How Long Does a UK ETA Take? Processing Times, Delays and What to Do

Picture the usual scenario. A flight is booked for next Friday, the passport is in a drawer, and someone mentions that a UK ETA is now required. The obvious question is how long a UK ETA takes, and whether it is something to finish tonight or something that can wait until the weekend. The honest answer is that many decisions are quick, you should still leave room for up to three working days, and the applications that run into trouble are mostly the ones left to the last minute.

This guide sets out what to expect on timing as of 7 October 2026, explains what can slow an application down, and walks through what to do if you are still waiting. It also covers a question that matters just as much as speed: what an approval does and does not mean once you have it.

Two clocks: preparing and deciding

Two separate clocks run during an ETA application, and mixing them up is the source of most confusion about timing.

• Preparation and submission. This is the time it takes to gather the passport details, photo and email address, complete the application accurately and submit it. This part is largely in the applicant’s hands, or in the hands of whoever is helping to prepare the application.
• The decision. This is made by the UK immigration authorities, who assess each application and decide whether to grant an ETA. The time it takes is theirs, not the applicant’s and not any assistance provider’s.

A service that helps with an application can influence the first clock by helping you prepare and submit an accurate application promptly. It cannot control the second. Nobody outside the immigration authorities can promise how quickly a decision will be made, or what it will be.

You must also wait for the email that confirms you hold an ETA before you travel. An application in progress gives you nothing to show at check-in, however quickly it was submitted.

How long does a UK ETA take in practice?

Many applicants receive a decision by email within about a day. Some decisions take longer, and applicants should allow up to three working days. For planning, the useful number is the longer one. A traveller who has to be at the airport in two days cannot rely on “within a day”, because three working days is the outer allowance.

Working days are the key phrase. An application submitted late on a Friday may not reach three working days until the following Wednesday, and public holidays stretch that further.

It also helps to separate three different things that people tend to blur together:

• The time to complete the application. With the passport, email address, photo and payment method ready, it is a short task. Without them it can stretch across several sessions.
• The time to a decision. This is set by the immigration authorities, as described above.
• The time to confirmation in your hands. This depends on whether you can see the email. A decision that landed in a junk folder or an old inbox is, for your purposes, still a delay.

A timeline from submission to day three

The table below translates the typical pattern into practical steps. It does not promise any particular outcome; the checkpoints simply follow the stages most applications pass through.

Why timings vary

One application is decided in minutes while another takes days. Nobody outside the decision process can say exactly why in a given case, but several factors are well understood.

Not every application is decided immediately. The gap between “often within a day” and “allow up to three working days” exists because some applications take longer than others, including those that need additional review. You cannot predict from the outside which ones will.

Photo quality can cause delay or rejection. A face photo that does not meet the required standards may delay the application or cause it to be rejected. That is one of the few causes the applicant can control.

Applications for several people can be decided separately. Where one person applies for several travellers, decisions for different people may arrive at different times. A family should not assume that three approvals will land together, or that one decision means the others are done.

Suitability checks apply to every application. The Immigration Rules allow an ETA to be refused on grounds such as criminality, previous immigration breaches or false information. How those checks affect the time a decision takes is not published in detail.

What the decision email means

The email is the record. If it confirms that you have an ETA, it is linked to the passport you used and you can travel on it within its validity. If the application is rejected, you will generally need to apply again. Keep the email in more than one place, for example in your inbox and as a screenshot or PDF.

Because the ETA is linked to a passport and not to a document you carry, the passport you applied with is what ties everything together later. Keep the confirmation email, the passport number you used and the email address on the application together, so that you can answer questions about the application if one arises. A pending application cannot be treated as an ETA, so the confirmation email, not the submission screen, is your proof.

Errors that cause delay or rejection

Speed is partly out of your hands, but accuracy is not. These are the mistakes most likely to turn a quick process into a slow one:

• A typo in the email address. The decision goes to the address on the form. If it is wrong, you may never see it.
• A passport detail that does not match the document. The ETA is linked to the passport, so the details must match exactly.
• A face photo outside the standards. Poor lighting, filters, shadows and obscured features all risk delay.
• Applying with a passport you will not use. A decision on the wrong passport helps nobody.
• Choosing the wrong nationality or details for someone you apply for. Check each traveller’s information separately.

If your application is rejected, or you need to change the details in it, you will generally need to apply again. The preparation points in our guide to UK ETA requirements are written to avoid exactly this.

If no decision arrives after three working days

The sensible sequence is short. Follow it in order:

1. Check the junk or spam folder of the email address on the application. Decision emails can be filtered.
2. Check you are looking in the right account. It is easy to look at a personal inbox when the application used a work address.
3. Remember that a pending application cannot be verified as an ETA. Only a granted ETA can be confirmed against the passport it is linked to, so an absence of results does not tell you where your application stands.
4. Contact the right party. If an assistance service prepared and submitted your application, start with that service, which can confirm what was submitted and when. Otherwise, contact UK Visas and Immigration, which handles ETA enquiries, with your application details ready.

Why you should not apply twice

Waiting is stressful, and a second application can look like a way to nudge the first. It is not. A fresh application is normally appropriate in only two cases: the application was rejected, or you need to change the details in it. A pending application is not a reason to submit another.

There is a practical cost too. Each application carries its own charges, and two applications for the same person double the cost without adding any chance of an earlier decision. They can also leave you with two emails to reconcile just before a flight. If you suspect a problem with a pending application, such as a wrong passport detail, raise it through the enquiry route before submitting anything new.

What can and cannot be sped up

The decision itself cannot be bought, bargained for or sped up by anyone outside the immigration authorities. It is made through their own process, and the time it takes does not depend on who prepared or submitted the application.

What can change is everything before and around the decision. A well-prepared application avoids the delays that come from poor photos, mismatched details and unreadable emails. Submitting promptly starts the decision clock sooner. Keeping track of the confirmation email avoids the delay that comes from simply not seeing it. Be cautious about any wording that promises same-day approval, instant results or guaranteed turnaround times for the decision, because no assistance provider can honestly guarantee what the authorities will decide or when.

The same applies to any assistance service UKETA.sg may offer in future. It would help with preparation and submission, and the decision and its timing would remain with the UK immigration authorities. Our fees and processing options page explains how its planned handling times relate to the decision.

Planning backwards from your travel date

A sensible rule is to work back from the date you must travel and leave more room than the minimum. The following examples show how that works without pretending to certainty.

The booked holiday

Someone books flights three months ahead. There is no benefit in waiting. Applying a few weeks before travel leaves time to fix problems, and the ETA, valid for two years, will cover the trip. Applying very early is possible, but remember that the ETA ends when the passport does, so check the passport’s expiry date first.

The short-notice business trip

A manager is asked to attend a meeting in London in four days. Four calendar days may be fewer than four working days if a weekend intervenes. They should apply immediately with the passport at hand, and hold off on non-refundable commitments until the confirmation email arrives. Our guide to UK ETA for business visits describes what such a trip may include.

The family trip

Parents applying for several people should expect decisions to arrive separately and should keep track of each traveller. A child’s ETA is as necessary as an adult’s. If the departure date is close, apply for everyone at the same time and check every inbox you used.

The creative or paid engagement

Travellers coming for a permitted paid engagement, or under the Creative Worker concession, often have fixed dates set by a host or sponsor. The ETA is only one of several documents. Our guides to permitted paid engagements and the Creative Worker concession explain what else you may need, and these travellers should apply for the ETA early so that any problem surfaces well before the event.

After approval: validity and entry

An approved ETA lasts for two years, or until the linked passport expires if that is sooner. It is tied to the passport you used. If you get a new passport, you must apply for a new ETA. During its validity you can make multiple trips, each allowing you to seek entry for up to six months.

It helps to be clear about what an approval does not do. An ETA does not guarantee entry to the UK. Border officers still assess every arrival, and they may ask about your travel plans. Approval means you have permission to travel and seek entry. It is not an assurance of admission. Keep your accommodation details, return or onward travel plans, and any invitation to hand, as our FAQ explains.

When a visa may be the better route

Speed worries are sometimes a symptom of a bigger problem: the ETA may not be the right route at all. Consider a visa instead in situations such as these:

• Your nationality is not eligible for an ETA. Other nationalities cannot get one, and those travellers need to look at visa requirements.
• Your purpose of travel is outside what an ETA covers, such as most work, or marriage or civil partnership, which needs a Marriage Visitor visa.
• You have a criminal record or a previous refusal. In such cases you may want to consider a Standard Visitor visa, because an ETA does not guarantee entry.
• You intend to stay longer than six months.

For the full comparison, read our guide to UK ETA vs UK visa, and our UK visa overview for the main visa routes. Visa timings and processes differ from ETA timings, so check the requirements for the route you need before you set dates.

The practical lesson of this guide is simple: use three working days as your planning ceiling, apply with accurate details, and treat the confirmation email as the starting gun for travel, not the submission screen.
