I have to deal with clark of works a lot and the above is exactly right, to simplify it if a pound coin which is 3mm can fit anywhere under a two metre straight edge anywhere on the substrate then the substrate is out of tolerence and a quick tip is to tape a pound coin to both edges of a 2 metre straight edge an use two pound coins on the floorPut a 2m long straight edge anywhere on the plasterboard and if there is any gap greater than 3mm between the straight edge and the board then it is not flat enough to tile.
On the tiled wall do the same test using a 2m straight edge with 3mm feet each end. If the gap between this and the tiles exceeds 6mm or the straight edge touches the tiling then the tiling does not meet BS.
This is based on my memory of reading BS5385 a while ago (I no longer have an up to date copy).
The same tests apply for the flatness of a floor substrate and floor tiling.
On a large floor the surface should also be flat within +/-15mm of the datum or as per the architects specified tolerance. I don't know the equivalent wall building tolerance.
Lol, but that's what comes with the territory with some private jobs I suppose that's why our experience in dealing with crap helps us establish Good reputations were we can more or less name our price within reason.I'm a tiler, not a plasterer.
If I were you and you didn’t want to ditch the job then I’d just charge for my pain. I’m well experienced at dealing with pathetic floors (@John Benton) I’ll do what I have to so long as it makes financial sense. Sooner or later the QS will realise that it’s cheaper to employ professional Screeder’s to do the job properly than to pay you to sort out bad screeds.
I posted yesterday about the poor job that has been made of our shower wall tiles. Since then I’ve become something of an expert on tiling (haha) and have another query regarding our floor tiles. The lippage seems excessive in areas. Photos of the worst area below. Is that acceptable?
Further more this week I’ve found a cracked floor tile that definitely wasn’t there before. No one remembers dropping anything on the floor but it kind of looks like a blunt force from above so I am willing to accept it must be something we’ve done. However, given the poor job elsewhere there’s a slight concern this is due to the way the tiles have been laid?
Bathroom all 7 months old. Will include a picture of when the tiles were being laid.
Thanks!

It's been spot fixed and fixed to ply. Should have been overboarded with cement board, levelled then tiled use a notched trowel.Could you elaborate so I can question them when they come round tomorrow?
By spot fixed do you mean dot and dab? AsFi

Was it a general builder by chance?

They would soon learn to read if guarantee man wasn't signing it off and mortgage man then wouldn't release the money to client who needs it to make stage payment .And you need to remember that most builders cannot read, so the cost of producing picture books that can explain best practise tiling techniques would be very high indeed!
