The United Kingdom has introduced a new regulation for dual nationals, making it mandatory for British citizens holding dual nationality to enter the country on a valid British passport from February 25, 2026.
The Home Office has warned that after the deadline, dual citizens will only be allowed to enter the UK if they possess a British passport. Otherwise, they may be denied boarding on flights, ferries or trains bound for Britain.bn
Under the new rules, all travelers will also be required to obtain an Electronic Travel Authorization (ETA), carrying a fee of £16.
If a dual national wishes to travel on their non-British passport, they must apply for a “Certificate of Entitlement,” which costs £589. The requirement has drawn criticism from several individuals who describe the fee as expensive and unfair.
According to the Home Office, the move is part of the government’s “digital border system” aimed at making travel more secure and streamlined. However, many families and European residents have expressed concern, arguing that the rules are being implemented immediately and that acquiring two passports could be financially burdensome.
The rights group The3million has urged the government to introduce a cheaper and more accessible alternative to the costly certificate system.
