Coole & FrostCoole & Frost

Comfort

Built for sleep.

The case for cooling a London home is really the case for eight hours of deep, uninterrupted sleep — for you, and for the small people down the corridor.

The science, briefly

Bedrooms belong between 16° and 19°.

Sleep researchers broadly agree: core body temperature has to fall for deep sleep to arrive, and it can't when the room won't let it. London's brick terraces are superb at holding heat — wonderful in February, miserable in July, when upstairs rooms routinely sit above 28° at midnight.

A Coole & Frost system holds each bedroom at its own set point — 18° for you, 19° for the nursery — silently, all night. No fans, no open windows onto street noise, no wet flannels on foreheads.

Heatwaves are the new normal

London hit 40.2° in July 2022.

The ten warmest UK years on record have all come since 2003. Heatwave nights that used to arrive once a decade now arrive every summer — and homes designed for 1890 weren't designed for them.

  • Cooling sized for the record books, not just the averages — comfortable even on the outliers.
  • Filtered, circulated air with the windows shut: less pollen, less particulate, less traffic noise.
  • Stable humidity as well as temperature — the part fans can't do and everyone forgets.

For the whole household

Comfort is a family matter.

Babies sleep badly above 20°. Teenagers revising in loft rooms cook from June onwards. Grandparents feel heat harder than anyone. When we design your system, we design for the people in each room — not for an average of the house.

Sign-off from the household's chief comfort officers comes as standard. In whisper mode, our indoor units are quieter than a purr — and considerably easier to negotiate with than either of them.

The part nobody expects

In January, the same system heats.

Modern climate control is an air-to-air heat pump. Run in reverse, it delivers roughly three to four units of heat for every unit of electricity — among the cheapest ways to warm a room in Britain today. One discreet system; comfort in both directions, all year.

Room by room

Every room gets its own climate.
