Design
Heat loss, floor build-up and pipe spacing worked out room by room.
Heating · Underfloor
Warm floors, clear walls.
Wet underfloor heating runs warm water through pipes beneath the floor, so the whole room heats gently and evenly with no radiators in the way. It suits extensions, kitchen-diners, bathrooms and any renovation where the floor is coming up anyway, and it works well with boilers and heat pumps.

What’s included
The work, done properly.
- Room-by-room heat loss and pipe layout design
- Systems for screed, low-profile overlay and suspended timber floors
- Manifold, mixing valve and pump installation
- Zoned room thermostats and smart controls
- Connection to an existing boiler or a heat pump
- Fault finding on existing systems: cold zones, actuators and manifold leaks
Signs you need this
- You are building an extension or knocking through to a kitchen-diner
- Radiators are in the way of the layout you want
- Tiled or stone floors that are cold underfoot
- An existing system with zones that never warm up
Underfloor heating works at lower water temperatures than radiators, which is why it pairs so well with a heat pump, and with a condensing boiler that runs more efficiently when the water coming back to it is cooler. The trade-off is response time: a screed floor takes hours to warm up, so it works best on a steady setting rather than switched on and off like radiators.
The floor build-up decides a lot. A new extension can take insulation and screed with the pipes inside it; an existing room with little height to spare may need a low-profile overlay; a Victorian suspended timber floor usually takes pipes between the joists with spreader plates. The insulation underneath matters as much as the pipe, otherwise you are paying to heat the ground.
How it works
Coordinate
We plan with your builder so insulation, pipes and screed happen in the right order.
Lay and test
Pipes are laid and kept under pressure while the floor goes down over them.
Commission
Flow rates balanced, controls set and a new screed warmed up gradually.

Questions
Underfloor heating, answered.
Can underfloor heating go into an existing room?
Often, yes. Low-profile overlay systems add only a little floor height, and timber floors can take pipes between the joists. We check door thresholds and the floor finish first.
Wet or electric?
For whole rooms and extensions, a wet system running from a boiler or heat pump is usually cheaper to run. Electric mats can make sense in a small bathroom. We will tell you which suits the room.
Can I put wood or carpet over it?
Yes, with care. Tile and stone pass heat best. Engineered wood and thinner carpet on a suitable underlay work well; thick carpet and underlay hold heat back. We factor the finish into the design.
