Product Details

Underfloor heating can be installed beneath many types of floor finishes, including tiles, carpets and wood. With our in-screed heating kit, you receive easy-to-fit heavy duty cable, a manual dial thermostat and adhesive tape, along with spray and double-sided edge tape for a simple installation.

  • Designed to be installed in a screed mix, our heating cables are heavier duty than the type you would install beneath wood or tiled floors. At 5.5mm in diameter, they are suitable for fitting either beneath or within a screed floor.
  • Able to heat the large expanse of a mix base, output is sufficient for use as a primary heating source beneath flagstones and thick tiles.
  • Our kit contains your desired length of cable and a manual dial thermostat, with the option to upgrade at a small cost to a digital version. We also supply adhesive tape to secure the cables in position, double-sided edge tape and spray adhesive.
  • When it comes to ordering your in-screed heating kit, you will need to carefully calculate the length of cable required to ensure that you slightly under order, as our cable cannot be cut during installation. If you need any assistance in calculating the size of the kit you require for your installation, you can contact us for help. You can also purchase a standard kit for rooms sized up to 17.75m2. For areas larger than this, please contact us for pricing.
  • All of our electric heating solutions are guaranteed for life and, when you order from Underfloor Heating Direct, you can shop with confidence with our secure payments, comprehensive returns policy and free delivery (terms apply).

Please note : The brand of heating cable supplied may vary subject to stock levels

  • Fitting our in-screed heating cable is straightforward and can be undertaken by DIY enthusiasts or professionals.
  • If your concrete base is less than 100mm thick and insulated, you can lay the cabling straight on top of it. Using the adhesive tape to secure the cable with even spacing, and connected the power and temperature probe, you can lay screed directly over the cables (up to a depth of 65mm) and finish with your choice of flooring.
  • If your base is over 100mm or uninsulated, you must ensure that insulation is laid prior to fixing the cable in position. You can do this in one of two ways:

Option 1:

  • Put 10mm insulation board over the concrete base
  • Fit in-screed cable
  • Lay 65mm screed
  • Place floor covering

Option 2:

  • Put 50mm insulation in place
  • Lay 35mm screed mix
  • Fit in-screed cable
  • Lay further 30mm screed
  • Add floor covering


Rated at 17w per linear meter, the power output of our in-screed heating cable can be varied according to the spacing during installation, with an output range of between 160w/m² and 220w/m².

Our cable consists of a resistance heating wire with a primary insulation of Teflon surrounded by metal armour, and finally a second sheath of fluoropolymer. The construction of our cabling ensures that the installation is durable and will last a lifetime, guaranteed.

Flexible in design, the cable is easy to install and meets all of the test requirements of IEC 60335, as well as being CE and SEMKO certified.
