From 25 February 2026, the United Kingdom will enforce updated documentation requirements for entry by British and Irish dual citizens as part of the full implementation of its Electronic Travel Authorisation (ETA) system. These changes do not alter nationality law; the UK continues to recognise dual citizenship. What is changing is how dual nationals must prove their right to enter the UK at check-in and border control. Official Home Office guidance confirms that dual citizens must demonstrate their entitlement to travel using specific documents to avoid being denied boarding or subject to additional identity checks.
Under the new requirements, dual British or Irish nationals must enter the UK using one of the following: a valid British passport, a valid Irish passport, or a foreign passport containing a Certificate of Entitlement confirming the right of abode. Dual nationals cannot obtain an ETA with a non-UK passport, as ETAs are available only to non-British and non-Irish visa-exempt travellers.
“while the UK still fully recognises dual nationality, travellers need to ensure they have the correct documentation well before travel to avoid disruption at check-in or at the border”
The requirement stems from the broader rollout of the ETA, introduced to strengthen pre-departure checks and align UK processes with digital entry systems used by other countries, such as the United States and Canada. Carriers are obliged to verify travellers’ entitlement before boarding and may refuse boarding to those without appropriate documents. This enforcement shift means that habitual use of a third-country passport (for example, Australian, Canadian or EU) will no longer suffice for UK entry for dual citizens.
The cost implications vary. A standard adult British passport renewal fee within the UK is currently around £94, while a Certificate of Entitlement, which can be endorsed in a foreign passport, typically costs several hundred pounds and must be renewed with each new passport issuance. Irish passport application fees differ by issuing authority.
These documentation rules intersect with broader trends in global mobility that the financial and mobility community is tracking closely. In IMGlobalWealth.com’s analysis ‘The UK Passport Slides as Fiscal Policy Reshapes Global Mobility Choices’ (published on 16 December 2025), the UK’s position in the Nomad Capitalist Passport Index fell to 35th globally, illustrating how fiscal policy, taxation, and mobility priorities are increasingly influencing decisions by internationally mobile individuals and families. The article argues that passport strength is now viewed as a strategic asset within planning frameworks rather than merely a symbol of national identity.
The practical impact for dual nationals is clear: while the UK still fully recognises dual nationality, travellers need to ensure they have the correct documentation well before travel to avoid disruption at check-in or at the border.
