LONDON, United Kingdom — A new UK dual national travel rule set to take effect on Feb. 25, 2026, will change how British citizens with dual nationality enter the country. Under the updated requirement, dual nationals will be expected to use a valid UK passport when travelling to the UK.
Authorities say travellers who try to board flights using only the passport of their second nationality may face delays or be denied boarding. Officials said travellers without a valid UK passport could still be permitted to travel if they can show official proof of their right to live in the UK.
That proof may include a certificate of entitlement or right of abode documentation, authorities said. Officials advised dual nationals travelling after Feb. 25 to ensure their documents are in order to avoid disruption.
Carriers to verify documents before departure
The change will place more responsibility on airlines and other carriers to verify documentation before departure. Under the updated process, carriers will be expected to confirm that British citizens with dual nationality are presenting the correct documents before allowing them to travel to the UK.
Officials said the move is designed to streamline entry procedures at UK ports while improving border security. For travellers, it means documentation issues could be raised at check-in or the boarding gate rather than on arrival.
How the UK dual national travel rule fits the ETA rollout
Authorities said the UK dual national travel rule is part of the government’s wider push toward a fully digital border system and enhanced travel checks through its Electronic Travel Authorisation programme, known as ETA.
Officials said the updated approach supports a more digital, pre-travel screening process by ensuring travellers present documentation that clearly confirms their UK status. Dual nationals planning travel after Feb. 25 are being advised to hold a valid UK passport and any appropriate supporting documentation well ahead of departure.
