UK Guide on Air Source Heat Pumps (2025 Edition)

Air source heat pumps (ASHPs) are revolutionising the way homes in the UK are heated and cooled, offering a range of benefits that make them an attractive choice for many households. These innovative systems are three to four times more efficient than traditional energy systems, such as gas boilers, and produce 2-3 times fewer CO2 emissions. This translates to significant reductions in carbon footprints and energy bills, with annual savings of up to £1,200 possible. ASHPs come in two types: air to air and air to water. Air to water heat pumps provide a comprehensive heating solution, supplying hot water for radiators, underfloor heating systems, and taps. On the other hand, air to air heat pumps transfer hot or cool air into homes using a fan system. The installation process for ASHPs is relatively straightforward, with monobloc heat pumps often being installed in just two days, causing minimal disruptions. Moreover, ASHPs are eligible for government-backed incentives like the Boiler Upgrade Scheme, which offers up to £7,500 towards installing an air source heat pump. ASHPs run on electricity, eliminating the need for high-combustion fuel types like gas, reducing the risk of accidents. They are also highly efficient, with efficiency rates of up to 400%, measured through the Coefficient of Performance (CoP), which ranges from 2 to 4.5. The primary benefits of an ASHP include environmental friendliness, versatility, cost-effectiveness, energy efficiency, and financial incentives. They are suitable for small and large households and operate efficiently even at temperatures as low as -10°C. Hybrid air source heat pumps combine a gas boiler with an ASHP for consistent heating and hot water supply. Another type of heat pump is the heat pump water heater, which serves a different purpose. ASHPs are more affordable than ground source heat pumps, which often have higher installation costs due to complex requirements. However, the cost of an ASHP depends on the heat pump brand, power output size, and installer. The cost of an air to water heat pump is between £9,000-£15,000, while air to air heat pumps typically cost between £4,000 and £9,500. ASHPs can provide heating, cooling, and hot water, making them a versatile solution for homes. They require low maintenance, with occasional checks every 2-3 years to ensure proper operation. With their long lifespan of 10-15 years, ASHPs offer a sustainable and cost-effective heating and cooling solution for the future. In addition to the Boiler Upgrade Scheme, there are multiple heat pump grants available in the UK, including the Energy Company Obligation (ECO4), Warmer Homes Scotland Scheme, Home Energy Scotland Scheme, Warm Homes Programme Wales, and VAT reduction. In conclusion, ASHPs offer a viable solution for homeowners looking to reduce their carbon footprint, lower energy bills, and enjoy the benefits of a modern, efficient, and versatile heating and cooling system.
