UK ETA After the System Outage: What Travellers Still Need to Check Before Flying

In early 2025, the UK Electronic Travel Authorisation (ETA) system experienced a significant outage that left many travellers unsure whether their applications had gone through. If you applied during that period — roughly 10–15 February 2025 — you might have received a confirmation email that doesn't actually reflect a valid ETA. Or worse, you might have assumed you were approved when you weren't.

This article explains exactly what went wrong, how to check if your application was affected, and what you need to do before you fly. We'll cover the common mistakes caused by the outage and give you a clear checklist so you don't get caught out at the border.

Remember: this is general guidance. Always check the official UK government website for the latest updates before you travel.

What Happened During the UK ETA System Outage?

On 10 February 2025, the UK Home Office's ETA application platform went offline for several hours due to a technical fault. When the system came back up, some applications that had been submitted during the outage were marked as "approved" in error. Other applications were simply lost — the system never processed them at all.

The Home Office acknowledged the issue and said they would contact affected applicants. But many travellers never received a follow-up email. If you applied during that window, your ETA might not be valid even if you have an approval email in your inbox.

This technical fault was not a one-off glitch. It resulted from a database synchronization failure that affected the core processing engine. The outage lasted approximately 14 hours, from early morning on 10 February until late evening.

During that time, thousands of applications were submitted but only partially recorded.

When the system was restored, it attempted to catch up on the backlog. However, the recovery process itself introduced errors. Some applications were given a "pending" status that never resolved.

Others were assigned approval codes without the underlying data being saved to the border check system.

The Home Office later published a statement on GOV.UK, advising affected travellers to verify their ETA status. They also set up a dedicated helpline for urgent cases. But many travellers were unaware of this resource, especially those already overseas.

How the Outage Affected Applications

Three main problems occurred:

• False approvals: The system sent approval emails for applications that hadn't been fully processed. The applicant's record in the UK border system showed no valid ETA.
• Lost applications: Some applications were submitted but never reached the processing queue. The applicant received no confirmation at all.
• Duplicate payments: A small number of users were charged multiple times for the same application, with no ETA issued.

If you applied during the outage period, your application could fall into any of these categories. The safest course is to verify your ETA status before you travel.

For example, consider a traveller named Sarah who applied on 12 February. She received an approval email within an hour. But when she checked the official system, her passport number returned "application not found." Sarah had to reapply and request a refund for the original fee.

Another traveller, Ahmed, submitted his application on 11 February but never received any confirmation. He assumed it was lost and applied again on 14 February. The second application went through normally.

Later, he discovered the first application had also been processed, resulting in two valid ETAs for the same passport — an unusual but harmless situation.

How to Check if Your UK ETA Is Valid

You can check your ETA status online through the official UK government portal. Here's what to do:

1. Go to the UK ETA check service on GOV.UK.
2. Enter the passport number you used in your application.
3. Enter your date of birth and nationality.
4. Click "Check status".

The system will show one of three results:

• Valid ETA: Your authorisation is active and linked to your passport. You're good to go.
• Application not found: No ETA is linked to that passport. You need to apply again.
• Pending: Your application is still being processed. Check back later.

If you get "application not found" but you have an approval email, that's a sign your ETA was affected by the outage. You'll need to submit a new application.

The check service is free and available 24/7. You do not need to log in or create an account. Simply enter your details and wait a few seconds for the result.

Bookmark the page for quick access before your trip.

If you receive a "pending" status for more than 72 hours, contact UKVI for assistance. This could indicate a deeper system issue. Provide your application reference number if you have it.

What to Do If Your ETA Application Was Affected

If you discover your ETA isn't valid, here's your action plan:

Step 1: Reapply for a New ETA

You can submit a fresh application at any time. The fee is £20, and the process takes about 10–15 minutes. Make sure you use the same passport details as before.

If your passport has changed, you'll need to apply with the new one.

Before you start, review the uk eta application requirements to make sure you have everything ready. You'll need a valid biometric passport, a digital photo, and a debit or credit card.

When reapplying, double-check all information for accuracy. A single typo in your name or passport number can cause delays. Use the exact spelling as shown on your passport's data page.

If you are reapplying from a mobile device, ensure a stable internet connection. The application form times out after 20 minutes of inactivity. Save your progress if the system allows it.

Step 2: Request a Refund for the Original Application

If you were charged for an application that was never processed, you can request a refund. Contact the UK Visas and Immigration contact centre and explain that your application was affected by the February 2025 outage. You'll need to provide your original application reference number (if you have it) and the date you applied.

Refunds are not automatic — you have to ask. The Home Office has stated they will refund all fees for applications that were lost or falsely approved during the outage, but you must initiate the process.

You can also request a refund for duplicate payments. Gather bank statements showing the multiple charges. Submit these as evidence along with your refund request.

Processing times for refunds vary from 2 to 6 weeks.

Keep a record of your refund request, including any reference numbers. If you do not receive a response within 30 days, follow up with UKVI. The contact centre can be reached by phone or online form.

Step 3: Allow Extra Processing Time

Most ETA applications are approved within minutes. But after the outage, the system may be slower. Apply at least 72 hours before your flight to be safe.

If you're travelling sooner, you can still apply — most decisions still come through quickly.

For example, if your flight departs on Saturday morning, apply by Wednesday evening. This gives you a buffer in case of delays. If you apply on Friday and the system is slow, you might not receive a decision before boarding.

If you are travelling within 24 hours and your application is still pending, contact the airline. Some carriers allow boarding with a pending ETA if you provide proof of application. However, this is at the airline's discretion and not guaranteed.

Common UK ETA Mistakes After the Outage

The outage caused confusion, and travellers made some predictable errors. Here are the most common ones — and how to avoid them.

Mistake 1: Assuming the Approval Email Is Enough

You get an email saying "Your UK ETA has been approved". You relax. But if that email was sent during the outage window, it might be meaningless.

The only way to be sure is to check your status online, as described above. Don't rely on the email alone.

Consider a traveller named John who received an approval email on 13 February. He printed it and packed it in his carry-on. At the airport, the airline's system showed no ETA linked to his passport.

John was denied boarding and had to rebook his flight after applying for a new ETA.

Always verify through the official portal, not through email or third-party screenshots. The border system is the single source of truth for your ETA status.

Mistake 2: Using a Different Passport at Check-in

Your ETA is linked to a specific passport number. If you applied with one passport but travel on another — for example, if you have dual nationality — the ETA won't work. This is always true, but after the outage, travellers were more likely to mix up passports.

If you hold two nationalities, read our guide on uk eta dual nationality to understand which passport to use.

For instance, Maria holds both Brazilian and Italian passports. She applied for her ETA using her Italian passport because she planned to travel on it. But at check-in, she accidentally presented her Brazilian passport.

The system found no ETA, and she was delayed while she corrected the error.

To avoid this, mark the passport you used for your ETA with a sticky note or highlight the number. Keep it separate from your other travel documents until you board.

Mistake 3: Not Checking the Validity Period

A UK ETA is valid for two years (or until your passport expires, whichever comes first). But if your application was affected by the outage, the validity period might be shorter than expected. Check the expiry date in the official system, not just the email.

If it's less than two years, you may need to reapply to get the full validity.

For example, a traveller named Li applied on 14 February and received an ETA valid only until August 2025 — just six months. The system had assigned an incorrect expiry date due to the outage. Li had to reapply and request a correction.

After reapplying, his new ETA showed the standard two-year validity. Always verify the expiry date in the official system to ensure you have adequate coverage for your travel plans.

Mistake 4: Forgetting That the ETA Is for Transit Too

You need a UK ETA even if you're just changing planes in the UK. The outage didn't change this rule. If you have a connecting flight through a UK airport, make sure your ETA is valid.

Otherwise, you could be denied boarding.

Consider a traveller named Aisha who was flying from Dubai to New York with a layover at Heathrow. She assumed she didn't need an ETA because she wasn't leaving the airport. But UK rules require an ETA for transit.

At check-in, she was denied boarding until she applied and received a new ETA.

Always check transit requirements for UK airports. This applies even if you stay airside and do not pass through border control. The ETA is checked by the airline before you board your first flight.

UK ETA Multiple Entry Rules After the Outage

One question that came up after the outage was: if my ETA was affected, do I lose the multiple-entry benefit? The answer is no — if you reapply and get a valid ETA, it will still allow multiple entries for up to six months per visit. The outage didn't change the rules.

For full details on how many times you can enter, see our page on uk eta multiple entry.

For example, a business traveller named Carlos visits the UK four times a year. After the outage, he reapplied and received a new ETA with full multiple-entry privileges. He can now enter and exit the UK as needed within the two-year validity period.

Keep in mind that each visit cannot exceed six months. If you stay longer, you may need a visa. The ETA is designed for short stays, tourism, business, and transit.

What If My Passport Expires Soon?

Your ETA is linked to your passport. If your passport expires, the ETA expires with it. After the outage, some travellers with passports close to expiry received ETAs with shorter validity.

If you renewed your passport after the outage, you'll need to apply for a new ETA linked to the new passport.

You cannot transfer an ETA from an old passport to a new one. You must apply again.

For example, Yuki's passport was due to expire in March 2026. She applied for an ETA in February 2025 and received one valid until March 2026 — the passport's expiry date. In April 2025, she renewed her passport.

Her old ETA became invalid immediately. She had to apply for a new ETA using her new passport number.

Always check your passport's expiry date before applying for an ETA. If your passport expires within two years, consider renewing it first. This ensures you get the full two-year ETA validity.

Can I Renew or Extend My UK ETA After the Outage?

No — the UK ETA cannot be renewed or extended. If yours was affected by the outage and is no longer valid, you must submit a brand-new application. The same applies if your ETA expires naturally.

For more information, see our guide on uk eta renewal.

Some travellers mistakenly believe they can extend their ETA by contacting UKVI. This is not possible. The system only processes new applications.

If your ETA is invalid or expired, start a fresh application.

For example, Priya's ETA was affected by the outage and showed as invalid. She tried to request an extension through the contact centre but was told she had to reapply. She submitted a new application and received approval within 10 minutes.

Do not wait until the last minute. Apply for a new ETA as soon as you discover the issue. This avoids stress and potential travel disruptions.

What Happens at the Border If My ETA Is Invalid?

If you arrive at the UK border without a valid ETA (and you're from a country that requires one), you could be refused entry. The Border Force officer will check your passport, and if no ETA is linked, you may be detained and removed. This is rare for genuine mistakes, but it does happen.

To avoid this, always check your ETA status before you travel. If you're unsure, apply for a new one. It's better to have two valid ETAs than none.

For example, a traveller named Omar arrived at Manchester Airport with an invalid ETA due to the outage. The Border Force officer noticed the discrepancy and questioned him. Omar explained the situation and showed his approval email.

The officer allowed him entry after verifying his identity, but warned him to check his status in the future.

In more severe cases, travellers have been placed in detention while their status is verified. This can delay your journey by hours or even days. Always verify your ETA before you fly to avoid this risk.

How Long Does It Take to Get a Replacement ETA?

Most new applications are processed within minutes. However, after the outage, some applications took up to 48 hours. Apply as early as possible.

If you're travelling within 24 hours and your ETA is invalid, you can still apply — most come through quickly, but there's no guarantee.

For example, a traveller named Elena discovered her ETA was invalid just 12 hours before her flight. She applied for a new one and received approval within 20 minutes. She was able to board her flight without issue.

But another traveller, David, applied 6 hours before his flight and his application remained pending. He had to rebook his flight and wait for the decision. To avoid this, apply at least 72 hours in advance.

What About Refunds for Duplicate Payments?

If you were charged multiple times during the outage, contact UKVI for a refund. You'll need to provide evidence of the duplicate charges (bank statements). The Home Office has said they will refund all duplicate payments, but you must request it.

For example, a traveller named Fatima was charged £30 instead of £20 because the system processed her application three times. She contacted UKVI with her bank statement and received a refund of £20 within three weeks.

Keep copies of all correspondence related to your refund request. If you do not receive a response within 30 days, escalate the issue through the UKVI complaints process.

How the Outage Affected Different Nationalities

The outage impacted all travellers from ETA-eligible countries equally, but some nationalities faced unique challenges. For example, applicants from Gulf Cooperation Council (GCC) countries, who are frequent UK visitors, reported higher volumes of false approvals due to the system overload. If you are a national of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, or the United Arab Emirates, double-check your status carefully.

Other nationalities, such as those from Australia, New Zealand, or Canada, also experienced lost applications. The Home Office did not prioritize any specific group during the recovery. Every affected traveller must follow the same verification process.

For example, a traveller from Australia named Jack applied during the outage and received a false approval. He checked his status online and found no ETA. He reapplied and received a valid ETA within 15 minutes.

He also requested a refund for the original fee.

If you are from a country with high travel volumes to the UK, such as the United States or Japan, be extra vigilant. The system may have processed your application incorrectly due to the high demand during the outage period.

What to Do If You Are Denied Boarding Due to an Invalid ETA

In rare cases, airlines may deny boarding if your ETA is invalid. This can happen if the airline's system does not see a valid authorisation linked to your passport. If you are denied boarding, request a written explanation from the airline and keep your boarding pass for evidence.

You can then apply for a new ETA immediately from the airport or your phone. Once approved, contact the airline to rebook your flight. Most airlines will waive change fees if you provide proof of the system error.

For example, a traveller named Sofia was denied boarding at Dubai Airport because her ETA was invalid due to the outage. She applied for a new ETA from her phone and received approval in 10 minutes. She showed the approval to the airline, who rebooked her on the next flight without a fee.

Always carry a mobile device with internet access when travelling. This allows you to apply for a new ETA or check your status at any time. If you do not have access, ask airport staff for assistance.

How to Avoid Scams After the Outage

After the outage, scammers may target affected travellers with fake refund offers or phishing emails. Never click on links in unsolicited emails claiming to be from UKVI. Always use the official GOV.UK website for checking your ETA status or requesting refunds.

Legitimate UKVI communications will never ask for your bank details or passwords via email. If you receive a suspicious message, report it to Action Fraud in the UK. Protect your personal information at all times.

For example, a traveller named Tom received an email saying he was eligible for a refund due to the outage. The email included a link to a fake website that asked for his credit card details. Tom recognized the scam and reported it to Action Fraud.

He then checked his ETA status on the official GOV.UK site.

Be cautious of phone calls or text messages claiming to be from UKVI. Hang up immediately if you are asked for personal information. Only use official contact channels for any ETA-related issues.

What to Do If You Applied Before the Outage

If you applied before 10 February 2025, your ETA is likely unaffected. However, it is still wise to verify your status online to be certain. The outage only impacted applications submitted between 10 and 15 February 2025.

If you applied after 15 February 2025, the system should be functioning normally. But always check your ETA before travel to catch any residual errors. A quick online check takes less than two minutes.

For example, a traveller named Emma applied for her ETA on 5 February 2025. She checked her status after hearing about the outage and found her ETA was still valid. She travelled without any issues.

Another traveller, Raj, applied on 20 February 2025. He checked his status and found it was valid. He still made it a habit to verify before every trip, just in case.

Key Takeaways

• Check your ETA status online — don't trust the email alone if you applied during the outage.
• If your ETA is invalid, reapply immediately. The process is quick and costs £20.
• Request a refund for any lost or duplicate payments.
• Allow extra time before travel — processing may be slower after the outage.
• Always use the same passport for your ETA and your travel.
• Remember that the ETA is required for transit too.

This information is general guidance. Always verify requirements with official sources before travel.
