Recent changes to UK border regulations means that travellers with dual citizenship need to pay closer attention to the passport they use when entering the United Kingdom.

update: dual citizen uk passport holders

Since 25 February 2026, British citizens who hold another nationality must now present a valid UK passport when travelling to the UK. Using only a foreign passport is no longer sufficient for boarding flights, ferries or trains bound for Britain.

If a traveller does not have a valid UK passport, they must carry a Certificate of Entitlement to the Right of Abode, which confirms their right to enter the country and is attached to their other passport. Without one of these documents, airlines may refuse boarding before the journey even begins.

While the rule change has caused some confusion, the key message for travellers is preparation. Dual nationals should check the validity of all passports well ahead of travel, ensure names and personal details match across documents, and allow time for renewals or applications where necessary.
