Living in a city like London or a protected area in the South East presents unique challenges for home comfort. Strict regulations from building management, residents’ associations, or local councils often prohibit the installation of conventional air conditioning systems with their bulky, noisy outdoor units.
This is precisely the problem the Powrmatic Vision 2.3kW was designed to solve. As a ‘monobloc’ or condenserless unit, all the working components are housed within a single, slimline indoor appliance. It requires no external box, connecting to the outside through just two discreet 162mm grilles.
For our clients in:
…the Vision 2.3kW offers a pathway to powerful air conditioning that is not only effective but also compliant and visually unobtrusive. As dedicated specialists, we have successfully installed these systems in some of London’s most challenging properties, always without an outside box.

Beneath its elegant exterior, the Vision 2.3kW is packed with cutting-edge technology designed for performance, efficiency, and quiet operation. It represents a significant step forward in home climate control.
At just 810mm wide and with a depth of only 205mm, the Vision 2.3kW is one of the most compact and slender all-in-one units on the market. This minimalist design allows it to blend seamlessly into any interior decor. Its versatility means it can be mounted high on the wall like a traditional AC unit or low on the floor like a radiator, offering flexibility to suit your room's layout and your aesthetic preferences.
The Vision 2.3kW is a future-proof investment in your home's comfort and the planet's health. It utilises R290 propane gas, a natural refrigerant with a Global Warming Potential (GWP) of just 3. This is a dramatic improvement over older refrigerants (like R410a with a GWP of 2,088), making it fully compliant with the latest F-Gas regulations. By choosing the Vision 2.3kW, you're opting for a solution that is both environmentally responsible and highly efficient.
Air conditioning should be felt, not heard. The Powrmatic Vision operates at a near-silent 27 decibels on its lowest setting – quieter than a whisper in a library. This is achieved through precision engineering and high-quality components. Our expert installation process further ensures minimal noise by isolating the unit from the wall structure, preventing vibration transfer. It’s the perfect choice for bedrooms, home offices, and living spaces where peace and quiet are paramount.
Navigating the rules surrounding alterations to heritage properties can be daunting. At Innovative Air, this is our specialism. While traditional air conditioning is almost universally rejected for listed buildings due to the impact of the external condenser and pipework, the condenserless approach opens up new possibilities.
The key lies in the minimal exterior impact. The Vision 2.3kW only requires two small 162mm holes, which are finished with discreet, paintable external grilles. This approach is far more sympathetic to the building’s fabric.
Crucially, while you likely won’t need full Planning Permission, you will almost certainly require Listed Building Consent.
We have extensive experience working with conservation officers across London and the South East. We can provide the necessary technical specifications and drawings for the unit to support your application, helping to streamline the consent process. Our track record of successful installations in Grade II listed properties speaks to our expertise in balancing modern comfort with heritage preservation.
The Powrmatic Vision 2.3kW doesn’t just look good; it delivers exceptional performance. As an inverter-driven unit, it intelligently modulates its power to maintain a consistent temperature, saving energy and reducing running costs.

Because the Vision 2.3kW is also a highly efficient heat pump, its installation qualifies for 0% VAT under current government incentives for energy-saving materials. This can represent a significant saving on the total cost of your project. As your direct supplier-installer, we handle all the paperwork to ensure you benefit from this scheme.
When you choose Innovative Air, you are choosing a seamless, all-inclusive service. We don’t use subcontractors. Our own in-house, qualified F-Gas engineers and building experts handle every single aspect of the job.
We respect your time and your home. Our highly efficient workflow means we can typically complete a standard installation of a single Powrmatic Vision unit within just one working day.
Our promise is to leave your home as clean as we found it, if not cleaner. "Making good" is not an afterthought for us; it's part of our craft. This includes:
Every Powrmatic Vision 2.3kW we install comes with Wi-Fi control as standard.
We’ll install the app on your phone and show you how to use it. You can control the temperature, set schedules, and manage modes from anywhere in the world – perfect for pre-cooling your home on your commute back from the office.
The unit itself is legal. However, any alteration to a listed building almost always requires Listed Building Consent from your local council's conservation officer. Because the Vision 2.3kW is so non-invasive (no external box, just two small grilles), consent is far more likely to be granted compared to a traditional split AC system. We can provide technical documentation to support your application.
For most properties, including non-listed buildings in conservation areas, these small holes fall under 'permitted development' and do not require planning permission. The rules can be complex, but for the vast majority of our installations, planning permission is not a factor. We will advise you based on your specific property during our free survey.
For a single unit, we guarantee completion within one working day. Our teams are punctual, efficient, and work to a proven process that minimises disruption to your home.
It's recommended to service your AC at least once every 6 months to ensure optimal performance, better energy efficiency, and a longer lifespan.
Absolutely not. Our engineers use industry-leading dust suppression and extraction equipment during the core drilling phase. We use extensive dust sheeting and floor protection, and we conduct a full, professional clean-up of the work area before we leave.
Yes, providing the basement has at least one wall that is external (i.e., it faces the outside, even if below ground level in a lightwell). The unit needs to be able to draw in and expel air through its two vents, so it cannot be installed on a purely internal partition wall. We can assess the viability during a video survey.
Posted on Adam SingerTrustindex verifies that the original source of the review is Google. Danny installed AC units in my flat in the bedrooms and the living room. Very happy with the service and the installations. There was quite a lot of drilling to get through concrete walls and he left the flat very clean.Posted on gary parravaniTrustindex verifies that the original source of the review is Google.

Thank you very much to Dan and Tony for all your hard work on Saturday. My wife was very impressed with how clean and tidy you both were, so thank you.

His expertise was evident throughout the process, and he took great care to ensure that the unit was not only functional but also aesthetically pleasing. The AC operates efficiently and is impressively quiet, making it possible to comfortably sleep in the same room while it's running.Posted on Steve NashTrustindex verifies that the original source of the review is Google. With the heatwaves in summer our bedroom was unbearably hot at night, so my wife and I looked around for a solution. Our house is in a conservation area so we wanted to avoid having a big air-conditioning box on the outside. We came across CoolSleep where the unit is on the inside. We got a quote, which was less than we expected, and Dan and his assistant came to install it. We are very impressed with how neat and quiet the unit is, which can either cool our bedroom, or provide heat if needed. The controls are simple to use. Dan did an excellent job, he gave us various options re exact location, finish, etc., and cleared up very well. We certainly recommend CoolSleep.
