What is a Ground Source Heat Pumps
A ground source heat pump is a renewable heating system that extracts low-temperature solar energy stored in the ground or water using buried pipework and compresses this energy into a higher temperature. A ground source heat pump provides a building with 100% of its heating and hot water all year round.

Are Ground Source Heat Pumps More Efficient Than Air Source Heat Pumps?
Yes, ground source heat pumps are more efficient than air source heat pumps. The ground temperature in the UK typically remains between 8℃ – 12℃, whereas the air temperature in winter especially during the mornings and evenings when heating is required, is often much cooler. Extracting heat from the ground is more efficient than extracting heat from the air during these times.
How Much Do Ground Source Heat Pumps Cost?
The cost of Ground source heat pumps typically range from £3,500 – £6,000. Installation costs are often higher than alternative heating systems, but when compared over a product lifetime, ground source heat pumps are more cost-effective and carbon-efficient than alternative heating systems.
Zero Rated VAT on Heat Pumps
You could be eligible for a 0% VAT rate for domestic purchases of heat pumps. 0% VAT is available to homeowners until 31st March 2027. Full details can be found here.
How We Work
We are Ground Source Heat Pump installers. On completion, our ground loops are pressure tested before grouting to ensure their integrity. Connected pipework is likewise pressure tested and certificated before the addition of the heat transfer fluid, ready for connection to the ground source heat pump. We install Stiebel Eltron heat pumps which are exceptionally high quality.
All GSHP loops and connected pipework are installed with electro-fused couplers and materials to ensure the highest quality installation and compliance. We are able to install both closed and open loop systems.
Is a Ground Source Heat Pump Right For Me
There are a few things to consider when thinking about installing a ground source heat pump.
You can use the online assessment tool, Go Renewable, to find out what renewable technologies, like heat pumps, are suitable for your home.
You’ll need an area of land near your property where you can dig trenches or drill boreholes.
Here are a few questions you should ask yourself, please see the YouTube video to the left.
Digging Trenches For a Ground Loop
If you have the space, then you can have a ground loop system. The ground will need to be suitable for digging and accessible to machinery from a road entrance. The area will need to avoid trees, as roots will cause problems when digging trenches.
The length of ground loop and trenches depend on the size of your home and the amount of heat you need. For a newbuild three-bedroom house, you could expect two trenches of 30-40 metres in length, and more space required if your home is larger or an older property that isn’t as well insulated.
Boreholes
If space is limited, it may be possible to drill vertical boreholes to gather heat. This is usually more expensive than digging trenches and usually needs a specialist ground (thermogeological) survey. The ground is generally warmer the deeper you dig, so these systems can be more efficient than ground loop systems.
Larger houses may require more than one borehole. A borehole is drilled only about 20cm wide, but somewhere between 75 and 200 metres deep. The depth of the borehole depends on the heat demand of your home and the underlying geology.
