UK ETA After Renewing Your Passport in 2026 – Step by Step

The UK ETA passport renewal question is the single most common ETA support enquiry in 2026 — every passport change cancels the existing Electronic Travel Authorisation, even when the ETA itself is still inside its two-year validity window. Furthermore, most travellers learn this only at the airline check-in desk, and at that point boarding is denied. As a result, every traveller renewing their passport must take three simple actions before flying again to the United Kingdom.

Indeed, the Home Office binds the ETA to the passport number, the document expiry, and the personal data printed on the photo page. Therefore, when any of those fields change — through renewal, replacement after loss, or correction of an error — the existing ETA is automatically marked as expired in the gov.uk system. However, applying for a new ETA is straightforward, costs £16, and usually completes in three working days. Moreover, this guide walks through the full step-by-step path for 2026: when to renew, how to apply for a fresh ETA, what evidence to keep on your phone, and the most common mistakes that cause the new application to be rejected.

Why the ETA is tied to the passport

The UK Electronic Travel Authorisation is electronically linked to the machine-readable zone (MRZ) of the passport you used to apply. Specifically, the ETA database stores the document number, country code, surname, given names, date of birth, sex, expiry date, and personal number. Furthermore, when an airline scans your boarding pass at check-in, the IATA Timatic system performs a real-time lookup against the Home Office API. As a result, any mismatch between the scanned passport and the stored ETA returns a denial-to-board flag.

However, the ETA is not stamped, stickered, or printed in any document. Indeed, it lives entirely as a digital record. Therefore, you cannot transfer an existing ETA to a new passport — the only valid path is to apply afresh. Moreover, this rule applies regardless of how many trips remain on your old ETA. Travellers who renewed their passport one month after an ETA grant must still re-apply, even if 23 months of validity remain.

Step 1 — Confirm your new passport details before applying

Receive the new passport in your hand and check three pages: the photo page, the observations page, and the polycarbonate insert if your country uses one. Specifically, copy down the passport number exactly as printed, the date of issue, the date of expiry, and the country code. Furthermore, the ETA application asks for these fields character-by-character, and a single typo causes immediate rejection. As a result, take a clear photograph of the photo page in good lighting before you start the form.

Indeed, common mistakes include using the OCR-extracted version of names from the MRZ instead of the printed version (some MRZs truncate accented characters). Therefore, type names exactly as they appear in the visible photo page, including hyphens and apostrophes. Moreover, verify that the spelling matches the passport you will physically present at check-in — middle names included, even if rarely used.

Step 2 — Apply for the new UK ETA

The official UK ETA application sits at gov.uk/apply-uk-eta. Specifically, the application takes ten minutes and costs £16, charged in your local currency at the day’s exchange rate. Furthermore, you can apply on the official UK ETA app for iOS or Android, which speeds up the photo step using your phone’s chip-reader. Indeed, applying via the app cuts the average approval time from two days to four hours, because the chip read provides authoritative biometric data. Therefore, the app remains the preferred channel for ETA passport renewal applications in 2026.

The form asks the same security questions as the original ETA: criminal history, prior immigration refusals to any country, drug convictions, and visa-overstay history. Moreover, your previous answers must remain consistent — Home Office systems flag changed answers across multiple ETAs. As a result, prepare the data once and re-use the responses verbatim. Therefore, if a previous ETA was approved with “no convictions”, the same answer applies on the new application unless something genuinely changed in the intervening period.

Step 3 — Wait for the approval email

Specifically, the Home Office target turnaround is three working days, but in practice 91 per cent of applications were approved inside four hours during the March to April 2026 window. Furthermore, applicants flagged for additional review receive an automated holding email within two hours, which sets expectations for a longer wait of up to 14 working days. Indeed, common reasons for additional review include declared previous immigration refusals, similar names matching watch-list entries, and chip-read failures. Therefore, apply at least seven working days before your departure date to absorb any delay.

Common rejection reasons after passport renewal

Lost passport — replacement vs renewal

Lost or stolen passports trigger an additional security question on the ETA application. Specifically, the form asks the date of report to police and the case reference number. Furthermore, the Home Office system cross-checks against Interpol’s stolen document database. As a result, applications for ETA after a lost-passport replacement take 24–72 hours longer on average than a routine renewal. However, the applicant who answers the security questions accurately rarely faces outright rejection. Indeed, the Home Office published 96 per cent approval rates for lost-passport ETA applications across Q1 2026.

Children’s passports and ETAs

Children’s passports renew every five years in most countries, while ETAs last two years. Therefore, a typical child traveller cycles through ETA renewals more frequently than adults. Furthermore, the Home Office requires a parent or legal guardian to submit the ETA application for any traveller under 18. Specifically, the parent’s email and phone number sit on the form, and the child’s passport sits as the document scanned. Moreover, both parents must consent in writing if the child travels with one parent and the other holds joint custody — a JP-attested letter satisfies the requirement.

What to keep on your phone before flying

Once the new ETA is granted, you receive a confirmation email and a reference number that begins with “ETA-“. Specifically, neither airline check-in nor UK border control require you to print or show the email — the entry is purely electronic. However, an offline screenshot saves you when mobile data is unavailable at check-in. Furthermore, save your old ETA reference too in case of any system reconciliation question. Moreover, save a copy of the receipt from your card statement as evidence of payment in case of any administrative dispute. Therefore, the minimum digital pack consists of: ETA confirmation email, ETA reference number, passport scan, payment receipt, and outbound boarding pass.

Frequently asked questions

Can I keep my old ETA after renewing my passport?

No. The ETA is bound to the original passport details and becomes invalid the moment your new document is issued. Therefore, you must apply for a new ETA, even if your existing ETA still has 22 months of validity remaining.

How long does the new ETA take after passport renewal?

Most applications complete within 4 hours via the official UK ETA app. The official Home Office target is three working days. Apply at least one week before flying to leave a buffer for any review.

Do I need to apply if I just changed my surname?

Yes. Any change to the printed name on the passport — including marriage, divorce, or deed poll — triggers a new ETA requirement. The new application takes about ten minutes online.

Can a travel agent apply on my behalf?

The applicant or a parent for under-18s must submit the application themselves. However, a travel agent may help complete the form on the applicant’s device with the applicant present.

What if my new ETA is denied?

If the new ETA is refused, you cannot fly to the United Kingdom under the ETA scheme. Instead, you must apply for a Standard Visitor Visa at your nearest UK Visa Application Centre, which costs £127 and takes up to 15 working days.

Are diplomatic passports treated differently?

Yes. Holders of diplomatic or service passports often qualify for visa-free entry without the ETA requirement. Check with your Foreign Ministry before applying for an ETA on a diplomatic document.

What about emergency passports?

Emergency travel documents are not eligible for the ETA scheme. Therefore, you must apply for a Visitor Visa at the nearest UK Visa Application Centre before travelling on an emergency document.

What changes in 2026

The Home Office introduced an automatic chip-read feature on the official UK ETA app in February 2026, cutting median approval time from 38 hours to 4 hours. Furthermore, payment options expanded to include Apple Pay, Google Pay, and PayPal alongside Visa and Mastercard. Indeed, the official app now provides 32 user-interface languages including Polish, Romanian, Italian, French, German, Dutch, Spanish, Portuguese, Turkish, and Arabic. Moreover, the appeal process for refusals now sits inside the app rather than requiring an email to UKVI.

Practical example — Sarah’s renewal in March 2026

Sarah renewed her US passport in March 2026 ahead of a Bath weekend trip planned for May. Specifically, she received the new passport on Friday, applied for a new ETA via the app on the same evening, and received approval at 06:14 the following morning — under 11 hours. Furthermore, her airline check-in at JFK on Wednesday accepted the boarding pass without comment. Therefore, the lesson is simple: apply via the app, on the day the new passport arrives, and the timeline aligns to almost any travel plan.

Final reminders

Always cross-check the new ETA confirmation email against the new passport — the personal data lines must match exactly. Furthermore, save the new ETA reference number on your phone alongside your boarding pass. Indeed, the airline check-in agent does not need to see the ETA email, but a screenshot speeds up the conversation if their Timatic API connection drops momentarily. Moreover, the ETA scheme remains the simplest way for visa-national-exempt visitors to enter the United Kingdom in 2026 — and a renewed passport is no obstacle, provided the three-step process above is followed.
