Slopping floors, what is normal?

New build just over a year old but all the floors slope approximately 12mm in 1m distance from the door frames downstairs. The picture show a spirit level with 2 drinks coasters required to make it level when it is laid 90 degrees from the door frame. Other floor areas downstairs are the same. Is this within what would be considered normal tolerance?

the standard is 5mm in 2m with equal offsets for a builders floor under nhbc guidelines

however if your fitting amtico or karndean ....then you are going to need around 2mm max deviation ...so self levelling will normally be required

Thanks for the reply, our floors seem well out of tolerance then. The living room is 4m wide and drops by 12mm in the centre from either side. When the joiner fitted the flooring he had a few issues and said here nothing was level. Not sure whether to bring this up with them or not? Lots of other issues that haven’t been remedied and it’s very frustrating.
