How much does an air source heat pump cost?

If you’re considering switching to an air source heat pump for your heating and hot water, the cost of your installation is going to be a consideration for you. Here’s what you need to know.

Air source heat pump costs

The cost of an air source heat pump

Air source heat pumps cost a lot less than ground source heat pumps and are much easier to install. On average, the cost of installation will range from £6,000 to £8,000, depending on the size of your home and the room temperatures you are looking to achieve. In contrast, a ground source heat pump will start from £10,000, and could cost a lot more if there is a lot of groundwork to be done.

There are other costs to consider if you’re thinking of switching to an air source heat pump, which could increase this estimate. Air source heat pumps are designed to deliver water at a lower temperature than the traditional combination of boiler and radiators. For example, air source heat pumps work very well with underfloor heating, but if you don’t already have this in your home then the installation of this will add to the cost. If you aren’t going for underfloor heating, you may need additional radiators, or to have your existing radiators replaced with larger models which will work with the lower temperature system to provide sufficient heat to your home. You may also need new heating controls, better insulation and other ‘extras’ that can all inflate the cost.

When you’re seeking quotes for your heat pump, make sure your installer has factored in all the bits and pieces you’re going to need in order to have an effective heating system, and avoid working with installers who try to mask the real price.

How much could you save?

The amount you could save by investing in an air source heat pump will vary depending on the type of heating it is replacing. To give you a guide, figures from the Energy Saving Trust suggested that the annual savings are as follows:

  • Replacing electric night storage heaters: From £735 to £820
  • Replacing a non-condensing gas boiler: £455 to £485
  • Replacing a non-condensing oil boiler: £290 – £315
  • Replacing a non-condensing LPG boiler: £1,000 – £1,090

If you already have a condensing gas or oil boiler, you could actually end up paying more to heat your home by changing to an ASHP, so make sure you do your calculations if cost is your main reason for installation. Of course, there is currently the Renewable Heat Incentive (RHI) to bring into the equation too, which would pay you an annual benefit of between £1,140 and £1,235 each year.

Getting a quote for your air source heat pump

Heat pump prices have a fair bit of variation, so it’s important to shop around to ensure you get a good price. You should always work with an experienced, certified installer, who is a member of the Microgeneration Certification Scheme (MCS). This will give you confidence in their work and is also a prerequisite of qualifying for the Renewable Heat Incentive. We recommend you obtain at least three quotes before deciding who to go with, to ensure you are getting a great value offer. Why not take a look at our database of MCS certified air source heat pump installers to find your local trusted supplier?
