The UK Home Office has issued a final warning: starting February 25, 2026, the Electronic Travel Authorisation (ETA) requirement will be enforced without any discretion for all eligible non-visa nationals. From that date onward, anyone who needs an ETA to travel to the United Kingdom will be refused boarding by airlines, ferry operators, or Eurostar if they do not have a valid, approved ETA linked to their passport.
This marks the end of any transitional leniency and the full activation of one of the biggest changes to UK border entry since the end of free movement with the EU.
Critical Rule for Dual British/Irish Citizens
Dual nationals holding both British/Irish citizenship cannot travel to the UK using their non-British/non-Irish passport after February 25, 2026. To prove exemption from the ETA scheme, they must present:
A valid British passport, or
A Certificate of Entitlement to the right of abode, or
Proof of Irish citizenship (Irish passport or equivalent)
If your British or Irish passport is expired or lost, renew it now — there will be no exceptions for dual nationals arriving without proof of citizenship. Airlines and carriers have already updated their systems to check ETA status in real time via the Carrier Check API.
ETA Requirements: Who Must Apply & Consequences of Not Having One
The ETA is mandatory for visa-exempt nationals from over 90 countries (including the US, Canada, Australia, Japan, South Korea, UAE, Singapore, and many others) for short visits, tourism, business, or transit.
No ETA = automatic refusal of boarding — no exceptions, no discretion at the gate.
Processing time: Usually minutes, but can take up to 3 working days in complex cases.
Cost: £10 (valid for 2 years or until passport expires, whichever is sooner).
No right of appeal — refused ETAs require a new application or a full visa.
This strict enforcement is part of the UK’s broader digital border transformation, replacing paper vignettes and physical stamps with a fully online system that improves security, tracks arrivals, and reduces fraud.
Practical Advice for Travellers & Employers
Apply early — Submit your ETA application at least 72 hours before travel to avoid last-minute issues.
Dual nationals — Carry your British or Irish passport for UK entry; non-British/non-Irish passports alone will trigger ETA checks and likely refusal.
Employers & global mobility teams — Update travel policies, audit employee passports, and remind staff to renew expired British/Irish documents well before February 25, 2026.
Monitor validity — ETAs are linked to your passport — renew your passport and re-apply for a new ETA if needed.
The February 25 deadline is non-negotiable — plan ahead to avoid being turned away at the airport.
