To meet part p in kitchens and bathrooms the electrician has to be a member of a competent persons scheme e.g. Niceic registered. Provided he is registered he can self certify the work. Problem as I see it is that as he has not installed the cables he will only certify the connection so the cable installation itself is not certified...

My sparky always sees my stages of work in photos or in person, sees the resistance readings I record and certifies every installation no problems. He knows less about installation (laying) of electric UFH then I do!!!

Ugh. Dusty no more ply, hardy backer.
converted to insulation boards a while back, easier to cut and lay. Can be got for same price as cement board.
recent job customer supplied Marmox boards, they were good but I have used PCS insulation boards from tile town and they were much harder and heavier . So a vote from me for PCS.
i use them on solid or timber floors and instead of plasterboard in shower areas.

Yes, Hardi will indeed be fine. Out of interest what would be your reasons for choosing Hardi over Marmox? Always interesting to hear differing opinions on this. I'm a Marmox man through and through and used to fix Hardi all the time.
Unless I've missed a reply to this, the main reason I would use marmot or similar over hardie is purely because marmot will help the heat to just come up through tile whereas hardie let's heat through it which wastes money and heat response time.
they both do the job though but other big disadvantage of hardie against marmot is that it more expensive than trimline contractor board I use and takes far more time to fix which adds more cost

Trimline is a supplier of tiling tools and accesories.they make dukkaboard and also the contractor board.
both are cement faced front and back as marmot,wedi or similar.
i get best price by pallet from trimline although marmot is quite good value.i went off marmot few years back when the started supplying bowed boards. These were made in Egypt and left too long in sun I heard but they may well have sorted that now

Good shout there Alan. I'll keep that in mind for any future installations.

As as it turns out, customer has decided not to go with UFH. Turns out the brother is a plumber and is going to put a heated towel rail in instead.

Just bumping some threads in the underfloor heating forum. You can now find and search for both electric underfloor heating and water underfloor heating threads. By the way, if you feel some of the threads you want to be seen at the top of the forum need to be bumped back, for the next month or so from now, feel free to do that. Although it's not usually something we allow, whilst we're going through this process of changing over forum software, we see the need for this to happen.
