Somestimes the UFH makers will provide guidance.. See "specification 2 - Existing Timber Floors with Undertile Heating".

There are products like BAL Fastflex which you can use to tile directly to the floor boards providing they are screwed down and not just nailed and they are in good condition, but I don't think you are meant to lay heating cables directly on them due to the expansion of the timber etc.

Not only does the installer appear to have done any of these things, he also admits to you that his mix was too thin. Have you paid him / got any other leverage you can try and apply?

Are my options to rip it all up and start again (unsure if it will damage UFH), can not do myself so costly, put insulation under floor boards, cut my losses and play the waiting game and see what happens in the long run or anything anyone can think of. If it was you, what would you do? Thanks for your time.

A cheap easy solution..... Just regrout the odd cracked grout joint using an Epoxy grout, very flexible and can't crack, this will bond the tile edge to the tile edge... for life!
Then... should in the future (god forbid) the odd tile comes loose, lift it, clean it off and then restick it using BAL Fastflex, again, this stuff you could tile your curtains with if you wanted, very very flexible and sticks to anything. This is also suitable for use with UFH.
It isn't really a long-long-term plan but will certainly do the job for a while. Eventually you'll end up with lots of the floor flexing more than other areas due to the fastflex moving as much as the substrate wants to, and the less flexible adhesive trying to hold things still which will end up cracking more grout but that's after you've done big patches of fastlfex-ing.
Both epoxy grout (BAL Easypoxy) and rubber based flexible adhesive (BAL Fastflex) are available from www.toppstiles.co.uk
Hope this helps

I still feel gutted that that this problem has occurred but reassured that there is still honest and helpful people in this world.
One final thing. I have a partition wall to be built, walls + floor to tile, bathroom suite to install, where can I find a good craftsman who charges reasonable prices? I live in the North East of England, Near Newcastle.
Thanks again for all your help, greatly appreciated. Jacci
