It is fitted as part of a bathroom, en-suite or kitchen refurbishment, most often using Thermosphere systems. It suits any tiled room where cold floors are a known problem: bathrooms and en-suites in older properties around Sevenoaks and Tunbridge Wells, large porcelain kitchen floors in Bromley and Beckenham, and new-build en-suites. Plan it before tiling starts, since the mat, insulation board and adhesive all add floor height. It has to be right first time because the heating element is buried under the tiling. There is no way to inspect or repair it without lifting the floor, so damage caused during installation only shows when the system is switched on. ### What you get - Thermosphere systems fitted regularly - Continuity tested before and after tiling - Mat fully encapsulated in adhesive - Sensor placement planned with the layout - 1-year workmanship guaranteeRequest an Estimate What it costs to leave it ## Why mats fail, and what it costs to fix once tiled over The commonest cause of failure is physical damage during tiling: a trowel edge cutting a cable, or a mat pierced by a screw. Locating the fault then needs specialist testing, and fixing it means lifting tiles. The second is burying the mat without testing continuity before and after tiling. An already faulty mat is only discovered when the heating goes on and part of the floor stays cold, with tiles already down. Either way the heating simply does not work, and the repair is disruptive next to the simple step of testing at each stage. Sensor placement is the other overlooked detail: a sensor under a fixed unit gives a false reading. ### Mistakes that cause it - Damaging heating cable or mat with a trowel or screw during tiling - Not testing continuity before, during and after tiling - Placing the floor sensor under an area that will be covered by a fixed unit - Not accounting for the added floor height against door thresholds - Using the wrong adhesive thickness, leaving the mat under-encapsulated - Running the system too soon before adhesive has fully cured How the work runs ## A process you can follow Step 1 ### Site visit and system selection James assesses the room, existing floor build-up and heating requirement, and discusses suitable electric systems including Thermosphere, coordinating with an electrician from his trusted network for the final connection. Step 2 ### Insulation board and layout Insulation board is laid where needed to direct heat upward rather than into the subfloor, and the heating mat layout is planned around fixed units, thermostat position and sensor placement. Step 3 ### Mat installation and continuity testing The mat or cable is fitted, and continuity is tested before any adhesive or tile goes near it, confirming the system works before it becomes inaccessible. Step 4 ### Encapsulation and further testing The mat is fully encapsulated in adhesive with careful trowel technique to avoid damage, and continuity is tested again once covered, before tiling proceeds. Step 5 ### Tiling and final commissioning Tiles are laid over the cured adhesive bed, a final continuity test is carried out, and the electrician connects the thermostat so the system is confirmed working before handover. ## What you actually get out of it ### Tested at every stage, not just at the end Continuity is checked before, during and after tiling, so faults are caught while they are still fixable rather than after the floor is finished. ### Full encapsulation protects the mat long-term Correct adhesive coverage means the heating element is fully protected within the floor build-up, not left exposed at the edges. ### Warmer floors without retiling later Fitted as part of a tiling job, underfloor heating adds comfort without a separate, disruptive phase of work. ### Coordinated electrical connection James works with a trusted electrician to connect and commission the thermostat, so the tiling and electrical work are sequenced correctly. ### Fixed pricing as part of the tiling job Underfloor heating installation is quoted alongside the tiling work, with a fixed price and staged payments. ### 1-year workmanship guarantee The tiling and installation work is covered for a year against workmanship faults. ## Electric Underfloor Heating Installation in detail ### Systems: mats, loose cable and Thermosphere Mat systems, where the heating cable is pre-spaced and fixed to a mesh, are the most common choice for regular-shaped rooms because they are quick to lay evenly. Loose cable systems offer more flexibility around awkward room shapes, fixtures and irregular floor plans, at the cost of more careful spacing during installation. Thermosphere is one of the systems James fits regularly, and is a routine part of bathroom and en-suite refurbishments across Kent. Both mat and cable systems rely on the same core principles: correct spacing to avoid hot spots or cold spots, insulation board beneath to direct heat into the room rather than the subfloor, and testing at every stage before it disappears under tile.
