Expect to see it from July 5th....
Couple of people I know who run bars, actually small music venues but small enough to come under pubs and bars, have only had information from their brewery and local licensing unit.
On the face of it that would make sense except they have made clear they are essentially best guessing as there's been no information passed to them. Obviously causes problems if the official advice doesn't turn out to be in line with what they're working to. For example they've been working on the basis of 2m distancing, now there's talk of it being changed but they can't even get a definite answer on when the review of the rule will be completed.
