The cost of an air source heat pump

So, how much are heat pumps in the UK? 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 pump prices in the UK are quite low, as ground source heat pumps cost between £16,200 and £49,000 including installation. Hybrid systems or high temperature air source heat pumps also tend to cost considerably more.

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:

How much is an air source heat pump?
Household size Technology type Heat pump size Average cost
1 bedroom Air to Air Heat Pump 3kW £2,400 - £6,200
1 bedroom Air to Water Heat Pump 8kW £8,400 - £11,150
2-3 bedrooms Air to Air Heat Pump 4-5kW £6,200 - £8,400

As you can see, the cost of heat pumps in the UK is relatively high compared to other systems. 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 up to £7,500 that will be deducted from the total costs you pay to your installer.

There are also other grants but they can be regionally-dependent. For example, the Warm Homes Programme can decrease the standard air source heat pump cost in Wales for all households. Other grants like Warmer Homes Scotland caters to those struggling with energy bills.

The running costs of an air source heat pump

Compared to traditional heating systems, air source heat pumps generally 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 you’re wondering “how much does air source heating cost?”, the table below can help answer that for different home sizes:

Cost of running a heat pump
Household Size Estimated Annual Energy Demand Estimated Annual Running Costs
1 bedroom 8,000 kWh £750

​​Air source heat pump installation costs

Currently, an air source heat pump installation costs anywhere from £3,500 to £6,000, excluding materials and the heating system. Exactly how much you will spend depends on the kind of air source heat pump you will be installing, the complexity of the installation, the size of your home, and the labour costs of the installer you work with.

Air source heat pump installation costs
Type of property Duration Installation cost (average)
2 bedroom semi-detached 2-3 days £3,500 - £4,500
3 bedroom semi-detached
Installation
3 days £4200 - £6,500
5 bedroom detached 3-5 days £6,000 or higher

Typically, an air source heat pump installation takes between 2 to 5 days to complete. Sometimes this can be shorter but often extra time is needed to finish the wiring and system commissioning. Ductwork can cost roughly £10 to £30 per foot (per 0.35 metres).

The more complex the installation, the more time the installer will have to spend working on your home, resulting in you having to spend more on labour costs. Factors that complicate air source heat pump installation include the size of the property, how old the infrastructure is, accessibility, and whether it needs more complex pipework, underfloor heating, an air to water unit, or other add-ons.

Savings with an air source heat pump

While the cost of air source heat pump installations can be high, in time, your investment will pay off. Below you can find an overview of the savings you can expect after having installed an air source heat pump for your home:

Air source heat pump savings
Energy System Being Replaced Estimated Savings
Gas boiler (A-rated) -£20
Gas boiler (G-rated) £240
Old oil boiler £410
Old LPG boiler £750
Old electric storage heaters £1,000
New electric storage heaters £600

These costs are estimates. Get a local installer QUOTE now!

As you can see, savings with an air source heat pump will vary significantly depending on the energy system you’re replacing. Considering that gas boilers are the most popular heating source in the UK today, the average break-even point for replacing a gas boiler with an air to air heat pump is about 17 years.

Good to Know

The exact duration of your return on investment period for installing an air source heat pump can fluctuate significantly, as it depends on current energy prices, the quality of your home’s insulation, as well as the size of the heat pump you are having installed.

To make the most of your savings, you will want to avoid overspending on your new air source heat pump. The surest way to keep your air source heat pump cost as low as possible is to compare multiple prices listed by different suppliers and installers. However, doing this on your own can take days of research if done alone.

What determines air source heat pump costs?

Several factors influence how much heat pumps in the UK cost. These include:

  1. The type of heat pump: An air to air heat pump will cost less than an air to water heat pump, with the former costing £2,400 to £8,800 and the latter priced between £8,750 to £14,050. 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): 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.
  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 for 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. These are a great way to mitigate heat pump costs in the UK if you are eligible.
  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?

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

If you are looking to lower your yearly electricity 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 if an air source heat pump is the right fit for your home. You should consider questions like: "Are heat pumps noisy?" and "Can an air source heat pump tend to my energy needs?" before making your investment. 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.

When determining how much are heat pumps going to benefit your home, you should consider whether the efficiency trumps the level of gas prices you pay with a boiler. This can be impacted by the quality of insulation and extreme temperatures. These factors need to be compared to the final air source heat pump price which can be between £2,400 to £8,800 for an air to air model and £8,750 to £14,050 for an air to water model. Another factor to consider is whether you can obtain a grant in your region.

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. It can be overwhelming to look through all the companies in an attempt to find the lowest air source heat pump price but it’s best to obtain multiple quotes from reputable sources before you decide to install one.
