Overview
Why ground source heat pumps?
A ground source heat pump collects heat from pipes buried in your garden — in trenches or boreholes — where the temperature stays steady all year.
It's the most efficient type of heat pump for larger homes and rural properties with land, and qualifies for the same £7,500 Boiler Upgrade Scheme grant for eligible homes.
Steady ground temperature
Heat from the ground, which stays stable through the year.
£7,500 grant
Boiler Upgrade Scheme for eligible homes in England and Wales.
No outdoor fan unit
The collector is buried; the heat pump sits indoors.
0% VAT
Zero-rated for homes until 31 March 2027.

Planning, regulations and timings
Room-by-room heat loss survey
An MCS heat pump design starts with a room-by-room heat loss calculation (BS EN 12831) to size the heat pump and every radiator. Our heat loss survey costs £250–£650 depending on property size, and the fee is credited against your installation if you go ahead within 90 days.
Land and access
Trenches need garden space; boreholes need access for a drilling rig. Both are assessed at survey.
0% VAT
Solar panels, batteries and heat pumps installed in homes in Great Britain are zero-rated for VAT until 31 March 2027.
Annual servicing
Every installation can go on an annual service plan, so it keeps running efficiently and stays within any manufacturer servicing conditions. Plans and prices are confirmed on request.
Questions
Ground source heat pumps: your questions answered
How much does a ground source heat pump cost?
£20,000–£35,000 installed, before the £7,500 Boiler Upgrade Scheme grant. Indicative, supplied and installed in London and the South East, including VAT; prices updated 11 October 2026. A survey confirms the final figure.
How much land do I need for ground source?
It depends on your home's heat loss. Horizontal trenches need a reasonable area of garden; boreholes need much less space but cost more to drill.
Ground source or air source?
Ground source is more efficient but costs more to install (£20,000–£35,000 against £10,000–£16,000 for air source). Air source suits most homes; ground source suits larger homes with land.
