How we handle air source heat pumps in Colt's Hill
A heat pump takes heat from the outside air and moves it into your home with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers air-to-air heat pumps, air-to-water heat pumps and homes heated by oil, LPG or gas, and common reasons people get in touch are moving away from fossil-fuel heating and an oil, LPG or gas boiler near the end of its life.
Older and listed homes in villages like Colt's Hill need extra care, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Common questions in Colt's Hill
Is planning permission needed for a heat pump in Colt's Hill?
It comes down to the building and the spot chosen for the outdoor unit. Central Colt's Hill sits inside a conservation area. 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 do not 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 Colt's Hill.
Do you cover smaller places like Colt's Hill?
Yes. Colt's Hill is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Am I eligible for a heat pump grant?
Quite possibly. The scheme runs in England and Wales and pays £7,500 towards an eligible air-to-water or ground source heat pump, or £2,500 for an air-to-air system that meets stricter conditions. Until March 2027 there’s an extra £1,500 for air source or ground source heat pumps in homes on oil or LPG with no mains gas. The survey is where we check your home against them.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.

The process
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, check the system and explain it all to you. The visit itself takes from a couple of days to around a week, depending on the system and how much of the heating changes. A note on how to find the property and where to park makes a visit to Colt's Hill easier.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Getting ready for the visit
- Make sure someone can let us in at the agreed time
- Let us know if the building has a permit or sign-in process
- Dig out any previous service or F-Gas records

After we have gone
Simple habits make a real difference. Our advice:
- Store the MCS certificate and warranty documents together
- Clear leaves and debris from 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. Steady running suits a heat pump better than switching on and off so we set the controls up with you.
Heat pumps prefer steady, low-temperature running as explained at handover.
What we’re called out for in Colt's Hill
People also ask about air-to-air heat pumps because they heat and cool. They heat rooms through wall, floor or ceiling units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
Most people get in touch when they notice one of these:
- Checking eligibility for a heat pump grant
- Working out where a cylinder could go
- Comparing heat pump types
Period properties close to Five Oak Green Church can suit a heat pump, though insulation and any heritage protection are checked first.
Questions to ask before you book
- What the manufacturer’s warranty covers and for how long
- Exactly what the price includes, from supply and fitting to commissioning
- Whether the quote is a fixed price
