British Standard help!

I am trying to put together a quote and letter for a customer who wants to rip up and replace 45sqm of newly laid polished porcs.

The builder (yes-builder!) has done a pretty terrible job with deviations in height of up to 3mm from one tile to the next. Used a 5mm trowel - 20% coverage / no spacers / damaged tiles etc etc etc...

What is the acceptable deviation for floors by BS?
My memory says 2mm over 2m but is this correct?

Anyone know please?

The acceptable deviation is about 3mm in a 1mtr run but this is for the substrate....the tiling it's self should be flat...doesn't have to be level , just flat.....

Is there a website/page that states tiling b/s???

Dave - thanks but that's confused me! If the tiling isn't flat - how can it be level?

What's the difference?

(I think I might have a touch of the stupids today)

tiling can be flat but can still slope can't it(think that what he means)

Flat is smooth flat tiling........level is true in level by using a spirit level......some floors etc are very flat..like a bowling green...but stick a level on it and it is out of level....

Of course - thanks guys.

I do have a touch of the stupids it seems:joker:
