Can You Get a Government Grant for Air Conditioning?

Summers in the UK have been getting hotter, and many families are wondering if the government will help pay for air conditioning in their homes. Right now, there is no direct government grant for a standard air conditioner or a portable cooling unit. However, homeowners in England and Wales can receive £2,500 toward a special device called an air-to-air heat pump through a program known as the Boiler Upgrade Scheme.

An air-to-air heat pump works like a reversible air-conditioning system. In winter, it pulls heat from the outdoor air and pushes warm air into the rooms inside. When summer arrives, it works in reverse — it removes heat from inside the home and releases it outside, which cools the rooms down. This means one system can both heat a home in winter and cool it in summer.

This type of heat pump is different from the more common air-to-water heat pump found in many UK homes. Air-to-water pumps connect to radiators and can also heat a home's water supply. Air-to-air pumps usually cannot do either of those things, so a household might still need a separate system just for hot water. They can be a good fit for homes that use electric storage heaters and don't have traditional radiators.

The £2,500 grant from the Boiler Upgrade Scheme is meant to help replace an old heating system with a cleaner, low-carbon option. It is not simply a discount for adding a cool-air unit to one room of a house. The heat pump must be able to handle all of the home's heating needs on its own. It also must replace an existing gas, oil, or electric heating system rather than just work alongside it.

This means a homeowner could not keep their old gas boiler, add a single wall-mounted air conditioner to one room, and use the grant to pay for it. Hybrid systems that mix a heat pump with a fossil-fuel boiler are also not allowed under the scheme. The grant is only available for homes that people live in, and most brand-new homes and social housing do not qualify.

The installation must be done by a certified professional. Installers must be approved under a program called the Microgeneration Certification Scheme, or MCS. Homeowners do not apply for the grant themselves — the certified installer applies to the energy regulator Ofgem for a voucher, and that amount is then taken off the homeowner's bill.

Experts recommend getting quotes from several installers before agreeing to any work. It is also important to ask each installer to confirm that the system will qualify for the grant before paying a large deposit. Air-to-air heat pumps only recently became eligible for this grant, so not every installer may be taking part in the scheme yet.

An air-to-air heat pump could be a smart choice for the right home, especially as UK summers grow warmer. The £2,500 grant can meaningfully reduce the upfront cost. But homeowners should think carefully about all their needs — including hot water, where the units will be placed, and how much electricity cooling might use — before making a decision based only on staying cool during the next heatwave.
