Sorry for missing your point, but as Saki said "a little inaccuracy sometimes saves tons of explanation" !
The phrase 'valid until' as used in UK ratings IS inclusive. A rating valid until 30th, is valid until midnight on 30th, not midnight on 29th.
I'm not defending the CAA's grammar because I acknowledge it has the potential for confusion, and have asked this very question in the past as a result. Try negating the statement 'valid until 30th', and I suggest you'd probably say 'not valid after 30th'. That would more clearly point to the intended meaning.
