Underfloor heating costs

Underfloor heating can be an efficient way to heat an area in your home. It distributes the heat across a room, unlike radiators, which focus the heat in one place.

There are two types of underfloor heating: water and electric. Water-filled systems are generally cheaper to run than electric ones, as they can be run at lower temperatures than radiators. Running costs also vary depending on how much of your home has underfloor heating and how often you use it.

In our survey, of those people who have underfloor heating:

  • 69% have an electric system
  • 26% have a water system
  • 5% have both types.

If you install an underfloor heating system, it will have a separate thermostat to the rest of your home. This means you can set specific temperatures for the room it’s installed in, which can help reduce your bills. But having underfloor heating in a number of rooms with separate thermostats is costly to install.

Underfloor heating: what to think about

There are some key things it’s worth keeping in mind when considering whether to get underfloor heating. 

First, are you getting your underfloor heating fitted in a new room, such as an extension, or retrofitting it somewhere that already has flooring? Putting underfloor heating into a new room is a lot simpler and less expensive, as you won’t have to take up old flooring.

The most popular place to have underfloor heating is in a bathroom – more than half (51%) of our underfloor heating owners have it installed there. The next most popular room is the kitchen (38%). 

Next, consider the type of system and where it will be installed. Generally speaking, water systems are better suited to bigger rooms. 

Electric heating systems are a lot cheaper to buy and you can install one yourself, although you will need an electrician to connect it up. Water systems are more complex, so you’ll it to be installed by a professional plumber or heating engineer.
