All of your advice is much appreciated. No worries there.

I'm paying what I would consider to be the right money to have the job done, so I expect it too be done correctly.

If it requires The membrane and the plasterboard than that's what it's gonna get.

The tiler has not seen it yet, or at least I don't think he has, I wonder when he turns up if he would say the tiles were too heavy for the walls as they are or not?

I have 2 young children, and an 8kg tile falling from the wall 8ft up could easily kill I am sure.
