New 2026 UK ETA Rules: How British Dual Citizens Can Travel

The introduction of the UK’s Electronic Travel Authorisation (UK ETA) system in 2026 marks a significant shift in how travellers enter the United Kingdom.

While the system is designed to enhance border security and streamline entry for non-visa nationals, it has created unexpected complications for British dual citizens.

In particular, the new dual national UK rules mean that many British dual nationals can no longer travel to the UK using only their non-British passport. This has caused confusion for individuals who have, for years, travelled freely using a second nationality.

This blog explains what has changed, why it matters, and what your options are if you are affected by the UK ETA dual nationals framework.

What has changed for British dual nationals in 2026?

Under the new UK ETA requirements, travellers from visa-exempt countries must obtain an electronic travel authorisation before boarding a flight to the UK. This applies to nationals of countries such as Australia, Canada, the United States, and EU member states.

However, a key issue arises for dual national British passport holders.

British citizens are not eligible to apply for an ETA because they are not subject to immigration control. At the same time, airlines are now required to verify that passengers travelling on non-British passports hold a valid ETA before allowing them to board.

This creates a conflict:

• If you travel on your foreign passport, you are required to hold an ETA
• If you are a British citizen, you cannot obtain an ETA

As a result, the new passport rule effectively requires dual nationals to prove their British status when travelling to the UK. Simply relying on a non-British passport is no longer sufficient.

This represents one of the most important UK dual citizen passport changes in recent years.

Why British citizens cannot apply for an ETA

The UK ETA system is designed for individuals who require permission to enter the UK but do not need a visa.

British citizens fall outside this system entirely because they have the right of abode in the UK. This means they have an automatic right to live in and enter the UK without restriction.

Because of this status:

• British citizens cannot apply for an ETA
• There is no mechanism to “override” this restriction
• Airlines must still comply with ETA checks for non-British passports

This is the core issue underpinning the new dual national UK rules, as dual citizens are effectively caught between two systems. One requires an ETA, and one prohibits them from obtaining one.

Your options for travelling to the UK as a British dual citizen

If you are a dual national, you now have three main options when travelling to the UK:

• Travel using a valid British passport
• Travel using an expired British passport (in limited circumstances)
• Apply for a Certificate of Entitlement to the Right of Abode

Each option has its own requirements and practical considerations, and it’s important to understand the limits of your personal circumstances before deciding on the best course of action. Here, our solicitors have outlined what each option might mean for you.

Option 1: travel on a valid British passport

The simplest and most reliable solution is to travel using a valid British passport.

This avoids all issues relating to the UK ETA, as British citizens are exempt from immigration control and do not need prior authorisation to enter the UK.

If your British passport has expired or you do not currently hold one, you should consider applying for or renewing it well in advance of travel.

Benefits of this approach include:

• No need to apply for an ETA
• No risk of being denied boarding
• Clear proof of your right of abode

For most dual nationals who are British passport holders, this is the recommended route.

Option 2: using an expired British passport (temporary measures)

In response to the disruption caused by the UK ETA rollout, temporary and discretionary measures have been introduced by some airlines.

Under these measures, you may be able to travel using:

• An expired British passport (typically issued after 1989), and
• A valid foreign passport

This is not a formal legal right but rather a practical workaround applied on a discretionary basis. Airlines may accept this combination as evidence that you are a British citizen and therefore exempt from ETA requirements.

However, there are important limitations:

• Not all airlines may accept expired British passports
• The policy is subject to change at short notice
• You may still face delays or additional checks

If you rely on this option, you should always check with your airline before travelling.

Option 3: certificate of entitlement to the right of abode

If you are unable to obtain or renew a British passport, another option is to apply for a certificate of entitlement right of abode.

This is a vignette (sticker) placed in your foreign passport confirming your right of abode in the UK.

Key points include:

• It proves your status as a British citizen or qualifying individual
• It allows you to travel without needing an ETA
• It is currently priced at approximately £589 (subject to change)

The application process involves submitting evidence of your British citizenship and attending a biometric appointment.

While this is a more expensive and time-consuming option, it can be essential for those who cannot obtain a British passport.

Exceptions: who is not affected by these rules?

British-Irish dual nationals

British-Irish citizens can continue travelling to the UK using their Irish passport. Ireland is part of the Common Travel Area, and Irish citizens are not subject to the ETA requirement.

EU Settlement Scheme (EUSS) holders

Individuals with status under the EU Settlement Scheme do not need an ETA and can continue to travel using their registered passport.

If you fall into either of these categories, your existing travel arrangements are unlikely to change.

What happens if you arrive without the correct documentation?

If you attempt to travel to the UK without the correct documentation, the most immediate risk is being denied boarding by your airline.

Airlines are responsible for checking ETA compliance before departure. If you present a non-British passport without an ETA, they may refuse to allow you to travel, even if you are a British citizen.

In some cases, this can result in:

• Missed flights
• Additional costs
• Significant travel disruption

For this reason, it is essential to ensure you have the correct documentation before travelling.

Frequently asked questions about the new UK ETA rules

Can I still travel to the UK on my Australian/Canadian/EU passport?

No. Under the UK dual citizen passport rule, you cannot rely solely on your foreign passport unless you have an ETA, and British citizens cannot obtain one.

You will need to travel using a British passport or a certificate of entitlement to the right of abode.

How long does it take to get a British passport?

Processing times can vary, but standard applications typically take several weeks. During peak periods, delays are common. You should apply well in advance of any planned travel.

What if my British passport has expired?

You may be able to travel using an expired British passport (issued after 1989) alongside a valid foreign passport under temporary discretionary measures.

However, this is not guaranteed and depends on airline policies.

How much does a Certificate of Entitlement cost?

The current fee is approximately £589, although this may change. Additional costs may apply depending on where you apply from.

Do British-Irish dual nationals need to do anything different?

No. British-Irish dual nationals are exempt from the UK ETA requirement and can continue travelling using their Irish passport.

I have EU Settled Status – do I need an ETA?

No. Individuals with status under the EU Settlement Scheme are exempt from the ETA requirement and do not need to change their travel arrangements.

Can I apply for an ETA as a British citizen?

No. British citizens are not eligible to apply for an electronic travel authorisation because they are exempt from immigration control.

What documents should I carry when travelling?

You should carry:

• A valid British passport (preferred), or
• An expired British passport and valid foreign passport (if relying on temporary measures), or
• A certificate of entitlement to the right of abode

Carrying supporting documentation can also help avoid delays.
