I always use an off cut of Marmox on top to prevent denting 

The simplest of tiling tools! It's only when someone says something like this you think 'oh yeah....why didn't I think of that'

I'l get both an alarm and multimeter ordered....both handy things to have.

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.

Just nobody stocks marmox by me but I used marmox a few times and I do think its a better product.

As bathrooms are considered "special areas" under part p of the building regs and you are not a "competent person" under the regulatory guidance you should not technically be installing fixed wiring systems without the involvement of either building control or a "competent person" who can certify the work under the regulations. If this doesn't happen it is technically an unlawful installation. In itself this is not an issue unless there is a problem with the floor e.g. A fire at which point you could find yourself in some strife.

This is always a concern of mine when hearing about underfloor heating systems in kitchens and bathrooms.

How do most tilers deal with the issues created by part p

Final connection made by certified electrician

I was planning on laying the boards and UFH mats, but have an electrician connect it to the mains, in order that any warranties are validated. I'm assuming a qualified electrician comes under 'competent person' or 'registered third party' as mentioned in part p?

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...

Some warm up kits come with the alarm.......you only need the one in ya toolbox.

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!!!

Yes, Warmup kits from Topps often come with a "watchdog" but I think they have stopped this now as have started selling the trade kits instead. My watchdog has just died
