Air conditioning installation in Cotman's Ash
Across Cotman's Ash, every installation follows the same steps: a site survey, or pictures for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. The price is fixed up front and the records are handed over at the end. People searching for “air con near me” in Cotman's Ash want two things: a sensible price and someone qualified. Our typical prices are on the site, and every install is done by F-Gas qualified engineers.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes.
Villages like Cotman's Ash often have older houses and cottages, some of them listed. We check that first, because permitted development does not apply within the grounds of a listed building.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Common problems we fix in Cotman's Ash
Rooms overheat mostly because of heat they gain during the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and the heat lingers long after the sun has moved round.
The things we’re asked about most include:
- Bedrooms and offices that overheat in summer
- Rooms heated by plug-in heaters
- A study or office that overheats during the day
About 3.4 miles north-west stands Lullingstone Castle. Listed homes in any area need consent first, so tell us if yours is one.
What to look for in a quote
- Why the equipment they’re quoting suits the job
- Whether the manufacturer’s warranty depends on regular servicing
- Whether testing, commissioning and paperwork are included
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
If in doubt, ring us on 07833 053749 and we will say what we think before booking.

What the work involves, system by system
Multi-split systems
Indoor units on a multi-split do not all have to look the same, choosing what suits each room, depending on the model. We plan the mix on the survey.
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill and kept as tidy as the building allows.

Air conditioning around Cotman's Ash
About 43% of homes in Cotman's Ash and the neighbourhoods around it date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 82% of households in detached or semi-detached houses. We check the wall construction on homes of that age, as it decides how the pipework goes through. Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split.
If your home is in one of the older streets near Church of Saint Mary the Virgin, it’s worth checking whether it’s listed or in a conservation area before an install.

FAQs for Cotman's Ash
Do you cover smaller places like Cotman's Ash?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I fit air conditioning in Cotman's Ash without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The centre of Cotman's Ash is in a conservation area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Sevenoaks council, usually the authority for Cotman's Ash.
Can the outdoor unit go on a roof or at ground level?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. Noise near bedrooms and boundaries is part of the decision, and the position can affect planning.
Is air conditioning possible in a flat?
Often, yes, but there are extra steps. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls, so check the lease. Planning rules for flats are tighter too, so we point out anything that may need permission on the survey. This is general information, not legal advice.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Does air conditioning work as heating?
In most cases, yes: modern splits are normally heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
How the visit works
If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. For businesses, we can typically work room by room or zone by zone. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. A note on how to find the property and where to park makes a visit to Cotman's Ash easier.

- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
