You can buy and drink alcohol in a bar, pub or club from the age of 18.
From the age of 16 you can enter a bar on your own, but you can only buy non-alcoholic drinks- you will be breaking the law if you try to buy or drink alcohol in a bar, pub or club. If you are 16 and are with someone over the age of 18, you can drink beer, wine or cider with a meal.
