I think British Standard is compiled by a few old men and industrial standards is what I commonly do 😁

Still need a bit more information, what type of liquid screed?

This is what I have from the person who installed it.
“self-compacting anhydrite floor screed”

If it helps I have a block and beam floor then insulation then screed. There’s some damp proof in between too.

You need a gypsum-based adhesive to fix the ditra after first removing any laitance
or you could go with ball Flexi bone
