Air conditioning in Wimbledon

Fitting air conditioning in Wimbledon

Air conditioning installation in Wimbledon 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

During Wimbledon fortnight, parking restrictions cover Wimbledon Village, Wimbledon Park and parts of the town centre. We’ll ask about your street when we book, and another week may suit better.

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

Servicing and repairs

Servicing and repairs cover all of Wimbledon, 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 Wimbledon

Air con makes we fit in Wimbledon 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 Wimbledon

Shops, offices and restaurants in Wimbledon need their plant planned around the neighbours, because Merton wants it kept away from homes where possible. Merton has about 1,000 households living above shops or in office or hotel buildings, the census found. The highest numbers are in Raynes Park, Morden Central and Wimbledon Broadway South.

Plant near homes is a question in each of these centres:

• Wimbledon town centre, the borough’s main one
• Wimbledon Village
• Raynes Park
• Morden
• Mitcham
• Colliers Wood

In 2022 one SW19 premises won approval for two condensers in acoustic enclosures in its rear car park, along with a new timber shopfront.

A shop may not need air con at all. Merton’s shop front guide says an openable fanlight, perhaps with an awning, can remove the need for it.

How commercial jobs work.

Sources: Census 2021, table TS044, Merton’s Local Plan, policy P15.10, Merton’s planning register and Merton’s shop front guide (2017), paragraph 8.1.57. The census is taken every 10 years.

Merton’s noise assessment for new units

Merton’s Local Plan expects a noise assessment of any new plant and equipment, and we read that as covering an air con outdoor unit. It also wants plant kept away from homes, schools and other sensitive places where possible. The plan was adopted on 20 November 2024, and applications validated after that date are judged against it.

Policy P15.10 asks applicants to:

• assess the plant’s effect on neighbours and on the background noise
• add measures where noise needs controlling
• accept limits on hours where noise can’t be brought down far enough

This matters when you need to apply, which is common in Wimbledon’s flats and conservation areas. A heat-and-cool unit under national rights has its own sound calculation instead.

Merton’s own decisions show what the test leads to. Of the 35 approvals in the next section, 5 name an acoustic enclosure, housing, screen or grille. One of those boxes takes up room, because the unit still has to breathe. So we look for a quieter spot before we reach for a box.

The plan promises a Noise and Vibration planning document with Merton’s exact requirements. It wasn’t on the council’s guidance list on 31 October 2026. Until it is, you can ask through the council’s pre-application advice service.

A home with no quiet spot shouldn’t have a fixed outdoor unit. Choices with no outdoor unit, and how loud air con is.

Planning for air con in Merton

Merton Council approves nearly all the air con it decides. Over the five years to October 2026, it approved 35 of 38 planning applications mainly for air con or similar units. For all planning applications it approved 91% in the year to June 2026, against 87% across England.

Most of these cases, 30 of the 38, were in SW19.

A decision takes about 10 weeks, with a median of 68 days against an 8-week target.

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.

Big Victorian houses, split into flats

Big Victorian houses split into flats shape much of Wimbledon, and that sets the planning route. Many of the largest were divided or replaced by blocks during the Second World War. Across Merton, 60% of households are in houses and 40% in flats. Those houses may qualify for national rights, within limits. Most flats can’t, so expect an application and a freeholder’s yes. What a freeholder needs to see.

Four parts of the borough show how the job changes:

• Wimbledon Broadway North, Colliers Wood and Wimbledon Chase: 18% to 23% of homes are flats in converted houses, about double Merton’s 9%. Plan the pipe route with upstairs and downstairs neighbours in mind.
• Wimbledon Common: detached homes reach 39%, Merton’s highest share. A detached house can have two units under national rights. Conservation areas such as Wimbledon West and Wimbledon North still limit spots facing a road.
• Merton Park: Article 4 directions in the John Innes conservation areas remove rights for some homes, including over gates, fences and walls. So a screen around a unit could need an application.
• Morden and Lower Morden: low-rise suburban streets, with Lower Morden 58% terraced. A mid-terrace has one wall to the garden, so the back is the likely spot.

One-sided flats and summer heat

One-sided flats can be the hardest homes to keep cool in Merton’s summer heat. The Local Plan says homes with windows on one side can be harder to ventilate, and may overheat more easily. The GLA’s 2024 study points the same way, rating flats as more at risk than houses, with hot spots in every borough.

So the need is likely to be greatest in the blocks. Purpose-built flats house about half of Wimbledon Hill and of Merton Church Road & Phipps Bridge. The Character Study adds that Raynes Park lacks open space away from its big green spaces to the north, and calls for street greening.

Shade and airflow come first in Merton’s own thinking, as its plan puts passive cooling ahead of air con in new buildings. In an existing home, it makes sense to start there. Cheaper steps to try first.

At the survey we note which way your rooms face, because that shapes how much cooling each one needs.

Expect about 5 days a year above 30C in Merton, on Met Office modelling for 2001 to 2020. At 2C of global warming that doubles to about 10, within a range of 5 to 15. What the next ten years could bring.
