Underfloor heating installation for London extensions and refits
Our underfloor heating installation in London runs off your boiler, not off electricity. Pipe loops sit in or under the floor, a manifold feeds them, and controls give each room its own temperature. It works best in an extension or a full refurbishment. Fitting it room by room into an existing home is a harder sell, and we’ll be straight with you about which one you’re looking at.

What the job involves
- Water-fed underfloor heating for extensions and refits
- Manifolds fitted, flow rates set and loops balanced
- Screed systems, or low-profile boards when height is limited
- Thermostats, zone valves and wiring centres
- Hooked up to the boiler, cylinder or heat pump you already have
- Cold loops traced and repaired
A few things to check
A quick look might sort it without us. We’re happy to say so.
We fit water-fed systems, not electric mats
Electric mats are work for an electrician, and they rarely make sense outside a small bathroom. Everything we fit here is wet: warm water flowing through pipe loops from your heating system. Been quoted electric for a whole floor? Ask someone else about the running costs before you agree.
Floor height usually decides it
How much height have you got to play with? Traditional screed builds the floor up noticeably. Low-profile boards keep the rise small, but you pay more per square metre for them. In a London flat, where the door heights and floor level are already fixed, this one choice is often settled before any other.
It needs cooler water than radiators
Underfloor heating runs much cooler than radiators do. Adding it to a system designed for radiators means fitting a blending valve and decent controls. Skip that and you get a warm floor upstairs and a cold one downstairs, or a boiler that keeps firing on and off until it wears itself out.
Doing the whole house is rarely worth it
Pulling up every floor in a home you’re living in almost never pays for itself compared with better radiators and controls. It makes sense when the floors are coming up for other reasons.
Questions we get a lot
Does it work under wooden or engineered floors?
Engineered boards and most tiles are no problem. Solid wood expands and shrinks, so the board and the flow temperature need choosing carefully. Thick carpet and heavy underlay hold the heat back, but a thin underlay is normally fine.
Can my boiler run underfloor heating?
In most cases, with the right controls in place. The questions are whether your boiler can turn itself down low enough, and whether the system can be zoned properly. We check both before we give you a quote, not afterwards.
How quickly does it heat up?
Think hours, not minutes. A screed floor is a big, slow-warming mass. So you set it on a schedule and leave it be, rather than switching it on and off like a radiator.
A loop has stopped heating. Can you sort it?
Most of the time, yes. It’s usually trapped air, a stuck actuator or a blocked loop, not a burst pipe. We test each loop at the manifold, so your floor stays where it is.
