How we handle air source heat pumps in Great Kingshill
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes, and the quote sets it out. Common call-outs are for not knowing whether a grant applies and working out where a cylinder could go, across underfloor heating, homes heated by oil, LPG or gas and hot water cylinders.
Space for an outdoor unit is rarely an issue near Great Kingshill, so the design comes down to heat loss, radiators and hot water.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Looking after it afterwards
Simple habits make a real difference. Our advice:
- Let the heat pump run steadily, as set up at handover
- Check what your manufacturer’s warranty asks of you
- File the MCS certificate safely
We show you how to use the controls and explain how a heat pump works differently from a boiler. Heat pumps tend to work best running steadily rather than in short bursts so we set the controls up with you.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
What the work involves, system by system
VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote.
Air-to-water heat pumps
The price for air-to-water is £8,000–£16,000 (0% VAT on homes), before the grant. Eligible homes in England and Wales can get a £7,500 Boiler Upgrade Scheme grant towards it and the installer applies.
Pricing air source heat pumps in Great Kingshill
Before we fix a price, we need to know a few things. We look at:
- The distance and route between the indoor and outdoor units
- The size of the job
- A single visit or a regular plan
The cost depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before any work starts, so you know where you stand.
Before you get in touch
When you call or email, these details help:
- The make and model of the system, from the label
- A few pictures of the room and the wall the unit is on, or will go on
- The address and the type of property
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Heat pumps in Great Kingshill: local notes
About 48% of homes in the Great Kingshill area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 85% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near Church of the Good Shepherd, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. With Hughenden Manor about 2.1 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump.

Your questions about air source heat pumps in Great Kingshill
Can I fit a heat pump in Great Kingshill without planning permission?
It depends on the property. The half-mile around the middle of Great Kingshill holds about 5 listed buildings and structures. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Great Kingshill, typically Buckinghamshire council).
Is Great Kingshill within the area you cover?
Yes. Great Kingshill is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
How much does an air source heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
