British dual citizens may be denied entry without UK passport

British dual citizens visiting the UK without a British passport could soon face entry restrictions, as new rules come into effect next month.

From 25 February, British nationals travelling from abroad will be required to present either a current UK passport or a certificate of entitlement to verify their status when entering the country. Those unable to provide either document will need to apply for an Electronic Travel Authorisation (ETA) using their other passport (if applicable).

Previously, dual citizens were permitted to travel to the UK on a non-British passport and could, if necessary, prove their citizenship with supporting documents.

The UK Government has stated that digitising the immigration system through ETAs will provide millions of travellers with a more seamless entry experience. ETAs also enhance the government’s ability to prevent individuals who pose a threat from entering the country and allow for a more comprehensive understanding of immigration patterns.

What are the new rules?

The changes form part of the Home Office’s new ETA scheme, which will require visitors from visa-exempt countries to obtain an ETA before travelling to the UK. While British and Irish citizens are exempt from
the ETA requirement, they must now travel on a British or Irish passport or present a certificate of entitlement.

Who is affected?

The new entry requirements apply to all dual citizens who live or travel abroad. However, citizens travelling on or before 24 February may continue to enter the UK using a valid non-British passport. It’s also important to note that these requirements apply if you have been granted British nationality but have not yet obtained a British passport.

Costs

A standard adult British passport currently costs £94.50, while an Irish passport currently costs €75. The cost of applying for a passport from overseas is slightly higher. A certificate of entitlement, which is issued within a foreign passport to confirm the holder’s right to live and work in the UK, currently costs £589.

Why are these changes being introduced?

A House of Commons briefing noted that, although there is no legal obligation for British citizens to travel on a UK passport, pre-departure checks have made it increasingly difficult to enter the UK without one. The Home Office has advised dual nationals for several months to use a British passport when entering the UK. Until now, this guidance was not strictly enforced to allow travellers time to adjust.
