From 25 February 2026 carriers can prevent non-visa nationals from travelling without an ETA or other valid digital permission. An ETA costs GBP16, permits multiple journeys, and lasts for two years or until the linked passport expires, whichever is sooner. It is permission to travel, not permission to enter.
Visa-exempt visitors other than exempt categories such as British and Irish citizens.
