How we handle commercial air conditioning in City of Westminster
Commercial systems are commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, then send a fixed-price quote. That way the system fits the site and the price is clear before work starts. If the problem is staff complaining about the temperature and planning ahead for the HFC phase-down, we can sort it out.
For a business in City of Westminster, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the records and tell you what’s due.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Pricing commercial air conditioning in City of Westminster
Our prices page gives typical ranges, and your quote is built on your job. What we look at:
- Whether we need access equipment for high-level work
- Whether it’s a one-off job or part of a maintenance contract
- The size of the job
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we will explain each part.
Asking for a quote
Before you ask for a quote, gather:
- A close-up of the unit’s label showing the model number
- Photos showing the indoor unit and the space around it
- The outdoor side of the property, including any roof or flat area
For a fixed-price quote, phone 07833 053749 or send an email and tell us about the property and what you need. Photos help a lot. We reply to enquiries the same working day.
Looking after your system
To keep the system working properly:
- Agree sensible control settings for each area
- Plan regular servicing with a contract
- Keep plant areas tidy
Should anything seem off after handover, ring 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll look into it. Our 24/7 emergency line covers breakdowns.
Planned maintenance is the best way to keep a commercial system healthy. We agree the visits and the price with your quote.
Safe owner checks
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. 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.
Cooling for City of Westminster businesses
There are about 3,766 cafés, restaurants and staff canteens, about 280 hotels, B&Bs and guest houses and about 78 schools and colleges within roughly a mile and a half of the centre of City of Westminster, according to the Food Standards Agency’s register. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule. About 46% of homes in City of Westminster and the neighbourhoods around it were built before 1919, according to VOA council tax data, and Census 2021 figures found about 91% of households live in flats. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. For London businesses, plant position, noise and access are planned with the building first.
Clinics, dental practices and pharmacies around Fortius Clinic (about under half a mile north) typically want quiet indoor units with filters that are simple to keep clean. Churches and halls such as St Mark's 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.

What we do, step by step
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in City of Westminster.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- We install around your hours, phased where necessary.
- We commission it, hand it over and can set up a maintenance contract.
Getting ready for the visit
- Make sure someone can let us in at the agreed time
- 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

What else we do in City of Westminster
City of Westminster: your questions answered
Do you cover City of Westminster for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and City of Westminster is part of that. Just call us on 07833 053749 with a few details.
Is planning permission needed for air conditioning in City of Westminster?
It comes down to the building and the spot chosen for the outdoor unit. The centre of City of Westminster is in the Stratford Place Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for City of Westminster, typically Westminster council).
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
What kind of air conditioning can you install in a business?
From one wall-mounted unit to VRF across several floors. Cassettes and ducted units suit offices, shops and restaurants.
What does the operator have to do under the F-gas rules?
The operator and the service technicians share responsibility. The operator needs to arrange leak checks and keep records where the system requires them, and we provide both.
When is a TM44 inspection required?
At over 12 kW, inspections are due at least every 5 years. The inspection is done by an accredited assessor, and we do the follow-up work.
Do you offer commercial maintenance contracts?
Yes. A contract keeps the system serviced and any required leak checks on schedule and each visit is recorded.
