The British passport will become mandatory for entry into the United Kingdom for all British dual citizens starting 25 February 2026. Under updated Home Office travel documentation rules linked to the Electronic Travel Authorisation (ETA) system, dual nationals will no longer be allowed to enter the UK using only a foreign passport.
From the enforcement date, travellers who hold British citizenship must present a valid British passport or a foreign passport containing a Certificate of Entitlement to the Right of Abode. Without one of these documents, airlines may refuse boarding and entry into the UK may be denied.
This change affects millions of dual nationals living in Europe, North America, Australia, and other regions.
Why the British Passport Is Now Required
The UK government is fully implementing its Electronic Travel Authorisation (ETA) system, which requires carriers to verify passenger documentation before departure.
Although British citizens are exempt from applying for an ETA, the system identifies nationality through passport data. A dual citizen travelling on a foreign passport alone will be treated as a non-British national unless they hold proof of their right of abode.
Because of this system update, presenting a British passport becomes the simplest and most reliable way for dual citizens to confirm their status at the border.
Officials have indicated that the rule improves border security, ensures accurate immigration records, and reduces confusion at entry points.
Who Must Carry a British Passport?
The new rule applies to:
- British dual citizens living overseas
- Individuals who hold both British and EU nationality
- British-American, British-Canadian, and British-Australian citizens
- Children born abroad to British parents who qualify as British citizens by descent
- Individuals who have never previously applied for a British passport
Even if someone has never held a British passport before, they may still legally be a British citizen. From 25 February 2026, such individuals must obtain one before travelling to the UK.
Official British Passport Fees and Right of Abode Costs (2026)
British Passport & Entry Documentation Fees
British Adult Passport (Online): £94.50
Child British Passport (5-year validity): £61.50
Certificate of Entitlement to Right of Abode: £589
Estimated Overseas Processing Time: Around 3 weeks (subject to change)
The British passport remains the most cost-effective and practical document for dual citizens compared to the significantly higher £589 fee for a Certificate of Entitlement.
The certificate is physically placed in a foreign passport and confirms the holder’s unrestricted right to live and work in the UK. However, if the foreign passport expires, a new certificate must be purchased.
Can Dual Citizens Travel Without a British Passport?
From 25 February 2026, a foreign passport alone will not be sufficient for entry.
There are only two acceptable options:
- A valid British passport, or
- A foreign passport containing a valid Certificate of Entitlement.
Expired British passports, naturalisation certificates, or other documents are not generally accepted for carrier verification purposes.
Transport providers may face penalties if they carry passengers who do not meet documentation requirements. As a result, airlines are expected to strictly enforce the new rule.
What Dual Citizens Should Do Now
If you hold British citizenship and another nationality, consider the following steps:
- Confirm your citizenship status through official government channels
- Apply for or renew your British passport as early as possible
- Ensure your name matches across all passports and documents
- Avoid booking non-refundable travel until documentation is received
- Keep both passports when travelling internationally
Processing delays can occur during peak seasons, so early preparation is advisable.
Impact on Children Born Abroad
Children born outside the UK to British parents may automatically qualify for British citizenship by descent.
If eligible, they must obtain a British passport before travelling to the UK after 25 February 2026. Parents should verify eligibility and begin the application process well in advance of planned travel.
Failure to do so could result in boarding refusal.
How Long Is a British Passport Valid?
- Adult British passport: 10 years
- Child British passport: 5 years
Renewals can typically be completed online. Applicants must provide identity verification and supporting documents depending on their circumstances.
