Air conditioning that works with your smart home, not alongside it

Most air conditioning companies fit the unit, hand you a remote control, and leave. You end up with another handset on the coffee table and a system that has no idea what the rest of your house is doing.

We came at this from the opposite direction. London Smart Homes has spent over twenty years designing and installing Control4 and KNX systems across London, so when we install air conditioning we bring it into the system you already have. Your climate control sits in the same app as your lighting, blinds and audio. It knows when a room is occupied, when you have left the house, and when you are on your way home.

One contractor designs it, installs it, commissions it and integrates it. If something is not right, there is no argument about whose responsibility it is.

Control your climate from the same system as everything else

This is the part standard air conditioning installers cannot offer. We are Control4 dealers and KNX partners, and we handle the integration ourselves rather than bringing in a third party.

  • Control4 and KNX integration — climate alongside lighting, blinds, audio and security
  • Daikin Onecta and Mitsubishi Electric MELCloud brought into one interface
  • Room-by-room scheduling that follows how you actually use the house
  • Occupancy-driven control so empty rooms are not being cooled
  • Holiday and away modes that shut everything down properly when you leave
  • Wall keypads and touchscreens instead of a drawer full of remote controls

Cools in summer, Heats in winter

Every system we install is reverse cycle, which means the same unit that cools your bedroom in July will heat it in January. It is a heat pump, and it produces several units of heat for every unit of electricity it draws.

The practical benefit is control. A loft conversion that the central heating never quite reaches, or a home office you use for three hours a day, can be brought up to temperature in minutes without firing the boiler for the entire house. For a lot of our clients that is where the running-cost saving actually comes from — not from replacing the boiler, but from not having to use it.

WHAT DO OUR CUSTOMERS SAY ABOUT US ?

S M.
London Smart Homes was exactly what we needed! Our new flat has an old Control4/Edin configuration that was left unplugged and un programmed leaving us with no working lights and a cable nightmare. Hadi understood the problem when we spoke on the phone and he came the very NEXT day and worked 4 hours nonstop to rectify and simplify the errors. His patience and professionalism is 10/10. We will continue to use London Smart Homes for any future updates and configurations.
Uday C.
★★★★★ Exceptional service and complete peace of mind Hadi helped me replace an old, out-of-date system in my apartment, and his support throughout the whole project was exceptional. He worked professionally from start to finish and updated me regularly, so I always knew where things stood. I was comfortable leaving him in my home on his own at times, which says a lot. Working with Hadi gave me real peace of mind. I would definitely use him again and recommend him without hesitation. In regards to price I don’t think any company could compete with Hadi factoring in the level of service he provides.
Rory F.
I would highly recommend Hadi at London Smart Homes. He was incredibly friendly, professional, patient and clearly very knowledgeable. We had been experiencing problems with an older Control4 system, including a disconnected remote that had left us unable to use the television in our main living room. Hadi took the time to investigate the issue, troubleshoot the system and get everything working again. Hadi explained what he was doing throughout, was happy to answer questions and had a reassuring manner that inspired confidence. He was thorough, didn't rush the job and made sure everything was working properly before leaving. A genuinely excellent service from someone who clearly knows his field and takes pride in his work. Thank you, Hadi!

Frequently Asked Questions

How much does air conditioning installation cost in London?
A single room split system typically starts from [PLACEHOLDER: FROM PRICE] fully installed, and a multi-split serving three or four rooms from [PLACEHOLDER: FROM PRICE]. The final figure depends on pipe runs, the position of the outdoor unit, and whether any making good or electrical work is needed. Every quotation follows a site survey, so the price you are given is the price you pay.
Do I need planning permission for air conditioning?
For most houses the outdoor unit falls under permitted development, provided it sits within size limits, is not on a wall facing a highway, and is at least one metre from the boundary. Flats, listed buildings and conservation areas are different and usually do need consent. We check this at survey stage and tell you before you commit.
How long does installation take?
A single split system is usually a one-day job. A multi-split serving three or four rooms typically takes two to three days. We agree the schedule with you in advance and work to it.
Will the units be noisy?
Modern indoor units are far quieter than most people expect — the Mitsubishi Electric range we install runs from 18dB on low fan speed, which is quieter than a library. Outdoor unit placement matters just as much, and we position it with both your neighbours and your own bedroom windows in mind.
Can air conditioning heat my home as well as cool it?
Yes. Every system we install is reverse cycle, meaning it works as a heat pump in winter as well as an air conditioner in summer. It gives you fast, room-by-room warmth without firing the boiler for the whole house — useful for a home office or a loft room that the central heating struggles to reach.
Can you integrate air conditioning with my existing Control4 or KNX system?
Yes, and this is what we do differently. We are Control4 dealers and KNX partners, so climate control can be brought into the system you already have rather than living in a separate app. Daikin and Mitsubishi Electric both expose their systems for integration, and we handle that work ourselves rather than subcontracting it.
