How we handle commercial air conditioning in St James's
Commercial air conditioning is a big part of what we do, for businesses in St James's and the rest of 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. If the problem is comms rooms without enough cooling and workspaces that overheat on warm days, we can sort it out.
Commercial systems in St James's are often in shared buildings: offices above shops, restaurants below flats. So landlord consent, plant positions and noise all need agreeing first, and installs are often done out of hours.
Any work on the refrigerant circuit is recorded: 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.

Owner checks or an engineer?
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
How the visit works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Let us know who controls access to the building in St James's, as that saves time on the day.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- 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.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- We commission the system, record the refrigerant details and hand over the controls and documents.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Plan for pets to be kept clear during the visit
- Mention any parking restrictions near the property

Cooling for St James's businesses
There are about 4,152 cafés, restaurants and staff canteens, about 246 hotels and guest houses and about 94 schools and colleges within about 1.5 miles of central St James's, according to the Food Standards Agency’s register. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. About 54% of homes in St James's and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 94% of households live in flats, according to the 2021 Census. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
For a school like Soho Parish CofE Primary School, air conditioning work is best done out of term. If your office near London Charing Cross station has a comms or server room, it needs cooling all year, not just in summer.

Pricing commercial air conditioning in St James's
A fixed price needs a few facts first. We look at:
- Whether it’s a simple split or a larger system
- Whether we need access equipment for high-level work
- Whether it’s a one-off job or part of a maintenance contract
The cost depends on the type of system and how many units are involved, how easy the units are to reach and the parts and time the job needs. You get a fixed price before work begins, so you know where you stand.
Before you get in touch
To help us quote quickly, please include:
- Wide photos of the room or the existing unit
- Where the outdoor unit is, or where you’d like it
- The make and model of the system, from the label
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, phone 07833 053749 or fill in the contact form.
Your questions about commercial air conditioning in St James's
Do I need planning permission for air conditioning in St James's?
There’s no single answer: the building and the outdoor unit position decide it. The Regent Street Conservation Area takes in the middle of St James's. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the local planning authority (for St James's, usually Westminster council).
Is St James's in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and St James's is part of that. Tell us a little about the job and we’ll take it from there.
Can you work around our opening hours?
Yes, we plan out-of-hours, weekend and phased installs so the business keeps running. The programme is agreed with your quote.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Why deal with it now?
One failing outdoor unit can affect many rooms. Regular servicing finds problems early and keeps the building comfortable. Getting the work done in St James's before summer avoids the busiest weeks.
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account and give you a fixed price before we start.
