What Is the UK ETA? A Simple Guide for First-Time Applicants

The UK ETA is a new digital travel authorisation system for visitors who do not currently need a visa to enter the United Kingdom. Think of it as a UK version of the US ESTA or the upcoming EU ETIAS. It's designed to pre-screen travellers before they travel, making entry at the border faster and more secure.

Starting in 2025, the UK ETA will be mandatory for most non-visa nationals – including travellers from the US, Canada, Australia, New Zealand, Japan, and many other countries. If you're one of those travellers, you'll need to get an ETA before you fly, even if you're just transiting through a UK airport.

This guide covers everything you need to know: who needs it, how to apply, costs, validity, and what happens at the border. We'll keep it clear and practical – no fluff.

What exactly is the UK ETA?

The UK ETA is an Electronic Travel Authorisation. It's not a visa. It's a digital permission to travel to the UK for short visits, granted before you travel.

You apply online, and if approved, it's linked to your passport electronically. When you check in for your flight or ferry, the carrier will check that you have a valid ETA.

The system is run by the UK Home Office. It's part of the UK's plan to digitise its borders and know who is arriving before they land. The ETA is designed for tourism, business visits, short-term study, and transit.

You cannot work or live in the UK on an ETA.

How the UK ETA works in practice

When you apply, the system checks your details against security databases. For example, if you have a minor criminal record from years ago, the system may flag this for review. Most applicants receive approval within minutes, but some cases take up to 72 hours.

The ETA is not a physical document. It exists only as a digital record linked to your passport number. When you board your flight, the airline's system automatically verifies your ETA status.

If you don't have one, you may be denied boarding.

Who needs a UK ETA?

If you hold a passport from a country that currently does not need a visa for short visits to the UK, you will likely need an ETA from 2025. This includes citizens of the United States, Canada, Australia, New Zealand, Japan, South Korea, Singapore, Israel, and many European countries (except Ireland).

You do NOT need an ETA if you:

• Hold a UK visa (including a visit visa, work visa, or student visa).
• Hold a British passport (including British Overseas Territories citizens).
• Hold Irish citizenship or have the right of abode in the UK.
• Are a resident of Ireland travelling from Ireland (you may use the Common Travel Area).
• Are a visa national – you already need a visa to visit the UK.

Check the official list of countries that will need an ETA – it's being phased in, so some nationalities may be added later.

For a full breakdown of who is required to apply, see our detailed guide on who needs a UK ETA.

Country-specific examples of ETA requirements

Consider a traveller from Brazil. Brazil is a visa-waiver country for the UK, so Brazilian passport holders will need an ETA from 2025. In contrast, a traveller from India is a visa national and must apply for a standard visit visa instead.

Another example: a Canadian citizen flying to London for a weekend trip will need an ETA. But a Canadian who also holds an Irish passport can use that passport to enter the UK without an ETA, thanks to the Common Travel Area agreement.

How does the UK ETA differ from a visa?

This is a common confusion. The ETA is not a visa. Here's the difference:

If you hold a passport from a visa-waiver country, you use the ETA. If your country is not on the waiver list, you need a visa. Simple.

Why the distinction matters for your travel plans

The ETA is much faster and cheaper than a visa. For example, a family of four from Australia applying for ETAs would pay £80 total and get approval in minutes. The same family applying for visit visas would pay £460 and wait weeks.

However, the ETA offers less flexibility. If you plan to work or study long-term, you need a visa. The ETA is strictly for short visits, tourism, and business meetings.

Always check your specific purpose of travel before applying.

When will the UK ETA be required?

The UK ETA is being rolled out in phases. Here's the timeline as of 2025:

• 2023 (pilot): ETA introduced for Qatari nationals.
• 2024: Expanded to nationals of Bahrain, Kuwait, Oman, UAE, Saudi Arabia, and Jordan.
• 2025: Expected to open to all other visa-free nationals, including US, Canada, Australia, EU citizens, etc. Exact date to be confirmed.

Check the official UK government website for the latest updates. The system is being phased, so your country may not be included yet. Once it is, you must have an ETA before travel.

What to do if your country is not yet included

If your nationality is not on the current ETA list, you do not need to apply yet. Continue travelling as usual under existing visa-waiver rules. However, you should monitor the official announcements for when your country is added.

For example, a Japanese traveller in early 2025 may not yet need an ETA if the rollout for Japan is scheduled for later that year. Once the system goes live for Japan, all travellers must have an ETA before boarding.

How to apply for a UK ETA: step by step

Applying is straightforward. You do it entirely online – no need to visit a consulate or embassy. Here's how:

1. Go to the official UK ETA website (gov.uk). Do not use third-party sites – they may charge extra fees.
2. Complete the application form. You'll need your passport, a valid email address, and a debit/credit card. The form asks for personal details, passport info, and a few security questions.
3. Pay the fee. The UK ETA costs £20 per applicant. That includes all fees – no hidden charges.
4. Submit and wait. Most applications are processed within minutes, but allow up to 72 hours. You'll receive an email confirming approval.
5. Check your passport. The ETA is linked electronically – you don't need a sticker or printout. But it's wise to keep a copy of the approval email.

For a complete checklist of what you need, see our UK ETA application requirements guide.

What information do you need to provide?

The application is simple. You'll need:

• Your full name, date of birth, nationality.
• Passport details (number, issue and expiry dates).
• Email address and phone number.
• Employment details (optional but recommended).
• Travel history to certain countries (e.g., previous visits to the UK, criminal record declarations).
• Payment card details.

No biometrics are required. No interview. No uploading documents.

Common mistakes to avoid during the application

One frequent error is entering passport details incorrectly. For example, mixing up the letter "O" with the number "0" can cause delays. Double-check every field before submitting.

Another mistake is using a third-party website that charges extra fees. Always use the official gov.uk site to pay only £20. Some unofficial sites charge £50 or more for the same service.

How much does a UK ETA cost?

The UK ETA costs £20 per person. That's it. No additional fees for processing or issuance.

You pay online by debit or credit card.

For comparison, the US ESTA costs $21 (about £17), and the upcoming EU ETIAS is expected to cost €20. So the UK ETA is very competitively priced.

Note: If you use a third-party website, you may be charged extra service fees. Always use the official government site to avoid overpaying.

For more details on fees and possible changes, see our article on how much does a UK ETA cost.

Are there any discounts or waivers for the fee?

Currently, there are no discounts for children, students, or senior citizens. Every applicant pays the same £20 fee. However, the UK government may introduce changes in the future, so check the official site for updates.

If you are travelling as a group, each person must pay individually. There is no family discount. For example, a family of five would pay £100 total.

How long is the UK ETA valid for?

Once approved, your UK ETA is valid for 2 years from the date of issue, or until your passport expires – whichever comes first. So if your passport is due to expire in 18 months, your ETA will only be valid for that 18 months.

During its validity, you can make multiple trips to the UK. Each visit can last up to 6 months. You can also use it for transit – for example, if you're flying from New York to Dubai via London Heathrow, you need an ETA even if you don't leave the airport.

If you get a new passport, you'll need to apply for a new ETA – it's not transferable.

What happens if your ETA expires while you are in the UK?

If your ETA expires during your stay, you are not automatically required to leave immediately. You can remain until the end of your permitted 6-month visit. However, you cannot use the expired ETA for future trips.

For example, if you enter the UK on 1 January with an ETA that expires on 15 January, you can still stay until 30 June (6 months from entry). But for your next trip, you must apply for a new ETA.

What can you do with a UK ETA?

The UK ETA allows you to:

• Visit the UK for tourism, holidays, or sightseeing.
• Visit friends and family.
• Attend business meetings, conferences, or events (but not work).
• Take short-term study courses (up to 6 months).
• Transit through a UK airport to another country.
• Perform certain permitted paid engagements (like giving a lecture or performing as an artist) – but check the rules.

You cannot:

• Work for a UK employer (unless you have a work visa).
• Live in the UK long-term.
• Access public funds (benefits).
• Marry or register a civil partnership (you need a marriage visitor visa).

If you're unsure whether your activity is allowed, check the official guidance or consult a qualified immigration adviser.

Examples of permitted activities with an ETA

Consider an American journalist attending a conference in London. They can use an ETA because they are not working for a UK employer. However, if they are paid by a UK company to write articles, they may need a visa.

Another example: a Canadian musician performing at a single concert can use an ETA if the performance is considered a permitted paid engagement. But a tour with multiple paid shows may require a work visa.

What happens at the UK border with an ETA?

When you arrive in the UK, you'll go through border control as usual. The Border Force officer will check your passport and confirm your ETA is valid. You may be asked questions about your visit – purpose, accommodation, return ticket.

Be honest and have your details ready.

The ETA does not guarantee entry – the final decision is always made by the Border Force officer. They can refuse entry if they believe you're not a genuine visitor, or if you pose a security risk. But if you have a valid ETA and meet the visitor requirements, entry should be straightforward.

You'll use the e-gates (if available) or the standard passport queue. E-gates are available for many nationalities – they scan your passport and check your ETA automatically.

What to do if you are stopped at the border

If a Border Force officer questions you, stay calm and provide clear answers. Have your hotel booking, return flight details, and proof of funds ready. For example, if you are visiting for tourism, show your itinerary and accommodation confirmation.

If you are refused entry, you have the right to ask why. You may also request to speak with a supervisor. However, the officer's decision is final at the border.

You can challenge it later through legal channels.

Can your UK ETA be refused or cancelled?

Yes. The Home Office can refuse an ETA application if you have a criminal record, pose a security risk, or have previously breached UK immigration laws. They can also cancel an existing ETA if new information comes to light.

If your ETA is refused, you may still be able to apply for a visit visa instead – but that's a longer and more expensive process. You cannot appeal an ETA refusal, but you can reapply if your circumstances change.

Common reasons for refusal include:

• Previous overstay or visa violation.
• Criminal convictions (especially serious or recent).
• Incorrect or incomplete application.
• Being a threat to national security.

If you're refused, you'll receive a letter explaining why. You can then decide whether to apply for a visa or address the issue.

What to do if your ETA is cancelled

If your ETA is cancelled after approval, you will be notified by email. The cancellation may happen if you commit a crime in the UK or if your passport is reported stolen. You should check your email regularly before travel.

For example, if you are arrested for a minor offence during a previous visit, the Home Office may cancel your ETA for future trips. You would then need to apply for a visa and provide additional documentation.

UK ETA vs EU ETIAS: what's the difference?

Both are similar systems, but for different destinations. The UK ETA is for travel to the United Kingdom. The EU ETIAS (European Travel Information and Authorisation System) is for travel to the Schengen Area (most EU countries plus Iceland, Norway, Switzerland, etc.).

Key differences:

• Cost: UK ETA £20; ETIAS €20.
• Validity: UK ETA 2 years; ETIAS 3 years.
• Application: Both online, but ETIAS may require more background info.
• Scope: UK ETA for UK only; ETIAS for 27 European countries.

If you're travelling to both the UK and the Schengen Area, you'll need both authorisations. They are separate systems.

Which system is easier to use?

Both are designed to be user-friendly. The UK ETA application is shorter, with fewer questions. The ETIAS may ask for more travel history details.

For most travellers, both take less than 15 minutes to complete.

Consider a traveller from Australia planning a trip to London and Paris. They would need a UK ETA for the UK leg and an ETIAS for the Schengen leg. Applying for both in advance ensures smooth travel.

Common questions about the UK ETA

Do children need a UK ETA?

Yes. Every traveller, including infants and children, needs their own ETA. You apply for each child separately.

The fee is £20 per person, regardless of age.

Can I apply for a UK ETA if I have dual nationality?

Yes. You should apply using the passport you intend to travel with. If you hold a passport from a visa-free country, you can use that for the ETA.

If one of your nationalities requires a visa, you must use that passport and apply for a visa instead.

What if my UK ETA application is rejected?

You cannot appeal, but you can reapply if your circumstances change. Alternatively, you can apply for a standard visit visa – but that costs more and takes longer. Check the refusal letter for details.

Do I need a UK ETA if I'm just transiting?

Yes. If you are passing through UK border control (even if you stay airside), you need an ETA. This includes connecting flights where you change terminals.

The only exception is if you are a visa national who qualifies for the Transit Without Visa scheme – but that's rare.

How do I check if my UK ETA is still valid?

You can check the status of your ETA on the official gov.uk website. You'll need your passport number and the application reference. It's a good idea to check before you travel, especially if you applied months ago.

Additional considerations for first-time applicants

First-time applicants often worry about the process. Rest assured, the system is designed to be simple and accessible. You do not need any special technical skills to complete the form.

One key tip is to apply well in advance of your travel date. While most approvals come within minutes, you should allow up to 72 hours. Last-minute applications can cause stress if there is a delay.

If you have any doubts about your eligibility, check the official guidance first. You can also contact the UK Home Office helpline for clarification, though response times may vary.

Preparing for your trip after ETA approval

Once your ETA is approved, you should double-check that your passport details match those on the authorisation. Any discrepancy could cause problems at the border. Keep a digital or printed copy of the approval email for your records.

Also, ensure your passport is valid for the entire duration of your trip. While the ETA is linked to your passport, you still need a valid travel document to enter the UK. If your passport is damaged or expires soon, renew it before applying.

For example, a traveller with a passport expiring in 6 months should renew it first. Then apply for the ETA with the new passport to maximise the 2-year validity period.

Understanding the UK ETA for business travellers

Business travellers can use the ETA for meetings, conferences, and negotiations. You cannot, however, take up employment or provide services to a UK client while on an ETA. If your business activities involve paid work, you may need a visa.

For instance, a US consultant attending a single board meeting in London can use an ETA. But if they are hired to lead a training session for a UK company, that may constitute work and require a visa.

Always clarify the nature of your business trip with your employer or legal adviser. The UK Home Office provides specific guidance on permitted business activities under the ETA scheme.

Permitted paid engagements explained

The ETA allows certain paid engagements, such as lecturing, performing, or judging. These are limited to specific events and cannot be part of a regular employment arrangement. You must not be paid by a UK source for ongoing work.

For example, a Canadian professor invited to give a one-time lecture at a UK university can use an ETA. But a series of lectures over several weeks may require a visa. Check the official list of permitted paid engagements before you travel.
