The cost of an air source heat pump

The supply cost of an air source heat pump ranges from £2,400 to £12,350. Air-to-air heat pumps are on the lower end of this price range, as they can only provide heating and cooling. Air-to-water heat pumps, on the other hand, can also be connected to your central heating system to supply your home with hot water. 

Compared to other heat pump options, air source heat pumps are a cost-effective solution, as ground source heat pumps cost more, between £13,200 and £49,000 including installation. The exact cost of an air source heat pump installation will vary depending on your situation. Below you can find the estimated cost of installing an air-to-air or air-to-water heat pump in an average household:

As you can see, the cost of heat pumps in the UK is relatively high. To lessen the financial burden of installing this renewable energy source for your home, you can apply for grants such as the Boiler Upgrade Scheme. This way, you can receive a grant of £7,500 that will be deducted from the total costs you pay to your installer. 

The running costs of an air source heat pump

Compared to traditional heating systems, air source heat pumps have low running costs. As a result, you’ll be able to avoid overspending on your energy bills in the long run.

To give you an indication of the cost of running a heat pump, we calculated the yearly running costs of an air source heat pump. Some of the factors we considered to determine the running costs of domestic heat pumps are the Coefficient of Performance (COP), the heating requirements of average households, and current energy costs in the UK.

  • If a separate heat source is used for domestic hot water heating, such as solar thermal panels

What determines the air source heat pump costs?

There are several factors that influence the total air source heat pump cost. These include:

Heat pump cost factors
  1. The type of heat pump: An air-to-air heat pump will cost less than an air-to-water heat pump. At the same time, the type of heat pump you choose will affect the installation cost, as the complexity of the installation may vary, requiring the installer to spend more time fitting your air source heat pump. 
  2. The Coefficient of Performance (COP) of the heat pump: The COP measures the efficiency of a heat pump and indicates the amount of power input compared to the amount of power output produced by the heat pump. Typically, the COP value of an air source heat pump is between 2.5 and 3.5. In most cases, efficiency will also influence the total cost of the air source heat pump. 
  3. The size of the heat pump: Measured in British thermal units (BTUs), heat pump size refers to its service capacity or its power. A heat pump will have around 12,000 BTUs per ton of size. However, the higher the power capacity of an air source heat pump, the higher the cost. So, make sure to calculate how much power you’d need your appliance to generate for your home. 
  4. Available incentives and grants: If you are eligible for heat pump grants, then you will be able to lessen the financial burden of investing in this energy system for your home. For instance, with the Boiler Upgrade Scheme, you can receive up to £7,500 to install an air source heat pump for your home. 
  5. Service or maintenance costs: The total cost of installing a heat pump will also include the labour costs your installer will charge. At the same time, on average, annual heat pump maintenance can cost around £100 – £200. While this may seem like a heavy expense, regular maintenance will spare you any big repairs and ensure that your heat pump continues to run optimally, which will save you money in the long run. 

Keeping these factors in mind when trying to determine how much an air source heat pump will cost you can help you avoid any surprises when it comes to your total expenses. So, when making your calculations, be sure to account for all these aspects of installing an air source heat pump for your home. 

Is an air source heat pump the right choice for my home?

If you are looking to lower your yearly energy bills and your carbon footprint, then an air source heat pump can be a great addition to your home. Because they generate energy using the air outside and transferring heat into your home, they require less fuel to operate than traditional heating systems. This has a positive impact on your bank account, as well as on the environment.

However, while it comes with these impressive advantages, you should carefully consider whether an air source heat pump is an investment you are ready to make. The cost to install a heat pump is quite high and the return on investment period is quite long. That said, if you are planning on making a long-term change to your energy system, an air source heat pump will pay off over time. 

To be able to reap the financial benefits of installing an air source heat pump, you will need to ensure that you are not overpaying for your new installation. In most cases, this is easier said than done. With so many installers to choose from, it can be overwhelming to look through all your options in an attempt to find the lowest air source heat pump cost.
