Alcohol and the law
Even though it’s not illegal to drink alcohol at home if you’re under 18, it’s healthier if you don’t. If you do want to drink, you should only do it with a parent or another responsible adult.
It is illegal to try and buy alcohol at a bar or at any shop until you reach 18. It’s also against the law for anyone to try and buy it for you.
You’re actually allowed to go into family areas of a pub from the age of 5, but only if they have a special ‘children’s certificate’. Once you reach 14, you’re allowed to go anywhere in a pub, but you won’t be able to buy any alcohol.
16 and 17-year-olds can order and drink beer, wine or cider with a meal at a restaurant or pub where food is served. You can only do this if there is an adult with you.
The police can now stop people under 18 if they think they may be carrying alcohol. If you are stopped and you're carrying alcohol, the police can confiscate it. It's also an offence to be regularly found in possession of alcohol.
