TIGHTENING OF RULES FOR TRAVEL TO AFFECT DUAL BRITISH NATIONALS WHO HAVE NO BRITISH PASSPORT
If you have British Citizenship and plan to travel to the UK on or after 25th February 2026, make sure that you first have a British passport or a certificate of entitlement in your non-British passport. It is unlikely that you will be permitted to travel without either of these, even if you have a certificate of naturalisation.
This won’t affect Dual British/Irish Nationals who will still be able to travel to the UK using an Irish passport.
