Dual British–Cypriot Nationals now required to use UK passports for entry into the United Kingdom

A significant change affecting dual British–Cypriot nationals has now come into effect. As of 25 February 2026, individuals who hold both British and Cypriot citizenship must enter the United Kingdom exclusively using their British passport. This update follows new guidance issued by the UK authorities and communicated publicly by the Cyprus High Commission in London.

What Has Changed

Under the UK’s updated border entry rules, dual nationals are no longer permitted to enter the country using their non‑UK passport. Even if a traveller holds a valid Cypriot passport, they could face denial of entry unless they present a valid British passport at the border.

This change is closely linked to the rollout of the Electronic Travel Authorisation (ETA) system, which now applies to all non‑visa nationals entering the UK. While Cypriot citizens normally fall under the ETA scheme, British citizens are exempt. The UK government has therefore clarified that dual nationals must enter as British citizens, not as EU nationals.

Practical Implications for Travellers

Dual British–Cypriot nationals should take note of the following:

• A British passport is now mandatory for entry, regardless of whether the traveller also holds a Cypriot passport.
• Travelling with only a Cypriot passport may result in denied boarding by airlines or refusal of entry upon arrival in the UK.
• The requirement applies to all forms of travel—air, sea, and land.
• The rule does not affect the right of abode or immigration status of British citizens; it only concerns the document used for entry.

Alternative Proof of Right of Abode: Certificate of Entitlement

The UK recognises only one alternative to a British passport for proving the right of abode: the Certificate of Entitlement. This certificate is affixed to a foreign passport and confirms that the holder has an unrestricted right to live and work in the United Kingdom. Importantly, individuals travelling with a Certificate of Entitlement do not require an ETA.

However, the certificate:

• must be reissued each time a new passport is obtained, and
• currently carries a fee of £589 (€679.65).

While legally valid, this option is significantly more costly and administratively burdensome than maintaining a valid British passport.

Why the UK Implemented This Requirement

The UK’s ETA system is designed to enhance border security and streamline entry procedures. Since British citizens are exempt from ETA requirements, the UK government now requires dual nationals to enter using their British identity to ensure consistency with the system’s legal framework.

This approach aligns with practices in other jurisdictions, where dual nationals are often required to use the passport of the country they are entering.

Recommended Actions for Affected Individuals

It is important for everyone who hold both nationalities to:

• Check the validity of their British passport well in advance of travel.
• Apply for renewal early, as processing times may vary.
• Avoid relying on their Cypriot passport for UK entry, even if it is more convenient or recently issued.

For families with children who hold dual nationality, it is essential to ensure that minors also possess valid British passports before travelling.
