I did not think it was possible for my apartment to be air conditioned until Cool You proposed a solution. I have been extremely impressed not only by the system they fitted, but also by the speed and efficiency of Cool You.”
Guy H (Islington, London)

If your search for an air conditioning solution for your apartment in London has proved frustrating, we are here to ease that frustration.

Whilst you may have been told you can’t have an air conditioning unit in your apartment, we have the solution with air conditioning units without an outside condenser.


At Cool You UK, we are the experts in the supply and installation of high-quality air conditioning units in apartments throughout London.

None of our solutions requires an external condenser and all of our solutions are suitable for installation without planning permission.

Questions to ask yourself

  • Does your apartment sometimes get uncomfortably warm?
  • Would you like to sleep more comfortably at night?
  • Does your apartment get the afternoon and evening sun?
  • Do you work from home at least part of the working week?
  • Do you suffer from chest complaints or hay fever?

If the answer is YES to any of these questions, we can help.


Our full internal water cooled condensers make the perfect air con solution for apartments where an outside condenser box and external vents are not an option.

All components of our water cooled air con solutions are contained within the property that you wish to be air conditioned.

For aesthetic and practical reasons, we conceal the condensing box out of view. This is usually under the kitchen sink or within a storage cupboard.

For cooling and heat extraction, we utilise your apartment’s mains water and drainage system. The condenser is connected to a wall or is ceiling mounted, resulting in a high level of comfort, low noise and cost effective installation.


  • Everything is enclosed in your apartment
  • Fully Internal – no outside access needed
  • Units are easily concealed
  • We Offer a Range of Internal Condensers, Including an Advanced Single Box Multi-Split Condenser For Cooling up to Three Rooms
  • Different room unit options
  • i-FEEL closer-to-you temperature control as standard on all DC inverter systems

From the first consultation visit, the communication in the build up to installation, and the installation itself the whole team were fantastic. Great neat job of the install, couldn't be happier!

The service provided was great from the very first inspection to the actual installation. They were clear on what to expect in terms of costs and timings. On the installation date, the installers showed up on time and were extremely careful and tidy when working. They basically left the place cleaner than before! Will definitely recommend.

Cool You Uk is an excellent company for providing superb air conditioning solutions for apartment living. I had installed three units a couple of years ago and all have been a great success with low maintenance. The installation team were fantastic and all the work was done within a day and a half. My only reason for not awarding the company 5 stars is because the cost to supply and fit was quite expensive. That said I don’t regret the decision to have the air conditioning and I would highly recommend this company.

Professional and efficient every step of the way. Very pleased with the installation and cannot believe I was actually able to get built in AC units in London without the need of a full construction job. The team came in and finished the job in half a day and cleaned up afterwards.

Excellent sales, installation and after-service experience - everyone I have spoken to has been super helpful and nice (starting with Savva). Very pleased with the end product too which is a life-saver in the summer times (hot, south-facing flat in London).

Second annual service and all very straightforward and easy. It has been very reassuring as buying a hybrid system that requires no external driver can feel like a leap of faith sometimes as it is a bespoke/niche product. Couldn’t be happier with our outcome and our two annual services have gone very smoothly with excellent customer service both in the back office as well as on site customer service. Without it during the summer of 2020 and a lockdown we would have melted.
