Everything your home needs for comfort

Stop juggling radiators, portable air-con and extractor fans. Custom Comfort does it all from a single, efficient system.

Heat

Even, draught-free warmth in every room — less than a 2°C difference floor-to-ceiling and wall-to-wall. Pairs perfectly with modern heat pumps.

Cool

The same system delivers gentle, whole-home cooling in summer. No bulky wall units, no noisy outdoor racket — just steady, comfortable air.

Ventilate

Built-in filtration and optional heat-recovery ventilation bring in fresh, clean air — removing up to 30% more humidity than a traditional system.

Why homeowners choose it

Comfort you feel. Technology you don't see.

Because the ducts are just 50–63mm, they hide inside walls, floors and ceilings — so you reclaim your walls and keep your interior exactly as you designed it.

Discreet by design

No radiators, no wall units. Just neat, unobtrusive outlets.

Whisper quiet

Sound-attenuating ducts isolate noise and vibration.

Cleaner air

Filtration removes dust, pollen and allergens.

Retrofit friendly

Slim ducts thread through existing homes with minimal mess.

Unit
How it works

Small ducts. High velocity. Even comfort.

A compact air handler gently pushes conditioned air through slim ducts. The air "aspirates" — mixing softly into each room instead of blasting in — so temperatures stay even and draught-free.

Compact air handler

A single modular unit — sited in a loft or cupboard — heats or cools the air, paired with a heat pump or boiler.

Slim, flexible ducts

50–63mm sound-insulated ducts route discreetly through the structure of your home.

Aspirating outlets

Small wall, floor or ceiling outlets gently mix air into the room for even, comfortable temperatures.

Fresh, filtered air

Filtration and optional MVHR keep the air clean and humidity balanced, all year round.
