Heat Pump Type

Air Source Heat Pumps

The most popular heat pump option for UK homes — extracts heat from outdoor air to provide efficient heating and hot water, with up to £7,500 towards installation.

What Is an Air Source Heat Pump?

An air source heat pump (ASHP) absorbs heat from the outside air and uses it to heat your home and hot water. It works like a refrigerator in reverse — even when outdoor temperatures drop as low as -15°C, there is enough thermal energy in the air for the system to operate efficiently.

ASHPs are the most widely installed heat pump type in the UK. They are suitable for most property types, require minimal outdoor space, and can be fitted in as little as 2–3 days. With the Boiler Upgrade Scheme offering grants of up to £7,500, switching to an air source heat pump has never been more affordable.
