Heating from the ground beneath your home
A ground source heat pump gives homeowners the chance to switch to one of the most efficient heating technologies available. Unlike boilers that burn gas or oil, ground source heat pumps (GSHPs) capture natural warmth from the ground and transfer it into your home. It can be used for central heating and hot water, and works especially well with underfloor heating, offering long-term savings and comfortable, low-carbon heat.
How a GSHP works
A network of underground pipes, known as a ground loop, is laid horizontally in trenches or vertically in boreholes. A fluid circulates through the loop, absorbing heat from the ground, which stays at a fairly steady temperature all year. The heat pump concentrates this energy and delivers it to your heating system. Because the ground temperature is stable, the system stays efficient through winter.
Survey, design and installation
The process begins with a professional site assessment. Installers survey your property, calculate room-by-room heat loss and decide whether a horizontal or vertical loop suits your land. They then manage trenching or drilling, equipment installation and commissioning, making sure the work meets UK energy and building regulations. GSHPs can be connected to underfloor heating or correctly sized radiators for efficiency and comfort; some radiators may need upgrading to work well at lower flow temperatures.
Electrical work and notifications
A heat pump needs a dedicated electrical supply. The electrician checks your main fuse and maximum demand, adds the circuit and protection, and tests the work to BS 7671:2018+A4:2026, the current IET Wiring Regulations. A new circuit is notifiable under Part P in England, so you should receive an Electrical Installation Certificate (EIC) and a Building Regulations compliance certificate. Your installer must also notify your distribution network operator about the heat pump, or apply first if it would take the property's demand over the threshold. Boreholes may need notifying or other permissions depending on depth and location; your installer will advise.
Costs and grants
With efficiency levels up to 400 percent, homeowners can expect noticeable reductions in energy bills over time. In England and Wales, the Boiler Upgrade Scheme offers £7,500 towards a ground source heat pump when you replace fossil fuel heating, plus an extra £1,500 until March 2027 if your home is heated by oil or LPG and has no mains gas connection. Your installer applies for the grant, and the heat pump must be installed and commissioned within 120 days of the application. Beyond savings, a GSHP increases your home's energy independence and protects against fluctuating fuel prices.
Maintenance requirements are minimal, and ground loops are designed to last for decades with only occasional servicing of the heat pump. Choosing a ground source heat pump also lowers carbon emissions, helping households contribute positively to environmental goals.
