29.4°
A heatwave night in London. Upstairs:
And rather less than you’d imagine.
Whole-home heating and cooling for London houses — slim wall units designed to be admired, and low floor units that sit where the radiator did. Fitted in days without building work, and for most homes without a planning application.
Why Coole & Frost
Cool bedrooms on the hottest night of the year. Gentle warmth in January. Rooms that simply feel right, whatever the weather is doing outside — from units designed to belong in them.
Coole & Frost fits slimline inverter heat pumps made for beautiful rooms — wall units flat and quiet enough for a period bedroom, placed high out of the eyeline, or low floor units exactly where the radiator used to live, dressed in a radiator-style cabinet if you wish. One quiet condenser serves the whole house, most installs need no planning application at all, and the work takes days, not weeks. Comfort for your family, style your home deserves, and paperwork done to the letter.
Bedrooms at 18° on the hottest night of the year — and gently warm in January.

More →The Coole & Frost unit
A heat pump in a slimline case that belongs on the wall of a period bedroom — flat fascia, soft corners, a quiet Coole & Frost badge. And for rooms that suit it better, a matching floor unit that sits where the radiator did. Both heat in January and cool in July.
The point of all this
London summers now regularly push bedrooms past 28° at midnight. A Coole & Frost system holds every bedroom at the temperature sleep scientists actually recommend — silently, all night, whatever the forecast says.
Every room held anywhere from 16° to 32° — your choice, room by room, all year.
Night setting. Quieter than a library reading room — soft enough for a nursery.
A typical whole-house installation — no ducts, no ceilings opened, made good as we leave.
F-Gas certified engineers on every job. No exceptions, no subcontracted surprises.
Period homes, first and foremost
Stucco crescents, Victorian bays, pastel conservation streets — these are the houses we design for every week.
One compact condenser at the rear, slim units placed room by room — and for most of these houses, no planning application at all. The house keeps its face. You get your summers back.
How it works
An hour at your home. We measure, listen, and look at how you actually live — then design around it.
Positions agreed room by room, condenser siting — and the MCS noise check that keeps you inside permitted development.
Brackets, slim trunking, tidy pipe runs — no ducting, no ceilings opened. Days, not weeks; then we make good.
Commissioning, a proper handover, and an annual service that keeps efficiency — and warranties — intact.
Where we work
A design visit takes an hour, costs nothing, and comes with a fixed quote — not an estimate.
