I am a British citizen with a second passport: which document do I use to enter the UK? Do I need an eVisa?

Who does this apply to?

• This is general information. It does not assess anyone's personal situation. It is for people who hold British nationality plus another (for example Turkish) and their families. It is based on the GOV.UK "Entering the UK: Before you leave" and "Travel with your eVisa" pages (October 2026). Turkish entry and exit rules are not covered here.

Which document does a British citizen use to enter the UK?

• GOV.UK says the accepted documents are: a valid UK passport, a Gibraltar identity card, or a certificate of entitlement showing the right of abode in the UK. Each one is a standalone option.
• A British or Irish citizen does not need an eVisa. The eVisa page says British or Irish nationals should travel with their British or Irish passport, or a passport with a certificate of entitlement.

If you hold a second nationality

• GOV.UK says that if you hold UK and another nationality, you may also be able to travel with: an expired UK passport, an emergency travel document, or a non-UK passport or national identity card only if you settled in the UK under the EU Settlement Scheme. The page points to its dual-citizenship guidance.
• The page does not describe other cases of entering on the second country's passport (for example Turkish). In such a case look at the GOV.UK dual-citizenship guidance.

The Turkish side when leaving

• In the groups someone wrote "entering the UK on the British passport and leaving on the Turkish one is no problem, my spouse does it every year". That is personal experience. Turkish entry and exit rules are not GOV.UK's subject; check them with Turkish official sources (the consulate, Population and Citizenship Affairs).

Children

• Which document a child travels on depends on the child's nationality and status. If the child is a British citizen the documents above apply. If the child is not a British citizen and holds permission that needs an eVisa, see the post "Travelling to and from the UK with an eVisa".

Points to watch

• Official pages change. This post is a general summary.

What can you do?

• Read the "You're a British citizen" section of Entering the UK: Before you leave for the UK.
• See the "Dual nationals" section of Travel with your eVisa.
