We’ve received a recent update regarding UK dual citizenship and travel documentation, which may be relevant for some travellers planning international travel.
Important Reminder for Dual Nationals – UK changes
What is a dual national? A dual national holds nationality in more than one country. Whether you’re a dual national depends on the laws of both countries. When you’re a dual national, it’s important to understand how each country expects its citizens to enter and exit.
The United Kingdom is making changes that apply to Dual Citizens which come into effect on 25 February 2026 – an overview of the changes is below – please read and understand how these changes might impact your customers:
Do British dual citizens need an ETA?
- Dual citizens with British or Irish citizenship are exempt from needing an ETA.
- Dual British citizens must have a valid British passport or certificate of entitlement when travelling to the UK. UK passports can be renewed at GOV.UK
- We strongly advise dual British citizens to make sure they have a valid British passport or Certificate of Entitlement, to avoid problems like being denied boarding when travelling to the UK from 25 February 2026.
- From 25 February 2026, dual British citizens who cannot produce a valid British passport or certificate of entitlement will need to have additional identity checks and will not be able to go through UK passport control until their British nationality is verified.
- Further information for dual British citizens can be found on GOV.UK
If you hold dual citizenship involving the UK (for example, UK & New Zealand), it’s important to ensure you’re travelling with the correct passport and are aware of the latest entry and exit requirements.
There is another option to having a UK Passport (which some media are reporting as the only option), that is the certificate of entitlement there is some good info on this link (snapshot below), including the cost which is £589.

ETA:
Since 8 January 2025 an electronic travel authorisation (ETA) is required for New Zealand passport holders, including other eligible non-European countries, to travel to the UK for tourism, for visiting family or certain other reasons for up to 6 months. The ETA process can be found HERE on the gov.uk website
Who needs an ETA:
- Travellers going to the UK for tourism, visiting friends & family, or certain other reasons for up to 6 months
- Those transiting through the UK and passing through UK border control
- You usually need an ETA rather than a visa if you’re from Europe, the USA, Australia, Canada or certain other countries.
ETAs will cost GBP16 and are usually granted within 3 business days. On some occasions it may take longer. ETAs are valid for two years or until passport expiry, whichever is sooner. You can travel to the UK as many times as you like whilst the ETA remains valid.
ETAs have been compulsory for New Zealand passport holders arriving in the UK on or after 8 January 2025. Other nationalities, including dual citizens, may have different obligations with regard to ETAs.
Who CAN’T enter on an ETA:
You can’t enter on an ETA if you have any, or are eligible, for any of these:
- a visa
- permission to live, work or study in the UK
- a valid British or Irish passport
- a valid British Overseas Territories citizen passport
Dual citizens with British or Irish citizenship are not eligible for an ETA even if they do not currently hold a valid UK or Irish passport. Dual citizens will need to prove citizenship using a valid British or Irish passport or valid passport containing a certificate of entitlement for travel.
Why is this on our radar again now?
There has been an initial grace period since the ETA introduction in January 2025, however it will be strictly enforced from 25 February 2026. In the past year, it’s possible that dual citizens may have been able to enter the UK with or without a valid British or Irish passport, either on an ETA, or without being required to prove their British or Irish citizenship. Therefore, from 25 February 2026 it’s crucial dual citizens carry both NZ & UK or Irish valid passports (or appropriate documentation for their personal circumstances) for successful travel.
How do I know if this applies to me?
If you are unsure how this applies to your personal circumstances, such as nationality, citizenship or passport eligibility, please refer to the gov.uk website for comprehensive advice including relevant contacts such as the HM Passport Office (HMPO). We cannot give any advice on your personal circumstances.
