Air source heat pumps in Castle Hill, done properly
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. Common call-outs are for wanting to stop using oil, LPG or gas for heating and deciding which kind of heat pump suits the home, across radiator systems, air-to-water heat pumps and homes heated by oil, LPG or gas.
Older and listed homes in villages like Castle Hill need extra care, and permitted development does not cover listed buildings, so consent comes first.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Leave it or put it right?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. Booking before summer means the work in Castle Hill is done before the hot weather.

Homes in Castle Hill and heat pumps
The Valuation Office Agency’s council tax figures put about 47% of homes in Castle Hill and the neighbourhoods around it before 1919, and about 78% of households live in detached or semi-detached houses, according to Census 2021 figures. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Live in one of the older houses around Parish Church of All Saints? Expect the survey to look closely at heat loss and at the building’s planning status. With Scotney Castle about 4.3 miles south, it’s worth asking whether your own home is listed before planning a heat pump.

How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes.

Advice
Questions from Castle Hill
Is the heat pump grant available in Castle Hill?
Castle Hill is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. You do not apply yourself: the MCS certified installer does, which is us.
Is a heat pump in Castle Hill permitted development?
That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of Castle Hill. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Tunbridge Wells council, typically the authority for Castle Hill.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Do you cover Castle Hill?
Yes. We cover Castle Hill and the rest of Kent, as part of our area across London and the South East. For a fixed-price quote, ring 07833 053749 or send an email.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Are you F-Gas certified?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Let and managed properties
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
Aftercare tips
A little care keeps the system in better shape. Our advice:
- Know the servicing conditions in your warranty
- Leave space around the outdoor unit
- Seal draughts where you can
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.
Do not cover radiators with furniture or heavy curtains so the heat can get into the room.
