Dual Nationals Face New UK Entry Rule
From 25 February, dual British citizens must present a valid British passport when entering the UK, even if they hold another nationality. The change, confirmed by the Home Office earlier this month, means foreign passports will no longer be accepted on their own. Those without a British passport must instead obtain a certificate of entitlement, which costs £589 and is attached to their other passport.
Anyone attempting to travel without either document risks being refused boarding by their airline and prevented from returning to the UK. Officials have said the rule brings dual nationals in line with other British citizens. An expired British passport may be accepted as alternative documentation, though this depends on the airline and is not guaranteed.
“From February 25, 2026, all dual British citizens will need to present either a valid British passport or certificate of entitlement to avoid delays at the border."
The shift is estimated to affect just over two per cent of the UK population, amounting to more than one million people. Critics say the short notice leaves little time for those living abroad to renew or apply for documents. Dual nationals cannot apply for the new Electronic Travel Authorisation, which launches on the same day and applies only to non-British and non-Irish visitors.
What changes on 25 February
- Dual nationals must show a valid British passport
- Alternative: £589 certificate of entitlement
- Expired British passport may be accepted at airline discretion
- ETA required for eligible foreign nationals (£16)
- ETIAS for travel to Europe expected later this year (£17)
For people with upcoming trips, the key issue is timing. Passport applications can take weeks, and emergency travel documents may not suit every itinerary. Anyone holding dual nationality and planning to return to the UK should check their paperwork before departure. The update adds another layer to an already shifting travel landscape, and missing it could result in denied boarding rather than a simple delay.
