British dual nationals travelling to the UK will soon face stricter entry requirements, as the government prepares to introduce new passport rules tied to its expanding Electronic Travel Authorisation (ETA) system.
The updated measures, coming into force on 25 February, will require all British citizens — including those who hold another nationality — to enter the UK using a valid British passport or a certificate of entitlement. Using the passport of their second nationality will no longer be accepted at the border.
🔍 What’s changing?
Under the new rules:
- Dual citizens must present a current British passport to enter the UK.
- A non-British passport — even from visa‑exempt countries like EU states, Canada, or Australia — will no longer be sufficient.
- Those unable to show a British passport may be refused boarding, face additional checks, or lose access to e‑gates.
- A certificate of entitlement, proving the right of abode, remains an alternative — but it is costly (£589 when issued abroad) and must be renewed with each new passport.
The Home Office says the change is part of its wider rollout of the ETA scheme, which aims to digitise and tighten border controls.
A spokesperson said the system will “ensure millions of people enjoy a more seamless travel experience” while giving authorities “greater power to stop those who pose a threat”.
🛂 What are the rules today?
The UK recognises dual citizenship, and until now there has been no legal requirement for British nationals to enter the country using a British passport.
Many dual citizens routinely travel on their other passport, especially if it offers visa‑free access. Border officers have typically accepted alternative proof of British status, such as:
- an expired British passport
- a naturalisation certificate
- a certificate of entitlement
- proof of right of abode
This flexibility will end on 25 February.
🧭 Why the change?
The ETA scheme — similar to the EU’s upcoming ETIAS system — requires most non‑British, non‑Irish visitors from visa‑exempt countries to obtain digital travel authorisation before departure. It costs £16 and is valid for two years.
British and Irish citizens are exempt from ETAs, but the government says the new passport requirement is necessary to ensure the system functions consistently and securely.
💷 What will it cost?
- British passport (adult): £94.50
- Irish passport: €75
- Certificate of entitlement: £589 (outside UK/Ireland)
For many dual nationals, renewing or obtaining a British passport will be the simplest option.
✈️ What does this mean for travellers?
The changes do not affect citizenship rights — British nationals still have an automatic right of entry.
However, the evidence required to prove that right is becoming stricter.
Carriers may refuse boarding if passengers cannot present the correct documents, as airlines face fines for transporting travellers who do not meet entry requirements.
📌 What should dual citizens do now?
The Home Office is urging dual nationals to:
- Check the validity of their British passport well ahead of travel
- Renew it if necessary
- Avoid relying on their second passport for UK entry
With the new rules just weeks away, preparing early will help avoid delays, complications, or denied boarding.
