Air conditioning across the City of Westminster
Yes, you can have air conditioning fitted in Westminster, even in a listed or period property. The real skill is doing it discreetly and within the council’s rules, which is what our engineers handle across the borough every week.
Westminster is unlike anywhere else to work. Most of the borough sits inside a conservation area, and there are thousands of listed buildings, from Georgian townhouses to grand mansion blocks. A bulky box bolted to a front wall is rarely allowed, and rarely wanted.
Each system is designed around the building. Our engineers look at the layout, the power supply, the drainage and where any outdoor unit can sit out of sight, then choose a system that performs well and stays hidden. That work runs right across Mayfair, Marylebone, Belgravia, Pimlico, Victoria, St James’s, Soho, Paddington, Maida Vale and St John’s Wood.
Do you need planning permission for air conditioning in Westminster?
In many cases, yes. Because most of Westminster is a conservation area, the permitted development rights that cover air conditioning elsewhere are often restricted or removed.
If your property is listed, you usually need listed building consent as well as planning permission before any unit goes in. Some streets also carry an Article 4 direction, which removes permitted development rights completely, so even a small unit needs an application.
Westminster sets strict limits on plant noise too. A unit often has to run at around 10 decibels below the background noise on the street, which means careful unit choice and positioning. It sounds like a lot to weigh up, but it is routine for our team. Engineers advise on what your property allows and recommend a system that meets the rules. You can also check the basics on Westminster City Council’s planning guidance
Can you install air conditioning in a listed or period property?
Yes. For listed buildings, or homes where no external unit is allowed, we fit internal water-cooled systems that need no outdoor box at all.
A water-cooled system sits entirely inside the property. It uses your mains water and drainage to move heat, so nothing is fixed to the outside wall and the facade stays untouched. For a listed building or a strict freeholder, this is often the only route that gets approved.
Where an outdoor unit is allowed, it gets hidden. Cool air can come through slim ceiling grilles using ducted air conditioning, while pipework runs through voids and risers out of sight. For flats and single rooms, a multi-split system links several indoor units to one discreet outdoor unit, and a single wall-mounted unit suits one room.
What air conditioning services do you offer in Westminster?
From the first survey to long-term servicing, RightAir handles the whole job in Westminster, so you never need a second contractor.
Installation
New air conditioning for homes and businesses, sized to the room and the building. Each system is designed around period features and the council’s rules, not around an off-the-shelf box. See residential air conditioning.
Servicing and maintenance
A yearly service keeps your system efficient and your warranty valid. This is popular with owners in Mayfair and Marylebone who run their systems all year for both heat and cool. See air conditioning maintenance.
Repairs and emergency
Fast fault-finding when a system stops cooling, leaks or makes a noise. Our engineers repair all major brands, even systems we did not fit. See air conditioning repair.
Do you cover commercial properties in Westminster?
Yes. Westminster is full of offices, hotels, shops and restaurants that depend on reliable cooling, and many of them are on our books.
For workplaces around Victoria and Soho, comfortable air keeps staff and customers happy. For Mayfair hotels and central retail, the system has to be quiet, discreet and always running. RightAir also issues TM44 inspection reports, the legal check required on larger commercial systems, and plans installs around your trading hours to keep disruption low. See office air conditioning and hotel and hospitality air conditioning.

How much does air conditioning cost in Westminster?
The cost of air conditioning in Westminster depends mainly on the type of system and how many rooms you want to cool.
A single wall-mounted unit in one room is the simplest job. A multi-room or ducted system costs more, and a fully internal water-cooled system for a listed building sits at the higher end because of the extra design work involved. Other things that affect the price include:
- Access to the property and how the pipework can be routed
- The age and structure of the building, and whether existing pipework needs upgrading first
- Whether a discreet or fully internal system is needed to meet planning rules
- In older Westminster properties our engineers often find the existing routes need work before a clean install is possible, which the survey will flag early.
Qualifying domestic installations can currently be zero-rated for VAT until 31 March 2027, because HMRC treats most fixed air conditioning units as air source heat pumps. Ask us whether yours qualifies. Every survey and written quote is free, with no obligation and no hidden charges.

Air conditioning questions Westminster clients ask
Got a question? Just ask. Here are the ones we hear most.
Yes. The systems we install are air-to-air heat pumps, so they warm a room as well as cool it. Many Westminster owners run theirs all year and heat one room at a time to keep costs down.
No. Each route is planned to avoid harm to original features, with careful drilling methods on solid brick and stone. For listed buildings, internal water-cooled systems need no external work at all.
Most domestic installs are finished in a day, sometimes two for larger systems. Floors and furniture are protected, communal areas kept clean, and timings agreed with you in advance.
A survey can usually be arranged within a few days. For breakdowns, same-day callouts are available where possible.
Yes. Our engineers service and repair all major brands, including Daikin, Mitsubishi Electric and Fujitsu, whoever fitted them first.
A well-fitted system that is serviced each year typically lasts 10 to 15 years. Regular servicing keeps it efficient and protects the warranty.
Coverage runs across the whole City of Westminster. That takes in Mayfair, Marylebone, Fitzrovia and Soho in the W1 postcodes, Belgravia, Pimlico, Victoria and St James’s in SW1, and Paddington, Bayswater, Maida Vale and St John’s Wood to the north and west.
Neighbouring areas are covered too. If you sit just outside the borough, see our Central London air conditioning page, or our Kensington air conditioning page for properties to the west.
