Changes to UK passport rules for dual citizens

British dual citizens may face entry refusal at UK borders if they do not present a valid British passport, following new Home Office regulations effective February 25. While they are exempt from the Electronic Travel Authorisation (ETA) requirement for non-visa countries, they must enter the UK on a British passport or obtain a costly certificate of entitlement. Airlines can refuse travel if documentation is not in order, and it is advised that dual nationals ensure their British passport is up to date.
