I think the 1mm a day only holds for relatively thin depths? if you have it deep to say bury UFH then it increases. Ours took months to go off enough to be able to lay LVT on.
edit: 1mm a day for under 50mm, 0.5mm a day over 50mm is I think what we worked with.

I'd definitely try and ask for quicker drying screed if I move and renovate/extend again.
Various knock on effects of having big gaps between plumbers/electricians/kitchen fitters/carpenters means that I've had the kitchen installed now for almost a month, and the plumber is coming to connect gas hob, complete sink and plumbing work only this Friday.
And I've missed the window of time for our decorator who is now on 2 weeks holiday, and has a 2 week job booked in somewhere else when he gets back.

Rule of thumb for screed is that it cures at approx 1mm a day. I forget how long it is unusable for.
Fast drying screed such as Ardex A38 is walkable from 3hours and ready for floor coverings from 4. Clearly more expensive than regular screed but a no brainer.
