And read recently on the BG website that any plaster used which was bonded with pva the tile limits (as BG state) should be only hold a tile weight of 12.5 kg m2.

I can't believe not only is the DIY Doctor recommending you do it, there's a link mid way through the video selling the PVA haha! Whaaaaaat?!

I'm doing a night course in plastering at the moment and I asked the instructor the exact same thing.
It just seemed odd that I could prime a rendered wall with PVA skim it with finishing plaster then stick over 20kgs of tiles to that plaster???
He just said that's the way it's done and always has been.

One thing that is a concern to me is they skim over all sorts of old paint and old crap!

So what would 12.5kgs m2 equate to in thickness of tile??
Probably negates the use of anything but 6x6 white Pilkingtons.
