Air source heat pumps in Dunk's Green, done properly
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. Common call-outs are for comparing heat pump types and wanting to stop using oil, LPG or gas for heating, on air-to-water heat pumps, hot water cylinders and air-to-air heat pumps.
Older and listed homes in villages like Dunk's Green need extra care, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Signs you need air source heat pumps in Dunk's Green
Many enquiries start with a question about the Boiler Upgrade Scheme. Eligibility depends on the property, the system and the scheme rules, so we check before you commit.
Any of these is worth a proper look:
- Replacing a combi boiler with a heat pump
- Deciding on the outdoor unit position
- Checking emitters for a heat pump
Older homes near Plaxtol Church may need extra checks for planning and heat loss before a heat pump is designed.
What to look for in a quote
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether the manufacturer’s warranty depends on regular servicing
- Whether they looked at the job before pricing it
What owners can safely do
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and phone us on 07833 053749 or send an email.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Dunk's Green: your questions answered
Will you come out to Dunk's Green?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Does the Boiler Upgrade Scheme cover homes in Dunk's Green?
Yes, if the home and the heat pump meet the scheme’s rules: Dunk's Green is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.
Should I choose air-to-water or air-to-air?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling, and we help you choose. Both are part of what we install.
What does an air-to-water heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales though not every home qualifies.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Dunk's Green and across Kent. Tell us who should receive the paperwork.
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.

What happens on the day

- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Mention any managing agent or landlord rules we need to follow
- Make sure someone can let us in at the agreed time
- Make sure we can reach the outdoor unit, or where it will go

Homes in Dunk's Green and heat pumps
About 73% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses normally have space for an outdoor unit and a hot water cylinder. In the mile around Dunk's Green’s centre, 5 conservation areas have been designated. Historic England lists about 16 buildings and structures within half a mile of the centre of Dunk's Green, including Spoute House (grade II*). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with Tonbridge and Malling council, normally the planning authority here where necessary.
With Old Soar Manor about 0.9 miles north-east, it’s worth asking whether your own home is listed before planning a heat pump.

Looking after your system
A little care keeps the system in better shape. Our advice:
- Leave space around the outdoor unit
- Book a yearly service
- Leave indoor units unobstructed
If anything does not seem right after installation, phone 07833 053749 or fill in the contact form and we will look into it. Annual servicing helps keep the system working well.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
