About our commercial air conditioning in Gun Hill
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out. We don’t carry out the inspection itself, but we prepare the system and do the work it recommends. Common call-outs are for buildings that can’t close for the work and planning ahead for the HFC phase-down, on multi-split systems, wall-mounted split systems and ceiling cassettes.
In a village like Gun Hill, commercial air conditioning is usually for a pub, a shop, a surgery, a village hall or a rural business. Older buildings may be listed, so planning comes first.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Before you call an engineer
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
What commercial air conditioning cannot fix
To be straight with you, there are a few things this work won’t fix:
- Plumbing beyond the condensate drainage
- Planning permission or landlord consent on your behalf
- Major builder’s work such as new openings in structural walls
Not sure which it is? You can call 07833 053749 or use the quote form and we will tell you honestly before booking.
What the work covers
- Wall-mounted split systems
- VRF systems
- Ceiling cassettes
- Server and comms room cooling
- Ducted systems
- Multi-split systems
What affects the cost of commercial air conditioning
Your quote is based on your property. We take into account:
- The type of system, from a single split to a larger system
- Access, including height, roofs and ladders
- How many units are involved
What you pay reflects the actual work. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before work begins.
Helping us quote
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A few photos of the room and the wall the unit is on, or will go on
- The address and the type of property
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To start, give us a ring on 07833 053749 or send an email.
What happens on the day
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, it takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Rural lanes and tight entrances are worth mentioning before a visit to Gun Hill.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- Installation is scheduled to fit the business, with out-of-hours and phased work where necessary.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
Getting ready for the visit
- Let us know where the consumer unit is
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Dig out any previous service or F-Gas records

FAQs for Gun Hill
Can you do commercial air conditioning in Gun Hill?
Yes, Gun Hill is within the area we cover. Tell us a little about the job and we’ll take it from there.
Is planning permission needed for air conditioning in Gun Hill?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Gun Hill holds about 9 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Gun Hill, usually Wealden council).
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book, and we are happy to show ours.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
