Air conditioning installation in Trench Green
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, along with the manufacturer’s warranty terms on your quote. When someone in Trench Green asks us for air con, the first questions are normally price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes.
Villages like Trench Green 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, and the outdoor unit position is chosen to suit the building.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Air conditioning around Trench Green
The 2021 Census found about 91% of households in detached or semi-detached houses. Houses usually have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
With historic houses such as Mapledurham House about 1.1 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Properties in Trench Green get the same service as everywhere we cover: diagnosis first, a fixed price and proper paperwork when we’ve finished.

Questions from Trench Green
Is Trench Green in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Trench Green is part of that. Tell us a little about the job and we’ll take it from there.
Do I need planning permission for air conditioning in Trench Green?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Trench Green holds about 6 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask South Oxfordshire council, which is normally the planning authority for Trench Green.
Do I need a new electrical circuit?
Normally, yes. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.
Where does the outdoor unit go?
We agree it with you on the survey. It must have clear airflow and space for servicing, and a position facing a road can bring extra planning considerations. We explain the options and any permissions to check.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
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. Where you sit in the range depends on pipe length, access, electrics and the model, and commercial systems are priced after a survey.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Do you need air conditioning in Trench Green?
Everything that uses electricity in a room ends up as heat. A small office or a busy room can warm up fast with equipment and people in it, even when it is not especially hot outside.
These are the situations we see most often:
- Expensive direct electric heating
- A home office that warms up with screens and equipment
- Rooms under the roof that stay hot into the night
If your home is in one of the older streets near Church of St Margaret and Bardolf Aisle, it’s worth checking whether it’s listed or in a conservation area before an install.

What we do, step by step
If the system has to be off for part of the visit, we tell you before work begins so it doesn’t catch you out. For businesses, we can normally 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. We agree a date with you and plan the visit to Trench Green so we arrive with what’s needed.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Name a contact who can meet us at the agreed time
- Dig out any previous service or F-Gas records
Getting a price
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

Honest limits
In fairness, some problems need a different answer:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- An installation that needs consent nobody has given yet
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
Not sure which it is? You can give us a ring on 07833 053749 or fill in the contact form and we will tell you honestly before you book.
