Underfloor Heating Buying Guide
Everything you need to spec the right electric underfloor heating for the job.
Heating cables suit irregular room shapes and let you space runs to hit a target watt/m². Heating mats are pre-spaced on a mesh backing and roll out fast in square/rectangular rooms — the quickest install for tile bathrooms and kitchens. Heating foils are ultra-thin and designed for floating floors (laminate, engineered wood, click LVT) where you don't want to raise floor height. Foils are not suitable under tile.

Electric underfloor heating for a typical 4 m² bathroom starts around £120 for a heating mat and £60 for a thermostat. Larger open-plan areas of 15–25 m² typically cost £350–£700 for the heating system plus thermostat. Our systems are trade-priced up to 39% below RRP.
