Does anyone happen to know to what tolerance a concrete floor should be laid - just had one laid myself - supposedly flat and level - it's neither!

try a self levelling screed on it
If you've just had it done and are not satisfied, Speak to the contractor about a partial refund. If that doesn't satisfy either of you, speak with a lawyor.

Generally speaking, if the variation is within 1/2 in twenty feet and within 1/4 in in any eight foot area the job is within industry norms. Larger variations would reflect sub par work.

Skim coating of any slab with less than two inches of new material is really not a good idea if the concrete is going to be visible. We have sometimes found it neccessary to grind floors that were excessively wavy, but that is a tedious, expensive, and very very dusty solution.
