Electric Underfloor Heating – Supply & Install

We have carefully chosen our Electric Underfloor Heating systems for their high quality, their affordability, but also for their ease of installation. German-engineered, our self-adhesive mat kits are particularly simple to install, even for those who are laying underfloor heating for the first time. However, sometimes, it's nice to have the responsibility taken from your shoulders and get the experts in to do it for you.
Our team of fully certified electrical installers have, combined, decades of experience in the underfloor heating industry, so you can rest assured that all the complicated legal obligations are fulfilled and that your 16 year manufacturer’s warranty is secure. Our installers will do all the hard work for you by laying out your insulation, as required, planning out the positioning of the mat and then installing it for you. They will even put down the self-levelling screed for bonded (stuck down) flooring so everything is ready for your installer to come along and lay your new floor.
