ONE UNIT, FOUR JOBS

What It Does

No Outdoor Unit monoblock unit

Air Conditioning →

Cool rooms all summer in flats and buildings that have been refused a condenser.

No Outdoor Unit monoblock unit

Heating →

It is a heat pump, so it moves heat rather than making it. Around three units of heat for every unit of electricity, far cheaper to run than electric heaters.

Condensation and Damp →

Dry mode takes moisture out of the air, so windows stop running with water.

🌱 GREENER HEATING

Heat one room, not the whole house.

Working from home, or just want the lounge warm? Firing up the boiler heats every radiator in every room. No Outdoor Unit heats only the room you are in, with a heat pump that turns 1 unit of electricity into around 3 units of heat.

THE UNIT

One Box, Every Part Inside It

A split system puts half the machine on your outside wall. Ours keeps everything in one body, and only air leaves the room, through two neat grilles.

GOOD TO KNOW

Frequently Asked Questions

How much does it cost?

Our introductory price is £1,595 supply and fit for one room, with 0% VAT. Every wall is different, so we confirm a fixed written price after a free survey.

How loud is it?

Louder than a split system, because the compressor sits in the room. On low it is around the level of a quiet fridge, and on full it is clearly audible.

Do I need planning permission?

Very rarely, as nothing projects from the building. Check your lease with your freeholder or managing agent, and listed building consent may apply. We talk it through at the survey.

Which areas do you cover?

North London, North West London, Central London and the surrounding counties, including Hertfordshire and Middlesex.

How quickly can you fit it?

Most installs take one day on site, and we confirm a date with your written price.
