Urgent travel warning for dual British nationals: What you need to know about the UK’s new ETA requirements

Dual citizens with British citizenship could be impacted by upcoming travel changes. From 25 February 2026, the UK’s Electronic Travel Authorisation (ETA) scheme is undergoing significant changes, and failing to travel with the right passport or documentation could lead to denied boarding by airlines.

What is an ETA?

An ETA is a digital permission to travel to the UK. It is not a visa and does not permit entry into the UK – it simply authorises travel to the UK through a flight or other transport. Final permission to enter is still granted by a Border Force officer on arrival. 

As part of the UK’s move towards a more secure and streamlined digital immigration system, visitors who do not require a visa must now apply for an ETA before travelling – unless they already hold UK immigration permission. From 25 February, eligible visitors who do not have an ETA will not be able to travel to the UK. 

Do dual British citizens need an ETA?

Dual citizens who hold British citizenship are exempt from needing an ETA – in fact, they are not eligible to apply. This is because British citizens automatically have the right of abode in the UK – meaning you can live or work in the UK without immigration restrictions. 

To prove your right of abode in the UK, you must hold either a valid British passport or a certificate of entitlement (CoE) in your valid foreign passport. 

A CoE is an official endorsement placed in your foreign passport confirming your right of abode in the UK. It is particularly relevant for dual nationals who prefer to travel on a non-British passport or who do not currently have a valid British passport.

Although dual British citizens do not need an ETA, there is an important practical issue to keep in mind to avoid travel disruption. You must be able to prove your British citizenship using one of the methods above. If you attempt to travel using only your foreign passport — without a CoE — you may face delays or even be denied boarding by the airline.

If you are a dual British citizen planning travel to the UK, it is strongly advised that you check that your British passport will be valid for your travel dates, or apply for a renewal or CoE well in advance. British passport applications are typically processed within three weeks and around eight weeks for CoE applications. Applications made outside the UK may take longer.

The UK’s ETA system is part of a broader move toward digital border control. For most travellers, it is a straightforward additional step before travel. However, for dual British citizens, the key takeaway is simple:

• You do not need an ETA — but you must be able to prove your British citizenship when you travel.
• Planning ahead and ensuring your documents are in order will help ensure a smooth journey to the UK.
