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.
Underfloor Heating FAQs
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.
