Travel Documents in the UK
Following the exit of the United Kingdom from the European Union, the documents required to travel to London have changed over the last few years. Learn what new documents are needed to travel to London.
As of April 2025, visitors must apply for an Electronic Travel Authorisation (ETA) to travel to London. The authorisation is mandatory for EU citizens, as well as for travelers from countries that previously did not require a visa to enter the UK, such as Argentina, Brazil, the United States and Australia.
When planning your trip to London, be sure to apply for the Electronic Travel Authorisation at least 3 days before traveling. To be extra safe, apply for your authorisation before purchasing airline tickets.
Once granted, the authorisation is valid for 2 years and can be reused for various trips to the UK (as long as the same passport is used).
The authorisation to travel to London can only be applied for online via the official app or via the UK Government website. You do not need to print it out, as it's digitally linked to your passport.
The cost of the ETA is £ 16 (US$ 21.30). If the authorisation is refused, the fee will not be refunded.
