International travel to the United Kingdom is entering a new phase as the government introduces stricter entry requirements for many visitors. Starting 25 February, travellers from countries that do not require a visa must obtain an Electronic Travel Authorisation (ETA) before flying to the UK.
Under the updated policy, passengers who arrive at the airport without a valid ETA, eVisa, or another accepted travel document will not be allowed to board their flight. Airlines are now required to verify this authorization before departure.
This new requirement is part of the UK government’s wider effort to strengthen border control and transition toward a fully digital immigration system.
Understanding the UK Electronic Travel Authorisation
The Electronic Travel Authorisation (ETA) is a digital travel permit that grants permission to visit the United Kingdom for short stays. It applies to travellers from 85 visa-exempt countries, including the United States, Canada, and several European nations such as France.
Key features of the ETA
-
Application fee: £16 per person
-
Valid for multiple visits
-
Validity period: two years or until the passport expires
-
Linked electronically to the traveller’s passport
Travellers who are required to have an ETA but fail to obtain one before departure will be prevented from boarding their flight to the UK.
Who Must Apply for an ETA?
Citizens of 85 countries who normally travel to the UK without a visa must now apply for an ETA before entering the country.
This requirement applies to travellers visiting for:
-
Tourism
-
Business meetings
-
Short stays
-
Transit through the UK when passing through passport control
Who is exempt?
Some travellers do not need to apply for an ETA, including:
-
British citizens
-
Irish citizens
These individuals must travel with appropriate documents such as:
-
A valid British passport, or
-
A Certificate of Entitlement
Beginning 26 February, Certificates of Entitlement will be issued digitally rather than as physical documents. The digital version will remain valid even if a passport expires.
Similar Systems Around the World
The UK’s ETA system follows a model already used by several countries to pre-screen travellers before arrival.
For example:
-
The United States ESTA costs about $40
-
The European Union’s ETIAS, expected to launch soon, is expected to cost €20
Like these systems, the UK ETA aims to improve security by allowing authorities to review traveller information before they arrive at the border.
How to Apply for a UK ETA
Applying for an ETA is designed to be simple and can be completed online using the UK ETA mobile application.
Applicants will need to:
-
Provide personal and passport details
-
Submit biometric information
-
Answer a few background questions related to criminal history and travel eligibility
Once approved, the ETA is digitally connected to the traveller’s passport, meaning no physical document is required.
Processing times
Most applications are processed automatically within minutes. However, travellers are advised to submit their application at least three working days before their departure, as some applications may require additional review.
Since the program was introduced in October 2023, more than 19 million travellers have successfully applied for an ETA.
Financial Impact and Border Investments
The ETA program has already generated significant revenue. By January 2026, it had brought in more than £383 million.
According to the UK government, this funding is being used to improve border infrastructure and immigration systems.
Migration and Citizenship Minister Mike Tapp has stated that the program is an important step toward modernizing border control while ensuring the country remains secure.
The UK’s Shift Toward Digital Immigration
The ETA is only one part of the UK’s wider move toward a fully digital immigration system.
So far, the government has issued more than 10 million eVisas, replacing traditional physical immigration documents.
Travellers who already hold an eVisa, including individuals under the EU Settlement Scheme, must keep their UK Visas and Immigration (UKVI) account updated with their current passport information.
Failing to update these details may cause delays or difficulties when entering the UK.
Goals of the digital system
-
Reduce reliance on physical paperwork
-
Improve border security and identity checks
-
Speed up the entry process for legitimate travellers
-
Simplify travel documentation

Anyone planning a trip to the UK should confirm whether their nationality requires an ETA and submit their application before booking travel or arriving at the airport.
