New UK passport rules coming into force on 25 February 2025 will require dual British nationals, including children, to hold a valid British passport or pay £589 for a certificate of entitlement to enter the country. Previously, dual nationals could use their non-British passport without cost, but they will now be barred from using an Electronic Travel Authorisation (ETA) as an alternative.
The changes mean that dual nationals without a British passport or certificate of entitlement risk being denied boarding on flights, ferries or trains to the UK. A British passport costs around £95 for a standard online adult application in the UK, with higher fees overseas. The certificate of entitlement, which is attached to the second nationality passport, costs £589.
The Home Office said the move is part of a scheme to create a 'seamless travel experience' and give the government 'greater power to stop those who pose a threat from setting foot in the country'. However, some dual nationals have criticised the short notice and poor communication of the changes, fearing holidays or work trips could be disrupted.
Reports suggest some expats have renounced their British citizenship in response, though a declaration made internationally does not, under UK law, revoke British nationality. If British nationality is detected during passenger verification, a dual national travelling solely on a foreign passport may face refused boarding unless they can prove their status with a valid British passport or certificate of entitlement.
From 25 February 2025, all dual British citizens must present either a valid British passport or certificate of entitlement when travelling to the UK. Without one, carriers cannot verify their British citizenship, which may lead to delays or refused boarding. Public information has been available since October 2024, and a communications campaign about the introduction of ETA has been running since 2023.
