Common questions
Electric is cheaper to install, usually £50 to £90 per square metre, and suits a single room like a bathroom. A wet system costs more to fit, around £90 to £150 per square metre, but is cheaper to run across a whole floor.
An electric system for a typical bathroom of 4 to 6 square metres usually costs £400 to £800 fitted. A kitchen or open-plan room on a wet system costs more.
It works well under tile, stone, engineered wood and many vinyls. Thick solid timber and deep carpet insulate too much and reduce the heat output, so check the floor finish first.
