Average Labour Cost/Price to Fit/Install Bathroom Underfloor Heating


These prices are based on an electrician’s rate of £200 per day and a labourer if required
at £100 per day. They include, the cost of buying and collecting any materials, dumping any waste if necessary and any
incidental materials they will need.

(The minimum price will usually be for a half day)

Job 1
Remove the carpet, fit under carpet UF matting, combined roomstat & timer and connect to the main switch board.
This will take one man a day and a half …£300: materials will cost £450

Job 2
As above, but fit a cable system in an irregular shaped “normal sized” bathroom. This will take 2 man days, but the cable is cheaper so the price is about the same.

Then you will need special underlay but the old carpet can go back down.

A Price Guide and Information Sheet on Building/Fitting Bathroom Underfloor Heating

Remarkably, it’s possible to install UF heating an existing bathroom if the floor is nice and flat without removing anything other than the carpet and underlay. It has to be electric heating though, if you want a wet system run from your central heating, everything has to come out, and the floor taken up. Then you will want a new bathroom and tiling and decorating……….

I suggest you have a look at our main article on
Underfloor Heating.

If bath, basin and toilet are currently positioned to leave a free rectangular floor space, then you will probably be able to have under carpet matting laid down. If the floor area is irregular then cables can be laid to suite the space but this is more labour intensive.

There are different mats for different flooring materials, those designed to go under tiles aren’t suitable for carpets.

We are only going to price for an
under carpet electric system. If you want a tiled floor, everything has to come out (bath, toilet, basin) the floor needs to come up and interlocking boards or marine ply fixed down because tiles can’t be laid onto floorboards. Then you will probably want a new suite….You see, we are now way beyond just underfloor heating.

If you want a floating wooden floor laid, you don’t fit it
around things, so the toilet and pedestal need to come out, then these plus the basin need to be repositioned once the wooden floor is down. What about the disturbed tiling and the little “mind the step” sign you need to screw to the door. We’ve transcended just heating again hav’n’t we?
