Heat pumps for Cardiff homes
The Boiler Upgrade Scheme applies in Wales just as in England, so Cardiff homeowners can claim the same £7,500 grant. Lower-income households may also qualify for a fully funded installation through the Welsh Government's Nest scheme.
Local tip: Cardiff's terraces often have narrow rear lanes and yards. A compact, wall-mounted unit can solve tight siting.
Why choose an air source heat pump in Cardiff?
- Renewable heating: it takes free heat from the air. It cuts heating emissions by about 70% compared with gas.
- High-efficiency heating: modern heat pump systems give 3 to 4 units of heat for each unit of electricity. A gas boiler gives about 0.9.
- Radiators and hot water: it heats your radiators (or underfloor heating) and a hot water cylinder. It replaces your boiler completely.
- Lower bills off the gas grid: homes on oil, LPG or storage heaters save the most.
- Smaller carbon footprint and lower energy bills: renewable energy from the air replaces fossil fuel. Efficient heat means you buy less energy.
- Works with solar panels: a solar panel system can power your heat pump in the day.
- A long life: around 20 years with an annual service.
Air source is the best renewables heating choice for most Cardiff homes. Ground source heat pumps suit homes with lots of land. They cost far more to fit; see ground source vs air source.
The £7,500 Boiler Upgrade Scheme (BUS) grant in Cardiff
Homeowners, landlords and small businesses in Cardiff can get a £7,500 government grant. It comes from the Boiler Upgrade Scheme (BUS). It is not means-tested. Your installer applies for you and takes it off your quote. Heat pumps also have 0% VAT until 31 March 2027. You are likely to qualify if:

- the property has a valid Energy Performance Certificate;
- the heat pump is installed by an MCS-certified installer.

How heat pumps perform in Cardiff's climate
South Wales has mild but wet winters. Heat pumps cope well, and siting the unit so meltwater and rain drain away freely keeps the system running smoothly. Heat pumps work down to about -20°C. A Cardiff winter is well within that. Read more: do air source heat pumps work in winter?
