What Is a UK ETA and Why It Matters in 2026
The UK Electronic Travel Authorisation is a digital pre-travel permission tied directly to your passport. It isn't a visa. It's a lighter-touch clearance for visitors who already enjoy visa-free entry, and it sits in the airline's system before you ever reach a check-in desk.
Here's what matters for 2026. The ETA is paid per applicant, runs for two years or until your passport expires, and supports multiple journeys with stays of up to six months. From 2 April 2025, eligibility expanded to EU and other European nationals, so most short-stay visitors now fall inside the scheme, which became fully mandatory on 25 February 2026.
This guide covers the gaps most articles skim past: refusal grounds, transit edge cases, nationality-by-nationality eligibility, and the EUSS exemption that catches Australians with prior UK ties off guard.
What this guide covers:
- Who needs an ETA and who's exempt, by nationality and status
- The current cost and how to apply online
- What happens if your application is refused or delayed
- The transit and family rules travellers most often get wrong
- Answers to the most common ETA questions
Do I Need an ETA to Enter the UK? Eligibility by Nationality
If you hold a visa-exempt passport and are visiting the UK for tourism, business, or short study of up to six months, you need an ETA before you board. That's the short answer. The longer one depends on which passport you carry and what status, if any, you already hold in the UK.
Some travellers are exempt. British and Irish citizens, including dual nationals, sit outside the scheme entirely. So do travellers holding any UK immigration status, whether that's a work visa, a study visa, a family route, or indefinite leave to remain. EU citizens with EUSS settled or pre-settled status also skip the ETA.
For everyone else with a visa-free passport, the requirement applies. That includes US, Canadian, Australian, New Zealand, EU/EEA, and GCC nationals such as travellers from the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait and Oman. The rollout was staged: GCC nationals were among the first groups brought into scope, and European nationals followed from 2 April 2025.
Transit is the bit travellers get wrong most often. Rules for airside transit are tightly defined and have changed over time, so confirm your specific route and airport before assuming you can connect without one. Stepping through UK passport control, even for a short layover, brings you firmly within the requirement.
Families don't get a group pass. Every traveller needs their own ETA regardless of age, including infants and children. A family travelling together submits a separate application for each member, with one approval linked to each individual passport.
The table below summarises the most common nationality positions.
| Nationality | ETA Required? | Notes |
|---|---|---|
| United States | Yes | Visa-free for short stays up to 6 months; ETA needed before boarding |
| Canada | Yes | Same short-stay rule; each family member applies individually |
| Australia | Yes | ETA required for tourism, business, or short study |
| EU citizens (no EUSS status) | Yes | In scope from 2 April 2025; applies to most European travellers |
| EU citizens with EUSS settled/pre-settled status | No | EUSS status itself covers entry; no ETA needed |
| GCC nationals (UAE, Saudi Arabia, Qatar) | Yes | Among the first nationalities brought into the scheme |
| British and Irish citizens | No | Outside the scheme entirely, including dual nationals |
| Travellers with a valid UK visa | No | Any current UK immigration status overrides the ETA requirement |
How Much Does a UK ETA Cost and How to Apply Online
A UK ETA is paid online per applicant at the time of application, and the fee has risen more than once since the scheme launched — so always confirm the current amount before applying. Each traveller pays their own fee, and the approval links to the specific passport used during the application, not to a household or booking reference.
Applying is straightforward in the standard case. You apply online through the official UK ETA app or government website, upload a digital photo that meets the published standards, enter passport and contact details, and answer a short set of suitability and criminality questions. Payment is taken on submission.
What you'll need on hand: a valid passport, a compliant digital photo, a payment card, and current contact details. Each person travelling submits their own application and must travel on the same passport used in that application.
Processing usually moves quickly. Many decisions arrive within minutes, though some take up to a few working days. Apply at least three working days before travel, and earlier if your itinerary involves a tight connection or a non-refundable booking.
Conventional advice says apply yourself and save the service fee. For a clean profile, that's fair. The contrarian read is that the application fee is the cheapest line on a UK trip, while the rebooked flights and forfeited accommodation that follow a refusal are not. Prior refusals, criminal record disclosures, dual nationality, and previous immigration breaches are the cases where a single tick-box mistake costs far more than the fee. If you're heading to the UK on a longer-term plan, the UK working holiday route sits in a different category entirely and needs a proper visa application, not an ETA.
What Happens If Your UK ETA Is Refused or Delayed
There is no formal appeal process if your UK ETA is refused, but you can apply for a Standard Visitor visa instead. That's the most important thing to know upfront. A refusal isn't the end of your trip. It's a redirect.
Refusals usually come down to a few patterns. Previous immigration breaches like overstaying or working in breach of conditions can trigger a refusal under suitability rules. Serious criminal convictions are another flag. Even incomplete or inconsistent answers on the application form can stall a decision or push it into refusal until the gaps are clarified.
If you're refused, the practical next step is a Standard Visitor visa application supported by evidence of your travel purpose, ties to your home country, and financial means. This route involves a fuller assessment by an Entry Clearance Officer, so leave time for it.
For delays beyond a few working days, check your application status before contacting UKVI. Hold off on non-refundable bookings until you have written approval. Never travel on the assumption that an ETA will land in time.
Understanding when an ETA suffices versus when you need a full visitor visa matters here. For straightforward short visits from eligible nationalities, the ETA works. For longer stays, work-adjacent activities, or after a refusal, the UK Visit Visa route is the alternative most travellers from Australia turn to.
UK ETA Frequently Asked Questions
How much does a UK ETA cost in 2026?
The UK ETA fee is set by the Home Office and paid online per applicant at the time of application. The fee has increased more than once since the scheme launched, so always confirm the current amount on application before paying. Every traveller needs their own ETA, including infants and children. OlaVisa's pre-submission review verifies fee and applicant details before payment is processed.
How long is a UK ETA valid?
A UK ETA is valid for 2 years or until your passport expires, whichever comes first. Within that window, it permits multiple journeys to the UK for stays of up to 6 months at a time. If you renew your passport, you'll need to apply for a new ETA, because the authorisation is digitally linked to a specific passport.
Do I need a UK ETA if I'm only transiting through a UK airport?
In most cases, yes. Travellers from ETA-eligible nationalities generally need an ETA even for short transits, with limited exemptions for some airside connections. Rules in this area are tightly defined and have changed over time, so confirm your specific route and airport before assuming you can transit without one.
Do EU citizens with settled status need a UK ETA?
No. EU, EEA, and Swiss citizens holding settled or pre-settled status under the EU Settlement Scheme do not need a UK ETA. The same exemption applies to anyone with existing UK immigration status, including work, study, family visas, or indefinite leave to remain. You travel using the status you already hold.
What happens if my UK ETA application is refused?
There is no formal appeal against an ETA refusal. The standard path forward is to apply for a Standard Visitor visa, supported by documentation showing your travel purpose, ties to home, and financial means. Refusals often relate to past immigration history, criminal records, or incomplete information on the application form.
How long does it take to get a UK ETA?
Many ETA decisions arrive within minutes, but the Home Office advises that decisions can take up to a few working days. Apply at least three days before travel as a buffer. Avoid booking non-refundable flights or accommodation until your approval is confirmed in writing.
Ready to Apply for Your UK ETA With Confidence?
