Commercial air conditioning in Chatham Green, done properly
Most businesses need to keep trading while the work is done. Work can be done in the evening, at weekends or in phases, so the building keeps running. The programme is agreed before we start. If the problem is ageing air conditioning that keeps breaking down and workspaces that overheat on warm days, we can help.
If you run a village hall or similar building near Chatham Green, heating and cooling that warms up fast suits a space used on and off.
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.

A note on how to find the property and where to park makes a visit to Chatham Green easier.

Common questions in Chatham Green
Can I fit air conditioning in Chatham Green without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Chatham Green holds about 7 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 isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask Chelmsford council, which is typically the planning authority for Chatham Green.
Can you do commercial air conditioning in Chatham Green?
Yes. We work across London and the South East from our base in East Grinstead, and Chatham Green is part of that. To start, call us on 07833 053749 or email us with a few pictures.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Can you work around our opening hours?
Yes. Work can be scheduled around your hours and phase it where necessary.
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 is a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Will skipping a service affect the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we’ll explain them, and book the service at the interval they recommend.
Do you offer commercial maintenance contracts?
We do, with contracts covering servicing, leak checks and the paperwork. We agree the schedule and cost up front.
Why deal with it now?
TM44 inspections are required at least every 5 years for systems over 12 kW. The recommendations often point to simple improvements and we can do the work they recommend. Planning ahead for a job in Chatham Green means we can bring everything needed.
Our prices page shows typical ranges, but each job is priced on what it involves. Call for a fixed-price quote, and we will talk you through it.

For landlords and property managers
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side and send the records to whoever needs them.
Facilities teams in offices, schools and public buildings book us too across Essex. Work can be phased by floor, zone or building around the people who use them.
What we’re called out for in Chatham Green
A TM44 report, an F-gas audit or an insurer’s question can prompt the call. We carry out the work and make sure the paperwork is in order, so you can show what’s been done.
Common reasons people call us are:
- Systems that need out-of-hours or phased installation
- Commercial systems near the end of their life
