The UK government has quietly updated its passport entry rules for dual citizens, allowing British and Irish nationals to travel to the United Kingdom using an expired British passport under temporary measures. However, the decision is left to the discretion of airlines and other carriers, raising concerns about confusion among travellers.
Previously, dual UK–Irish citizens were required to carry a valid British or Irish passport, or obtain a Certificate of Entitlement, to board flights, ferries, or international trains. Under the new guidance issued by the UK Home Office, carriers may now accept an expired British passport issued after 1989, provided travellers also hold a valid passport from another nationality eligible for the Electronic Travel Authorisation (ETA) system.
According to the updated rules, personal details on both passports must match, and travellers may still be subjected to additional identity checks upon arrival in the UK. The Home Office has not clarified when the changes were implemented, leading to criticism over poor communication.
Industry leaders have warned that the policy could create further uncertainty. Australian Travel Industry Association CEO Dean Long described the situation as confusing, noting that airlines may adopt different approaches when accepting expired British passports. He also urged the UK government to extend the upcoming February 25 deadline, highlighting the stress and disruption faced by thousands of travellers unaware of their citizenship status.
