About our commercial air conditioning in Forest Hill
Server rooms and comms rooms need cooling that keeps going. We look at the heat load and how the room is used, and can discuss backup units, so a single fault does not leave the room without cooling. Common call-outs are for offices that get too hot in summer and IT rooms that need resilient cooling, on ceiling cassettes, wall-mounted split systems and multi-split systems.
In Forest Hill, as anywhere in England, larger systems need F-gas leak checks, and over 12 kW of cooling a TM44 inspection is required. We keep the F-gas records and flag what’s coming up.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Different systems, different jobs
Shops and restaurants
Where appearance matters, ducted or cassette units keep equipment out of sight.
F-gas records and TM44
An accredited energy assessor carries out the TM44 inspection. We do not inspect, but we get systems ready and do the follow-up work.
Commercial air conditioning around Forest Hill
There are about 210 restaurants, cafés and canteens, about 63 schools and colleges and about 70 care homes, nurseries and hospitals within about 1.5 miles of central Forest Hill, according to the Food Standards Agency’s register. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. About 57% of homes in and around Forest Hill were built before 1919, according to VOA council tax data, and about 58% of households live in flats, according to the 2021 Census. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. London commercial jobs usually involve a landlord or managing agent, and plant space is often tight.
Churches and halls such as Honor Oak Christian Fellowship Centre 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. Clinics, dental practices and pharmacies around Dulwich Community Hospital (about 1.5 miles north-west) normally want quiet indoor units with filters that are simple to keep clean.
Forest Hill is about 2 miles south-east of East Dulwich, in Greater London.

Other services in Forest Hill
Landlords, agents and facilities managers
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
Records are where property maintenance often slips. Each visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Pricing commercial air conditioning in Forest Hill
The survey or diagnosis tells us what the work involves. The main factors are:
- Whether it’s a simple split or a larger system
- The number of rooms, units or zones
- Whether we need access equipment for high-level work
What you pay reflects the actual work. That is why every job is looked at first, and the price is agreed before work begins.
Asking for a quote
You do not need the technical terms. Just send:
- A photo of the consumer unit with the cover closed
- The make and model of the system, from the label
- Any previous service or F-Gas records
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To start, ring us on 07833 053749.
What we do, step by step
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes from a couple of days for a few cassettes to a planned programme for a whole building. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Forest Hill.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- 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
- Arrange for someone to be there to let us in
Get a fixed-price quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.
Advice
Questions from Forest Hill
Can I fit air conditioning in Forest Hill without planning permission?
The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Forest Hill Conservation Area, close to central Forest Hill. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to Southwark council, which is usually the planning authority for Forest Hill when it matters.
Can you do commercial air conditioning in Forest Hill?
We do: Forest Hill falls inside our working area. To start, call us on 07833 053749 or fill in the contact form with a few photos.
When is a TM44 inspection required?
Over 12 kW, a TM44 inspection is needed at least every 5 years. The rules are set out on GOV.UK and we will help with the system side.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What accreditations do you have?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Can you come out in an emergency?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
