Most UK electronic travel authorisation decisions arrive faster than travellers expect, often within minutes of submitting through the official app. The official guidance still asks you to allow up to three working days, and a small share of applications genuinely need that long. Both figures are true, and the gap between them is where trip planning goes wrong. This guide covers the realistic wait in 2026: how a typical approval unfolds, what triggers a longer review, what three working days means from Australia, and what to do if the wait stretches.
In short
- Most ETA applications receive an automatic decision within minutes, and usually within a day.
- The official reference is up to three working days, Monday to Friday on UK time, so weekends and UK public holidays do not count.
- A small number of applications go to manual review, most commonly where answers to the background questions need a closer look.
- There is no priority or express option for the ETA; no website, app or agency can buy you a faster government decision.
- Apply when you book your trip. An approved ETA lasts two years, so applying early costs you nothing.
- If three working days pass with no decision, check your spam folder and confirm your submission email before contacting anyone, and do not lodge a second application.
How long does a UK ETA really take?
Most applicants get a decision within minutes, but the honest planning figure is up to three working days. Submitting the application itself takes around ten minutes through the official UK ETA app. From there, the majority of applications are decided automatically: the system runs its checks, finds nothing that needs a human decision, and sends an approval email. Official guidance describes decisions as usually arriving within a day. The three-working-day allowance exists for the small minority of applications that get referred for a closer look.
| Scenario | Realistic timeframe |
|---|---|
| Straightforward application through the official app | Automatic decision, often within minutes and usually within a day |
| Application referred for manual review | Up to three UK working days |
| Submitted just before a UK weekend or public holiday | The working-day clock pauses, so allow into the following week |
| ETA refused, moving to a visit visa instead | Around three weeks of visa processing, a different planning horizon altogether |
What the typical approval looks like
For most Australian travellers the sequence is submit, receive a confirmation email, then receive a decision email, often all on the same day. The confirmation email proves your application was lodged. The decision arrives in a separate email containing your ETA reference number, and the authorisation is linked electronically to the passport you applied with, so there is nothing to print or carry. One quirk worth knowing for families: decisions are made per person, not per booking, so four applications lodged in the same sitting can come back at four different times, and one member waiting longer than the rest says nothing about the outcome.
What sends an application to manual review
Applications slow down when something in them needs a human decision, most commonly an answer to the background questions that requires checking. The application asks about criminal convictions and any other nationalities you hold. Answering yes to the criminality questions is the clearest trigger for manual review: published guidance from established immigration law firms consistently describes declared convictions and adverse immigration history as the situations that take an application out of the automatic queue and put it in front of a caseworker. A referral is not a refusal. It simply means a person, working UK hours, now has to look at your file, and that is what the three working days are for.
Details that cannot be verified automatically can have the same effect. The important thing is to answer every question honestly and exactly as your documents state, because an inconsistent answer creates a far worse problem than a slow one. If you are unsure whether the ETA is even your correct route, for instance as a British-Australian dual national, OlaVisa's eligibility screening identifies these category mismatches before fees are paid.
What three working days means when you live in Australia
The clock runs Monday to Friday on UK time, which means movement on your application tends to land overnight in Australia. The UK sits roughly 9 to 11 hours behind Australian eastern time depending on the season, so a UK business day starts around your late evening and ends while you sleep. In practice, a manually reviewed application often shows no progress during your Australian daytime, then resolves overnight.
Weekends compound this. An application lodged on your Saturday morning arrives late on the UK's Friday, and if it needs human review, the clock does not start until the UK's Monday. UK public holidays widen the gap further, and they do not line up with Australian ones: UK bank holidays cluster around Easter, May, August and Christmas. A realistic worst case, an application lodged just before a UK long weekend that then needs review, can span close to a week of calendar time. Most travellers never notice any of this because their decision is automatic, but the buffer exists for the ones who do.
When should you apply?
Apply when you book your flights; an approved ETA lasts two years, so there is no advantage in waiting. Official guidance recommends applying at least three working days before travel, and booking time is the natural moment: the timing question disappears entirely, and the same ETA covers repeat trips of up to six months each until it expires with your passport.
The scenario to avoid is the departure-lounge application. Since the end of February 2026, airlines fully check ETAs at boarding, and on the usual Australia to UK routings that check happens at your first check-in counter in Australia. A last-minute application usually works, because most decisions are automatic, but you cannot control whether yours joins the minority that goes to review, and without a decided ETA you will not board. The probability of a problem is low; the consequence is your whole itinerary. Two narrow notes: travellers transiting airside at Heathrow or Manchester without crossing border control are currently exempt, and anyone who already holds a UK visa or UK eVisa status does not need an ETA at all.

What to do if three working days have passed
Check your spam folder, confirm the application was actually submitted, and do not apply a second time. Decision emails routinely end up in junk folders, so search the inbox you used for the application before assuming anything is wrong. Then confirm you received the submission confirmation email; that is your evidence the application was lodged in the first place. If the confirmation exists but no decision has arrived after three full UK working days, the official route is to contact UK Visas and Immigration, and the guidance asks you to wait out those three days before doing so.
What will not help is lodging a duplicate application. A second application does not jump any queue, official guidance is explicit that no alternative route produces a faster decision, and you would pay a second application fee for the privilege. If your travel date is close and the wait has become a genuine problem, this is a sensible moment for professional review of your situation rather than another submission of the same one.
Can you pay to speed it up? The truth about rush processing
No. There is no priority, premium or express tier for the UK ETA, and official guidance states plainly that you cannot get a faster decision by applying through another website or app. This surprises people, because paid priority services do exist elsewhere in the UK system, including for the visit visa. The ETA is different: every application, however submitted, sits in the same government queue and is decided on the same timeline. Any website advertising one-hour, same-day or rush ETA processing is charging a premium fee on top of a process that runs at exactly the same speed for everyone. You are not buying a faster decision; you are buying a more expensive invoice.
What a legitimate consultancy can offer is accuracy rather than speed. Pre-submission review by OlaVisa's expert team catches errors that trigger automatic rejections, and getting the application right the first time is the only genuine time-saver available. The slowest ETA of all is the one that gets refused, because the fallback is a UK visit visa application with its own documentation and a processing reference of around three weeks.
Frequently asked questions
Can I travel to the UK while my ETA is still processing?
No. You must wait for the email confirming your ETA before travelling, and since the end of February 2026 airlines verify ETAs at boarding. Without a decided application you will be denied boarding at check-in, which on most Australian routings means at your first airport.
Why is my ETA taking longer than my travel companion's?
Decisions are individual, so people who applied minutes apart can hear back hours or days apart. One application being referred for review has no effect on the others in your group, and a longer wait does not signal a refusal.
Does the time of day I apply make a difference?
Not for most people. Automatic decisions arrive around the clock, including on weekends. The working-day reference only really matters for applications that need manual review, and those progress during UK business hours, which fall across the Australian evening and overnight.
Should I apply again if I have not heard back?
No. A duplicate application does not speed anything up and incurs a second fee. Check your spam folder, confirm you received the submission confirmation email, and once three full UK working days have passed, use the official contact route instead.
What happens if my ETA application is refused?
There is no appeal against an ETA refusal. The standard next step is a visit visa application, which involves more documentation and a longer processing timeframe. OlaVisa's Denial Protection means no extra service fees if your application is rejected, so the setback does not compound.
How long does an approved ETA last?
Two years, or until the passport you applied with expires, whichever comes first. It covers multiple visits of up to six months each. Renewing your passport voids the ETA, so you would apply again on the new document.
