Common questions in Dormansland
Will air conditioning in Dormansland need planning permission?
That depends on the building and where the outdoor unit goes. Around 11 listed entries sit within 0.5 miles of central Dormansland. 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 Dormansland, normally Tandridge council).
Can you do commercial air conditioning in Dormansland?
Yes. We work across London and the South East from our base in East Grinstead, and Dormansland is part of that. Just call us on 07833 053749, or email if that’s easier with a few details.
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.
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How often is a TM44 inspection needed?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. The rules are set out on GOV.UK and we will help with the system side.
What F-gas duties does a business have?
Responsibility is shared between the operator and the certified technicians who work on the system. The operator needs to arrange leak checks and keep records where the system requires them, and we provide both.
Commercial air conditioning in Dormansland, done properly
Commercial systems are commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, and a fixed-price quote follows. That way the system fits the site and the price is clear before work starts. We’re often asked to deal with commercial systems near the end of their life and staff complaining about the temperature, across ceiling cassettes, ducted systems and wall-mounted split systems.
Around Dormansland, there’s usually space for outdoor plant away from the road.
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.

Why act early in Dormansland
A well-planned programme lets the building stay open while the work goes on. Waiting for a failure removes that choice. Waiting rarely makes an air conditioning problem smaller.
What you pay depends on the type of system and how many units are involved, the access and the parts and time the job needs. We give you a fixed price before any work starts, so there are no surprises.

- You get our recommendation and a fixed price.
- The programme is agreed, including any out-of-hours or phased work.

Getting ready for the visit
