About our commercial air conditioning in Westminster
Server rooms and comms rooms need cooling that keeps going. The design accounts for the equipment’s heat and can include a second unit as backup so one failure does not take everything down. We’re often asked to deal with work raised by a TM44 inspection and planning ahead for the HFC phase-down, across multi-split systems, server and comms room cooling and ducted systems.
In a London area like Westminster, commercial air conditioning goes into offices, shops, restaurants and server rooms, often in shared buildings. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and the work is usually planned around trading hours.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Commercial air conditioning around Westminster
The FSA’s food hygiene register shows about 3,298 cafés, restaurants and staff canteens, about 187 hotels and guest houses and about 85 schools and colleges in and around Westminster, up to about a mile and a half out. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule. About 47% of homes across Westminster and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 94% of households live in flats. 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.
If you look after a school such as Harris Westminster Sixth Form, classroom, office and IT room cooling is usually installed in the holidays. Offices near London Victoria station often need cooling for meeting rooms and server cupboards as well as the main space.
Westminster is about 1 mile south-east of City of Westminster, in Greater London. Wherever you are in the SW1P postcode area, we cover commercial air conditioning. Our Greater London coverage runs to 764 places, and Westminster is one of them.

Leave it or put it right?
A single system failure in a server room can quickly cause problems. Reviewing the cooling and adding resilience is best done in advance. Approvals for flats in Westminster can take longer than the install itself.
The cost depends on the system and the number of rooms or units, the access and the parts and time the job needs. We give you a fixed price before work begins, so there are no surprises.
Why us?
- An F-Gas certified company, as the law requires
- Warranty terms set out brand by brand
- A fixed price before any work starts
- MCS certified heat pump installers
What happens on the day
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. On site, it takes from a couple of days for a few cassettes to a planned programme for a whole building. A note on parking and access helps us plan a visit to Westminster.
- 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.
- The system is commissioned and maintenance can be arranged.
How to prepare
- 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 will be working
- Give us access to the outside wall, roof or yard where the outdoor unit sits
Ask for a quote
Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, give us a ring on 07833 053749, or email if that’s easier.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what commercial air conditioning won’t do:
- Fire risk assessments
- Structural alterations to the building
- Acting as the energy assessor
If in doubt, phone 07833 053749, or email if that’s easier and we’ll say what we think.
What we work on in Westminster
- Server and comms room cooling
- Ceiling cassettes
- VRF systems
- Wall-mounted split systems
- Ducted systems
- Multi-split systems
After we’ve gone
Looking after it is simple, and it makes the next visit easier:
- Book a maintenance contract to keep servicing on schedule
- Plan the air conditioning alongside the fit-out
- Avoid units heating and cooling the same space
Handover includes a walk-through of the controls so staff can set it up properly. Simple settings make a real difference to comfort and running.
Make sure filters are maintained and outdoor units have space. Restricted airflow puts strain on the whole system.
What else we do in Westminster
Common questions in Westminster
Do you cover Westminster for commercial air conditioning?
We do: Westminster falls inside our working area. To start, call us on 07833 053749 or use the quote form with a few pictures.
Can I fit air conditioning in Westminster without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Westminster sits inside the Broadway and Christchurch Gardens Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Westminster council, which is normally the planning authority for Westminster.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and we hold it.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Is there a survey before the work?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
A customer’s words
“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.”
