your property is in England or Wales, you have a valid EPC with no outstanding loft or cavity wall insulation recommendations, and you're replacing a fossil fuel heating system.

How long does heat pump installation take?

A typical air source heat pump installation takes 2–4 days, depending on the complexity of the system and any radiator upgrades required.

How Heat Pumps Work

Efficient Heating from Outdoor Air

Heat pumps work like a fridge in reverse – extracting heat from outdoor air and amplifying it to heat your home and hot water.

Extract Heat

The heat pump extracts heat energy from the outside air, even in temperatures as low as -20°C.

Compress & Amplify

The refrigerant cycle compresses this energy to increase its temperature to usable levels.

Distribute Heat

Hot water is circulated through your radiators or underfloor heating to warm your home. See our radiator sizing for heat pumps guide.
