Air conditioning in Kensington and Chelsea

Fitting air conditioning in Kensington and Chelsea

Air conditioning installation in Kensington and Chelsea starts with a survey of your rooms and your building. We check the unit size, the pipe route and where the outdoor unit can go, then you get a written quote. How an installation works.

A single split cools one room, and a multi-split runs several rooms from one outdoor unit. Fewer outdoor units means less to place, which helps on a terrace or in a flat. Most split units heat as well as cool, so one system can do both jobs.

A few things make the survey quicker:

• a list of the rooms you want cooled
• your lease, if you live in a flat
• the name of your conservation area, if you’re in one

Parking bays in Kensington and Chelsea can be suspended for a job. A permit bay needs 10 working days’ notice, and a pay-by-phone bay needs two. We’ll raise this at booking if a van or lift needs a bay.

Most units heat as well as cool. How air con can heat your home.

Servicing and repairs

Servicing and repairs cover all of Kensington and Chelsea, whoever fitted your system. A service keeps it clean and running well, and a repair visit finds out why it has stopped cooling or shown a fault. What a service covers and how a repair visit works.

A unit that has stopped cooling is worth a quick check before you book:

1. Set the mode to Cool, and the temperature below the room’s.
2. Check the remote’s batteries and any timer.
3. Clear anything from around the outdoor unit.

Ice that comes back, water dripping indoors or an error code all need an engineer. Why air con stops cooling.

Air con makes we fit in Kensington and Chelsea

Air con makes we fit in Kensington and Chelsea include the nine below, and we’ll suggest the one that suits your rooms. We service and repair these makes too, whoever fitted them. The make and model are on a label on the indoor unit, so have them ready when we call.

More homes are fitting air con

More UK homes are fitting air conditioning, and homes with built-in units have about doubled in three years. The best time for a survey is before the first hot spell, when fitters have more room in the diary.

Shops, offices and restaurants in Kensington and Chelsea

Shops, offices and restaurants in Kensington and Chelsea should expect their plant to need planning permission. The Local Plan says so directly for the plant behind an evening use, such as a restaurant or bar. Around 1,000 households here lived over a shop, or in an office or hotel building, in 2021. Brompton and Portobello had the most.

Neighbours are close in all the borough’s main centres:

• Knightsbridge, an international centre
• Kensington High Street and King’s Road (East)
• South Kensington, Brompton Cross and Earl’s Court Road
• Notting Hill Gate, Portobello Road and Westbourne Grove

A kitchen has a rule of its own. Where cooking smells are significant, the plan says the extract should end above the eaves.

Showing the need for cooling in Kensington and Chelsea

Kensington and Chelsea Council asks anyone proposing air con to explore passive cooling first, even for a single unit. Its Local Plan 2024 says the cooling hierarchy applies at every scale of development.

The cooling hierarchy is London’s ranked list of ways to keep a building cool, and air con comes after passive steps. For heritage buildings, the council’s greening guide points to blinds and shutters first.

Officers apply this to homes, so an overheating assessment matters. An SW3 job approved in April 2026 shows what passed:

• an overheating assessment, showing passive steps still left a risk
• an acoustic report, checked by the council’s noise team
• a discreet spot in the rear yard, behind an acoustic screen
• a fire safety statement, which the plan asks for on minor applications

Noise has its own test. The council expects a report from a member of the Institute of Acoustics whenever outside plant is proposed. Its usual condition says plant must not raise the lowest background noise at any time it runs. That’s judged at the nearest window, and at any garden, terrace or balcony next door. Units must also stand on anti-vibration mounts.

An acoustic box has to look right too, as the noise guide makes clear. The plan counts plant as a small-scale addition, which must be discreetly located. The council’s heat pump guide says units shouldn’t go on street-facing walls, or on terraces, roofs or balconies seen from the street.

Allow for these papers before you choose a system. At the survey we note which rooms overheat and what shading is in place, which helps whoever writes the assessment. If shading or ventilation solves it, air con isn’t the right fix. What to try first.

Planning for air con in Kensington and Chelsea

Kensington and Chelsea Council approves most air con when the evidence stands up: 334 of 362 decided applications over the five years to October 2026. For all planning applications it approved 93% in the year to June 2026, against 87% across England.

With 885 applications to sort, we used a wording rule and checked samples by hand, so treat these counts as close, not exact.

Noise evidence matters most here, so these go into the plan early:

• Fresh readings: an up-to-date noise survey.
• Listed homes: an acoustic assessment, with outside pipework kept neat.
• Night-time figures: readings the council can rely on.

Applying before fitting helps too: 305 of the 323 applications made first were approved.

Decisions took a median of 68 days, about 10 weeks, where the target is 8 weeks.

These are past results, not a promise for your home. They count people who applied, and many units never need an application.

We check the planning route at the survey. If you need to apply or ask a freeholder, we supply the drawings and the unit’s data.

Mansion blocks, converted houses and listed terraces

Mansion blocks and other flats hold 83% of households in Kensington and Chelsea, against 54% across London. Purpose-built blocks take 57%, converted houses take another 24%, and houses come to just 17%.

The Local Plan draws the planning lesson itself. It says mansion blocks lack a house’s permitted development rights, and that the council gets many applications from them. It also wants a consistent approach across a whole building. Nearly three quarters of the borough sits in 38 conservation areas as well. Getting a freeholder’s yes.

The job changes with the building:

• Purpose-built blocks: about 7 in 10 households in Earl’s Court and Brompton. The council’s heat pump guide says a unit for every flat may be impractical in a larger block. So speak to neighbours and the managing agent early.
• Converted houses: about 4 in 10 households in Portobello and North Kensington. The same guide says a building with a few flats may manage a unit each. It rates the rear garden first, and says sound can echo in a side return.
• Listed terraces: the council’s guide says you’ll apply for planning permission and listed building consent together. Plan the pipe route early, because officers look at materials and the detail on the inside fabric.
• New basements: the plan wants plant sensitively designed and discreetly sited. The basements guide says it should ideally sit inside the building, so design it in from the start. Ways to hide a unit.
• Cadogan land in Chelsea: a lease usually needs consent for alterations, so check yours early. Cadogan’s guidelines ask for the position of all outside plant, and an acoustic engineer’s report with any air con application.

The council says it can’t weigh land ownership, so its yes doesn’t replace a freeholder’s.

Heat need in North Kensington and Chelsea Riverside

Heat need in the borough peaks in North Kensington, with a smaller rise at Chelsea Riverside. That’s the pattern on City Hall’s climate risk map, which weighs income, age and tree cover alongside temperature. Our sample of its scores ran like this:

• Highest: Golborne, Notting Dale and Colville
• Next: Dalgarno and Chelsea Riverside
• Lowest: Campden and Queen’s Gate

The council’s own response shows the same need. During the Red heat-health alert of June 2026, it sent over 250 cool kits to older people and young families in North Kensington. It also kept lift contractors on standby in higher-risk blocks.

The Local Plan says heat risk matters most in densely built boroughs like this one. In a flat with no outside space, the survey starts with where a unit could go at all, then which room to cool. A tenant needs the landlord’s agreement in writing first. Options if you rent.

A typical year here had about 5 days above 30C in 2001 to 2020, on Met Office figures. At 2C of warming the model shows about 10, and the range runs from 5 to 15. The Climate Change Committee expects around 2C by 2050. What the next ten years could bring.
