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's many benefits to heating your home with a heat pump, such as:

  • high efficiency – a heat pump can be over 300% more efficient than a standard gas boiler, potentially saving you money on your heating bills(2)
  • lower your carbon footprint by around 13% a year(3)
  • produce heat even when it's -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

How much does an air source heat pump cost?

Government grants are available to help cover costs, so installing an air source heat pump typically ranges from £4,100(1)(Price assumes reuse of a suitable existing hot water cylinder. Homes requiring a new cylinder will have an additional cost) to over £10,000. We also have finance packages available, which means you can spread the cost over manageable monthly payments.

Grants for air source heat pumps

Now's the perfect time to take advantage of government grants and switch to a low carbon heating system.

We can help you apply for the right government scheme that provides either £7,500 or £9,000 for some rural areas in Scotland towards the cost of your heat pump.

  • you own your property (whether this is your home, a holiday let or small commercial property)
  • you’re replacing the old fossil fuel or electric heating system with a renewable heating system such as a heat pump

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 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) 
  • space for a water tank (for the most carbon-efficient heat pump)
  • your home needs to have cavity wall and loft insulation

We'll install low-carbon heat pumps made by Ideal Heating, a brand with over 100 years of heating innovation and expertise under their belt. They install high-quality heat pumps in homes across the country, helping homeowners lower their carbon footprint.

Air source heat pump FAQs

There are many factors that contribute to whether you’ll be able to save money on your energy bills, such as:

  • your electricity tariff - we have a range of heat pump tariffs that all offer twice daily discounts
  • 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

Your energy bill savings will also depend on the system you're replacing. According to Energy Saving Trust, replacing an old (G-rated) gas boiler with an air-source heat pump could currently save you up to £290(5).

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.

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.

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.

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.

All of our heat pumps come with a manufacturer's warranty of up to 7 years.
