Your passport or identity card will be checked when you arrive at a UK port or airport to make sure you’re allowed to come into the country. It must be valid for the whole of your stay.
There has been no change to the rights and status of EU nationals in the UK, and UK nationals in the EU, as a result of the referendum.
What you can bring with you depends on where you’re travelling from. You must declare to customs:
- anything over your duty-free allowance
- banned or restricted goods in the UK, eg meat and dairy products from most non-EU countries
- goods that you plan to sell
- more than €10,000 (or its equivalent) in cash, if you’re coming from outside the EU
You and your baggage may be checked for anything you must declare.
