That was a requirement under the old Licensing Act 1964 which was repealed in November 2005. It is no longer necessary. There is now a Premises Licence Holder, which can be a company or an individual and they may never visit the premises. The pub will also need a Designated Premises Supervisor in day to day charge but they may be an employee and, again, do not have to be in the premises at all times. However, a summary of the Premises Licence must be on display. The details of the DPS are not displayed on it. There are some details on the council public register which you have a right to see but different authorities interpret the requirement differently. Why do you ask?
