Air conditioning in Clapham and nearby

When it’s something else

Air conditioning cannot fix everything, and we’d rather say so up front. It does not solve:

  • Gas boiler or central heating faults (we do not work on gas boilers)
  • Draughts and missing insulation
  • A ventilation problem rather than a temperature problem

If you’re not sure, just ring 07833 053749, or email if that’s easier and we’ll give you a straight answer.

What we work on in Clapham

  • Multi-split systems
  • Wall-mounted split systems
  • Ducted systems
  • Air-to-air heat pumps
  • Ceiling cassettes
  • VRF systems

Air conditioning in Clapham, done properly

Most air conditioning needs its own electrical supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. When someone in Clapham asks us for air con, the first questions are normally price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.

Space outside is often tight in Clapham, as in much of London, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. Neighbours’ windows and noise matter as much as appearance when we choose the position, and the pipe run is planned to be short, neat and out of the way.

The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

How the visit works

We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. For a job in Clapham, tell us about parking, permits and access to the building when you get in touch.

  1. We start by looking at the rooms, the walls and where the outdoor unit can go.
  2. Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
  3. The units go up and the pipework, cable and condensate drain are run neatly between them.
  4. Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
  5. Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.

Before we arrive

  • Tell us about any building rules, permits or sign-in
  • Make sure someone can let us in at the agreed time
  • Give us access to the outside wall, roof or yard where the outdoor unit sits

Common problems we fix in Clapham

Bedrooms that are too warm at night are a frequent reason for a call. Once a bedroom has soaked up heat during the day, opening a window may not bring the temperature down far enough, especially on a still night.

Common reasons people call us are:

  • Uncertainty over the right type and size of system
  • Fans and portables that don’t keep up
  • An ageing air conditioning system near the end of its life

Carlyle's House (roughly 1.9 miles north-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Air conditioning around Clapham

About 45% of homes across Clapham and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 80% of households live in flats. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. London installs often hinge on outside space, the lease and access to the building.

Older streets near St Paul's Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.

Why deal with it now?

Fans and portables move warm air around rather than removing it. A fixed system removes the heat to the outside, runs more quietly in the room and can normally heat as well, so it earns its keep all year. Getting the work done in Clapham before summer avoids the busiest weeks.

One room or a whole building, the quote is built the same way: what needs doing, how we get to it and what it needs. You will have a fixed price before any work starts, and the quote sets out the VAT.

Questions from Clapham

Is Clapham in your area for air conditioning?

Yes. We work across London and the South East from our base in East Grinstead, and Clapham is part of that. Get in touch with the details and we reply the same working day.

Will air conditioning in Clapham need planning permission?

It comes down to the building and the spot chosen for the outdoor unit. Central Clapham sits inside the Rectory Grove Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the planning department at Lambeth council, normally the authority for Clapham.

Will you work on another installer’s system?

Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.

Do you offer emergency call-outs?

Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.

How long will the installation take?

Allow a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We confirm the time when we quote, so you can plan around it.

Do I need to service the system to keep the warranty?

That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.

Do you work on all makes?

Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
