How we handle commercial air conditioning in Forest Green
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor. We don’t carry out the inspection itself, but we prepare the system and do the work it recommends. The work covers ceiling cassettes, server and comms room cooling and ducted systems, and common reasons people get in touch are fit-outs and refurbishments that need new air conditioning and offices that get too hot in summer.
For a business near Forest Green, outdoor units usually have room at the back of the building.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Looking after your system
Simple habits make a real difference. We recommend:
- Plan the air conditioning alongside the fit-out
- Note the 5-yearly TM44 date for systems over 12 kW
- Book a maintenance contract to keep servicing on schedule
We show your team how to use the controls, so the system is run the way it was designed. Simple settings make a real difference to comfort and running.
Keep records of every service, leak check and repair. For systems at or over 5 tCO2e, they’re required.
Your questions about commercial air conditioning in Forest Green
Is air conditioning in Forest Green permitted development?
It depends on the property. The Forest Green Conservation Area takes in the middle of Forest Green. 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 the planning department at Mole Valley council, typically the authority for Forest Green.
Do you cover smaller places like Forest Green?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
Can you do our TM44 air conditioning inspection?
We’re not accredited energy assessors, so we don’t inspect. We can prepare for the inspection and put right what it finds.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
Does my building need a TM44 inspection?
Systems with an effective rated output over 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out and we can help before and after.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.

Cooling for Forest Green businesses
At about 27 miles from central London, Forest Green sits inside the area we cover across London and the South East.
Larger commercial systems need F-gas leak checks and, over 12 kW of cooling, TM44 inspections. Before any plant goes outside a building like Holy Trinity, its trustees may need planning or heritage advice, and we work with whoever gives it.

How the job changes from property to property
Offices
Installation can be done out of hours or floor by floor, so the office stays open.
Ceiling cassettes
Cassettes leave only the grille on show, which keeps the look of the ceiling tidy.
How it works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work 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 Forest Green.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the 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.
Preparing for the visit
- Clear a path to the units and the space around them
- Let us know if the units are on a roof, a high wall or in a locked area
- Keep pets out of the rooms we are working in
