Do you need a passport to enter the UK? Check the rules for 2026
The UK government has clarified the personal changes that can require British passport holders to apply for a new passport in 2026.
The guidance is particularly important for people planning international travel after changing personal details such as their name or gender.
According to the UK government, a passport holder must get a new passport if their name changes, their gender changes or their appearance changes so significantly that they can no longer be recognised from the photograph on their existing passport.
The rules also explain several situations where a person does not need to replace their passport.
This means that not every major change in a person’s life automatically makes their passport invalid or requires them to apply for a new one.
UK passport rules for people who change their name
One of the main circumstances requiring a new passport is a change of name.
The UK government says the name on a passport must match the name a person uses when booking travel.
This can affect people who change their names through marriage, civil partnership, divorce or another legal process and want to travel using their new name.
A person can apply for a new passport after changing their name. The government also allows people getting married or entering a civil partnership to apply for a passport in their new name before the ceremony under specific arrangements.
For people who have already changed their name, the important point is to ensure that the passport and travel booking carry the same name.
Travelling with different names across travel documents and bookings can create problems at the airport or during immigration checks.
UK passport rules for people who change gender
A change of gender is another circumstance listed by the UK government as requiring a new passport.
The change needs to be reflected in the person’s passport so that the travel document contains their current personal details.
The government has separate guidance for people changing the gender recorded on their passport. Applicants may need to provide evidence depending on their circumstances.
For dual nationals, there is also an additional consideration.
The UK government says the name and gender on a non-British passport must match the name and gender the person wants on their British passport. Where they do not match, the foreign passport may need to be changed first.
Major changes to appearance can require a new passport
A person may also need a new passport if their physical appearance changes so much that they can no longer be recognised from their existing passport photograph.
The government gives plastic surgery as an example of a change that could make a person unrecognisable from their old photograph.
This rule is based on identification rather than simply whether someone looks different from when the passport was issued.
Therefore, people do not need to replace their passports every time their appearance changes.
For example, growing a beard or dyeing one’s hair does not, by itself, require a new passport.
However, where a person has undergone a major physical change and can no longer be identified from the photograph, they may need to apply for a replacement.
Changes that do not require a new passport
The UK passport rules also identify several common life changes that do not require a person to obtain a new passport.
A person does not need a new passport simply because they have:
- Changed their residential address
- Changed their contact details
- Started a new job
- Grown a beard
- Dyed their hair
- Changed their marital status while keeping the same name
- Changed their title
- Become a citizen of another country while retaining British nationality
- Moved abroad or emigrated
These exceptions are important because people may assume that any change in their personal circumstances must be reflected in their passport.
The UK government, however, distinguishes between changes that affect the identity information used on the passport and changes that do not.
Marriage does not always mean a new passport
Marriage is one area where the rules may cause confusion.
Getting married does not automatically mean a person must obtain a new passport.
The key issue is whether the person changes their name.
Someone who gets married but continues using the same name does not need a new passport simply because their marital status has changed.
However, someone who adopts a new surname after marriage can apply for a passport showing the new name. The government requires the relevant marriage or civil partnership certificate when applying after the ceremony.
The same principle applies to divorce and civil partnerships where the person’s name remains unchanged.
What happens to the old passport?
When a person obtains a new passport because of a change in personal details, the remaining validity of the old passport does not transfer to the new document.
The UK government says the new passport will be a standard 10-year passport for eligible adults, while the unused period on the old passport will not be added to the new one.
The new passport will also have a different passport number.
People with valid visas in their old passports should also check with the relevant embassy or consulate because changing personal details can affect the validity or use of an existing visa.
Nigerians travelling to the UK should check their documents
The rules are particularly relevant to Nigerians living in the UK or planning international travel from the country.
A Nigerian travelling to the UK will generally need a valid passport or travel document, alongside whatever visa or permission to enter is required for their circumstances.
The UK government states that visitors must have a passport or travel document that is valid for the whole of their stay.
Nigeria is also among the nationalities listed by the UK government as requiring a visa to enter or transit the UK in the relevant circumstances.
For Nigerians who already hold British passports, however, the personal-detail rules are the more relevant issue.
Anyone who has recently changed their name, gender or appearance should check whether the change means their existing passport needs to be replaced before making international travel arrangements.
Travellers should update their passport before booking
The UK government advises people not to book travel until they have a valid passport.
This is especially important for people whose personal details have changed.
A mismatch between the name on a passport and the name used to book a journey can create difficulties because the government specifically requires the passport name to match the name used for travel bookings.
The safest approach is therefore to check the passport requirements first, update the document where necessary and only then make travel arrangements.
For UK passport holders, the central rule is straightforward: major changes to identity details can require a new passport, while ordinary changes such as moving house, starting a new job or making minor alterations to one’s appearance generally do not.
