10 Common UK ETA Application Mistakes to Avoid in 2026

Introduction

Applying for a UK Electronic Travel Authorisation might seem straightforward, but thousands of applications face delays or rejections every month due to avoidable mistakes. This guide highlights the 10 most frequent UK ETA application mistakes in 2026.

Mistake 1: Submitting with an Expiring Passport

Many applicants submit applications with passports about to expire. If your passport expires during your ETA's 2-year validity period, the authorization becomes invalid immediately.

Solution: Ensure your passport has at least 2 years of validity remaining before applying.

Mistake 2: Poor Quality Photographs

Photograph rejections are among the most common reasons for UK ETA delays. Photos are often too old, have incorrect backgrounds, or show the person wearing glasses or hats.

Solution: Take a fresh photograph meeting all UK requirements: plain background, taken within 6 months, full face visible, no glasses or headwear.

Mistake 3: Spelling Errors in Personal Information

Simple typos in names, passport numbers, or other personal details cause automatic rejections. Since the UK ETA is electronically linked to your passport, even minor discrepancies trigger red flags.

Solution: Enter information exactly as it appears on your passport and have someone review your application before submission.

Mistake 4: Applying Too Close to Travel Date

Many travelers apply just days before their flight, assuming instant approval. While most applications are processed within 72 hours, complications can arise.

Solution: Apply at least 2 weeks before your intended travel date to allow time for processing and potential issues.

Mistake 5: Inconsistent Travel Information

Applicants sometimes provide vague or inconsistent travel details, such as stating tourism but listing a business address.

Solution: Be specific and consistent. Provide hotel names for tourism, company details for business, and contact information when visiting family.

Mistake 6: Not Disclosing Previous Immigration Issues

Some applicants fail to disclose previous visa rejections or overstays. Immigration databases are interconnected, and false information leads to automatic rejection.

Solution: Answer all questions truthfully, including previous visa rejections, overstays, deportations, and criminal convictions.

Mistake 7: Using Incorrect Payment Methods

Payment failures cause delays. Common issues include cards without international capability, insufficient funds, or prepaid cards that get declined.

Solution: Use a standard credit or debit card from a major bank with international transaction capability and sufficient funds.

Mistake 8: Applying for Wrong Authorization Type

Some applicants confuse UK ETA with traditional visas or other travel authorizations.

Solution: Verify your eligibility for UK ETA. If you need to work, study long-term, or stay beyond 6 months, you need a visa, not an ETA.

Mistake 9: Ignoring Email Requests for Additional Information

UK immigration may request additional documentation. Many applicants miss these emails or respond too late.

Solution: Check your email regularly, including spam folders, and respond promptly to any requests within the specified timeframe.

Mistake 10: Not Keeping Application Records

Some travelers lose their approval confirmation and have no reference number when issues arise at the airport.

Solution: Save your approval email, take screenshots, and store your reference number in multiple places including phone and cloud storage.

Conclusion

Avoiding these common mistakes significantly increases your chances of quick UK ETA approval. Take your time, double-check all information, and apply well in advance of your travel date.
