The alcohol licensing laws of the United Kingdom regulate the sale and consumption of alcohol, with separate legislation for England, Wales, Northern Ireland and Scotland being passed, as necessary, by the UK parliament, the Senedd in Wales, the Northern Ireland Assembly, and the Scottish Parliament respectively. The minimum age at which people are legally allowed to purchase alcohol is 18. Adults purchasing alcohol on behalf of a person under 18 in a pub or from an off-licence are potentially liable to prosecution along with the vendor.
