Several of these replies are more or less right. The applicant for a Premises Licence stipulates on his application the time to which alcohol will be sold and any different times when the public will be on the premises. It could be 30 minutes or an hour or even longer either after or before the alcohol is sold. However, two things arise. Firstly, many licences were transferred under Grandfather Rights without amendment and the previous terms still apply (20 minutes drinking up or 30 where special provisions apply). There is, however, nothing to stop the landlord having people in his premises 24 hours a day so long as they aren't drinking alcohol. Second, the law now licenses only the sale of alcohol, not its consumption. So, if all the public are doing is drinking beer they bought earlier, it is open to question whether, if this is beyond the stated time, an offence has been committed. This has not yet been tested in court.
