It's all we do - Cool You are the true specialists!


Are you looking for air conditioning without an external unit for your Grade II listed property? If you are, Cool You UK can help and we 100% guarantee we will have an air conditioning solution for you.

For cooling and heat extraction, we utilise the mains water and drainage system of your property. The condenser is then connected to wall or ceiling mounted air conditioning units resulting in a high level of comfort, low noise and cost-effective installation.

You may have found air conditioning your listed property somewhat challenging. Many of our previous customers have come to us after being told they cannot have air conditioning because of the protected status of their building. We are here to solve that challenge with our range of air conditioning solutions with no external unit.
Our air conditioning solutions for listed buildings do not have outside condenser boxes. Everything is contained within the internal structure of the property. Taking into account the constraints imposed by planning departments, conservation officers and freeholders of listed buildings and properties in conservation areas, our DC inverter completely air conditioning systems are the only solution.

Apartment Air Conditioning Solutions for Listed BuildingsCool You UK have considerable experience in meeting the specific challenges of installing air conditioning in these difficult environments and we are here to provide you with a tailor-made solution to air condition your listed property.

Water-cooled internal condenser air conditioning is the perfect solution for those who are restricted in what they can do when retro-fitting air conditioning. If you live in a listed building (or within a conservation area) you may be unable to gain planning permission to make holes in your exterior walls to accommodate a conventional condenser unit. Water-cooled internal condenser air conditioning solves this problem.

With a conventional split air conditioning system, the condensing unit has to be installed outside. Our entire system is fitted within the internal rooms of your property or apartment.


All of the air conditioning systems we supply and install at Cool You UK are Wi-Fi enabled and can be controlled wherever you are using the Clima 24H app.

Available for iOS and Android devices, the app allows you to control the operation of your air conditioning through your Wi-Fi network.

My first experience of Cool You was a good one. Tommy, their youthful engineer (I'm 73) took the time to explain their system that I had taken over in my new apartment so that I could use my three units safely and efficiently. Further back-up came from head office who sent my operational instructions that had not been left by the previous owners. I feel confident that any difficulties that I might encounter in the future will be dealt with kindly and efficiently.

Really happy with the thorough on site assessment of our flat, which compared to other visits by another team, was streets ahead in being able to answer my queries and give me the reassurance we needed to proceed. The installation was on time and effortless, and we love our new air con unit! We can barely hear the condenser during it's operation, and we can chill a previously inhospitable sweat-box of a room in the summer in under a couple of minutes.

Excellent service and equipment I'm writing this on behalf of my parents. At the beginning of June we had air conditioning installed in the lounge by Ultra Cooling. Paul Kibble and did the job. It was a very technical assembly and they were obviously experienced experts. Their specialist equipment ensured there was not a speck of dust or cleaning afterwards. The system works well and from our experience we would definitely recommend them and use them again 10/10

A Cool Summer I have recently had a Cool You aircon system installed in my London apartment. My living room has floor to ceiling glazing with a southerly aspect and in the Summer it used to become unbearably hot and humid. Not anymore! This water-cooled system now keeps it at the temperature I choose and my apartment living has been transformed. I would highly recommend this aircon system. The initial cost may seem high but be assured the product is first rate and Cool You are highly professional in the service they provide with their speedy and tidy installation procedures, their subsequent aftercare, and the efficient and courteous way they deal with their clients.

A great product and team - pre and post sales Excellent product and customer care. Continuous support and responsive team who don’t drop you the second they’ve made the sale, but genuinely care about your considerations and any subsequent servicing. Very understanding and accommodating over the Covid period.

Easy, friendly, no extras, no fuss. The site visit was timely, sensible, quote followed quickly, dates given were all met. The installation was just over a half day (2 rooms, one condenser). No mess left. Product works well (for the last 3 days since installation). All easy, friendly, no extras, no fuss.

Expensive but works flawlessly The solution is expensive but you get what you pay for - and what you get is a very efficient air conditioning system, installed professionally and to a high standard. My property has 2 bedrooms located in the loft (one of which is south facing) which can get uncomfortably hot in the summer. After the last year's summer and having to deal with a noisy and rather fiddly (especially with Velux windows involved) portable aircon I decided to bite the bullet and get Cool You to install a water cooled solution in my property (external compressors were not allowed by the freeholder). I have to say that it's more than adequate to cool (and maintain) the entire upstairs to a pleasant 22C in a matter of minutes which is a huge quality of life improvement. The installation was also very efficient and done professionally - the installers arrived punctually at 8am and were done by lunchtime - I honestly did not expect such efficiency given the rather unusual layout of my property and what I though could have been challenges with finding the right spot to install the condenser. They installed the it neatly in the loft (I initially thought there might be issues with water and power supply but I shouldn't have worried as they somehow did their magic and got water, power and waste sorted) and two wall-mounted units in the bedrooms. There was indeed no mess and minimal disruption, which I was initially rather sceptical about despite the claims on their website. So far the system does the job although I can't comment on the running costs as it's only been a few weeks since the installation. Overall a good experience, job done to a very high standard and delivering on their promise. Yes, it's not cheap but I wouldn't think twice about spending the money given how much more liveable my property now is in the current hot weather.

Great a/c solution in a flat Really neat a/c system with no external fittings needed so it was the ideal solution for our flat and I couldn’t be happier. Prompt service and helpful fitters.
