How we handle air conditioning in Great Leighs
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. Air conditioning installation in Great Leighs starts with a site survey, followed by a fixed-price quote with the brand, model and every part of the job set out.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes.
Around Great Leighs, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

What the work involves, system by system
Wall-mounted split systems
A wall-mounted split is the most common choice for a single room. One unit inside, one outside, connected by pipework, a cable and a drain, routed as agreed on the survey.
Multi-split systems
With a multi-split, one outdoor unit serves two or more rooms. It’s a neat answer when space outside is limited and several rooms need it and each indoor unit has its own controls.
The process
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. 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. For a place like Great Leighs, the timing is set with you and the travel is our side of the planning.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any managing agent or landlord rules we need to follow
- Move furniture away from the wall where we’ll be working

Air conditioning in Great Leighs: local notes
About 73% of households live in detached or semi-detached houses, according to Census 2021 figures. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed. Around Church of St John the Evangelist, a quick check of the listing and conservation maps is part of planning any install.

Your questions about air conditioning in Great Leighs
Is Great Leighs within the area you cover?
Yes. Great Leighs is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Do I need planning permission for air conditioning in Great Leighs?
It depends on the property. Historic England lists about 19 buildings and structures within half a mile of the centre of Great Leighs. 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 is not allowed under those rules. If there’s any doubt, we ask the planning department at Chelmsford council, usually the authority for Great Leighs.
Do you provide F-Gas records?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Where will you put the outdoor unit?
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.
Can you fit air conditioning in a leasehold flat?
That depends on the lease, the building and where the outdoor unit could go. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent, and we check the options on the survey. This is general information, not legal advice.
Do you offer emergency call-outs?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Call 07833 053749 and tell us what’s happened.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Fixed-price quotes for air conditioning in Great Leighs
The survey or diagnosis tells us what the work involves. The main factors are:
- How far the pipework has to run, and where
- What kind of system it is
- The condition of any existing system
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, call 07833 053749 or use the quote form for straight advice and a fixed price.
What to send for a quote
Good pictures often save a visit. The most useful are:
- Any previous service or F-Gas records
- A few pictures of the room and the wall the unit is on, or will go on
- A photo of the consumer unit with the cover closed
Getting a quote is straightforward. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
