What is an air source heat pump?
A heat pump is essentially an outside boiler. It captures heat from outside and moves it into your home, using electricity to do so. Read more about how an air source heat pump works in our guide.
There are many benefits to heating your home with an air source heat pump, such as:
- high efficiency – an air source heat pump can be over 300% more efficient than a standard gas boiler, potentially saving you money on your heating bills(1)
- lower your carbon footprint by around 12% a year, that's roughly a return flight from London to Perth!(2)
- enjoy reliable heating and hot water all year round – an air source heat pump can still work effectively at -25°C!
- low maintenance with a long service life – (15+ years)
- government funding – you're likely to be eligible for a £7,500 grant from the government

Is an air source heat pump the right option for me?
Most homes are suitable for a heat pump. However, some updates to the property might be required to make sure the heat pump works effectively, such as updates to insulation, changes to radiators or even to the piping.
Our installers will never install a heat pump that won't keep your home comfortably warm. So you can have trust you're getting the best installation for your home.
To install a heat pump, you'll also need to meet all the requirements below:
- you need to be a homeowner
- your home needs to have enough outside space (approx 2m x 1m) and not within 1m of boundary walls
- space for a water tank (for the most carbon-efficient heat pump)
- your home needs to have good insulation, such as cavity wall and loft insulation

Air source heat pump FAQs
Will a heat pump lower my energy bills?
There are many factors that contribute to whether you’ll be able to save money on your energy bills, such as:
- your electricity tariff
- the type of heat pump you install
- the design of your central heating system
- your location and its average air or ground temperatures throughout the year
Savings on your energy bill will also depend on the system you're replacing. According to Energy Saving trust, if you are replacing an old (G-rated) gas boiler with an air source heat pump, you could save you up to £340(3).
Can a heat pump work in cold temperatures?
Heat pumps work more efficiently when it’s warmer which means they’ll have to work a bit harder when it’s cold. However, the heat pumps we can offer still work effectively at -25°C.
How long does it take to install a heat pump?
The heat pump that's installed is bespoke to your home. After speaking with a specialist and designing the right heat pump for you, it will take around 3-5 days to install. To read more about air source heat pump installations, visit our installation guide.
Will I need to replace my radiators?
In some cases, we’ll recommend installing larger radiators. If you have old or single panel radiators, you may need to replace your radiators for double or triple panel radiators to increase the surface area. Radiator upgrades are important as they’ll improve the efficiency of your heat pump and reduce running costs.
Are heat pumps noisy?
You can expect the noise to be a similar volume to a fridge. As it gets colder outside, this noise will increase while it’s operating. However, you shouldn’t be able to hear the sound indoors.
How long is the warranty for an air source heat pump?
All of our heat pumps come with a manufacturer's warranty of up to 7 years.
