UK ETA 2026: Who Needs One, How to Apply, and the Two Traps That Get People Denied Boarding

If you’re American, Canadian, Australian, or from an EU country and you’re flying to the UK, you need an Electronic Travel Authorisation before you get on the plane. Not on arrival. Before boarding.

That’s been true on paper since January 2025, but the grace period is over. Since February 25, 2026, enforcement is strict and discretion-free: carriers cannot board a passenger who needs an ETA and doesn’t have one. No ETA, no flight, no ferry, no Eurostar.

For most people this is a ten-minute errand and a £20 charge and you’ll never think about it again. The problem is the minority who get caught out, and they get caught out in three predictable ways: a connection they assumed was exempt, a trip to Belfast via Dublin, and a decades-old conviction they didn’t think counted.

Here’s all of it.

The basics

ETA detail	Requirement
What it is	Digital permission to travel — not a visa
Cost	£20 per person, since April 8, 2026 (was £16)
Valid for	2 years, or until your passport expires — whichever comes first
Allows	Multiple visits, up to 6 months each
Who pays	Every traveler individually, including infants
Where to apply	The UK ETA app or GOV.UK — nowhere else
Decision time	Usually minutes; allow 3 working days

The ETA is linked electronically to the passport you applied with. There’s nothing to print and nothing to carry — carriers check it against your passport through Advance Passenger Information. You just travel on the passport you used.

It’s also worth being clear about what it isn’t: the ETA is permission to travel, not permission to enter. A Border Force officer still makes the entry decision when you land.

Do you actually need one?

You need an ETA if you’re from one of roughly 85 visa-exempt nationalities — the US, Canada, Australia, New Zealand, all 27 EU states, Gulf states, and many others — and you’re visiting the UK for up to six months without an existing UK immigration status.

You don’t need one if:

You’re a British or Irish citizen.

You hold a valid UK visa or immigration status — work, study, family, or settled/pre-settled status under the EU Settlement Scheme.

You’re traveling on a British Overseas Territories Citizen or BN(O) passport.

You’re legally resident in Ireland, from a visa-exempt nationality, and traveling into the UK from within the Common Travel Area — with proof of Irish residence if asked. (More on this below, because it’s the single most misunderstood exemption.)

You’re transiting airside only at Heathrow or Manchester without crossing the border. (Also below. Also misunderstood.)

You’re an accredited diplomat traveling on official business.

Dual nationals: read this bit twice. If you hold British or Irish citizenship alongside another nationality, you cannot get an ETA on your other passport. The system won’t issue you one. You must travel on your British or Irish passport, or on another passport containing a valid Certificate of Entitlement. If your British or Irish passport has expired, renew it — as of February 25, 2026 there’s no discretion at the gate, and “I’m actually a British citizen, my passport just lapsed” is not a boarding pass.

How to apply

Two legitimate routes, and only two:

The UK ETA app (Home Office, on the App Store and Google Play) is the faster one. It walks you through photographing your passport, scanning the chip via NFC, scanning your face, taking a photo, answering the security questions, and paying. About ten minutes. You don’t need your travel details — no flights, no hotels.

GOV.UK at gov.uk/electronic-travel-authorisation if your phone lacks NFC or the app won’t cooperate.

You’ll get a decision by email from UK Visas and Immigration, usually within a day, containing a 16-digit reference number. Wait for that email before you travel. If nothing arrives within three working days, check your spam folder first, then contact UKVI. You can verify status any time via the Check My ETA service on GOV.UK.

Practical notes from people who’ve had trouble:

The NFC chip read is the main friction point. App reviews are full of people taking many attempts to get a passport chip to read, sometimes restarting the app. Do this at home with time in hand, not at the airport.

Photo quality causes most automated delays. Plain light background, full head and shoulders, neutral expression, eyes visible, even lighting, no glare on glasses. The passport page image needs to be sharp and show the whole page including the two MRZ lines at the bottom.

Don’t submit twice. Duplicate applications flag your file for review and slow everything down.

Apply early. The official minimum is three working days. If you have any immigration or criminal history that might prompt a question, give yourself one to two weeks — and read the criminality section below before you file anything.

Since the ETA is valid for two years and priced per application rather than per trip, there’s no reason to wait.

Trap one: the transit exemption is narrower than it sounds

There is an airside transit exemption. It applies at London Heathrow and Manchester only, it’s been in place since January 2025, and the Home Office describes it as temporary and keeps it under review.

The rule underneath it is simple: if you don’t cross UK passport control, you don’t need an ETA. If you cross it for any reason, you do.

Where people get this wrong is assuming that “I have a connection at Heathrow” and “I’m an airside transit passenger” are the same statement. They are not.

You’re exempt if: your journey is booked on one ticket, your bags are checked through to your final destination, you follow Flight Connections signs, and you never reach an immigration desk or e-gate.

You need an ETA if any of these apply:

You booked two separate tickets and are self-transferring. Heathrow doesn’t treat separately-ticketed passengers as connecting passengers at all — you must clear immigration, collect your bags, and check in again.

You have to collect baggage for any reason.

Your terminal change routes you landside.

You go through an e-gate or show your passport to a Border Force officer.

You’re connecting at Gatwick, Stansted, Luton, Birmingham, Edinburgh, Glasgow or anywhere else. The exemption is Heathrow and Manchester, full stop.

If that one-ticket-versus-two distinction sounds familiar, it’s the same fault line that determines whether you get rebooked or rebuy when Europe’s Entry/Exit System queues make you miss a connection. Separate tickets are the most expensive default setting in modern travel.

Given that an ETA costs £20 and lasts two years: if there’s any ambiguity about your connection, just buy one. The exemption could also be withdrawn — it’s explicitly under review — and an ETA you didn’t strictly need costs you twenty pounds, while one you did need and don’t have costs you the trip.

Trap two: Dublin to Belfast

This one catches a very specific and very common itinerary: American tourists who fly into Dublin, rent a car, and drive north to see the Giant’s Causeway.

The Common Travel Area exemption is real, but it’s for people who live in Ireland — not people visiting it. A US citizen resident in Cork traveling to Belfast doesn’t need an ETA. A US tourist who landed in Dublin on Tuesday does.

Here’s what makes it genuinely hazardous rather than merely confusing: there are no immigration controls whatsoever on the Ireland–Northern Ireland land border. Nobody will stop you. You can drive from Donegal to Derry without meeting a single official.

You’d also be in the UK without the permission you’re required to hold. That’s a problem you may never encounter — or one you encounter later, at an unrelated moment, when it’s on your immigration record.

If your trip includes both Ireland and Northern Ireland, get the ETA. It’s £20. Northern Ireland’s tourism industry has lobbied for a visitor exemption on exactly this route and hasn’t got one.

(Worth knowing for the wider itinerary: Ireland is outside both the ETA scheme and the EU’s Entry/Exit System, which makes it an unusually frictionless entry point into Europe right now.)

The criminal record question — and a change from March 2026

This is the part almost no travel content covers, and it’s where the real damage happens.

The ETA application asks about criminal history, and the rules are stricter than most travelers assume.

Mandatory refusal applies where you’ve been convicted — in the UK or anywhere else — and received a custodial sentence of 12 months or more, regardless of how long ago it was. There’s no time limit on that one.

As of March 26, 2026, that was extended to suspended sentences of at least 12 months. This is new, it’s recent, and it produces a genuinely strange outcome: someone who served eleven months in prison faces a discretionary refusal, while someone who received a twelve-month suspended sentence that was never activated now faces a mandatory one.

Refusal is also mandatory for a conviction resulting in a non-custodial sentence or out-of-court disposal unless more than 12 months have passed since the conviction.

And you must declare more than people expect: fines, penalty orders, suspended sentences, community service orders, and settlements. Minor administrative penalties like parking and speeding fines generally fall outside this, but if you’re unsure, check rather than guess — using deception in a UK immigration application risks a ten-year ban.

Here’s the practical problem. An ETA application gives you no room to explain yourself. You can upload a passport photo and nothing else — no court documents, no character references, no evidence of rehabilitation. You get a text box with a 1,000-character limit. That’s it.

And there is no appeal. If your ETA is refused, your only route is a Standard Visitor Visa — which costs considerably more, takes far longer, and requires documentation you could have submitted in the first place.

So the advice from UK immigration practitioners is consistent and worth repeating: if you have a criminal record of any significance, apply for a Standard Visitor Visa directly instead of trying the ETA. A refused ETA can prejudice the visa application that follows it.

A refusal is different from a rejection, incidentally. A rejected application — incomplete, technically deficient — comes with a reason and you can reapply. A refusal is a substantive decision, and it closes the door.

For context: approval rates run around 99.6 percent, and more than 30 million ETAs have been issued since launch. The overwhelming majority of people fill this in and forget about it. But if you’re in the small group with history, don’t find out at the airport.

Nobody is authorised to sell you an ETA

The UK government does not authorise any third-party website to handle ETA applications. Not one. There is no “official partner,” no “authorised agent,” no expedited channel.

The scam economy around this is substantial. Consumer watchdogs have documented fraudulent sites charging many times the official fee. The Home Office directs travelers to GOV.UK or the official ETA app and warns that another website cannot get you a faster decision.

The three tiers you’ll encounter:

Outright fraud. Sites that take your passport number, date of birth, and card details and never file anything. You find out at the airport.

Inflated middlemen. Sites that genuinely do submit your application but charge £60–£150 for “processing,” “review,” or “express handling.” All ETAs are processed by the Home Office at identical speed regardless of origin. You are paying for nothing.

The legitimate but unnecessary. A few disclosed visa services charge a transparent fee for form-filling help. Not fraud — but you’re paying someone to spend ten minutes on an app you could use yourself.

How to stay safe:

The URL must end in gov.uk. Nothing else is the government. Not .com, not .co.uk, not .org, not a hyphenated variant.

The app must be published by the UK Home Office. Check the developer name in the store listing.

£20 is the price. Any total above that includes someone else’s margin.

Don’t click ads. Fraudulent sites buy sponsored placement and routinely sit above the real one in search results.

“Guaranteed approval” is always a lie. Only the Home Office decides.

Every travel scam runs on the same fuel: you don’t know what normal looks like, so a fake fee looks like a real one. That’s the whole reason I built Good Trip — scam warnings for the UK, Ireland and 24 other countries, offline, free, no account, no data collected.

A few things that catch people later

New passport, new ETA. The authorisation is tied to the passport you applied with. Renew your passport and you need a fresh ETA, even if the old one hasn’t hit two years.

The two-year clock can be shorter than two years. Validity is two years or passport expiry, whichever is sooner. If your passport has fourteen months left, that’s what you’re buying.

Children need their own. Every traveler applies individually and pays individually, infants included. If you’re applying on someone else’s behalf through the app, they need to be physically with you.

Six months is a maximum, not an entitlement. The ETA lets you seek entry for up to six months per visit. Border Force still decides, and a pattern of long, frequent visits invites questions.

Where this sits alongside Europe

Three systems, constantly confused with each other:

UK ETA — live and enforced now. £20, apply in advance, needed for the UK including Northern Ireland.

EU Entry/Exit System (EES) — live since April 2026. Biometric registration at the border. Nothing to apply for, nothing to pay. See our EES and border guide.

EU ETIAS — not live. €20 when it arrives, currently expected 2027 with no confirmed date. Nobody can sell you one today. See our ETIAS explainer.

If a website offers to sell you ETIAS right now, it is stealing from you. That one isn’t a judgment call.

Before you fly

The ETA is the easy part. The hard part is the first hour on the ground in a country you don’t know — which taxi, which rate, which of the three men offering to help with your bags is running a scam.

That’s why I built Good Trip. It’s a free app with destination-specific scam warnings, an offline phrasebook, a currency converter, local emergency numbers, and step-by-step eSIM setup — for the UK, Ireland and 24 other countries. All of it works offline, so it’s on your phone before you’ve cleared the terminal.

No account. No data collected. Download it before you fly.
