UK ETA: The Complete Guide for International Travellers

If you're planning a trip to the UK and you don't need a visa, you've probably heard about the UK ETA. It's a new requirement that's rolling out for travellers from countries like the US, Canada, Australia, and many others.

Think of it as a digital permission slip. You apply before you travel, and if approved, you can board your flight and head to the UK border. It's not a visa — it's faster, cheaper, and simpler.

But it's still mandatory.

This guide covers everything you need to know: who needs one, how to apply, what it costs, and what happens when you arrive. By the end, you'll know exactly what to do.

What is the UK ETA?

The UK ETA (Electronic Travel Authorisation) is a digital pre-travel check for people who can visit the UK without a visa. It's not a visa. It's an authorisation that lets you board a plane or train and present yourself at the UK border.

The system is similar to the US ESTA or Canada's eTA. You apply online, pay a small fee, and get a decision quickly — often within minutes. Once approved, your ETA is electronically linked to your passport.

You don't need to print anything.

The UK government introduced the ETA to strengthen border security and screen travellers before they arrive. It's part of a broader digital transformation of the UK border.

Why the UK introduced the ETA system

The UK ETA is designed to enhance national security by pre-screening travellers. It allows authorities to identify potential risks before departure. This reduces the chance of issues at the border.

The system also streamlines entry for legitimate visitors. By checking travellers in advance, border officers can process arrivals faster. This benefits both tourists and business travellers.

For example, a Canadian tourist flying to London Heathrow can complete the ETA online from home. Upon arrival, their details are already verified, so the border check takes just a few minutes.

How the UK ETA differs from other travel authorisations

While similar to the US ESTA, the UK ETA has unique features. It is valid for two years and allows multiple visits. Each visit can last up to six months, which is longer than some other systems.

The cost is also notably low at £20. This makes it affordable for frequent travellers. For instance, a US businessperson visiting London quarterly can use the same ETA for all trips.

Unlike some systems, the UK ETA does not require biometric appointments. The entire process is online, making it convenient for travellers worldwide.

Who needs a UK ETA?

Not everyone needs an ETA. The requirement depends on your nationality and how you plan to travel. Here's the breakdown.

Nationalities that need an ETA

If you hold a passport from a country that does not need a visa for short visits to the UK, you'll likely need an ETA. This includes:

• United States
• Canada
• Australia
• New Zealand
• Japan
• South Korea
• Singapore
• European Union countries (from 2025)
• And many others.

You can check the full list on the official UK government ETA guidance.

Who does NOT need an ETA?

You do not need an ETA if:

• You hold a UK visa (including a visitor visa, work visa, or student visa).
• You have a British passport or have right of abode in the UK.
• You are a citizen of Ireland (you have a separate agreement).
• You are travelling with a passport from a country that requires a visa for the UK (you must apply for a visa instead).

If you're unsure, use the official government checker or see our detailed guide on who needs a UK ETA.

Special cases for dual nationals

Dual nationals must apply with the passport they intend to travel on. If one nationality requires a visa, you cannot use the other to get an ETA. For example, a person with US and Iranian passports must use the Iranian passport and apply for a visa.

This rule prevents circumvention of visa requirements. Always check both nationalities before applying.

How to apply for a UK ETA

The application process is straightforward. You can do it entirely online or via a mobile app. Here's the step-by-step.

Step 1: Check if you need an ETA

Before you start, confirm that your nationality requires an ETA. If you're a visa national, you need a visa, not an ETA.

Step 2: Gather your documents

You'll need:

• A valid biometric passport (with a chip) from an eligible country.
• A digital passport photo (you can take one with your phone).
• An email address to receive the decision.
• A debit or credit card to pay the fee.

Step 3: Complete the online application

Visit the official UK government website or use the UK ETA app. You'll fill in your personal details, passport information, and answer a few security questions. The form takes about 10 minutes.

Step 4: Pay the fee

The UK ETA costs £20. You can pay by credit or debit card. There are no additional charges.

For more details, see our page on how much does a UK ETA cost.

Step 5: Wait for the decision

Most applications are approved within minutes. In some cases, it may take up to 72 hours. You'll receive an email confirming the result.

Step 6: Travel with your ETA

Once approved, your ETA is linked to your passport. You don't need to print anything. When you check in for your flight or train, the carrier will verify your ETA electronically.

Tips for a smooth application

Ensure your passport is biometric and valid for your entire stay. Double-check all details before submitting to avoid delays. For example, a misspelled name can cause issues.

Apply at least a few days before travel, even though decisions are fast. This gives time to resolve any problems. Keep your application reference number safe for status checks.

UK ETA requirements

To get an ETA, you must meet certain conditions. Here are the key requirements.

• You must hold a valid biometric passport from an eligible country.
• Your passport must be valid for the duration of your stay.
• You must not have a criminal record that would make you inadmissible.
• You must not have previously breached UK immigration rules.
• You must intend to stay for no more than 6 months per visit.
• You must not work in the UK (unless permitted under a separate visa).

For a full list, check the official uk eta application requirements.

Additional conditions for approval

The UK government considers several factors when reviewing applications. These include past travel history and any previous visa refusals. A clean record generally leads to quick approval.

If you have a minor criminal record, you may still be eligible. However, serious offences can lead to refusal. For instance, a US tourist with a DUI conviction might face additional scrutiny.

Always answer all questions truthfully. Providing false information can result in a ban from future travel.

How long does a UK ETA last?

An approved UK ETA is valid for 2 years from the date of issue. During that time, you can make multiple visits to the UK. Each visit can last up to 6 months.

If your passport expires before the ETA, the ETA becomes invalid. You'll need to apply for a new ETA with your new passport.

What happens when your ETA expires?

You must apply for a new ETA if you plan to travel after expiry. There is no grace period. For example, an Australian tourist whose ETA expires in March must reapply before a June trip.

The new application is the same process as the first. You pay the fee again and receive a fresh decision.

What can you do with a UK ETA?

With a valid UK ETA, you can:

• Visit the UK for tourism, holidays, or short courses.
• Visit family and friends.
• Attend business meetings, conferences, or events (but not work).
• Transit through the UK to another country.
• Stay for up to 6 months per visit.

Permitted activities in detail

Tourism covers sightseeing, visiting attractions, and leisure travel. A Japanese couple can explore London's museums and the Scottish Highlands. Short courses include language classes or hobby workshops lasting less than six months.

Business activities include attending meetings, negotiating contracts, or participating in conferences. A Canadian executive can meet with UK partners without needing a work visa. Transit passengers can pass through UK airports to reach other destinations.

What you cannot do with a UK ETA

An ETA does not allow you to:

• Work in the UK (paid or unpaid).
• Study for longer than 6 months.
• Access public funds.
• Settle or live permanently.
• Marry or register a civil partnership.

If you plan to do any of these, you need a visa.

Consequences of violating ETA rules

Overstaying or working without permission can lead to deportation. It may also result in a ban from future UK travel. For instance, a New Zealander who takes a paid job could face serious penalties.

Always check your permitted activities before travelling. If unsure, consult official guidance or legal advice.

UK ETA for transit passengers

If you're transiting through the UK, you may still need an ETA. The rules depend on whether you pass through border control.

If you stay airside (don't pass through immigration) and your flights are connected, you do not need an ETA. But if you leave the transit area or need to clear immigration, you must have an ETA or visa.

Always check with your airline.

Transit scenarios explained

Consider a South Korean traveller flying from Seoul to New York with a layover in London. If they stay in the transit lounge and board the same plane, no ETA is needed. However, if they switch terminals or have an overnight stop, they may need an ETA.

Some airports have specific transit rules. For example, Heathrow's Terminal 5 transit area is straightforward, but other terminals may require immigration clearance. Always verify with your airline or the airport website.

What happens at the UK border?

When you arrive in the UK, you'll go through border control. The Border Force officer will check your passport and ask about your visit. Your ETA status will show up on their screen.

You may still be asked questions about your travel plans, accommodation, and return ticket. Be honest and clear. The officer has the final say on whether to grant you entry.

An ETA does not guarantee entry — it only allows you to travel to the UK. The border officer can refuse entry if they have concerns.

Typical border control questions

Officers may ask about your itinerary, where you are staying, and how long you plan to stay. They might also inquire about your employment or purpose of visit. For example, a US tourist might be asked about hotel bookings and return flights.

Having documents ready, such as hotel confirmations or invitation letters, can help. Answer confidently and truthfully to avoid delays.

Common reasons for UK ETA refusal

Your ETA application can be refused. Common reasons include:

• Criminal record or previous immigration offences.
• Incorrect or incomplete application.
• Passport not biometric or from an eligible country.
• Previous overstay in the UK or elsewhere.

If your ETA is refused, you'll receive a reason. You can reapply if the issue is fixed, or apply for a visa instead.

How to address a refusal

Review the refusal reason carefully. If it's due to an error, correct it and reapply. For example, if you provided the wrong passport number, submit a new application with the correct details.

If the refusal is based on criminal history, you may need to apply for a visa instead. The visa process involves more scrutiny but may still be approved. Seek legal advice if needed.

UK ETA vs visa: what's the difference?

Many travellers confuse ETAs with visas. Here's a quick comparison.

Feature	UK ETA	UK Visitor Visa
Who needs it	Visa-exempt nationals	Visa nationals
Cost	£20	£115 (standard)
Processing time	Minutes to 72 hours	3 weeks (standard)
Validity	2 years	Up to 10 years
Max stay per visit	6 months	6 months
Application	Online, no documents	Online + documents + biometrics

If you're from a visa-exempt country, the ETA is much simpler and cheaper.

When to choose a visa over an ETA

If you plan to work, study long-term, or settle, a visa is necessary. The ETA is only for short visits. For example, a US student attending a year-long course needs a student visa, not an ETA.

Visa nationals must always apply for a visa, even for short trips. The ETA is not available to them.

When does the UK ETA start?

The UK ETA is being rolled out in phases. It started in 2024 for some nationalities (e.g., Qatar, Bahrain, Kuwait, Oman, UAE, Saudi Arabia). From 2025, it will expand to all visa-exempt nationals, including the US, Canada, Australia, and EU countries.

Check the official timeline to see when your country is included.

Phased rollout details

The first phase in 2024 covered Gulf Cooperation Council countries. Travellers from these nations now need an ETA. The second phase in early 2025 includes other visa-exempt countries.

By late 2025, all eligible nationalities should be required to have an ETA. Stay updated through official channels to avoid last-minute surprises.

How to check your UK ETA status

After applying, you'll get an email with the decision. You can also check your ETA status online using your application reference number and passport details.

If you haven't heard back after 72 hours, contact the UK ETA support team.

What to do if you lose your reference number

Your reference number is sent via email. Check your spam folder if you don't see it. If lost, you may need to reapply or contact support with your passport details.

Keep a copy of the confirmation for your records. It can help resolve any issues at check-in.

Can you cancel or change a UK ETA?

Once approved, you cannot change the details on your ETA. If your passport changes or you need to update information, you must apply for a new ETA. The old one becomes invalid.

You can cancel an ETA if you no longer need it, but the fee is not refundable.

What if you lose your passport?

If your passport is lost or stolen, the linked ETA becomes invalid. You must apply for a new ETA with your replacement passport. For example, an Australian tourist who loses their passport in Paris needs a new ETA for their UK trip.

Report the loss immediately to local authorities and your embassy. Then apply for a new ETA once you have the new passport.

UK ETA for dual nationals

If you hold two passports, you must apply with the passport you intend to travel on. If one of your nationalities requires a visa, you cannot use the other nationality to get an ETA.

For example, if you are a US and Iranian dual national, you must apply for a visa using your Iranian passport, because Iran is a visa-required country.

Practical advice for dual nationals

Always carry the passport you used for your ETA when travelling. This avoids confusion at the border. For instance, a Canadian-British dual national must use their Canadian passport for the ETA if they don't hold a UK passport.

Check both nationalities' requirements before booking travel. This ensures you have the correct documentation.

UK ETA for children

Children need their own ETA. Each child must have a separate application linked to their own passport. The fee is the same (£20).

Parents or guardians can apply on their behalf.

Applying for infants and toddlers

Even babies need an ETA if they have their own passport. The application is simple and requires basic details. A parent can complete it in a few minutes.

Ensure the child's passport is biometric and valid. For example, a US family with a 2-year-old must apply for the child's ETA separately.

UK ETA for groups and families

Each person in a group needs their own ETA. There is no group application. You can apply for multiple people one after another online.

Tips for group travel

Start applications early to allow time for any issues. Keep a list of reference numbers for all group members. For instance, a school trip with 20 students needs 20 separate applications.

Double-check that all passports are eligible. This avoids last-minute problems at the airport.

What to do if your UK ETA is delayed

Most applications are processed instantly. If yours is delayed, it may be due to additional checks. Wait at least 72 hours before contacting support.

Make sure you applied at least a few days before your travel.

Possible reasons for delay

Delays can occur if your name matches a watchlist or if additional verification is needed. For example, a common name like John Smith might trigger extra checks.

Providing complete and accurate information reduces delays. If you have a common name, consider applying well in advance.

Can you apply for a UK ETA at the airport?

No. You must apply before you travel. There is no facility to apply at the airport. If you arrive without an ETA, you may be denied boarding.

Consequences of arriving without an ETA

Airlines check for ETA before allowing boarding. Without it, you cannot fly. For instance, a Canadian traveller at Toronto Pearson without an ETA will be refused check-in.

Plan ahead to avoid this situation. Apply online from home or on your phone before heading to the airport.

UK ETA and the EU ETIAS

Don't confuse the UK ETA with the EU's ETIAS system. ETIAS is for travel to Schengen countries, not the UK. The UK is no longer part of the EU.

You'll need both if you visit both areas.

Planning trips that include both UK and EU

If your itinerary includes London and Paris, you need both the UK ETA and the EU ETIAS. Apply for each separately. For example, a US tourist visiting both cities must complete two applications.

Check the requirements for each destination well in advance. This ensures smooth travel across borders.

Frequently asked questions about the UK ETA

Do I need a UK ETA if I have a US passport?

Yes, from 2025, US passport holders will need an ETA to visit the UK for tourism, business, or transit. Apply online before travel.

How long does it take to get a UK ETA?

Most applications are approved within minutes. In some cases, it can take up to 72 hours. Apply at least a few days before your trip.

Can I work in the UK with an ETA?

No. An ETA does not allow you to work. You can attend business meetings and conferences, but you cannot take employment. For work, you need a work visa.

What happens if my UK ETA is refused?

You can reapply if the issue is resolved, or apply for a visitor visa instead. The visa process is longer and more expensive.

Is the UK ETA the same as a visa?

No. An ETA is a pre-travel authorisation for visa-exempt travellers. It's cheaper, faster, and simpler than a visa. But it does not guarantee entry.

Can I use my ETA for multiple entries?

Yes, the ETA allows multiple entries over its two-year validity. Each visit can last up to six months. For example, a New Zealander can visit several times for holidays or business.

Do I need an ETA for a connecting flight?

It depends on whether you pass through border control. If you stay airside, no ETA is needed. If you clear immigration, you need one.

Check with your airline for specific guidance.
