Long Ditton: your questions answered
Do I need planning permission for air conditioning in Long Ditton?
It depends on the property. The Long Ditton Conservation Area is close to the centre of Long Ditton. 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 I need permission to put air conditioning in my flat in Long Ditton?
Often, yes, but the lease and the freeholder typically have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Why does F-Gas certification matter?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Who is responsible for 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.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Can you work around our opening hours?
Yes. Work can be scheduled around your hours, including phased work floor by floor.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in Long Ditton and across Greater London. Tell us who should receive the paperwork.
How we handle commercial air conditioning in Long Ditton
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we’re not assessors, but we prepare systems for inspection and act on what the report finds. Typical jobs include missing F-gas records for commercial systems and systems over 12 kW due a TM44 inspection, on server and comms room cooling, multi-split systems and ceiling cassettes.
Commercial systems in Long Ditton are often in shared buildings: offices above shops, restaurants below flats. So landlord consent, plant positions and noise all need agreeing first, and the work is normally planned around trading hours.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Why act early in Long Ditton
F-gas leak checks and records are legal duties for most systems at or above 5 tCO2e. Falling behind leaves the operator without the evidence the rules expect, and it’s simpler to keep on schedule with a contract. Planning ahead in Long Ditton means you choose the date, not the weather.
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account, and the price is fixed before work begins.

How the job changes from property to property
VRF and VRV systems
VRF systems hold more refrigerant than small splits so leak checks and records often apply. We work out the tCO2e and set the check schedule.
Ceiling cassettes
Cassettes leave only the grille on show, which keeps the look of the ceiling tidy.

What commercial work looks like in Long Ditton
Food Standards Agency data counts about 126 cafés, restaurants and staff canteens, about 5 hotels and guest houses and about 29 schools and colleges in and around Long Ditton, up to about a mile and a half out. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. The Valuation Office Agency’s council tax figures put about 35% of homes in Long Ditton and the neighbourhoods around it before 1919, and about 53% of households live in flats, according to the 2021 Census. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. London commercial jobs normally involve a landlord or managing agent, and plant space is often tight.
A bursar or site manager at a school like Long Ditton Infant and Nursery School will want the install planned around the school calendar, and we work to that.

The process
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes a few days for a small shop or office, longer for VRF across several floors. Before a visit in Long Ditton, we ask where the van can stop and how we reach the outdoor unit.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- The system goes in, from units and pipework to drainage, wiring and controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Getting ready for the visit
- Mention any roof access, ladders or high-level work
- Mention any managing agent or landlord rules we need to follow
- Unlock any gate, garage or side passage we need
