How we handle air conditioning in Westminster
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. Air con, air conditioning, a split system: whatever you call it, in Westminster it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Across London, and in Westminster too, a lot of air conditioning goes into flats and terraces rather than detached houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder normally come into it, and we can give you the details they’ll ask for.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Why act early in Westminster
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Westminster early.
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.

What affects the quote in Westminster
Every job gets its own quote. These are the things that affect it:
- One-off work versus a regular service cycle
- The condition of any existing system
- The equipment or parts the job needs
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re not sure what’s needed, ring us on 07833 053749 or drop us a line for straight advice and a fixed price.
Before you get in touch
Photos let us diagnose from a distance. The most useful are:
- The paperwork from the last service, if you have it
- The address and the type of property
- Wide pictures of the room or the existing unit
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.

Aftercare tips
Once we’ve finished, these simple steps help:
- Use moderate settings for comfort and economy
- Don’t cover or box in the outdoor unit
- Let filters dry fully before you put them back
You get the paperwork that matters: the commissioning details, the F-Gas records and the manufacturer’s warranty information. Keep them with the manual as they’re needed for servicing and any warranty question.
Use sensible settings. Choose the right mode and a comfortable temperature rather than the lowest setting and keep doors and windows shut while it runs.
What happens on the day
You don’t need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. If a freeholder or agent needs to agree the work in Westminster, we can send them the details.
- You send pictures, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- It’s switched on, checked and handed over with its records.
Before we arrive
- Clear a path to the units and the space around them
- Dig out any previous service or F-Gas records
- Mention any parking restrictions near the property

Air conditioning around Westminster
About 47% of homes across Westminster and its surrounding area were built before 1919, according to VOA council tax data, and Census 2021 figures found about 94% of households live in flats. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. In flats, the lease and the freeholder typically decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you commute from London Victoria station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed. Around Christ Church, a quick check of the listing and conservation maps is part of planning any install.
Westminster is about 1 mile south-east of City of Westminster, in Greater London.

Your questions about air conditioning in Westminster
Can you fit air conditioning in a London flat in Westminster?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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.
Can you do air conditioning in Westminster?
Yes. Westminster is one of the places we cover. To start, call 07833 053749 with a few photos.
Do you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
How long will the installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Do I get paperwork after the visit?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Is air conditioning possible in a flat?
That depends on the lease, the building and where the outdoor unit could go. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
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.”
