St Mary Cray commercial air conditioning
Our engineers work in St Mary Cray on design, installation, servicing and repair of air conditioning for offices, shops, hospitality and public buildings. Diagnosis first, a fixed price and proper paperwork when we finish.
- Work raised by a TM44 inspection
- Planning ahead for the HFC phase-down
- Changes of use that need a new layout
When to call us in St Mary Cray
A fit-out, refurbishment or change of use often means rethinking the air conditioning. More people, new walls or extra equipment alter what the system has to cope with and the system needs to match the new layout.
Keep an eye out for these signs:
- Workspaces that overheat on warm days
- Older systems on refrigerants that are getting scarcer
- Systems over 12 kW due a TM44 inspection
For a school like Poverest Primary School, air conditioning work is best done out of term.
Questions to ask before booking
- What paperwork you’ll receive afterwards
- If the quote is based on a survey, pictures or a diagnosis
- What happens if the job turns out to be different on the day
Commercial air conditioning for homes and businesses in St Mary Cray
The right system depends on the building. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We set out the choices and the reasons behind our recommendation. The work covers server and comms room cooling, VRF systems and ceiling cassettes, and the jobs we see most are changes of use that need a new layout and staff complaining about the temperature.
Commercial systems in St Mary Cray are often in shared buildings: offices above shops, restaurants below flats. So landlord consent, plant positions and noise all need agreeing first, and installs are often done out of hours.
The records are your 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 and it’s worth keeping safe.

How the visit works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes from a couple of days for a few cassettes to a planned programme for a whole building. A few pictures of the room, the outside wall and the fuse board help us plan a job in St Mary Cray.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Before we arrive
- Keep pets and children away from the work area
- Let us know if the building has a permit or sign-in process
- Clear the space around the indoor unit, or where it will go

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Book a maintenance contract to keep servicing on schedule
- Note the 5-yearly TM44 date for systems over 12 kW
- Plan the air conditioning alongside the fit-out
Handover includes a walk-through of the controls so staff can set it up properly. Simple settings make a real difference to comfort and running.
Plan replacements before old systems fail, particularly where they use R410A.
Managing agents and facilities teams in St Mary Cray
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we’ll come back with a fixed-price quote.
Questions from St Mary Cray
Do I need permission to put air conditioning in my flat in St Mary Cray?
Usually, yes, though leaseholders normally need the freeholder’s agreement. 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.
Is air conditioning in St Mary Cray permitted development?
It depends on the property. The half-mile around the middle of St Mary Cray holds about 15 listed buildings and structures. 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 Bromley council, which is usually the planning authority for St Mary Cray.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
What types of commercial air conditioning do you install?
Splits, multi-splits, cassettes, ducted units and VRF from leading brands. We set out the choices after surveying the site.
Can you work around our opening hours?
We do: evening, weekend and phased installation are all possible to keep disruption down. The programme is agreed with your 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 a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
