Bathroom tiling dot and dab

[Mark parry]

Hi I need some help I am having my bathroom tiled onto plaster board my tiler has put them on with dot and dab 45x90 tiles is this ok and also puting underfloor heating mat down with 45x90 tiles dot and dab my understanding it should be total coverage on floor tiles.
The pic is one of the tiles that was loose and he redone it today I queried dot and dab on the floor but he said it is because of the underfloor heating.
Any help appreciated

No, and if he’s doing this don’t let him do anything else except Let him collect his tools and go do one. Complete cowboy

Thought so I haven't been in while he was doing the tiling here are some photos of the back of the wall tiles their is a big gap between tile and wall.

If you have any spare tiles try holding one above your head. Then imagine the extra weight of the adhesive. Then imagine that falling on you while you're in the bath.
It all needs to be stripped and started again. Voids caused by air gaps around the ufh will cause it to fail as well.

At least they’ll be easy to remove. May even be able to save some tiles

It is all condemned. It has been fitted with no regard to British Standards. It is shoddy, dangerous and needs ripping out. Sorry 🙁

He’s not even a multi trader let along a tiler.
How can anyone think that’s acceptable!!!
That ufh would overheated immediately
