As part of the introduction of the next phase of the Electronic Travel Authorisation (ETA) scheme, the UK has changed the rules of entry for individuals that hold dual British nationality.

Currently dual nationals can travel to the UK using either of their passports, however, from 25 February they must provide evidence of their British nationality to be granted entry to the country.

This means that dual nationals – whether claimed by descent or by living overseas – must have a valid British passport or a ‘certificate of entitlement to the right to abode’ to travel to the UK.

The simplest way to do this is to apply for or renew their British passport. Given that HM Passport Office suggests that online applications take around three weeks – longer if the application is from overseas – individuals with plans to travel to the UK may need to act quickly.

For individuals who aren’t able to obtain a passport in the relevant time frame or would prefer to travel on the their non-British passport they can apply for a certificate of entitlement. This process takes eight weeks, according to gov.uk.

UK citizens who do not have a valid British passport, or a certificate of entitlement, risk being refused boarding on their flight or entry at the border from 26 February.

The only exceptions to these changes are UK citizens who hold Irish nationality. Individuals travelling on an Irish passport will not need to offer proof of their British citizenship to be granted entry to the UK.

What about the ETA?

The ETA scheme was introduced in October 2023 and enables individuals from countries that do not need a visa to enter the UK (such as, Europe, US and Canada) to travel for tourism or visiting family for up to six months.

From 25 February travellers from ETA-eligible countries will only be allowed to travel to the UK if they have purchased an ETA.

British and Irish citizens cannot apply for an ETA, they must travel with proof of their Irish or British nationality (ie, a valid passport).
