ETA: What You Need to Know

By Stevie Hayes | Last updated: February 2026

Quick Answer

From 2025, citizens of over 50 countries who previously visited the UK visa-free must obtain Electronic Travel Authorisation (ETA) before boarding their flight. The £10 ETA must be approved before travel—arriving without one means being turned away at the border. Most applications are approved within three days, but the days of spontaneous trips to Britain are over for much of the world.

The End of Spontaneous Travel

If you're American, Australian, Canadian, or from one of dozens of other countries, you used to be able to book a flight to London tonight and arrive tomorrow. No visa. No advance permission. Just your passport and a sense of adventure.

Those days are gone.

The Electronic Travel Authorisation system means you now need pre-approval to visit Britain—even for a long weekend. It's not a visa, but it's not nothing either. It's a screening check that happens before you board your plane, not when you land.

Who Needs an ETA?

The ETA requirement applies to non-visa nationals—people from countries whose citizens could previously visit the UK without a visa for up to six months.

Countries Requiring ETA (Partial List)

The full list covers around 50 nationalities. If you previously didn't need a visa to visit the UK, you almost certainly need an ETA now.

Who Doesn't Need an ETA?

• Irish citizens — Common Travel Area arrangements continue
• British citizens and nationals — Obviously
• Those with existing UK visas — Your visa covers you
• EU Settlement Scheme participants — Your status covers you
• Those with valid leave to remain — No ETA needed

How the ETA System Works

Application Process

1. Download the UK ETA app or visit the GOV.UK ETA website
2. Create an account with your email address
3. Upload a photo of yourself (selfie-style, like a passport photo)
4. Scan your passport using your phone's camera
5. Answer security questions about criminal history, immigration violations, etc.
6. Pay the £10 fee by card
7. Wait for approval — usually within three working days

What They're Checking

The ETA system screens for:

• Immigration history — Previous overstays, visa refusals, deportations
• Criminal background — Serious offences that might bar entry
• Security concerns — Watchlist checks and terrorism-related screening
• Health risks — In some circumstances

Most applications are approved automatically within hours. Complex cases take longer.

When Things Go Wrong

ETA refusals happen. If you're refused, you'll receive an email explaining why (in general terms) and your options.

Common Reasons for Refusal

Your Options After Refusal

Request reconsideration — If you believe there's been an error, you can ask for your application to be reviewed. This isn't a formal appeal but can correct mistakes.

Apply for a visa — If you're refused an ETA, you may still be able to apply for a Standard Visitor visa. This is a more thorough process but allows you to provide evidence and explanations.

Seek immigration advice — For complex refusals, particularly those involving criminal history or previous immigration issues, professional advice may help.

Planning Your Trip

The ETA changes how you should approach UK travel:

Before You Book

• Apply for your ETA first — Don't book non-refundable flights before you have approval
• Allow processing time — Three days is typical, but plan for longer
• Check passport validity — Your passport should be valid for your entire stay

At Check-In

Airlines will verify your ETA status before allowing you to board. No ETA, no boarding pass. This happens at the departure airport, not when you arrive in the UK.

At the UK Border

Having an ETA doesn't guarantee entry. Border officers can still refuse admission if they have concerns about your visit. But for most travellers, the ETA pre-approval makes border processing faster.

ETA Validity

Your ETA is linked to your passport. If you get a new passport, you need a new ETA.

Business Travellers: Special Considerations

If you travel to the UK regularly for business, the ETA system has specific implications:

What You Can Do on an ETA

• Attend meetings and conferences
• Negotiate and sign contracts
• Conduct site visits
• Provide advice and consultancy (if employed abroad)
• Install or service equipment (certain conditions)

What You Cannot Do on an ETA

• Work for a UK employer
• Provide services directly to UK clients for payment
• Start a business
• Take employment of any kind

The line between permitted business activities and work requiring a visa isn't always obvious. When in doubt, check before you travel.

Families and Group Travel

When travelling with family, remember:

• Every person needs their own ETA — Including children
• Apply for all family members together — Using the app, you can add multiple travellers
• Children's passports — Must be valid; children need their own passports
• Different nationalities — If family members hold different passports, each applies according to their nationality

---

Transit Through the UK

Even if you're just changing planes at a UK airport, you may need an ETA or transit visa depending on your nationality and circumstances.

Airside Transit

If you're staying within the airport (not passing through immigration):

• Most ETA-requiring nationals can transit airside without an ETA
• Some nationalities require a Direct Airside Transit Visa (DATV)
• Check your specific nationality's requirements

Landside Transit

If you need to pass through immigration (to change terminals, collect baggage, or leave the airport):

• You need an ETA (or visa)
• All standard ETA rules apply

Practical Tips

Apply Early

Don't wait until the night before your flight. While most ETAs are approved within hours, delays happen. Apply at least a week before travel.

Triple-Check Your Details

Passport number errors are the most common cause of application problems. Enter details exactly as they appear in your passport.

Keep Confirmation Accessible

Save your ETA approval email and take a screenshot. While the ETA is electronically linked to your passport, having confirmation available helps if systems have issues.

Monitor Your Email

If there's a problem with your application, the Home Office will contact you by email. Check your spam folder.

Understand the Limits

An ETA lets you visit for up to six months at a time—but immigration officers can grant shorter periods if they have concerns. Six months isn't guaranteed.

Frequently Asked Questions

Is an ETA the same as a visa?

No. An ETA is a travel authorisation, not a visa. It's simpler to obtain but offers fewer rights. You can't work, study, or access public funds on an ETA.

Can I apply on arrival?

No. You must have an approved ETA before you travel. Airlines won't let you board without one.

What if my ETA is refused?

You can request reconsideration or apply for a Standard Visitor visa. A visa application allows you to provide supporting documents and explanations.

How long does approval take?

Most applications are approved within three working days. Some take longer if additional checks are needed.

Can I extend my stay?

Generally, no. Visitor status (whether on an ETA or visitor visa) cannot normally be extended. You must leave before your permitted stay expires.

The Bottom Line

The ETA system isn't complicated, but it does require planning. The spontaneity of last-minute UK trips is largely gone for those who need ETAs. Apply early, check your details carefully, and don't book travel until you have approval.

For most people, the ETA will be a minor inconvenience—£10 and a few days' wait. But understanding the system, and what to do if problems arise, ensures your British adventure starts smoothly.
