A Home Office update effective from 25 February 2026 has raised concerns among some British citizens holding dual nationality, according to travel platform VisaHQ. The new regulation mandates that anyone with British citizenship must present a valid British passport or a right to abode certificate alongside their foreign passport when travelling to the United Kingdom. This rule affects airlines, ferry operators and rail companies, who are now required to verify travellers’ documentation before boarding.
Azahara Cochrane de la Rosa, a British-Spanish dual national, told The Guardian on 14 April that she now fears being unable to return home after travelling to Spain with her Spanish passport, which she has used routinely throughout her life. This change comes under the ‘no permission, no travel’ regime, compelling transport companies to refuse boarding to passengers who cannot show the correct documents, under threat of significant fines.
Many airlines have updated their check-in systems to block boarding passes if the details do not match a British passport for dual nationals. Industry sources highlight that the operational change was introduced with limited notice, leaving frontline staff to interpret complex nationality situations at the gate. This has increased confusion during check-in and boarding processes.
Implications for dual nationals and employers
For international travel managers, this regulation serves as a clear reminder that employees with dual nationality must always use their British passport when returning to the UK, even for short business trips within Europe. Where a British passport has expired, individuals are advised to obtain a right to abode certificate, although current processing times range between six to eight weeks.
Operational challenges for companies and transport providers
Employers booking travel using non-British passports for employees risk costly last-minute disruptions. Travel approval workflows and online booking tools must accurately capture dual nationality status and British passport details to ensure compliance. Immigration advisors note that this policy aligns with the UK’s transition towards a fully digital immigration system.
Later this year, transport firms will perform automated Permission to Travel (PTT) checks against the government’s Advanced Passenger Information system before issuing boarding passes. Dual nationals who fail the PTT check will be denied boarding well before the gate. Accordingly, companies are urged to audit traveller profiles now and confirm British passport information is current within their global travel management systems.
