The UK’s Electronic Travel Authorisation (ETA) system has officially expanded to European travellers.

Starting 2 April 2025, all European visitors will need ETA approval – or, for some non-EU nationals, a visa – to enter the UK.

The system became mandatory for travellers from the US, Canada and Australia on 8 January 2025, following its rollout last November for nationals of Bahrain, Jordan, Kuwait, Oman, Qatar, Saudi Arabia and the UAE.

Applications for European travellers open today.

Read on for details on cost, validity and how to get it.

What is the ETA?

The ETA replaces the single-use Electronic Visa Waiver (EVW) scheme, offering a lower cost option with multi-entry validity.

The UK government notes that it is not a visa and does not permit entry into the UK. Rather, it authorises a person to travel to the UK.

The ETA is now required for all eligible nationalities. You can find the full list of countries here.

How do I apply for an ETA to enter the UK?

Most visitors will be able to apply using a mobile app and can expect a decision emailed within three days.

Everyone travelling needs to apply, including babies and children, but you can apply for other people.

The UK government says its app is the quickest and easiest way to apply for an ETA. You can download the ETA app from the UK government website.

If you cannot download the app, you can also apply online here.

To complete the application, make sure you have on hand the passport you’ll be travelling on, an email address and a credit card, debit card, Apple Pay or Google Pay. You will have to answer a set of suitability questions. You don’t need to enter your travel details.

You can delete the app when you’ve finished applying. Your ETA will be linked to your passport digitally, and you will not need to show anything else when you enter the UK.

When to apply for your ETA

The government says: “You must apply for an ETA before you travel to the UK. You can travel to the UK while waiting for a decision.”

Considering most applicants will get a decision within three days, it can be assumed you should apply at least three ahead of travelling to the UK, though you can do it much further in advance.

How much does the UK ETA cost?

Like the Electronic System for Travel Authorisation (ESTA) in the US, a fee is attached to the application process. The ETA costs £10, approximately €12 at the time of writing.

According to the British Home Office website, however, the UK “[intends] to increase the cost of an ETA to £16 (€129) in the future.”

How long is the ETA valid?

An ETA lasts for two years. You do not need to apply again during this time.

You can travel to the UK as many times as you want during the period of validity, but you cannot stay for longer than six months on one trip. Check the UK government website for more details on what you can and cannot do on an ETA.

Note that you will need to apply for a new ETA if you get a new passport, as your ETA is linked to it.

Will I need a visa to enter the UK?

As mentioned above, the ETA isn’t a visa, but it does grant permission to enter the country.

All visitors who don’t require a visa currently will need to get an ETA before they travel. This includes those who do not currently need to submit any form of application to visit the UK. US, Canadian, Australian and European citizens need an ETA even for short stays or transiting through the UK, for example.

Travellers from countries that don’t have visa-free entry agreements with the UK will still have to apply for the correct visa and an ETA.

If you don’t apply before your trip, the government says you could be fined, though no further details have been given about this.

You still need to apply if you are transiting through the UK – even if you aren’t going through border control.

The ETA allows you to come to the UK for six months for tourism, visits to family and friends, business or short term study.

You can also get an ETA instead of a visa if you are coming to the UK for up to three months on the Creative Worker visa concession or coming to the UK for a permitted paid engagement. Outside of these conditions, you can’t use an ETA to do paid or unpaid work for a UK company or as a self-employed person.

Who does not need an ETA?

British and Irish citizens, people who already have a visa or permission to live, work or study in the UK, those travelling with a British overseas territories citizen passport and people who live in Ireland and are travelling from Ireland, Guernsey, Jersey or the Isle of Man don’t need to apply for an ETA.

Why is the UK introducing the ETA scheme?

The ETA is part of the UK’s plan to digitise its borders at UK airports by the end of 2025.

The scheme is intended to reduce queues at the border, “helping to speed up legitimate journeys to the UK”.

Facial recognition technology could be used to make these “contactless corridors” possible, British newspaper The Times reports. It would require international travellers to submit biographic and biometric details, like photos of their facesthrough the new Electronic Travel Authorisation (ETA) scheme before they fly.
