Find out some top tips on what to think about when buying and installing underfloor heating systems.

How much you pay for underfloor heating varies dramatically, depending on what type of underfloor heating you get, whether it will be installed in a new room or retrofitted to an existing room, and what your floor structure is like.

You'll need to think about:

  • whether you want an electric or water system
  • the number and type of rooms you want it installed in
  • each room's size
  • if you want to get rid of the radiators in that room
  • whether you will install it yourself.

These are just some of the factors that can affect the cost of underfloor heating. So you don't end up paying more than you should for underfloor heating, or make a choice that you later regret, we've done the hard work for you.
