UK dual citizens face new entry rules starting February 25, 2026, tied to the Electronic Travel Authorisation (ETA) rollout.
What are the new rules for dual British citizens entering the UK?
From February 25, 2026, British and Irish dual nationals must enter the UK using a valid British passport, Irish passport (if applicable), or a foreign passport with a Certificate of Entitlement (COE).
Airlines will enforce this at check-in to avoid fines, refusing boarding without proper documents. Dual citizens cannot obtain an ETA with their non-UK passport, as ETAs apply only to non-British/Irish nationals.
Why did these changes happen?
The Home Office links these rules to the full ETA scheme launch, which requires visa-exempt travellers from 85 countries to get a digital £16 authorisation valid for two years. Automated checks at booking and check-in ensure compliance, preventing threats and tracking patterns.
Previously, dual nationals could enter freely with passports from countries like Australia, Canada, or EU nations without declaring British status.
How much does it cost?
A standard adult British passport renewal costs £94, while a COE from outside the UK or Ireland is £589 and needs renewal per new passport issued. Irish passports cost around €75. Without these, travellers risk extra scrutiny, denied boarding, or border refusal.
Who does it affect?
Over one million British dual nationals abroad, especially those relying on non-UK passports for convenience, must prepare now. The UK still fully recognises dual citizenship, preserving rights like abode – no renunciation is forced. Home Office urges early action to avoid travel disruptions.
Does this affect my dual citizenship status?
No, the UK fully recognises dual nationality. No need to renounce anything; these are just entry document requirements.
Who needs to act now?
Over one million dual nationals abroad, especially those using foreign passports habitually. The Home Office recommends renewing passports early to dodge travel chaos.
