The law does not require doorman in licensed premises. It may be imposed as a condition on the particualr premises licence by the Council if it is felt, following consultation, representation and hearing, to be necessary. If doormen are required in these circumstances, they must be licensed by the SIA.
If a room in the pub is licensed and alcohol is sold there, there is no problem. If the room is not included on the premises licence plan, it must have another authorisation, such as a temporary event notice, to legalise the sales.
