Air source heat pumps are an increasingly popular choice for UK homeowners wanting to cut their energy bills and reduce carbon emissions.
Home heat pump installations rose 50% in 2024 compared to 2023, and many are considering if it’s the right time to switch from gas, weighing up the upfront cost of a heat pump against the potential savings.
Advantages of a Heat Pump
1. Lower Energy Bills
Heat pumps are highly efficient—producing 3–4 units of heat for every unit of electricity used. Put simply, you’ll only pay for a third or quarter of the heat your home uses. Heat pumps use 100% electricity, and no gas. This nearly always means lower bills than with gas or oil boilers, and no more gas bills to pay!
2. Environmentally Friendly
Heat pumps reduce carbon emissions by replacing gas boilers and use electricity that’s increasingly from renewables. Pairing with solar panels can make your heating nearly carbon neutral, so a great choice for people who want to switch to environmentally friendly living.
3. Government Incentives
In 2025, the Boiler Upgrade Scheme offers £7,500 grants for UK homeowners. At Carters, you don’t have to worry about any of the paperwork or application, this is all handled for you, and you’ll be provided a heating survey which is fully costed. It’s a long-term investment that improves efficiency and comfort, as well as adding value and appeal to your home.
4. Low Maintenance & Long Lifespan
It’s really important an air source heat pump is installed and set up properly by experts. It will then need minimal upkeep, your heating will be reliable in UK temperatures, and typically it will last 20 years or more. Today’s heat pumps are much quieter than older models, and we will set it up so you can easily control your heating through an app on your phone and digital thermostat.
Disadvantages of Heat Pumps
1. Upfront Cost
Heat pumps are ‘new’ technology compared to old gas boilers which they replace, and installation is more expensive, although you’ll get £7,500 towards the cost. Some homes need extra insulation or new radiators. At Carters Plumbing and Heating we will provide you with an initial, free quote. If you want to proceed we’ll then arrange a full home heating survey which will show you in detail what your home needs and the cost.
2. Efficiency in Extreme Cold
Modern pumps work well in low temperatures, but efficiency may dip in extreme cold—rarely an issue in southern England.
3. Outdoor Space
The external unit needs space, which may be a challenge for smaller properties or flats. Proper installation by experts is essential - we get asked to fix many badly installed heat pumps!
4. Noise & Appearance
Heat pumps emit a quiet hum from the fan. Some people find them unattractive, though they're quieter and more compact than older models.
In Summary
Heat pumps offer energy savings, comfort, and eco benefits when installed by a fully qualified expert—making them a smart long-term choice. However, not all homes are ready without modifications.
