Managing agents and facilities teams in Box Hill
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we’ll copy in whoever needs it.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Commercial air conditioning in Box Hill, done properly
The business that operates the system has F-gas responsibilities. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We handle the checks and records and remind you when the next is due. Typical jobs include staff complaining about the temperature and systems over 12 kW due a TM44 inspection, across multi-split systems, ceiling cassettes and VRF systems.
For a business near Box Hill, outdoor units typically have room at the back of the building, out of sight and away from neighbours.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Photos of the existing unit help with repairs and servicing in Box Hill.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Getting ready for the visit
- Let us know where we can park and unload
- Unlock any gate, garage or side passage we need
- Clear the space around the indoor unit, or where it will go
How to get a quote

Your questions about commercial air conditioning in Box Hill
Is Box Hill within the area you cover?
Yes. Box Hill is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I get a fixed-price quote for commercial air conditioning in Box Hill?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
How does the warranty work?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Will I get records for the system?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Will I need planning permission?
It can do. The rules differ for heat pumps and cooling-only air conditioning, and for houses, flats, listed buildings and conservation areas. We point out anything that may need permission at the survey and the council makes the decision. This is general information, not legal advice.
What kind of air conditioning can you install in a business?
Everything from wall-mounted units for single rooms to VRF or VRV systems serving whole buildings. Cassettes and ducted units suit offices, shops and restaurants.
When is a TM44 inspection required?
Where the air conditioning is over 12 kW, an inspection is needed at least every 5 years. An accredited energy assessor carries it out and we can help before and after.
