Your flat is a heat trap. Let's fix it.

Whether you're in a Victorian conversion, a new build flat, a top-floor apartment, or a leasehold studio — your home traps heat. Modern insulation, sealed windows, and south-facing rooms all make it worse every summer. The fans and portable units don't fix it.

There is a real solution — invisible air conditioning, integrated into your apartment. Concealed, colour-matched, fully turnkey.

Why we're different

Invisible air conditioning.
That's the whole point.

Most installers will happily bolt a bulky outdoor unit anywhere it fits and box pipework in plastic trunking. We won't. Everything we do is about integrating air conditioning into your apartment so seamlessly it looks like it was always there — and your property comes back to you exactly as it was, only cooler. And there's no one-size-fits-all: we carry multiple solutions and design the right one around your specific property.

💧

No outdoor unit at all

Our patented HomeKube™ water-based system needs no outdoor condenser — nothing bolted to the building, nothing to deface the façade.

🫥

Concealed & hidden away

InvisiGrille™ conceals indoor units behind bespoke flush grilles — and where an outdoor unit is needed, we hide it away from sight, never in ridiculous places.

🎨

Colour-matched to your interior

Units finished in 250+ colours to match your walls and interior — not a white plastic box dominating the room.

🤍

Seamless, turnkey finish

No plastic trunking — pipework is plastered in and made good. Electrics, redecoration, everything handled by us, with minimal disruption. Your apartment comes back to its original state. Just cooler.

The most common things we hear

"I didn't think I could have air conditioning in my flat."

Most apartment owners assume it's impossible. In nearly every case, it isn't. Here's what we hear — and the truth.

My building is Victorian — I can't drill through anything
✓ Yes you can.
We've installed in hundreds of Victorian conversions across London. External unit placement and discreet pipework routing is what we specialise in. Your building has been through far more than a few carefully placed holes.
My new build doesn't have space for an outdoor unit
✓ We have a patented solution for that.
New build apartments often have no balcony or communal restrictions on outdoor units. We have multiple solutions designed for exactly this — from our patented HomeKube™ water-based system with no external unit at all, to fully concealed and hidden outdoor options. We match the solution to your specific property.
I'm on the top floor — it'll be too hot to fix
✓ Top-floor flats are our bread and butter.
The top floor is the most common flat we work in — roof heat, south-facing windows, no airflow. We know every challenge it brings and size the system to handle it properly.
My management company will never allow it
✓ Most do, with the right approach.
We work with leaseholders every week on this. We know exactly how to present the works — specifications, methods, materials — in a way that satisfies management companies and freeholders. We'll support you throughout.
The difference it makes

Life before. Life after.

It sounds simple. Until you've lived it, you don't realise how much of your summer you've been giving away.

Before
  • Wake up at 3am because you can't sleep
  • Blinds down by 10am to stop the flat overheating
  • Fan running all night — noise, warmth, no relief
  • Work-from-home impossible above 28°C
  • Portable unit: noisy, ugly, needs emptying constantly
  • Dreading the summer forecast
  • Guests uncomfortable — apologising for your own flat
After
  • Sleep through summer nights at whatever temperature you choose
  • Blinds open — natural light, no heat trap
  • Silent running — you'll forget it's even on
  • Work-from-home in genuine comfort, all year
  • One slim wall unit — unobtrusive, even beautiful
  • Looking forward to the long evenings
  • A flat that feels like a home, whatever the weather
The last upgrade

Your apartment is finished.
Except for the air.

The new kitchen. The bathroom. The perfect paint, the flooring, the lighting. You've invested in every detail of your home — except the one you feel the moment you walk in. Air conditioning is the single upgrade a finished London apartment is still missing: everyday comfort, better sleep, and real added appeal when you come to sell. The Ideal Home Show calls it the number one investment a homeowner can make. We make it invisible.

Stuffy hot apartment before air conditioning
Sound familiar?

You've already tried everything. It doesn't work.

The fan that just moves warm air around. The portable unit that sounds like a diesel engine. The blackout blinds that keep the room bearable but make your flat dark by 10am. Every summer, back to square one.

Victorian conversions trap heat. New builds seal it in. Top-floor flats absorb it from the roof all day and release it all night. Every flat type has its own reason — same result.

None of it is a solution. It's all just coping. There is a real answer. It just needs to be installed properly.
