Air conditioning in Long Ditton
Across Long Ditton, every installation follows the same steps: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. A lot of the calls we get from Long Ditton are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
In a London area like Long Ditton, many of the homes we are asked about are flats, maisonettes and terraced houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, so we write up the proposed positions for them to see.
We’re an F-Gas certified company, 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.

Your questions about air conditioning in Long Ditton
Can I have air conditioning in a flat in Long Ditton?
Normally, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is planning permission needed for air conditioning in Long Ditton?
It comes down to the building and the spot chosen for the outdoor unit. Central Long Ditton is a short walk from the Long Ditton 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 local planning authority (for Long Ditton, usually Kingston-Upon-Thames council).
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Do you work on all makes?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Can air conditioning heat my home as well?
Typically, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Keeping the system healthy
After the visit, a few habits help:
- Use moderate settings for comfort and economy
- Do not cover or box in the outdoor unit
- File the paperwork with the manual
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Have the system serviced once a year. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early and keeps the warranty paperwork right where servicing is a condition.
Different systems, different jobs
Ducted systems
Ducted air conditioning hides the indoor unit in a ceiling void or loft, and all you see is a discreet grille. It’s popular where people don’t want a unit on the wall.
Wall-mounted split systems
A single-room split is typically £1,200–£2,200 + VAT, including supply, installation, commissioning and F-Gas documentation. Where you sit in that range depends on the pipe run, access and electrics.
Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Central heating repairs
- A building fabric problem such as single glazing or no loft insulation
- Stuffy rooms that need fresh air rather than cooling
Not sure which it is? You can give us a ring on 07833 053749 or drop us a line and we will tell you honestly before you book.

Homes in Long Ditton and air conditioning
The Valuation Office Agency’s council tax figures put about 35% of homes across Long Ditton and its surrounding area before 1919, and about 53% of households live in flats, according to the last census (2021). Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder normally decide where an outdoor unit can go, and the permitted development rules for flats are tighter. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes anything from a day for one room to several days for a multi-room or ducted system. For a job in Long Ditton, tell us about parking, permits and access to the building when you get in touch.
- 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.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Before we arrive
- Keep pets out of the rooms we’re working in
- Dig out any previous service or F-Gas records
- Mention any parking restrictions near the property
