Children are not necessarily allowed in all pubs and restaurants unless a lounge area is provided, and high chairs are not always available. British pubs and restaurants are subject to complex licensing laws and it is illegal for children under 16 to enter licenced premises unless accompanied by an adult. Under 18s may not purchase or consume alcohol, and it is an offence for them to do so. It is also an offence to serve them or for an adult to buy drinks for a minor. An exception is that 16-17 year olds may consume beer, wine or cider with a meal.
Licensees have discretion as to whether or not to allow children into their premises. Most pubs that serve food will accept children, and it is usually easy to distinguish those that do. The general rule is that children cannot sit or stand about in the area where drinks are being served. So if the pub has only one small room, they are often not allowed.
Children are permitted in most drinks-only pubs, especially those with gardens, but again, they are not supposed to come near the bar. To be safe, ask an employee or telephone the place in advance.
