Commercial air conditioning for homes and businesses in Brentford
We design, install and look after air conditioning for businesses in Brentford and across Greater London. That includes offices, shops, restaurants, hotels, schools and server rooms, and each one gets a system chosen for how the space is used. The work covers ceiling cassettes, wall-mounted split systems and multi-split systems, and the jobs we see most are workspaces that overheat on warm days and work raised by a TM44 inspection.
Commercial systems in Brentford are often in shared buildings: offices above shops, restaurants below flats. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and the work is normally planned around trading hours.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

When to call us in Brentford
Schools and public buildings often need work done in the holidays. Installation can be programmed for the holidays so lessons aren’t disrupted.
Keep an eye out for these signs:
- Older systems on refrigerants that are getting scarcer
- Buildings that cannot close for the work
- Workspaces that overheat on warm days
Schools such as St Paul's CofE Primary School normally have the work done in the holidays, when classrooms are empty.
Questions to ask before you book
- What’s in the price and what isn’t
- If the figure could change on the day
- What happens if the job turns out to be different on the day
Looking after it afterwards
Every system needs looking after, and most of it is easy. Our tips:
- Keep a log for each system
- Involve us at the planning stage of a refurbishment
- Report noises, leaks and faults early
After commissioning, you get the F-gas records, handover notes and the manufacturer’s paperwork. Keep them together for future servicing and inspections.
Simple control settings help. Systems fighting each other, or set to extremes, waste effort, and we can help set them up.
Your questions about commercial air conditioning in Brentford
Can you do commercial air conditioning in Brentford?
Yes, Brentford is within the area we cover. Tell us a little about the job and we will take it from there.
Do I need planning permission for air conditioning in Brentford?
The answer turns on the property and where the outdoor unit would sit. Central Brentford is a short walk from the St Paul's Brentford Conservation Area. 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 the local planning authority (for Brentford, typically Hounslow council) when it matters.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
How often is a TM44 inspection needed?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. The rules are set out on GOV.UK, and we can help you prepare.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we are happy to show ours.
The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. The work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Let us know who controls access to the building in Brentford, as that saves time on the day.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Let us know if the units are on a roof, a high wall or in a locked area
- Move furniture away from the wall where we’ll be working
Getting a quote

Advice
For landlords and property managers
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
We also work for facilities teams in offices, schools and public buildings in Brentford and across Greater London. Work can be phased by floor, zone or building around the people who use them.
Commercial air conditioning in Brentford: local notes
The FSA’s food hygiene register shows about 378 restaurants, cafés and canteens, about 12 hotels and guest houses and about 49 schools and colleges within 1.5 miles or so of the middle of Brentford. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. Valuation Office Agency council tax records show about 38% of homes in Brentford and the neighbourhoods around it were built in 2000 or later, and about 66% of households live in flats, according to the last census (2021). Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. London commercial jobs normally involve a landlord or managing agent, and plant space is often tight.
For a church or hall like Congregational Church, any outdoor unit needs the right consents first.
