Air conditioning in Kingston and Surbiton

Fitting air conditioning in Kingston and Surbiton

Air conditioning installation in Kingston and Surbiton 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

Kingston’s contractor parking permit is for building work lasting over 3 weeks, so most fittings won’t qualify. We’ll ask about parking on your street when we book.

Servicing and repairs

Servicing and repairs cover all of Kingston and Surbiton, 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 Kingston and Surbiton

Air con makes we fit in Kingston and Surbiton 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 Kingston and Surbiton

Shops, offices and restaurants in Kingston and Surbiton should have noise evidence ready before they apply, because many sit beside or under homes. The census counted about 930 Kingston households over a shop, or in an office or hotel building. The highest numbers are in Kingston Riverside, Surbiton North and Tolworth.

That applies on each of the borough’s main shopping streets:

• Kingston town centre, the largest
• Surbiton, around Victoria Road, Brighton Road and Maple Road
• New Malden, with its Korean restaurants
• Tolworth town centre

One KT2 business won approval in November 2022 with a noise assessment. The permission keeps the units quieter than the background noise at the nearest homes.

Semis, side passages and the 2025 rules

Semi-detached homes are Kingston’s commonest kind of home, at 31.7% of households against 18.6% across London. A semi can usually take one heat-and-cool unit without a planning application, if it stays within the national limits.

The 2025 rules made that easier here. Until 29 May 2025, those limits ruled out any spot within 1 metre of the boundary, which shut out a narrow side passage. That gap rule has gone, so a side passage can now qualify.

The other limits still apply, and noise matters most down the side of a semi. The unit must pass the MCS 020(a) sound calculation, and a side passage can put it close to next door’s windows.

A fence and gate can hide a side unit well, and Kingston officers have accepted that on looks. Noise near a neighbour’s bedroom window is the point to get right, so we include it from the start.

So the survey compares the side passage with the back wall. We check the unit gets enough air and the passage stays clear to walk through. If next door’s bedroom window faces the passage, the back of the house may suit better.

Where an outdoor unit works best, and the limits in full.

Planning for air con in Kingston

Kingston Council has approved most of the air con put to it: 14 of 16 applications over the five years to October 2026.

Good noise evidence is the main thing to have ready here, for homes and businesses alike.

Allow about 10 weeks for a decision. The median was 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.

Semis in the south, flats by the river

Semis in the south and flats by the river give Kingston two planning routes. Houses make up 61.5% of households, and flats about 38%. A house may have rights to fit a heat-and-cool unit, within limits. A flat usually needs an application as well as the freeholder’s yes. What to agree with a freeholder.

The job changes from one neighbourhood to the next:

• Berrylands South, Hook and Motspur Park: semis are 75%, 56% and 49% of households. With one unit allowed on a semi, several rooms usually means a multi-split.
• Tolworth and Chessington: the draft Local Plan says 1930s semis mark the south of the borough, but Chessington North leans to terraces, at 60%. A mid-terrace has no side passage, so the unit usually goes at the back.
• Surbiton: over half of households in Surbiton North and Surbiton South live in purpose-built flats. Converted flats reach 22% in Surbiton North. Victorian and Edwardian streets lie next to the town centre, so look for a conservation area too.
• Kingston Vale and Coombe Hill: 53% of homes are detached, the most in the borough, and national rights allow two units on those. Conservation areas here include Coombe Hill, Coombe Wood and Kingston Vale.

Summer heat in Kingston’s flats

Summer heat in Kingston weighs most on flats and the densest streets, though outer London runs cooler than the centre. A 2024 study for the GLA found flats more prone to overheating than houses, with hot spots inside every borough. The draft Local Plan adds that densely built parts of Kingston can be warmer.

So the need is likely to be greatest in blocks such as those in Surbiton South, Surbiton North and Kingston Riverside. Over half of households there live in purpose-built flats.

Air con isn’t always the first step. The draft Local Plan wants natural cooling explored first, such as outside shading and blinds. If those settle the room, you don’t need a unit.

If they don’t, the survey looks at each hot room, its size and where the sun falls, and we size the system from there. If you rent, your landlord has to agree first. Options if you rent.

Kingston gets about 5 days a year above 30C in Met Office modelling for 2001 to 2020. That rises to about 10 at 2C of global warming, within a range of 4 to 15. What the next ten years could bring.

Conservation area guidance on outdoor units

Conservation area guidance in Kingston names air conditioning units. The council wants them at the rear, below the eaves and out of sight from the street. They shouldn’t rise above the roofline either. The council weighs this guidance when it decides an application, and it covers all 26 conservation areas.

National rights also differ in those areas. They leave out a wall or roof facing a road, and any spot nearer the road than the house.

None of Kingston’s three Article 4 directions deals with outdoor units. The draft Local Plan, which could be adopted in 2028, says a heat pump on a historic building must be sited to avoid harm.

A few homes will have no spot that passes, and a fixed outdoor unit isn’t the right fix for those. Options with no outdoor unit.

Shops and offices in the town centre

Shops and offices in Kingston’s Old Town do best with plant kept out of public view. The council’s proposals for the Old Town ask that outside plant doesn’t harm the area or a listed building.

The back of a building counts there too. The same document mentions rear walls facing All Saints’ churchyard, so we look at those views as well.

Those proposals date from 2006 and rest on an older plan, so read them as guidance. The council’s Old Town page still lists them, so ask the council before you order plant. Fitting around your opening hours.
