I am doing a job in a building that has just been built. The

Who laid the floor? - whoever it was, get them back and tell them to
get it fixed...there are no such thing as tolerances in pouring
concrete, the idea is to stop when it's full to the desired level,
although if this 30mm deviance is over a large area, IE, the floor
area of a house, then this is generally accepted.

Only if you have the house built by a bunch of incompetent monkeys

No, it's accepted everywhere, get a long straight length of timber and a
spirit level and you'll soon find discrepancies in your own (and everyone
elses) house

BTW, 10mm and 21mm lower and higher than what exactly?

The datum.

Is that above or below the DPC?
