Discreet air conditioning in Knightsbridge
Apex designs and fits air conditioning in Knightsbridge for mews houses, mansion flats, townhouses, shops and offices. The aim is usually comfort you can feel but not see, with outdoor units hidden on roofs, in lightwells or behind a mews. Olly surveys free of charge and quotes a fixed price in writing.

Hidden air con for Knightsbridge interiors
In a finished flat or townhouse, many owners do not want a wall unit on show. A ducted system hides the indoor unit in a ceiling void or cupboard and feeds each room through slim grilles.
Airzone controls then give each room its own temperature. Where there is no ceiling void, a low floor console can take the place of a radiator, or a cassette can sit flush with the ceiling.
Which one works comes down to three things: ceiling depth, where the condensate drain can run, and how far the outdoor unit is from the rooms. We check all three at the survey. See ducted air conditioning for how concealed systems are planned.
Mews houses, lightwells and roof space
Outdoor units in Knightsbridge usually go on a flat roof, in a lightwell or rear yard, or at the back of a mews. A lightwell is often the only option, but sound bounces off its walls and neighbours' windows are close.
The MCS 020(a) calculation sets a limit of 37 dB(A) one metre from the nearest neighbouring window, so a quieter unit, anti-vibration mounts or an acoustic screen may be needed to stay under it.
On a flat roof, a unit must stay at least a metre back from the edge to count as permitted development on a house, and it needs clear air around it to run efficiently. We also plan how an engineer will reach it safely for servicing in years to come.
Not sure which unit suits your Knightsbridge home? A couple of photos usually settles it.

Estate, freeholder and planning consents
Most of Knightsbridge is covered by conservation areas, including Knightsbridge, Knightsbridge Green, Albert Gate, Hans Town, Belgravia and Brompton, and many buildings are listed. Leasehold homes on the large estates and in mansion blocks also need the landlord's or managing agent's consent for outdoor units and new holes in the walls.
We draw up where the unit will sit, how the pipes will run and the noise figures, ready to go with each application. Our guide to planning for air con explains the rules.

Shops and offices in Knightsbridge
Shop condensers generally go in a back yard or on the roof behind the shopfront. On a busy shop floor with warm display lighting, a ceiling cassette spreads air evenly without taking up wall or display space. Our London commercial work includes ducted heating and cooling on a City office floor and Daikin VRV systems.
Parts of Knightsbridge fall under Westminster and parts under Kensington and Chelsea, so we confirm which council covers your address before any application. See office and shop air conditioning.

What our customers say
Word for word from Checkatrade and Google.
From initial contact to completion of install and subsequent aftercare, my experience with Apex was top class. The install itself was done in half a day and the room was left clean and tidy - you’d not know engineers had worked there! Not often I recommend someone, but I’ve passed their details on to friends who have used them and all had the same personal and great experience.
First class service! Ollie is very knowledgeable, provided a thorough service and deep clean of all our units and fixed a leak.
Had three units installed now and cannot fault either the equipment or Apex, from the initial unbiased advice, through to installation, I have no complaints whatsoever. Would recommend to anyone
Questions
Air conditioning in Knightsbridge: questions
Can air conditioning be hidden in a Knightsbridge flat?
Often, yes. A ducted unit can sit in a ceiling void or cupboard with only small grilles showing in each room, and the outdoor unit can go on a roof or in a lightwell. You need enough ceiling depth for the unit and a fall for the condensate drain. Where that is not possible, a floor console or flush cassette is the next most discreet choice.
Can the outdoor unit go in a lightwell?
Usually, if it passes the noise check and the freeholder agrees. Lightwells are enclosed, so sound reflects and the neighbours' windows are close by. We calculate the level at the nearest window against the 37 dB(A) limit, then choose a quiet model or add screening if needed. The unit also needs enough free air around it to work properly.
Do I need permission for air con in a Knightsbridge mews house?
Probably, in some form. Most of Knightsbridge is in conservation areas, so a unit facing the mews usually needs planning permission, and a listed house needs listed building consent. If the house is leasehold, the landlord must agree too. A unit on a rear flat roof is often the simplest route. We check each of these at the survey.
Do you cover Knightsbridge from Dartford?
Yes. We drive up from Dartford, roughly 17 miles, and work across central and west London, including Belgravia, Chelsea, Brompton and South Kensington. For London jobs, WhatsApp photos of the rooms, the ceilings and the back of the building help Olly plan the free survey before he arrives.
