UK ETA Processing Time: How Long Does It Really Take?

Last updated: 19 October 2026

How Long Does UK ETA Processing Really Take?

If you have just submitted your UK ETA application, you are probably wondering how long it will take to receive a decision. GOV.UK says you will usually get a decision by email within a day, but it can take up to 3 working days. According to the Home Office, most applicants who use the UK ETA app get an automatic decision within minutes.

In this guide, we break down what to actually expect based on real traveller experiences, explain what causes delays, and tell you what to do if your application takes longer than expected.

Official Processing Time: Up to 3 Working Days

GOV.UK says you will usually get a decision within a day, but it can take up to 3 working days, and applications that need additional checks may take longer. Because this is working days rather than 72 hours, weekends and bank holidays do not count.

If you apply on a Friday evening, for example, the 3 working day clock starts on Monday morning. Your application could potentially take until Wednesday evening to be processed under the official timeline.

However, the official processing time is a worst-case scenario for the vast majority of applicants. The system is highly automated, and straightforward applications are processed much faster.

Real Processing Times: What Travellers Actually Experience

Here is how decision times typically break down, based on Home Office guidance:

Minutes (Most Common)

According to the Home Office, most applicants who use the UK ETA app get an automatic decision within minutes. There is no official figure for an exact window. This is because the system runs automated checks against databases, and if everything matches cleanly, approval is instant.

A Few Hours

Some decisions take a few hours. GOV.UK says you will usually get a decision by email within a day, so waiting a few hours is normal and does not mean there is a problem.

1 to 3 Working Days

A smaller number of applications take the full 1 to 3 working days. These are typically cases where the application has been flagged for manual review. This does not necessarily mean anything is wrong. It can simply mean that the automated system wants a human to verify something.

More Than 3 Working Days (Rare)

In rare cases, applications can take longer than the stated 3 working days. This is unusual and typically indicates that additional security checks are being carried out or that there is an issue with the application that needs resolution.

What Causes Delays in ETA Processing?

If your ETA application is taking longer than expected, one or more of the following factors may be responsible:

Name Matching Issues

If your identity cannot be confirmed automatically, your application is passed to a caseworker for manual review. This is a routine check and does not mean you are suspected of anything.

Criminal Record Checks

The application asks whether you have any criminal convictions. If you answer yes, or if background checks reveal a record, additional review time is needed. Even minor or old convictions can trigger a manual check.

Photo Quality Issues

If the photo you submitted does not meet requirements, your application may be held while a caseworker checks it, or it may be rejected – in which case you need to make a new application and pay the £20 fee again. Common issues include poor lighting, incorrect background colour, and photos where the face is not clearly visible.

For help with photos, see our UK ETA Photo Requirements Guide.

Passport Data Discrepancies

If the information you entered does not exactly match what is recorded in the passport database, this can cause delays. Even small differences in how your name is spelled or how dates are formatted can trigger additional verification.

Previous Immigration History

If you have previously been refused entry to the UK, overstayed a visa, or had immigration issues in other countries that share data with the UK, your application may be passed to a caseworker for manual review. Some past breaches, such as overstaying, can be grounds for refusal rather than just a reason for extra checks.

High Application Volume

During peak travel seasons, particularly around summer holidays, Christmas, and major events, the volume of applications increases. While the system is designed to handle large volumes, processing times may be slightly longer during these periods.

What to Do If Your ETA Takes More Than 3 Working Days

If you have waited longer than 3 working days and have not received a decision, here are the steps you should take:

Step 1: Check Your Email Thoroughly

Search your spam and junk folders. ETA approval emails sometimes end up there, especially if your email provider is aggressive with filtering. Search for emails from the UK government or Home Office.

Step 2: Check Your ETA Status Online

You can use the free GOV.UK Check your ETA service to see whether you have a valid ETA and when it expires. There is no step-by-step status tracker, and the UK ETA app does not store your application once it has been submitted – the decision is sent to you by email.

For a step-by-step guide, see how to check your UK ETA status online.

Step 3: Contact UKVI

If your application has been pending for more than 3 working days with no update, you can contact UK Visas and Immigration (UKVI) for assistance:

• UKVI webchat: Available on the GOV.UK website. This is the only UKVI contact channel for ETA enquiries – a digital assistant answers first, and you will need your 16-digit ETA reference number.
• No phone or email support: UKVI cannot help with ETA enquiries by phone or email, so use the webchat.

When contacting UKVI, have your application reference number and passport details ready.

Step 4: Do Not Submit a Duplicate Application

If your application is still being processed, do not submit a second application. Duplicate applications can cause confusion in the system and may further delay your original application. Wait for the current application to be resolved before taking any additional action.

When Should You Apply for Your UK ETA?

The Home Office recommends applying at least 3 working days before you travel. Given that most applications are processed quickly but some can take several days, we recommend the following timeline:

• Ideal: Apply at least 2 to 4 weeks before your planned travel date. This gives you ample time to deal with any delays or issues.
• Acceptable: Apply at least 1 week before travel. This is cutting it close but should be sufficient for most applications.
• Risky: Applying less than 3 days before travel. While most applications are approved quickly, if yours is flagged for manual review, you may not have your ETA in time.
• Last resort: Applying the day before or day of travel. This is not recommended. If your application is not approved in time, you will not be allowed to board your flight.

The ETA is valid for 2 years, or until your passport expires if that is sooner, so there is no disadvantage to applying early. Even if your travel plans change, you can use the same ETA for a future trip as long as it remains valid.

Does It Matter When You Apply During the Day?

There is no official guidance on whether application time affects processing speed. However, some travellers report that applications submitted during UK business hours (Monday to Friday, 9 AM to 5 PM GMT) are processed faster than those submitted late at night or on weekends.

This makes sense given that manual reviews are likely handled during business hours. If your application requires automated checks only, the time of day should not matter.

Real Traveller Experiences

Here is what to expect in practice:

• Most applicants describe the process as surprisingly fast, with many receiving approval within minutes.
• Families applying for several ETAs at once may get decisions at different times, because every traveller, including infants, has a separate application that is checked individually.
• Some applications are passed to a caseworker for manual review – for example, if your identity cannot be verified automatically – and these can take longer.
• If you have not received a decision after 3 working days, check your spam or junk folder before contacting UKVI via its webchat.
• Photos that do not meet the rules and details that do not match the passport are the causes of delay highlighted in official guidance.

Frequently Asked Questions

How long does it take to get a UK ETA?

You will usually get a decision by email within a day, but it can take up to 3 working days. Apply at least 3 working days before you travel, as there is no fast-track service.

Will I definitely get my ETA within 3 working days?

The Home Office aims to process all applications within 3 working days, but this is not a guarantee. In rare cases, applications can take longer due to additional security checks or application issues.

Can I pay for faster processing?

No. There is no expedited or priority processing option for UK ETA applications. All applications are processed in the same queue at the same cost of £20.

What if my flight is tomorrow and my ETA is not approved?

If your ETA has not been approved and your flight is imminent, you will likely not be allowed to board. Airlines are required to check ETA status before allowing passengers to fly. There is no way to fast-track a decision, and UKVI’s webchat can only help once 3 working days have passed since you applied.

Does applying through the app vs the website affect processing time?

No. The processing time is the same regardless of whether you apply through the UK ETA app or the GOV.UK website. The backend processing system is identical.

My ETA was approved instantly but my partner’s is still pending. Is something wrong?

Not necessarily. Different applications can be flagged for different levels of review. If your partner’s application is still within the 3 working day window, there is no cause for concern. The system processes each application individually.

Can I travel while my ETA is still being processed?

No. You must have an approved ETA before travelling to the UK. Airlines will check your ETA status before allowing you to board, and you will be denied boarding if your ETA is not approved.

Key Takeaways
