Cost of ground source heat pumps in the UK
Ground source heat pump costs range from £16,200 - £49,000. Compared to air source heat pump costs, the prices are higher, both in terms of supply and installation. However, as we will discuss later as well, the savings with a GSHP are also significantly higher.
The primary factors that affect the total costs of a ground source heat pump are the output size and type of heat pump installation you choose. Below you can find an overview of the costs of a horizontal and vertical ground source heat pump installation for different output sizes:
| Household Size | Heat Pump Output Size | Estimated Supply Cost | Estimated Installation Cost | Estimated Total Cost |
|---|---|---|---|---|
| 1 bedroom | 8kW | £13,200 | £3,000 | £16,200 |
| 2-3 bedrooms | 12kW | £14,850 | £7,500 | £22,350 |
| 4+ bedrooms | 16kW | £19,000 | £12,000 | £31,000 |
| Household Size | Heat Pump Output Size | Estimated Supply Cost | Estimated Installation Cost | Estimated Total Cost |
|---|---|---|---|---|
| 1 bedroom | 8kW | £13,200 | £10,000 | £23,000 |
| 2-3 bedrooms | 12kW | £14,850 | £20,000 | £34,850 |
| 4+ bedrooms | 16kW | £19,000 | £30,000 | £49,000 |
Ground source heat pump running costs
One of the primary advantages of heat pumps is that they involve reduced running costs compared to old heating systems. Here is a rundown of the annual running costs of GSHPs of different output sizes:
| Household Size | Heat Pump Output Size | Estimated Yearly Running Costs |
|---|---|---|
| 1 bedroom | 8kW | £740 - £615 |
| 2-3 bedrooms | 12kW | £930 - £905 |
| 4+ bedrooms | 16kW | £1,405 - £1,270 |
Ground source heat pump installation cost
The cost of a ground source heat pump is heavily influenced by the kind of installation you opt for. As we’ve mentioned, horizontal groundwork costs less than a vertical installation.
This is because a horizontal GSHP installation also requires between 1 - 3 boreholes in order to reach deep into the ground so that your heat pump can extract geothermal energy. Below you can find an indication of how much a vertical ground source heat pump costs.
| Heat Pump Output Size | Number of Boreholes Required | Estimated Borehole Costs | Estimated Total Installation Costs |
|---|---|---|---|
| 8kW | 1 - 2 | £8,000 - £10,000 | £10,000 |
| 12kW | 2 | £12,000 - £18,000 | £20,000 |
| 16kW | 2 - 3 | £16,000 - £24,000 | £30,000 |
A horizontal GSHP installation, on the other hand, is slightly less complex, as it only needs trenches that are about 1.2 metres deep. The larger your heat pump, the higher the cost of your installation will be, as you’ll be paying for the digging per square metre.
Below, we’ve provided some estimates of the cost of ground source heat pump installation if you opt for horizontal groundwork:
| Heat Pump Output Size | Estimated Trench Space Required | Estimated Groundwork Costs | Estimated Total Installation Costs |
|---|---|---|---|
| 8kW | 300 metres | £3,000 | £3,000 |
| 12kW | 500 metres | £5,000 | £7,500 |
| 16kW | 650 metres | £6,500 | £12,000 |
While a horizontal installation is a cheaper option, it’s important to note that they take up significantly more space than vertical groundwork. So, be sure to consider this aspect, as well as your budget, when trying to calculate the cost to install a ground source heat pump.

Ground source heat pump maintenance costs
Ground source heat pump maintenance costs range somewhere between £200 and £350. Fortunately, you only need to have your heat pump serviced once every 2 - 3 years.
This way, you can ensure that your ground source heat pump can operate efficiently for the duration of its 25-year lifespan. Additionally, regular maintenance helps you avoid mounting repair costs, as any damage can be addressed immediately when a professional is servicing your system.
Equipment vs non-equipment costs
The total ground source heat pump cost can be broken down into equipment and non-equipment costs. Generally, the equipment costs of a ground source heat pump are higher than non-equipment.
However, depending on the output size of your heat pump, the non-equipment costs of a vertical installation will be higher. The equipment costs of a 12kW and 16kW heat pump are £14,850 and £19,000, respectively. The non-equipment costs, however, are £20,000 and £30,000.
Below, you can find a breakdown of the different components that contribute to the total equipment and non-equipment costs of a ground source heat pump:
Ground source heat pump savings
Once you install a ground source heat pump, you will start noticing savings ranging from £90 to £2,000 on your yearly heating bills. Exactly how much you’ll save depends on your household’s energy consumption habits and on what kind of heating system you’re replacing with a ground source heat pump.
You can consult the following table for an indication of the savings you can expect when switching from traditional energy systems to a ground source heat pump:
| Energy System Being Replaced | Estimated Yearly Savings |
|---|---|
| Gas boiler (A-rated) | Up to £90 |
| Gas boiler (G-rated) | Up to £550 |
| Old (G-rated) oil boiler | Up to £600 |
| Old LPG boiler | Up to £1,100 |
| Old electric storage heaters | Up to £2,000 |
| New electric storage heaters | Up to £1,200 |
As you can see, the highest savings come from replacing old electric storage heaters with a ground source heat pump. If this applies to you, take a look below to see what you can expect in terms of breaking even on your investment in a GSHP:
| GSHP Installation Type | Estimated Total Installation Costs | Estimated Savings from Replacing Old Electric Storage Heaters | Break-Even Point |
|---|---|---|---|
| Horizontal groundwork | £16,200 - £31,000 | Up to £2,000 | 8.5 - 16 years |
| Vertical groundwork | £23,000 - £49,000 | Up to £2,000 | 12 - 25.5 years |
Considering that ground source heat pumps can operate efficiently for about 25 years, you can still enjoy all the financial benefits that come with this heating system for years after you’ve broken even on your investment. That is, if your annual savings are this high.
If you expect that your installation costs will be at the higher end of the price range and your savings might be lower, be sure to make some calculations to determine when you’ll break even on your investment. You should also consult a professional who can offer you tailored advice to help you decide whether it’s worth installing a ground source heat pump for your home.
