The new ETA, the Electronic Travel Authorisation established by the Governement of Great Britain to travel to the UK, a digital permission similar to a visa waiver, allowing visitor to travel for tourism, family, visits, business or short - term study will be mandatory from 2nd April 2025 with an expected cost of €19.0.
From this date, EU, EEA and Swiss citizens, excluding Irish citizens will need an ETA to travel to the United Kingdom for short stays, with applications already openned on 5th March 2025 and it will be mandatory for all travellers, including minors,with the exception of travellers in transit without clearing board control, residents and students with visas, among other situations considered exceptions and although the initial cost was of £10.0 about €12.0, it is expected to rise to £16.0 about €19.0.
The request for authorisation is made through a specific application created by the British Government such as UK ETA app or on the GOV.UK website, and it is recommended to do so at least three days before the planned date of travel, as this is the time it may take to be issued.
Applications, if accepted will mean that the applicant will receive a confirmation email and the document will be digitally associated with their passport.
An ElectrronicTravel Authorisation is valid for two years from the date of grant or until the passaport used in the application expires, whichever is sooner and permits multiple journeys to the UK for stays of up to six month.
