FAQ
Prices for both Ground and Air source heat pumps vary depending on the size of the building and how well insulated it is. However, ball park numbers are:
- Air Source- Cost per kW £1,200
- Horizontal Ground Source- Cost per kW £2,000
- Drilled Ground Source- Cost per kW £2,700
Horizontal Ground Source Heat Pump: Generally for a new build property you need 4x the footprint of the building.
Vertical (Drilled) Ground Source Heat Pump: This is dependent on the number of boreholes required. Each borehole needs to be around 8m apart from the previous one.

When installing a heat pump the design of the whole heating system is vital. This includes sizing the internal emitter system as well as the heat pump correctly. As long as these elements are designed and installed correctly you will have a warm home ands as much hot water as your require at any temperature.
The main elements to consider if looking to retrofit a heat pump into an existing building:
- Amount of land available for GSHP
- Specific geology of the land
- Existing internal emitter system and if this needs upgrading
- Existing electrical infrastructure
- Existing and future use of building
Heat Pumps are powered by electricity. therefore the answer to the running costs depends on how much you pay for a kW of electricity.
Ground source heat pumps are the most efficient type of heat pump and a well installed system will give you between 4-5 kW of heat per kW of electricity.
Air source heat pumps will provide between 2.5-3.5 kW of heat per kW of electricity.
As part of our MCS accreditation at quote stage we are required to provide approximate run costs in comparison to your existing fuel.
