Applications for non-Europeans will open on 27 November, with an ETA needed to travel from 8 January 2025.
ETAs will then extend to eligible Europeans from 5 March 2025, with ETAs needed to travel from 2 April 2025.
The ETA will cost £10 and permit multiple journeys to the UK for stays of up to six months at a time over two years, or until the holder’s passport expires, whichever comes first.
It will be needed by anyone who is not a British or Irish citizen who does not need a visa and must be purchased in advance of travel.
