Underfloor heating installation

Underfloor heating warms a room evenly from the floor up and frees the walls of radiators. It runs at lower water temperatures than radiators, so it can be more efficient, particularly in a new extension.

Timing matters

Underfloor heating is easiest to fit during building work, before screed or flooring goes down. Talk to us at the planning stage and we will work around your builder.
