Ground Source Heat Pumps: Advantages and Disadvantages
- The biggest advantages of ground source heat pumps are their remarkable efficiency rating, reaching up to 400%, and their eligibility for government grants that can save homeowners up to £7,500 through the Boiler Upgrade Scheme.
- The primary disadvantage of ground source heat pumps is their significant upfront cost, which can range from £13,200 to £49,000 including installation costs.
- Ground source heat pumps’ lifespan is around 25 years, making them a worthwhile long-term investment, in addition to their efficiency and grant eligibility which can help offset initial costs.
Ground source heat pumps (GSHPs) are excellent low-carbon heating systems that are able to extract warmth from the ground by using buried pipework rather than producing it by burning fossil fuels.
In addition, once installed, ground source heat pumps can help you save up to £1,900 on your yearly energy bills, as they have low running costs. However, the initial price of a ground source heat pump is high, which can turn some homeowners away. That said, like other types of heat pumps, GSHPs are eligible for the Boiler Upgrade Scheme.
To help you determine whether a GSHP is the right choice for you, we will walk you through the ground source heat pump advantages and disadvantages in this comprehensive guide.
Before investing in a ground source heat pump, it is important to seek tailored guidance from industry professionals.

What is a heat pump and how does it work?
A ground source heat pump operates similarly to a refrigerator, transferring heat between spaces. While a fridge removes heat from the inside and releases it outside, a ground source heat pump extracts heat from the ground and can also provide cooling by reversing this process.
The temperature in the ground remains stable throughout the year, making GSHPs less susceptible to adverse weather conditions, in contrast to their air source heat pump counterparts. This ensures that you can enjoy consistent heating year-round.This heat is captured by underground pipes, further heated, and then distributed to your home’s central heating system for use in radiators, underfloor heating, and showers.
As you can see, this eco-friendly energy system is highly versatile, acting as both a heating and cooling system. However, it also comes with some drawbacks. In the coming sections, we will outline the ground source heat pumps’ pros and cons so you can consider them before making a final decision.
Ground source heat pump advantages
The following list comprises what we researched to be some of the most outstanding advantages of GSHP:
- Low running costs: GSHPs boast lower running costs compared to air source heat pump running costs and electric heating systems in general. Typically, annual GSHP running costs range from £525 to £1,185 on average.
- Energy efficient: Ground source heat pumps can reach outstanding efficiency ratings of up to 400%.
- Low carbon heating: This type of heat pump does not produce carbon emissions on site as they don’t use any fossil fuels. This makes it a great low carbon heating solution, especially if paired with solar panels that can generate renewable electricity for it to run on.
- Provides cooling and heating: Unlike air conditioners, heat pumps utilise a reversing valve to switch the fluid circulation direction for heating, eliminating the need for a separate furnace.
- Eligible for grants: Ground source heat pump grants, like the Boiler Upgrade Scheme, can save homeowners up to £7,500, reducing costs and making ground source heat pumps a more appealing investment.
- Constant and inexhaustible: Ground heat is usually constant and inexhaustible (there are almost no fluctuations in its capability for heating and cooling), is available worldwide and has a massive potential.
- Virtually silent: GSHPs operate underground, hence they are silent runners, so you or your neighbours will not be bothered by a noisy heat pump unit.
- Increases property value: A well-designed ground source heat pump installation can boost property value by 1.7% to 3%, making it a valuable home improvement option.
Ground source heat pump disadvantages
The list below shows the primary ground source heat pumps disadvantages:
- High installation costs: The main disadvantage of ground source heat pumps lies in their substantial initial expenses, which typically vary from £13,200 – £19,000. Including installation, costs can reach up to £49,000.
- Efficiency affected by soil type: While ground source heat pumps can be installed in sandy or clay soil, sandy soil may slightly reduce efficiency. Your installer will evaluate this and incorporate the required components to optimise efficiency for your property.
- Disruptive installation: Given their complex installation, GSHPs are more common for new-builds rather than for retrofits. If a property does not have a large enough garden, then a vertical ground source heat pump borehole can be installed instead, though this is more costly than a horizontal system.
Is a ground source heat pump the right choice for your home?
All in all, after considering the pros and cons of ground source heat pumps, it can safely be concluded that they are a valuable long-term investment for homeowners who are seeking to become more environmentally conscious.
GSHPs offer an impressive efficiency rating of up to 400%, boost property value by about 1.7% to 3%, and are eligible for government grants of up to £7,500, despite their significant upfront costs ranging from £13,200 to £49,000.
While better suited for new builds, GSHPs can also be a viable retrofit option, providing enhanced energy efficiency, reduced carbon footprint, and increased property value.
Of course, such a device requires a specialist to carry out the installation. The difficulties show up at the external part of the GSHP installation. It is necessary to excavate and distribute an extensive net of pipes (those that will take heat to or from the ground). Fortunately, this doesn’t generate major environmental issues.
However, you’ll need to look for a reliable GSHP installer.
