Travellers entering or leaving the UK with large amounts of money may be required to declare it to customs authorities before or upon arrival.

Under UK customs rules, anyone carrying £10,000 or more between Great Britain — England, Scotland and Wales — and a country outside the UK must make a declaration.

The requirement also applies to families or groups travelling together. If the combined amount being carried by the group is £10,000 or more, a declaration is required even if no individual traveller has £10,000.

Travellers can make a declaration up to 72 hours before their journey.
