What Is ETA UK? The UK Electronic Travel Authorisation Fully Explained

Put simply, the UK Electronic Travel Authorisation (ETA) is a new entry requirement for travellers who do not need a visa to visit the UK. It works like a pre-screened permit: you apply online, get a digital decision, and the system links your approval to your passport number. No stamp, no sticker, no document to print.

If you have flown to the United States since 2009, you already know this concept — it is very similar to the American ESTA. The UK has built its own version as part of a broader plan to digitise the border. And it affects far more people than you might expect: travellers from the US, Canada, Australia, New Zealand, Japan, and dozens of other countries now need one for most trips.

This article explains exactly how the system works: who needs it, who is exempt, how to apply, what it costs, and what actually happens at the border when you arrive. If you have a trip to the UK coming up, this is where you get the full picture.

What is a UK ETA?

A UK ETA is an official digital authorisation that allows a traveller to enter the UK for a short stay. It is not a visa. It is a pre-travel check on people who would otherwise not need a visa at all.

The Home Office describes it as a requirement for "non-visa nationals" who want to travel to the UK for tourism, visiting family, short business trips, or study of up to six months. You must apply, pay the fee, and receive approval before you board your flight, ferry, or train.

Here's the key thing: it is linked to your passport number, not a printed document. When you go through border control, officers (or ePassport gates) will see your ETA status automatically when they scan your passport.

ETA vs eVisa vs visa — what is the difference?

This is where travellers often get confused. The UK has three separate digital systems, and they are not interchangeable:

• UK ETA — for visa-exempt nationals who do not need a visa. It is an added security check before travel.
• UK eVisa — a digital record of an actual immigration status, such as a work visa, student visa, or family visa. It replaces the physical biometric residence permit (BRP).
• Standard visitor visa — a traditional permission for visitors from countries that do require a visa (for example, India, Nigeria, or Pakistan). This is not electronic; it remains a sticker in your passport.

If you hold a valid UK visa or an eVisa, you do not need an ETA. Your existing immigration status covers your entry. But if you are a visa-exempt national, the ETA is now mandatory.

Why did the UK introduce the ETA?

The official reason is border security and efficiency. The UK Home Office wants to know exactly who is entering the country before they arrive, mirroring systems used by the US (ESTA), Canada (eTA), and Australia (Australia's ETA, incidentally).

The stated goals are:

• Preventing crime and illegal immigration by screening travellers before they board.
• Reducing overstaying in the visitor category.
• Removing paper queues at the border and speeding up passenger flow.
• Cutting costs associated with processing physical paperwork.

You can also view it as part of the UK's wider shift to a fully digital border. The physical passport stamp is fast becoming obsolete at UK airports. Everything is moving into the system.

From a traveller's perspective, the ETA adds one small step to trip planning. It does take a bit of effort — but it also gives you a confirmed authorisation before you spend money on flights. In theory, that means fewer people get turned away at the border.

Who needs a UK ETA?

The list of nationalities that need the ETA has grown in stages. The UK has rolled it out in phases, and by early 2025, nearly all visa-exempt nationals are included.

You need a UK ETA if all of these apply:

• You hold a passport from a country that does not require a visa for short UK visits.
• You plan to stay in the UK for less than six months.
• You are travelling for tourism, business, study, or to visit family.
• You are not a UK or Irish citizen.
• You do not already hold a valid UK visa, permit, or right of abode.

The requirement now covers passport holders from:

• All EU and EEA countries (including Switzerland) — added on 2 April 2025.
• The United States, Canada, Australia, New Zealand, and Japan.
• South Korea, Singapore, Taiwan, Hong Kong, and many Middle Eastern countries.
• Brazil, Argentina, Mexico, Chile, and several other Latin American nations.

Who is exempt from the ETA requirement?

Not everyone needs one. The following travellers are exempt:

• British and Irish citizens — they have an automatic right to enter the UK.
• Holders of any valid UK visa — including tourist visas, work visas, and student visas. Your visa governs your entry.
• Holders of UK Biometric Residence Permits or eVisas.
• People with right of abode in the UK.
• Passengers who are exempt under the Channel Islands or Isle of Man arrangements in limited circumstances.
• Diplomatic passport holders in certain cases.

There is also a special rule for transit passengers. If you are passing through a UK airport without passing through border control (airside transit), you normally do not need an ETA — but this only applies if your nationality is visa-exempt. If you need to go through border control to change terminals or collect baggage, you will need the ETA.

Dual nationals: which passport do you apply with?

A very common point of confusion arises for dual nationals. The rule here is logical: you apply with the passport you intend to travel on.

Let's use a concrete example. Suppose you hold both a US passport and a UK passport. You do not need an ETA — you can enter the UK using your British passport because you are a British citizen.

The ETA only applies to non-British and non-Irish citizens.

But what if you hold a US passport and an Australian passport? Both countries are visa-exempt, so both would require an ETA. You still apply with the passport you plan to use at the border.

Your ETA is linked to that specific passport number — not to you as a person. This means:

• If you apply for an ETA using your US passport, you must enter the UK with the same US passport.
• If you switch passports after approval, the ETA will not show up — you need to apply again.
• Each passport requires its own ETA, even for the same person.

The same logic applies to EU nationals with a second nationality from a visa-required country. If you enter with your EU passport, you need an ETA. If you enter with your non-visa-exempt passport and no valid visa, you will be refused boarding.

How does the UK ETA work in practice?

The ETA is digital, so there is no physical card or paper certificate. You apply online, your approval is recorded against your passport number, and the border systems pick it up automatically when your passport is scanned.

This integration is what makes the system quick at the airport. You do not need to queue at a special desk or show a separate document. In most cases, eligible travellers can use the ePassport gates, which scan the photo page of your passport and check your ETA status in the background.

The process works for all modes of transport:

• By air — airlines check your ETA status before issuing a boarding pass. If you don't have one, you won't fly.
• By sea — ferry operators carry out the same checks at the port.
• By rail — Eurostar checks ETA status for eligible travellers before boarding in Paris, Brussels, or Amsterdam.

What does the ETA actually allow you to do?

An approved ETA grants you the same permissions as a standard visa-free visit. That means you can:

• Stay in the UK for up to six months at a time.
• Visit friends and family.
• Travelling for tourism or attending events.
• Undertake business activities like meetings, conferences, and negotiations.
• Enrol in a short course of study (up to six months).
• Transit through the UK on your way to another country.

You cannot use an ETA to work in the UK, claim public funds, or live here permanently. It is strictly for short visits.

How to apply for a UK ETA

Applying for a UK ETA is straightforward — most people finish it on their phone in under 15 minutes. There is a dedicated app, or you can use the official GOV.UK website.

Here are the steps:

1. Visit the official UK ETA application page on GOV.UK or download the "UK ETA" mobile app (available on iOS and Android).
2. Scan or photograph your passport's biometric page. The app uses this to read your details automatically — you do not need to type everything manually.
3. Provide your contact email address and a phone number.
4. Answer a set of security and eligibility questions. These are similar to ESTA questions: criminal history, immigration history, and any past security concerns.
5. Pay the £20 fee using a credit or debit card.
6. Submit the application and wait for the decision.

Most applications (around 85–90%) are approved within minutes. Others can take up to three working days for additional checks. For the full list of documents and eligibility conditions, see our page on uk eta application requirements — the form asks for very little, but knowing the exact rules before you start saves time.

How much does a UK ETA cost?

As of 2025, the UK ETA fee is £20 per person. This covers every member of your family, including infants — each traveller needs their own ETA linked to their own passport.

For the most up-to-date fee and payment details, you can check our breakdown of how much does a uk eta cost. The fee is payable online by card, and there are no processing fees or rush fees — the price is the same whether your application decides in seconds or takes three days.

Note that the ETA is non-refundable. If your travel plans change, you still pay the fee. But because it lasts two years, it is likely to cover multiple trips anyway.

How long is the UK ETA valid for?

An approved ETA is valid for two years from the date of approval, or until your passport expires — whichever comes first.

This is a key detail. If your passport expires in six months, your ETA expires alongside it. You will need a new ETA when you renew your passport, because the ETA is digitally linked to the unique passport number.

For example:

• You apply on 1 June 2025 and your passport expires in June 2027.
• Your ETA is valid until June 2027 (when the passport expires), not June 2027 for the ETA itself — actually, both dates align at passport expiry.
• If your passport is valid for another five years, your ETA lasts the full two years before you need to renew.

Each approved ETA allows you to make multiple visits during its validity period. There is no cap on the number of trips.

Applying on the official app: what you need

If you decide to use the official UK ETA app (which is the smoothest route), you should prepare the following:

• Your passport — it must be a biometric passport with a chip (the gold camera symbol on the cover).
• Your phone with an internet connection.
• An email address you can access immediately — you will need to verify it.
• A credit or debit card for the £20 fee.

The app uses the NFC chip in your passport to read your details. This makes the application more accurate and reduces the risk of a mismatch at the border. Place your passport on a flat surface, then rest your phone on top of it until the scan completes.

You should also take a live photograph of your face during the process. This is not stored as a visa photo — it is used for your record and matched against your passport photo. Make sure the room is well lit and you are not wearing a hat or sunglasses.

How long does the UK ETA take to approve?

There is no guaranteed processing time, but there is a firm guideline. According to GOV.UK, most applications get a decision within minutes. If your application needs more checks, you should receive a decision within three working days.

That said, you should never apply at the last minute. The three-working-day window is a maximum target, not a guarantee. If your case triggers a manual review, it could take longer.

Here is a realistic timeline:

Because of that uncertainty, the official advice is to apply well before you book travel. Apply as soon as you know you are going — ideally at least three to five days before departure, or even earlier if you have a complex immigration history.

How do you check your ETA status?

You will receive an email confirming the outcome of your application. The email will state whether you are approved or refused. There is no paperwork to carry — all decisions are recorded digitally.

If you applied via the app, you can also check your application status there. It will show "Approved," "Pending," or "Refused." If you lose your approval email, it does not matter — the border system holds the record.

What happens at the border with an ETA?

For most travellers, arriving with an ETA is surprisingly simple. You land, walk to the ePassport gates, scan your passport, and walk through. The system checks your ETA, your security record, and your passport validity in seconds.

If you are not eligible for ePassport gates (for example, you are under 10 or over the age limit set by the gate), you join the standard border officer queue. The officer will scan your passport and see your ETA status on screen.

You may be asked questions about your trip — where you are staying, how long you are visiting, and whether you have a return ticket. That is standard practice and has nothing to do with the ETA itself. Border Force retains the right to refuse entry even to ETA holders.

The ETA is a travel authorisation, not a guarantee of entry.

Your ETA is not checked on departure. You simply leave — the approval sits unused until your next trip within the two-year validity window.

What can go wrong at the border?

Most problems stem from applying with the wrong passport or not applying at all:

• No ETA: Airlines check this at check-in and will refuse to board you.
• Wrong passport used: If you applied with one passport but present another at the border, the ETA will not show.
• Expired ETA: Your passport or two-year validity has lapsed.
• Refused ETA: You cannot travel until the issue is resolved.

Border officers can also refuse entry if they suspect you plan to work illegally, you have no funds for your stay, or you give false information during the ETA application. Answer every question accurately.

ETA and children: do minors need one?

Yes. Every traveller needs their own UK ETA, including babies and children. There is no family application and no family discount.

A parent or guardian can apply on behalf of a child. The process is the same, but you should use the child's passport details and make sure you take a clear photo of the child's face when prompted. Children arriving with an ETA typically use the standard border officer queue because ePassport gates have age restrictions.

Plan the paperwork carefully if you are travelling as a family. A family of four needs four separate ETAs, each costing £20, and each linked to the correct passport.

Technical details: what the system actually does

The UK ETA is part of the Electronic Travel Authorisation (ETA) scheme run by UK Visas and Immigration (UKVI) and Border Force. The system cross-references applicant details against UK and international security databases before issuing approval.

Each application triggers automated checks against watchlists and immigration records. If you have past UK visa refusals, criminal convictions, or security concerns, your application may be refused. If approval is refused, the refusal notification explains the reason and whether you can re-apply.

You cannot appeal an ETA refusal. If you still want to travel, you must apply for a Standard Visitor Visa instead — which is a full visa application, with a fee of £115 (for 6 months), and it may be more complicated. People with a refused ETA are sometimes better off applying for a Standard Visitor Visa, as it offers a more detailed review process.

EU nationals and the April 2025 expansion

If you hold an EU, EEA, or Swiss passport, your situation changed on 2 April 2025. From that date, you need a UK ETA for any short trip to the UK — a direct result of the UK no longer treating EU nationals as having special rights post-Brexit.

This means a French family visiting London for the weekend, a German student attending a summer course, or a Dutch consultant flying to Birmingham for meetings must all apply beforehand. The old visa-free entry as-of-right is gone. The entry conditions are now identical to those for any other visa-exempt nationality.

For EU nationals with settled status in the UK, the rules are different. If you hold a UK eVisa or a Biometric Residence Permit, you use that document — not an ETA — when you travel.

UK ETA for transit passengers

Transit rules confuse a lot of travellers, so let's be precise.

If you are flying from, say, New York to Sydney with a connection at Heathrow, and you stay airside (you do not pass through UK border control), you may not need an ETA. UK transit rules allow visa-exempt nationals to change planes without an ETA as long as they do not enter the UK.

But many travellers do pass through border control:

• You change terminals at some airports and must exit and re-enter.
• You need to collect checked luggage and re-check it.
• You book two separate flights that are not connected through the same ticket.

In any of these cases, you are legally entering the UK, and an ETA is mandatory. Airlines will check this before boarding your first flight. If in doubt, apply for the ETA — it is cheaper than missing your connecting flight.

Are there any plans to change the ETA system?

The UK ETA scheme is relatively new, and the government has already expanded it in stages. The current fee is £20, but the UK government announced in January 2025 that it intends to raise the fee to £16 later in the year. That increase is not yet in force as of the time of writing, but it is worth keeping an eye on official announcements before you pay.

There is also the planned introduction of the UK's Electronic Travel Authorisation for the rest of the world. The scheme was opened to EU and non-EU countries gradually, and by mid-2025, it covers virtually all visa-exempt travellers. No further major expansions are expected.

That means the user experience will stabilise: the app, the fee, and the process will become a standard part of travelling to the UK, the same way ESTA is for the US.

Common mistakes to avoid when applying

People trip up on small details — not because the process is hard, but because they rush. Here are the most common mistakes we see:

• Typing passport numbers manually instead of scanning. Manual entry invites typos. Use the scan function.
• Applying with an old or expiring passport. If your passport is close to expiry, wait until you have the new one.
• Not checking the passport you linked. You must present the exact same passport at the border.
• Submitting without answering travel history honestly. Refusals for dishonesty are harder to overcome than refusals for a criminal record.
• Waiting until 24 hours before departure. Most applications are instant, but yours might not be.

The ETA application is not complicated, but it is mandatory. It is a quick, cheap step that protects your trip from delay — or worse, being stopped at check-in.

Official guidance and the importance of verifying

Rules around the UK ETA change, and the dates matter. Before you travel, always check the latest official requirements on the UK government's website. The Home Office publishes the definitive guidance, including the full list of eligible nationalities and the current fee.

You can find it at the official UK ETA guidance on GOV.UK.

This article is general information to help you understand the scheme — it is not professional immigration advice. If you have a complex immigration history, or if you are not sure whether you qualify for an exemption, you should speak to a qualified immigration advisor or contact UKVI directly.

The good news is that for the vast majority of travellers, the ETA is a once-every-two-years formality. You apply, you get approved, and you travel freely. It takes less time than the security queue at the airport, and it removes the uncertainty of arriving without permission.

This article is for general information only and is not a substitute for official advice. Always verify current requirements with official sources before you travel.

Key takeaways

Here is what you need to remember:

• The UK ETA is mandatory for most visa-exempt nationals, including EU, US, Canadian, Australian, and Japanese passport holders.
• It costs £20 and covers stays of up to six months over two years.
• Apply through the official app or GOV.UK — not third-party sites that charge inflated fees.
• It is digital — no stamps, no printouts, just a passport check at the border.
• Apply early — at least three to five days before departure, not the night before.
• Children need one too, and each passport needs its own ETA.
• Transit through the UK needs careful thought — airside transit is exempt, but passing through border control requires an ETA.

The UK ETA is here to stay. Understanding it now means you will never be caught out at check-in, and your arrival in the UK will be as smooth as the two-year validity of your permit. Apply once, and you're good for multiple trips.
