About our commercial air conditioning in St Margarets
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 explain the options and why we’d choose one over another. If you are dealing with systems over 12 kW due a TM44 inspection and older systems on refrigerants that are getting scarcer, we can help.
London buildings in St Margarets can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems can serve many indoor units from a small number of outdoor units.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Let and managed properties
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so each one has its own history.
Whether it’s one property or many, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
What the work involves, system by system
Ducted systems
One ducted unit can serve more than one area, depending on the layout.
F-gas records and TM44
TM44 inspections are done by accredited energy assessors. We are not assessors, but we prepare the system and carry out the improvements the report recommends.
Business air conditioning in St Margarets
The FSA’s food hygiene register shows about 293 cafés, restaurants and staff canteens, about 10 hotels and guest houses and about 21 schools and colleges within roughly a mile and a half of the centre of St Margarets. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads.

The process
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and explain it all to you. On site, the work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Parking bays, permits and roof or balcony access are the first things we ask about in St Margarets.
- First comes a survey, looking at the building and how it’s occupied.
- You get our recommendation and a fixed price.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
How to prepare
- Mention any parking restrictions near the property
- Let us know if the units are on a roof, a high wall or in a locked area
- Name a contact who can meet us at the agreed time

Common questions in St Margarets
Do I need permission to put air conditioning in my flat in St Margarets?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Is planning permission needed for air conditioning in St Margarets?
It comes down to the building and the spot chosen for the outdoor unit. Central St Margarets sits inside the St Margaret's Estate Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not 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 local planning authority (for St Margarets, typically Richmond-Upon-Thames council).
Which manufacturers do you install and repair?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How often is a TM44 inspection needed?
Over 12 kW, a TM44 inspection is needed at least every 5 years. GOV.UK has guidance on how it works and we will help with the system side.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Can I do any of the installation myself?
Not the refrigerant work. 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 work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
