Heat Pump Installers in the UK
A heat pump instead of the boiler that is on its last legs, the £7,500 grant claimed by the installer, radiators sized so the house is actually warm, a system designed from a proper heat loss survey rather than a guess, a ground source loop in the field, or an honest answer about whether your house is ready: find a local heat pump installer people trust.

Finding a good heat pump installer in the UK
A heat pump heats a house by moving heat from the air or the ground into the water in the radiators, underfloor heating and the hot water cylinder, using a unit of electricity to deliver three or four units of heat; an air source heat pump sits outside like a large air-conditioning unit, a ground source system buries pipes in trenches or boreholes, and both replace a gas or oil boiler with a system that runs at lower temperatures for longer. Done well, on a house with reasonable insulation and radiators sized for it, a heat pump costs about the same to run as gas and much less than oil or LPG, with the government grant covering a large part of the install.
Choosing well is about the design, because a heat pump is only as good as its heat loss survey: a good installer measures every room, sizes the pump and the radiators to run at 45 degrees or lower, fits a cylinder and the controls, and commissions and explains it; a bad one fits an undersized pump to the old radiators and the house is cold and the bills high. The installer must be MCS certified for the grant, which they claim on your behalf, and the quote should show the heat loss, the pump model and output, the radiators changed, the cylinder, the electrics and the warranties. Planning is rarely needed, noise limits apply at the boundary, and the smart tariffs for heat pumps cut running costs further.
The listings here show each installer's MCS status, air and ground source systems, heat loss surveys, grants handled, prices and contact details, so you can see who is nearby, who designs properly, and whose heat pumps homeowners in your town are warm with a winter later.
What heat pump installers do
Air source: room-by-room heat loss survey, system design, the outdoor unit, cylinder and controls, radiator upgrades, installation, commissioning, MCS certificate and the grant claim.
Ground source: trenches or boreholes with the ground loop, the indoor unit and cylinder, and the higher efficiency for larger houses with land.
Air to air: the wall-mounted units that heat and cool rooms directly, without radiators, for flats, extensions and homes without a wet system.
The rest of the system: larger radiators, underfloor heating, hot water cylinders, buffer tanks, pipework, electrical upgrades, and removal of the boiler and oil tank.
Hybrids and commercial: heat pumps alongside an existing boiler, systems for new builds and retrofits, and commercial and multi-dwelling installs.
Before you commit to a heat pump
- Check the installer is MCS certified and in a consumer code; the grant and the warranties depend on it.
- Insist on a room-by-room heat loss survey, and ask what flow temperature the system is designed to run at; 45 degrees or lower is the target.
- Ask which radiators will be changed and why; undersized radiators are the commonest cause of a cold house.
- Sort the insulation first — loft, cavity, draughts — where it is cheap; it shrinks the pump and the bills.
- Get two or three quotes with the heat loss, the pump model, the cylinder, the electrics and the warranties itemised.
- Ask about noise at the boundary, the outdoor unit's position and the planning rules; the installer handles the permitted development check.
What heat pumps cost in the UK
As a rough guide, an air source heat pump installed costs £10,000 to £16,000 before the grant, including the unit, cylinder, controls, commissioning and typical radiator changes, so £2,500 to £8,500 after the £7,500 grant in England and Wales, with Scotland's grant and loan similar; ground source £18,000 to £35,000 before the grant depending on trenches or boreholes; air to air units £1,500 to £3,000 a room; extensive radiator or pipework changes add £1,000 to £4,000 and an electrical upgrade £500 to £1,500. Running costs on a well-designed system are similar to gas at standard tariffs and 20 to 40 per cent lower on a heat pump tariff, and half the cost of oil or LPG; heat pumps carry seven to ten-year warranties and last twenty years or more.
The £12,000 heat pump costs £4,500 after the grant, about what a new oil boiler and tank cost, and then runs for half the price of the oil.
Heat Pump Installers — frequently asked questions
Still unsure? See our plans →
How do I find a heat pump installer near me?+
Look at the installers listed for your town, check MCS certification, ask how they do their heat loss surveys and what flow temperature they design to, and read reviews from a winter or two after the install; get two or three itemised quotes. A local heating engineer with the MCS qualification is often better than a national sales operation.
How much does a heat pump cost to install?+
Typically £10,000 to £16,000 for an air source heat pump with cylinder, controls and radiator changes, so £2,500 to £8,500 after the £7,500 grant, and £18,000 to £35,000 for ground source before the grant; extensive radiator, pipework or electrical work adds £1,000 to £5,000. Quotes should itemise the heat loss, the pump, the cylinder and the changes.
What is the heat pump grant?+
The Boiler Upgrade Scheme in England and Wales pays £7,500 towards an air or ground source heat pump replacing a fossil fuel boiler in a home with a valid EPC, claimed by the MCS-certified installer and taken off the quote; Scotland offers a grant and interest-free loan through Home Energy Scotland. Insulation recommendations on the EPC no longer block the grant.
Will a heat pump keep my house warm?+
Yes, if it is designed properly: sized from a room-by-room heat loss survey, with radiators or underfloor heating big enough to heat the house at a flow temperature of 45 degrees or lower, and run steadily rather than switched on and off. Cold houses come from undersized pumps, old radiators and boiler habits, not from the technology; reasonable insulation helps but a fully insulated house is not required.
Are heat pumps cheaper to run than gas?+
About the same on a standard electricity tariff for a well-designed system with a seasonal efficiency of three or more, and 20 to 40 per cent cheaper on the heat pump and time-of-use tariffs; against oil, LPG or electric heating they save hundreds a year. A poorly designed system running at high temperatures costs more than gas, which is why the design and the installer matter.
Do I need planning permission for a heat pump?+
Usually not: air source heat pumps are permitted development on most houses if the unit is under a set size, meets the noise limit at the neighbour's nearest window and is not on a listed building or, in conservation areas, on a wall facing the road; the installer checks the noise calculation. Ground source needs no permission for the loop, and boreholes may need a licence.
