Air source heat pumps for homes and businesses in Cranbrook
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. We’re often asked to deal with plans to switch to electric heating with a heat pump and replacing a combi boiler with a heat pump, across radiator systems, hot water cylinders and air-to-air heat pumps.
Homes around Cranbrook typically have space for an outdoor unit and a hot water cylinder, so the main questions are heat loss, radiators and the electrics.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

What owners can safely do
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749.
Pricing air source heat pumps in Cranbrook
Jobs vary more than people expect. The main factors:
- One-off work versus a regular service cycle
- The distance and route between the indoor and outdoor units
- Which make and model is being fitted or worked on
Typical ranges are on our prices page, but your price depends on the job in front of us. For a fixed-price quote, phone 07833 053749, or email if that’s easier, and we will talk you through it.
What we need to know
You do not need the technical terms. It helps if you can send:
- A few pictures of the room and the wall the unit is on, or will go on
- Your consumer unit or fuse board
- The rating plate or label on any existing unit
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. After a look at the job, by photos or a survey, the price is fixed. To get going, phone us on 07833 053749 or drop us a line.
Cranbrook: your questions answered
Is Cranbrook within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is planning permission needed for a heat pump in Cranbrook?
It depends on the property. Central Cranbrook 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 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 Cranbrook.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
What VAT do I pay on a heat pump?
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%. Businesses pay the standard rate, and this is general information rather than tax advice.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Will I get records for the system?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
Homes in Cranbrook and heat pumps
About 35% of homes in the Cranbrook area were built before 1919, according to VOA council tax data, and the 2021 Census found about 71% of households in detached or semi-detached houses. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Houses usually have space for an outdoor unit and a hot water cylinder.
Period properties close to Congregational Church can suit a heat pump, though insulation and any heritage protection are checked first. Every heat pump design starts with a room-by-room heat loss calculation.

What we do, step by step
Each visit follows the same order: agree the plan on site, protect the area, carry out the job, test what we’ve done and talk you through it. The visit itself takes from a couple of days to around a week, depending on the system and how much of the heating changes. In a place like Cranbrook, parking is rarely an issue, but tell us about gates and access to the back of the property.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Let us know where we can park and unload
- Mention any managing agent or landlord rules we need to follow
