There are loads of options with under floor heating.
You ask if it is expensive, define expensive?
You normally need a programmer/thermostat and either heating matt or heating cable (different brands use different methods).
The types I have used can go on top of your floor boards (or ply), then you tile on top of the heat mat. You need to specify to the supplier that is is for going on top of a wooden floor because there is a different type for going on top of concrete/screed floors.
Normally a bathroom fitter will install it but you need to make sure they are Part P registered ("competent" to do the electrics). Other option would be for the bathroom fitter/plumber/tiler to lay the heating mat and a Part P registered electrician to connect it up.

If you do a quick Google for under floor heating you will get an idea of how much it costs. Different brands = different prices. I have used Devi, which is not cheap but it is good.

Really makes a difference with under floor heating and I am sure you will be very happy if you do fit it!

Yes, would have to be RCD protected though, and meant to leave details of the installation by the consumer unit
