Drainplumb is a plumbing and drainage business, which matters for air conditioning in London because half the job is pipework. The condensate run, the refrigerant lines and the electrics all have to be planned together, not bolted on afterwards.
The Short Version
- Split or multi-split, and which suits a flat or a house
- Where the outdoor unit can go in a mansion block or terrace
- How the work is staged so the rest of your home carries on
- What happens from the first call to the written price
Drainplumb is a plumbing and drainage business covering London, and the same plumbing skills that go into drain unblocking in London go into planning a condensate run that drains properly. You describe the job at no charge and get a written price before any work starts.

Air Conditioning Installation and System Types
Split and multi-split systems in London homes
Most air conditioning jobs in London come down to two choices. A single split system cools one room, with an indoor unit on the wall and an outdoor unit outside. A multi-split runs several indoor units from one outdoor unit. That's the decision for most flats and houses, and it's worth settling before anyone picks up a drill.
Why the building decides the system
A Victorian terrace in Clapham and a modern flat in Stratford don't want the same install. Period houses often have little wall space for pipework, and a mansion block in Kensington can limit where an outdoor unit goes. You'll want that unit somewhere it can breathe and where it won't bother the neighbours.
Condensate and electrics come first
Every system makes water, so the condensate has to drain somewhere sensible. The unit also needs a proper electrical supply. Both get settled before any unit goes up, because they're hard to fix afterwards. That's the order we work in.

Residential and Commercial Air Conditioning Solutions
Houses and flats
At home, air conditioning usually means keeping a bedroom or living room comfortable through a hot summer. Terraced houses around Wandsworth often suit one or two split units. Flats in tower blocks and newer developments tend to suit a multi-split, because there's less outside wall to work with.
Shops and small offices
The same systems work for small commercial spaces, but the questions change. It's about where the units sit, how the room is used and when the work can happen around the business. If you're after air conditioning close to home in London, we cover Greater London and the towns around it.
Living with the work
Will the job take over your home? It won't. The work is staged so the mess stays in the room being worked on and the rest of the house carries on as normal. The outdoor unit and the pipework come first, then the indoor unit goes in. You'll know the plan before we start.
Installation Process and Timescales
From the first call to the written price
It starts with a call or the quote form. You describe the job at no charge, and you get a written price before any work starts. That's how it runs, start to finish. No surprises on the day.
Access near parks and period streets
London adds its own wrinkles. Properties near the Royal Parks, around Hyde Park and Kensington Gardens, sit among dense development, so an air conditioning install there can need careful access planning. The condensate run is a plumbing job too, so a local plumber in London can handle that part alongside the units.
Timescales
We won't put a timescale on a job until we've seen the property. It depends on the system, the building and the access. What we can tell you is the order: survey, pipework, units, then testing. Describe the job and we'll put a written price to you.

People Also Ask: Air Conditioning in London
Is it legal to install AC in London?
It depends on the building. Flats, leasehold properties and listed buildings can carry extra rules from the freeholder or the council, so it's worth checking before a unit is fitted. Tell us about the property when you describe the job and we'll work from there.
Can air conditioning go into a Victorian terraced house in London?
Yes, and it's common. Period terraces often have limited wall space, so we look at where the pipework can run and where the outdoor unit can sit. A single split or a small multi-split usually suits. It comes down to the layout.
Where does the outdoor unit go on a flat in a mansion block?
That's often the hardest part. A balcony, a rear wall or a roof space might work, but the building's rules and the neighbours matter. We'll look at the options once you've described the property. Nothing is fitted until the plan is agreed.
What's the difference between a split and a multi-split system?
A split system serves one room from one outdoor unit. A multi-split serves several rooms from a single outdoor unit, which helps where outside wall space is short, as in many London flats. Which one fits depends on how many rooms you want cooled.
Does air conditioning need a drain?
Yes. Cooling makes condensation, and it has to drain away cleanly. We plan that run before the units go up, because a poor fall or a blocked line causes leaks later. It's plumbing, which is what we do.
How do I get a price for air conditioning in London?
Call 07401 062636 or use the quote form and describe the job. There's no charge for that. You'll get a written price before any work starts, so you know what you're agreeing to.
