UK Dual Citizens Must Act Fast Ahead of New Passport Requirements

26 Jan UK Dual Citizens Must Act Fast Ahead of New Passport Requirements

British citizens holding dual nationality need to act quickly as the UK introduces new entry rules. Starting February 25, 2026, travelers must present a valid UK passport or a certificate of entitlement to enter the country. Those without the correct documents could be refused boarding by airlines, ferries, or trains.

What’s Changing?

Previously, dual nationals could use a foreign passport to enter the UK or provide alternative documents to show their citizenship. Under the upcoming Electronic Travel Authorisation (ETA) system, all travelers — including dual citizens — must demonstrate their right to enter the UK.

Key points:

• British and Irish citizens must now travel with a UK or Irish passport or present a certificate of entitlement.
• Anyone relying solely on a foreign passport may need to update their travel documents by February 24, 2026.
• These changes affect people who:
  • Were born British and acquired another nationality
  • Became British through naturalisation or registration
  • Have held dual nationality since birth

Steps Dual Citizens Should Take

To ensure smooth travel:

1. Check your UK passport to confirm it is valid.
2. Apply for a new passport if yours has expired — standard adult passports cost £94.50, children’s passports £61.50.
3. Consider a certificate of entitlement if you want to keep using a foreign passport — costs £589.
4. Allow enough time for processing — UK passports usually take about three weeks to arrive, longer if additional checks are needed.

Pro tip: Begin the process now to avoid last-minute travel disruptions.

Why This Matters

The UK government is moving toward digital border controls, and transport companies are expected to enforce these rules strictly. Passengers without proper documents may be denied boarding, even if they have previously entered the UK on a foreign passport.

Official guidance notes that expired passports or naturalisation certificates are not considered valid for travel purposes. Over 1.2 million people in England and Wales hold multiple passports, meaning a significant number of dual nationals may need to act quickly.

Conclusion

Dual citizens have a limited window to prepare. Whether renewing a UK passport or applying for a certificate of entitlement, planning ahead is essential. Make sure your documents are in order well before February 25, 2026, to guarantee hassle-free travel to the UK.
