(UNITED KINGDOM) — The British government began full enforcement on Wednesday of a requirement that many travellers obtain digital permission before they travel to or transit through the United Kingdom.
Mike Tapp, the UK Minister for Migration and Citizenship, confirmed the “hard start” in a written statement to Parliament (UIN HCWS1361). “Today, 25 February 2026, marks a significant milestone in the transition to a fully digital immigration system with the UK moving to full enforcement of its digital ‘permission to travel’ requirements. Everyone (except British and Irish citizens and some other exempted cohorts) wishing to travel to the UK will need a ‘permission to travel’, and this requirement will be enforced.”
Airlines, ferry operators and international rail providers now check for an approved Electronic Travel Authorisation, known as an ETA, or other digital status before boarding. Travellers without it can find the decision made before they even reach the UK border.
The move ends the transition period from rollout to enforcement, shifting the system from broad awareness-building to tighter compliance at check-in desks, boarding gates and automated travel document checks. Travellers are hearing about the change through carrier emails, online check-in prompts and extra document questions.
Since its phased launch in October 2023, the scheme has granted over 19.6 million ETAs and generated more than £383 million in revenue, which the UK government states is being reinvested into border security and technology. The Home Office described the enforcement step in a late-February update carried on its UK Home Office news.
Carriers have become stricter as enforcement begins because they are legally required to verify a passenger’s digital permission via the Advance Passenger Information (API) system before boarding. The policy is framed by the government as “No Permission, No Travel,” with checks intended to prevent improper travel before passengers arrive.
The new reality affects “non-visa nationals,” meaning citizens who previously travelled visa-free for short stays. Under the ETA system, citizens of 85 countries who previously travelled visa-free now need digital permission before travel, including for transit.
Examples of affected travellers include citizens of the United States, Canada, Australia, and all EU member states. The government describes the ETA as permission to travel, not a visa, and it does not guarantee entry.
For many travellers, the most immediate change comes when they try to board rather than when they land. Airline staff and automated systems typically verify ETA status through the same passenger information flows already used to share passport details ahead of departure.
The U.S. Embassy in London warned Americans about the new boarding and transit risks nearly two weeks ago. “Effective February 25, 2026, all U.S. citizens transiting the UK or traveling to the UK for tourism, family visits, business meetings, conferences, or short-term study for 6 months or less will require an Electronic Travel Authorisation (ETA) prior to travel. If you do not have evidence of an approved ETA before travelling, you may be denied boarding by your airline.”
Transit has become a common friction point as full enforcement starts. In-scope travellers passing through the UK can now find that a digital travel permission is required in practice, including when travel plans involve changing flights.
Another group getting caught out includes dual nationals with British citizenship who try to use the ETA route. British dual citizens, including U.S.-UK citizens, cannot apply for an ETA, and the government guidance points them to using a British passport or a digital Certificate of Entitlement linked to their foreign passport.
Problems often appear at check-in when the traveller’s passport does not match the status the carrier expects to see. In those cases, the consequence is more likely a denial to board than a later fix at the border.
The ETA has a simple consumer-facing pitch, but it comes with tight practical requirements under enforcement. An ETA costs £16 and is valid for two years or until the holder’s passport expires, whichever comes first.
Validity ties directly to the passport used for the application, which means the permission ends when that passport expires even if time remains. The ETA allows multiple entries, with visits of up to 6 months per visit.
Authorities advise travellers to apply at least 3 working days in advance. Decisions are often in minutes, but the government’s recommended lead time has taken on greater weight once carriers began enforcing the boarding check.
In operational terms, enforcement means carriers must verify an ETA or an eVisa before a passenger boards, using passenger data checks tied to the API process. Travellers can experience this as extra online check-in questions, kiosk prompts, or requests for document verification.
The government’s shift to digital status goes beyond the ETA programme. The UK has ended the issuance of physical visa vignettes, and most visa-required nationals now receive an eVisa only, accessible through a UKVI account.
That change can surprise travellers who expect a sticker or paper document in their passport. Under the system described by UK authorities, a traveller may instead need to rely on digital status that carriers and border officials can verify electronically.
The Home Office has pointed travellers and carriers to detailed guidance as enforcement begins, including an ETA factsheet issued earlier this month. The government published the Official ETA Factsheet on Feb. 6, 2026.
The U.S. government has also directed travellers to the embassy’s guidance as the new requirements took effect. The advisory appeared in a Feb. 12, 2026 routine message published by the U.S. Embassy London guidance.
Carrier implementation can vary by route and airport, but the requirement is applied at boarding as well as at the border. For travellers, officials’ message is to verify their status through official channels and keep travel documents aligned to the passport used for the ETA or eVisa.
The government has presented the change as the final step in building a “digitally-default” border, mirroring the U.S. ESTA and the Australian ETA systems. For travellers used to visa-free UK trips, full enforcement means the permission check now happens before wheels up, not after landing.
Non-Visa Nationals Need Electronic Travel Authorisation as Transition Ends
The UK government has officially mandated that all visa-free travelers obtain an Electronic Travel Authorisation (ETA) before arrival. Starting February 2026, carriers are legally required to verify this digital permission at check-in. The policy affects citizens from 85 countries, including the US and EU, even for transit. This shift marks the completion of the UK’s transition to a fully digitalized border and immigration system.
