Commercial air conditioning in Westerham
Every commercial job is commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, and a fixed-price quote follows. So you know exactly what you are getting and what it costs. The work covers wall-mounted split systems, VRF systems and ceiling cassettes, and people most often call us about server rooms running too warm and leak check schedules that have slipped.
For a business in Westerham, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the F-gas records and flag what’s coming up.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Common questions in Westerham
Is Westerham in your area for commercial air conditioning?
Yes, Westerham is within the area we cover. To start, phone us on 07833 053749 or fill in the contact form with a few pictures.
Do I need permission to put air conditioning in my flat in Westerham?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What does the operator have to do under the F-gas rules?
Operators of systems from 5 tCO2e upwards need leak checks and records. The intervals are at least yearly from 5 to under 50 tCO2e, and 6-monthly from 50 to under 500 tCO2e and we carry out the checks and keep the records.
Which commercial systems do you fit?
Wall-mounted, multi-split, ducted, cassette and VRF systems from leading brands. We explain the options after a site survey.
Do you look at the job first?
Yes. Every job is looked at first, on a survey, or from your pictures and details where the job is simple. A fixed-price quote follows.
How long does a commercial installation take?
As a guide, it takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Out-of-hours and phased work can spread the programme but keeps the business running.
Let and managed properties
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Honest limits
Commercial air conditioning can’t fix everything, and we will tell you before any work starts. It won’t put right:
- Fire safety design or fire risk assessments
- Boiler installation or repair
- Planning permission or landlord consent on your behalf
If you’re not sure, just phone us on 07833 053749 and we’ll give you a straight answer.

Commercial air conditioning in Westerham: local notes
The FSA’s food hygiene register shows about 19 cafés, restaurants and staff canteens in and around Westerham, up to about a mile and a half out. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
For a surgery or clinic in the Tandridge Priory area, a planned maintenance contract keeps the system clean and its records up to date.

What we are called out for in Westerham
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine and windows alone cannot always shift it. A system sized for the real heat load deals with it.
Common reasons people call us include:
- Ageing air conditioning that keeps breaking down
- Offices that get too hot in summer
- New tenancies needing cooling and heating
Churches and halls such as Church of St Mary the Virgin are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.
What your quote should include
- Whether a new circuit is included and who certifies it
- Exactly what the price includes, from supply and fitting to commissioning
- What paperwork you’ll receive afterwards
How it works
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes a few days for a small shop or office, longer for VRF across several floors. Photos of the room and where the outdoor unit could go let us plan most of a visit to Westerham in advance.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- Installation is scheduled to fit the business, with out-of-hours and phased work where needed.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Before we arrive
- Keep pets out of the rooms we’re working in
- Move furniture away from the wall where we’ll be working
- Give us access to the outside wall, roof or yard where the outdoor unit sits
