UK ETA 2026: Who Needs It, Cost & How to Apply (Complete Guide)

If you’re a US, EU, Canadian, Australian, or other visa-exempt traveler planning a UK trip in 2026, you now need a UK ETA before you fly — not a visa, but you can’t board without one either. Here’s exactly who needs it, what it costs, and how to apply without getting caught out at check-in.

What Is the UK ETA?

The UK Electronic Travel Authorisation (ETA) is a digital permission to travel that links to your passport electronically — there’s no stamp or sticker. It launched in October 2023 and by the end of 2025 the UK government had issued over 24.8 million of them, according to the Home Office. It is not a visa. It doesn’t require an interview, a biometrics appointment, or weeks of processing. Most applicants get a decision within minutes to a day.

An ETA lets you enter the UK, Jersey, Guernsey, or the Isle of Man for tourism, visiting family, or short business trips, with each visit capped at up to six months.

Who Needs a UK ETA in 2026?

Since the scheme’s rollout completed, most visa-exempt nationalities now need an ETA to travel to the UK — including travelers from the United States, the EU/EEA, Switzerland, Canada, Australia, New Zealand, Japan, South Korea, Singapore, and the Gulf states.

You DO need an ETA if…	You DON’T need an ETA if…
You’re a visa-exempt visitor coming for tourism, family visits, or short business trips	You hold a British or Irish passport
You’re transiting “landside” through UK border control before an onward flight	You already have permission to live, work, or study in the UK
You’re traveling with children or infants — each person needs their own ETA	You hold a UK visa that already covers your visit

Not sure which category you fall into? The official gov.uk visa checker confirms exactly what you need based on your nationality and purpose of travel.

How Much Does a UK ETA Cost?

A UK ETA costs £20 per person, whether you apply through the official app or online, and the fee is non-refundable even if your application is rejected. Every traveler needs their own ETA, including babies and children, so a family of four should budget £80 in total.

Be careful where you apply: several third-party websites mimic the official government service and charge inflated fees. The only place to pay the real £20 rate is via the UK ETA app or gov.uk/eta/apply.

How to Apply for a UK ETA

You have two options, and both ask for the same basic information: the passport you’ll travel with, an email address, and a payment method (credit card, debit card, Apple Pay, or Google Pay).

Option 1: The UK ETA App

The official app (available on the App Store and Google Play) uses your phone’s camera to scan your passport chip and take a live photo of your face. This is the fastest route and lets you apply on behalf of someone traveling with you.

Option 2: Apply Online

If you can’t use the app, you can apply on gov.uk by uploading a photo of your passport and a photo that meets the UK’s digital photo rules. If you’re applying for someone who isn’t traveling with you, this is the only route available.

After you submit, most decisions arrive by email within a day, though it can take up to three working days. You’ll receive a 16-digit ETA reference number — hold onto that email, since you can’t fly until it lands. If nothing arrives after three working days, check your spam folder before contacting UK Visas and Immigration through their webchat (phone support isn’t available for ETA queries).

How Long Does a UK ETA Last?

Once approved, a UK ETA is valid for two years, or until your passport expires — whichever comes first. During that window, you can travel to the UK as many times as you like; you don’t need to reapply for each trip, only when your ETA or passport lapses.

UK ETA vs UK Visa vs ETIAS: Don’t Mix Them Up

Travelers heading to Europe this year are juggling three different systems, and it’s easy to confuse them. Here’s the quick version:

	UK ETA	UK Visa	ETIAS (EU)
Applies to	Visa-exempt visitors to the UK	Nationalities requiring a visa, or longer/other visit types	Visa-exempt visitors to the Schengen Area
Cost	£20	Varies by visa type	Not yet launched (expected ~€7)
Processing	Minutes to 3 working days	Weeks, may require appointment	N/A — delayed indefinitely
Validity	2 years or passport expiry	Set by visa terms	Not yet launched

If your trip also includes mainland Europe, it’s worth reading how the EU’s parallel system already works today in our EU Entry/Exit System (EES) 2026 guide and our ETIAS 2026 guide — the two are frequently confused with the UK’s ETA but work completely differently.

Common UK ETA Mistakes to Avoid

• Applying too close to departure. Most decisions are fast, but 3-working-day cases happen — apply at least a few days before you fly, not at the airport.
• Forgetting kids and babies. Every traveler needs their own ETA, regardless of age.
• Assuming a valid ETA guarantees entry. An ETA lets you travel to the UK border; a Border Force officer still makes the final entry decision.
• Paying more than £20. If a site is charging significantly more, it’s not the official government service.
• Ignoring transit trips. If you’re passing through a UK airport’s border control before connecting onward, you still need an ETA — check with your airline if you’re unsure whether your connection counts.

Staying Connected on Your UK Trip

Once your ETA comes through, the next thing worth sorting before you land is data. Between pulling up your ETA confirmation email at the border, navigating from the airport, and messaging whoever’s picking you up, you’ll want a working connection the moment you touch down — not after you’ve found airport WiFi or queued for a SIM counter.

An eSIM you activate before departure solves this cleanly: no swapping physical SIM cards, no roaming surprises on your home carrier’s bill, and if your trip continues into the EU afterward, a multi-country eSIM plan carries over without needing a new SIM at every border. WoWoSIM covers the UK and 196 other countries with plans that activate in minutes, so the only queue you’ll be standing in is passport control.

FAQ: UK ETA 2026

Do I need a UK ETA if I’m just transiting through a UK airport?
Yes, if you pass through UK border control (“landside”) before your connecting flight. If you stay in the international transit area without clearing border control, check with your airline.

Can I apply for my children’s ETA?
Yes. Every traveler needs an individual ETA, including babies, and you can apply for family members traveling with you through the app.

What happens if my ETA application is rejected?
The £20 fee is non-refundable, and you’ll need to submit a new application with corrected details.

Is a UK ETA the same as ETIAS?
No. ETIAS is the EU’s still-unlaunched equivalent for the Schengen Area. The UK ETA is separate, already fully in effect, and does not cover travel to EU countries.

How long before my trip should I apply?
Most applicants get an answer within a day, but apply at least three working days before departure to leave room for delays.

Bottom Line

The UK ETA is quick, cheap, and now required for most visa-exempt visitors — but only if you apply through the official channel and leave a few days of buffer before you travel. Sort your ETA, download your airline boarding pass, and get your connectivity sorted before you land: check WoWoSIM’s UK and Europe eSIM plans so you’re online from the moment you clear the border.
