Electric underfloor heating

Is electric underfloor heating right for your home? Read on to find out how it works and how much it costs to install.

Underfloor heating can help keep floors and rooms warm and offer a space-saving alternative to radiators. It can sit beneath pretty much any type of floor, including stone, tile, wood and carpet.

There are two main types of underfloor heating: electric underfloor heating, which is also known as a dry system, and water underfloor heating, also called a wet system. On this page we look at how an electric system works (you can find out more about water underfloor heating here).

How electric underfloor heating works

In an electric underfloor heating system, a series of electric wires or electric heating sheets are installed beneath or within your flooring. These are used to heat an area or a room, such as a cold, tiled bathroom floor.

They're usually placed on top of a layer of screed (to ensure the surface is completely flat) and a layer of floor insulation (to ensure the heat travels upwards rather than down). 

There's an electric underfloor heating system for nearly every flooring type. The electric system you install will depend on the size of the room and how well insulated it is, what the flooring below it is like, whether it is insulated and the type of flooring you'll have on top. Options include loose-fit wiring flexible enough to fit into small or awkward spaces, electric cable systems, or heating mats you roll out to cover larger areas.

Our guide to underfloor heating pros and cons lays out everything you need to know to make the right decision, including expert buying tips. 

Installing electric underfloor heating

Most people choose to employ a professional company or trader to install underfloor heating. Professionals are also best placed to recommend what system to install and how to prepare the floor.

If you are a confident DIYer, you could feasibly install the electric heating sheets or cables yourself - but you'll need a qualified electrician to connect your system to your electric mains supply and fit a sensor that connects to the thermostat. The sensor allows you to control the temperature and pre-set the system to turn on or off.

Electric underfloor heating costs

Prices for roll-out underfloor heating mats start from around £180 for a kit with 10 square metres. You'll also need to factor in the cost of insulation board, screed and heating controls, as well as an electrician's call out and labour charges. 

We've researched the cost of installing electric underfloor heating, and asked installers across the UK to tell us what can affect the price. You can find out more by going to underfloor heating cost and installation.

Because electric systems are generally quite thin and simple to fit, they can be easier and less hassle to install in an existing room than a wet heating system, which requires some space for pipework and could involve the floor being raised.

Electric underfloor heating is cheaper to install than a wet system (and you can even do it yourself) but it's more expensive to run. For that reason, many of the installers we spoke to don't recommend this form of underfloor heating for large areas.
