Air Conditioning in Wimbledon

Wimbledon asks more of an air conditioning design than anywhere else we work, for two reasons that pull in opposite directions. The houses are large, which means multi-room systems and real cooling loads. And Merton has 28 conservation areas, several of them covering the most desirable parts of SW19, which sharply limits where the outdoor plant can sit. A big system with nowhere to put the condenser is not a design, it is a problem.

The rooms that need it are predictable. Loft conversions in the Village and around Wimbledon Park, which sit under the roof and become unusable in July. South and west-facing bedrooms in the large Victorian and Edwardian villas, where high ceilings and tall sash windows admit a great deal of afternoon sun. And home offices, which in this postcode are frequently in the least thermally sensible room in the house. A single condenser can serve up to five indoor units, so the sensible answer here is usually one multi-split system rather than four separate installations and four outdoor boxes.

That matters more in Wimbledon than elsewhere precisely because of the planning position. One correctly sited condenser is a conversation you can have with a conservation officer. Four of them, on a house in the Wimbledon Village or John Innes Merton Park conservation areas, is not. We design for the minimum external footprint from the start rather than adding units one summer at a time.

Local Detail

Designing Around Merton's Rules

Four constraints shape almost every Wimbledon air conditioning job, and none of them are about the equipment.

28 Conservation Areas Across Merton

Wimbledon Village, Wimbledon North, Wimbledon West, Wimbledon Hill Road, Wimbledon Broadway, Wimbledon Chase and the Windmill area are all designated, as are Copse Hill and Westcoombe Avenue in SW20. Permitted development still applies inside them, but the outdoor unit must not sit on a wall or roof fronting a highway, nor nearer a bounding highway than the building. On a detached villa set back from the road that is workable. On a corner plot it takes thought.

The John Innes Article 4 Direction

The John Innes Merton Park conservation area has carried an Article 4 direction since 1986, which removes permitted development rights that apply elsewhere. External alterations there, an air conditioning condenser included, need closer scrutiny and may require a formal application. If your property is on the John Innes estate we establish its exact status before quoting rather than assuming permitted development covers it.

One Condenser, Not Four

A multi-split system runs up to five indoor units from a single outdoor condenser, each controlled independently. In a conservation area that is not merely tidier, it is often the difference between a scheme that is acceptable and one that is not. It is also cheaper than four separate single-splits once you are past two rooms, and it is why we would rather design the whole house at the survey even if you only fit half of it this year.

Conversions, Mansion Blocks and Freeholder Consent

A great deal of SW19 is flats carved out of larger villas, plus the purpose-built mansion blocks near the station. For a flat the outdoor unit is capped at 0.6 cubic metres rather than 1.5, and the lease will normally require the freeholder's written consent before anything is fixed to the building. Some leases prohibit it outright. We read the position at the survey and tell you before you spend anything.

Common Questions

Air Conditioning in Wimbledon FAQ

Can I install air conditioning in a Wimbledon conservation area?
In most cases yes. Permitted development still applies inside a conservation area, but the outdoor unit must not be fitted to a wall or roof that fronts a highway, nor sit nearer to a bounding highway than any part of the building. Merton has 28 conservation areas and most of central Wimbledon falls in one, so the condenser position is decided early in the design rather than late. We confirm your property's designation at the survey.
What does the John Innes Article 4 direction mean for air conditioning?
The John Innes Merton Park conservation area has had an Article 4 direction since 1986, which strips out permitted development rights that would apply elsewhere. In practice external alterations there, including an air conditioning condenser, get closer scrutiny and may need a formal application rather than being automatically permitted. If you are on the estate we check the exact position before quoting and tell you what is required.
Should I fit one multi-split system or several separate units?
In Wimbledon, almost always one multi-split. A single outdoor condenser can serve up to five indoor units, each independently controlled. Past two rooms it costs less than separate systems, and far more importantly it means one piece of external plant rather than four, which in a conservation area is frequently the difference between a scheme that gets through and one that does not. Even if you only fit two rooms now, design the whole house at the survey.
Can you cool a loft conversion in Wimbledon Village?
Yes, and it is the most common request we get in SW19. A loft room sits directly beneath the roof with roof windows admitting sun for most of the day, and it holds that heat overnight. A single wall-mounted indoor unit brings it down in minutes. The work is straightforward; the part that needs planning is where the condenser goes, particularly on a Village property inside a conservation area.
I live in a Wimbledon flat or mansion block. Is air conditioning possible?
Often, but two things decide it. The outdoor unit for a flat is capped at 0.6 cubic metres rather than the 1.5 allowed on a house, and your lease will almost certainly require the freeholder's written consent before anything is attached to the building. Many of the conversions and blocks around the town centre are strict about it and some leases prohibit it. We establish the position at the survey rather than after you have committed.
Will the outdoor unit annoy my neighbours?
Not if it is sited properly, and that is a design decision rather than a product one. MCS 020a, which the installation has to comply with, sets a noise limit assessed at the nearest neighbouring window, and on the closely spaced plots common in parts of Wimbledon that assessment genuinely constrains where the unit can go. We work it out at the survey rather than discovering it afterwards.
Can you work around the Championships fortnight?
Yes, and we plan for it. Access and parking around Wimbledon Park and the streets near the grounds are heavily restricted for roughly two weeks from late June, which is not the time to be carrying condensers and refrigerant pipework into a house. If your job falls near that window we either book clear of it or agree access with you well in advance.
Which parts of Wimbledon and Merton do you cover?
All of SW19 including Wimbledon Village, Wimbledon Park, South Wimbledon and Wimbledon Chase, and all of SW20 including Raynes Park, West Wimbledon and Cottenham Park, plus the rest of Merton: Merton Park, Colliers Wood, Mitcham in CR4 and Morden in SM4.
