ETA: The New Authorisation to Travel to the UK

20 March 2025

Starting 2 April 2025, all foreign nationals, including EU citizens, will be required to obtain an Electronic Travel Authorisation (ETA) to enter the United Kingdom. This digital travel permit will be mandatory for those visiting England, Scotland, Wales, or Northern Ireland for short stays without a visa or UK immigration status. Portuguese citizens and residents are among those subject to this new requirement.


The ETA functions similarly to ETIAS (Europe’s Travel Authorisation System), which will soon be required for visa-exempt travellers entering certain EU countries. However, it is essential to note that not all EU member states will adopt ETIAS – only 30 countries will implement this system.


While the ETA is a travel permit and not a visa, it does not guarantee entry into the UK. It simply allows the holder to travel to the UK; for the purpose of residing there, a visa is still required.


This system aims to strengthen border security and modernise the UK's immigration process by implementing a more digital and efficient entry system. By requiring travellers to provide biographic, biometric, and contact information, along with responses to a short set of security questions, the ETA helps authorities assess applicants in advance. This not only prevents the entry of individuals who may pose a risk but also ensures a faster and more secure entry process for the millions of travellers who enter the UK each year.


The current cost is 10 pounds, allowing multiple journeys to the UK for stays of up to six months at a time, valid for two years or until the holder’s passport expires – whichever comes first. The UK government has already expressed its intention to increase the cost of an ETA to 16 pounds in the future, justifying the raise as a way to reduce reliance on taxpayer funding for the migration and borders system.


To apply for an ETA, the holder needs to meet certain requirements, which include:


  • Pay the fee.
  • Provide passport and contact details.
  • Submit a valid photo.
  • Answer a set of security questions.



The application process is straightforward and fully online, often taking only a few minutes. However, applicants are advised to apply at least three working days in advance, as additional processing may be required in some cases.


If an ETA application is rejected, authorities will provide a reason, and the applicant may reapply. If the ETA is ultimately refused, the only alternative for travel to the UK would be to apply for a visa.
