Air con installers in Marsh Green
Most air conditioning needs its own electrical supply from the consumer unit. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. Most split systems we fit in Marsh Green are reversible: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.
A typical install in Marsh Green is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
For a home in or near Marsh Green, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating does not reach well, such as a garden room or loft.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

The process
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. For businesses, we can usually work room by room or zone by zone. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. For a village like Marsh Green, tell us about narrow lanes, gates and parking when you book.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Clear access to the fuse board
- Dig out any previous service or F-Gas records

Common questions in Marsh Green
Is Marsh Green in your area for air conditioning?
Yes. Marsh Green is one of the places we cover. Just ring 07833 053749 or use the quote form with a few details.
Is planning permission needed for air conditioning in Marsh Green?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Marsh Green is in a conservation area. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with Sevenoaks council, which is typically the planning authority for Marsh Green.
How much does air conditioning installation cost?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Long pipe runs, difficult access, a new circuit and premium indoor units push the price up, while commercial systems are priced after a survey.
Where does the outdoor unit go?
It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
Is air conditioning possible in a flat?
Often, yes, but there are extra steps. You’ll usually need the landlord’s or management company’s consent for the outdoor unit and the pipe route, so check the lease. Permitted development rules for flats are also tighter than for houses, so we point out anything that may need permission on the survey. This is general information, not legal advice.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
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 refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.

Rented and managed buildings
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side and send the records to whoever needs them.
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so each one has its own history.
Fixed-price quotes for air conditioning in Marsh Green
You will get a fixed price before work begins. It’s based on:
- One-off work versus a regular service cycle
- Whether it’s a simple split or a larger system
- Whether the existing supply is suitable
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we will go through it with you.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The paperwork from the last service, if you have it
- The outside wall, roof or yard where the outdoor unit sits or would go
- Your consumer unit or fuse board
Here’s what helps us quote: where the property is and what kind of building it is, photos of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, ring 07833 053749.
