Frequently asked questions
Can I get a free ground source heat pump in L75 through the Warm Homes Plan?
Ground source heat pumps are available under the Warm Homes Plan for eligible L75 households, though they are less commonly funded than air source systems due to the installation requirements. Submit the eligibility form to find out whether your L75 property and circumstances qualify.
What is a ground source heat pump?
A ground source heat pump extracts heat from the ground via a network of buried pipes (ground loop), then uses that heat to warm your home and hot water. Ground temperatures remain stable year-round, making these systems highly efficient. They typically achieve a coefficient of performance (CoP) of 3 to 4.
What outdoor space is needed for a ground source heat pump?
Ground source heat pumps require either a horizontal ground loop buried in your garden (typically 200 to 400 square metres of land) or vertical boreholes drilled to depths of 50 to 150 metres. A free survey will assess whether your L75 property has suitable land or drilling access.
Who qualifies for a free ground source heat pump under the Warm Homes Plan?
Eligibility requires a qualifying means-tested benefit (such as Universal Credit, Pension Credit, or similar) and an EPC rating of D, E, F or G. The property must have suitable ground conditions. Owner-occupiers and private tenants with landlord permission can both apply.
Is a ground source or air source heat pump better for my L75 property?
Ground source heat pumps are generally more efficient but more expensive to install due to groundworks. Air source heat pumps are easier to fit on most properties. An installer will assess your specific L75 home during the free survey and recommend the most appropriate system based on your land, property type, and heating requirements.
Is the Warm Homes Plan still taking applications in L75?
Yes. The Warm Homes Plan is a long-running government programme with no announced end date. The L75 eligibility form takes 60 seconds to complete. Submit it now to find out what your property qualifies for.
