Planning a trip to the United Kingdom in 2026 means understanding the new Electronic Travel Authorization (ETA) system. Visitors from countries that don't require visas, such as Australian states, European Union nations, Canada and Japan, are now required to have this digital travel permission. If you are traveling to the country for tourism or business, or for a short-term study course, it's important to have an approved ETA prior to departure. Some of the essentials you should know before you go. 

Which Countries Need a UK ETA?

The  UK ETA  applies to citizens of approximately 85 countries who previously could visit the UK without a visa for short stays. Here are the key points:

• Visa-exempt countries: Citizens from the United States, Canada, Australia, New Zealand, Japan, South Korea, Singapore, Malaysia, and all European Union member states need a UK ETA.



• Additional eligible regions: Passport holders from Hong Kong, Macaw, and Taiwan may also apply.



• Exempt travelers: British and Irish citizens do not need an ETA, and those with a valid UK visa or immigration status are also exempt.



• Transit rule: If you transit through a UK airport without passing through border control, you generally do not need an ETA.

What Documents Are Required for a UK ETA?

Applying for a UK ETA requires just a few essential items. Here are the key points:

1. Passport Bio Page:You must provide a clear photo or scan of your passport's biographical page, which contains your personal details and photograph. Here are the key points:

Can You Travel to the UK Without an ETA?

No, from 25 February 2026, the majority of visa-exempt foreign nationals will not be able to enter the UK without an approved Electronic Travel Authorization (ETA) or a valid visa this will now be strictly enforced at check-in by carriers. British and Irish citizens do not require an ETA and those who already have a valid UK visa or immigration permission (e.g. settled or per-settled status) also do not need an ETA, nor do those who are simply transiting through the air side without entering border controls. Dual British citizens are required to travel with a valid British passport or a Certificate of Entitlement and will not be given an ETA, since they have the right of abode. Airlines, ferry operators and Euro star will not allow someone to get on the train unless they have the right digital permission—even for short visits or stopovers.

What Should You Carry When Travelling With a UK ETA?

• Accommodation details: Keep proof of your accommodation during your stay.



• Proof of funds: Carry evidence of sufficient funds for your trip.
