London, United Kingdom. Dual British Cypriot citizens must use a valid British passport when entering the United Kingdom from Wednesday, February 25, according to the Cypriot high commission in London.
Requirement linked to ETA rollout
The measure coincides with the full rollout of the UK’s electronic travel authorisation (ETA) system for non-British nationals, prompting authorities to clarify travel rules for dual citizens.
UK position on dual nationals’ travel documents
The UK government allows dual nationality, but officials said travel to Britain must be on a UK passport. A Home Office spokesperson said dual nationals have previously been able to enter on non-British passports due to limited enforcement, but this is no longer technically permissible.
ETA use and potential offence
Authorities said those attempting to use an ETA with a non-British passport would be unable to proceed if they declare themselves British, and misrepresenting nationality is a criminal offence.
Certificate of entitlement as alternative
Officials said the only alternative to a British passport is a certificate of entitlement, which confirms the right of abode in the UK and does not require an ETA. The certificate must be renewed with each new passport and costs £589 (€679.65).
Fraud and security concerns
The House of Commons library said the requirement reflects concerns over fraud and security, noting that passports carry biometric data and certificates of entitlement are linked to them.
Border delays and compliance advice
Officials warned that dual nationals travelling without a valid British passport could face delays at the border while proving their nationality. The British government said no additional enforcement operations are planned but recommended strict compliance to avoid complications.
