Air conditioning for homes and businesses in Heyshott Green
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be and we talk you through it on the survey. When someone in Heyshott 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.
In a village like Heyshott Green, many homes are older, and some are listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

FAQs for Heyshott Green
Do I need planning permission for air conditioning in Heyshott Green?
The answer turns on the property and where the outdoor unit would sit. Central Heyshott Green is a short walk from the Heyshott Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Heyshott Green, typically Chichester council).
Will you come out to Heyshott Green?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
How long does air conditioning installation take?
It takes anything from a day for one room to several days for a multi-room or ducted system. We confirm the time when we quote, so you can plan around it.
Should I choose wall-mounted, ducted or cassette?
There’s no single best type. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. The survey ends with a recommendation and the reasons.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your pictures and details where the job is simple. Then you get a fixed-price quote.
What does it cost to install air conditioning?
Typically £1,200–£2,200 + VAT for a single-room split, depending on the room, the access and the pipe route. Where you sit in the range depends on pipe length, access, electrics and the model, and commercial systems are priced after a survey.
How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes anything from a day for one room to several days for a multi-room or ducted system. We agree a date with you and plan the visit to Heyshott Green so we arrive with what’s needed.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Have the make and model of any existing unit to hand
- Tell us about any building rules, permits or sign-in

Related advice
What the work involves, system by system
Ceiling cassettes
Cassettes are good at even airflow across a large floor area, and the slim grille sits neatly in the ceiling.
Ducted systems
With a ducted system, the indoor unit sits out of sight above the ceiling, and all you see is a discreet grille. It suits rooms where a visible unit wouldn’t work.
Landlords, agents and facilities managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
