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. Most travellers only find this out at the check-in desk. By then, boarding is refused. So before you fly to the United Kingdom again, a renewed passport means three simple actions.

The Home Office binds the ETA to the passport number, the document expiry, and the personal data printed on the photo page. When any of those fields change — through renewal, replacement after loss, or correction of an error — the existing authorisation is automatically marked as expired in the gov.uk system. The fix is cheap. A fresh ETA costs £20 and usually clears in three working days. 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 mistakes that most often get the new application 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. The ETA database stores the document number, country code, surname, given names, date of birth, sex, expiry date, and personal number. When an airline scans your boarding pass at the gate, the IATA Timatic system runs a real-time lookup against the Home Office API. Any mismatch between the scanned passport and the stored record returns a denial-to-board flag.

The ETA is not stamped, stickered, or printed in any document. It lives entirely as a digital record. That is why you cannot move an existing ETA onto a new passport — the only valid path is to apply afresh. This rule holds no matter how many trips remain on your old authorisation. Renew your passport one month after an ETA grant and you still re-apply, even with 23 months of validity left.

Step 1 — Confirm your new passport details before applying

Get 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. Copy down the passport number exactly as printed, plus the date of issue, the date of expiry, and the country code. The form asks for these fields character-by-character, and a single typo triggers immediate rejection. Photograph the photo page in good light before you start.

One common mistake is copying names from the OCR-extracted MRZ instead of the printed version — some MRZs truncate accented characters. Type names exactly as they appear on the visible photo page, hyphens and apostrophes included. Then check the spelling against the passport you will physically hand over at the gate, middle names and all, even the ones you rarely use.

Step 2 — Apply for the new UK ETA

The official UK ETA application sits at gov.uk/apply-uk-eta. It takes ten minutes and costs £20, charged in your local currency at the day’s exchange rate. You can also apply through the government’s ETA app for iOS or Android, which speeds up the photo step using your phone’s chip-reader. Reading the chip provides authoritative biometric data, so the app cuts average approval time from two days to four hours. That makes it the preferred channel for 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. Your previous answers must stay consistent — the Home Office flags changed answers across multiple ETAs. Prepare the data once and reuse the responses word for word. If an earlier ETA was approved with “no convictions”, give the same answer now unless something genuinely changed in between.

Step 3 — Wait for the approval email

The official target turnaround is three working days, yet 91 per cent of applications were approved inside four hours during the March to April 2026 window. Applicants flagged for extra review get an automated holding email within two hours, warning of a longer wait of up to 14 working days. Those flags usually trace back to declared previous immigration refusals, similar names matching watch-list entries, or chip-read failures. Apply at least seven working days before departure to absorb any delay.

Common rejection reasons after passport renewal

Lost passport — replacement vs renewal

Lost or stolen passports trigger an extra security question on the ETA application. The form asks for the date you reported it to police and the case reference number. Behind the scenes, the system cross-checks Interpol’s stolen document database. Because of that, an ETA after a lost-passport replacement takes 24–72 hours longer on average than a routine renewal. Answer the security questions accurately and outright rejection is rare — the Home Office published a 96 per cent approval rate 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. So a typical child traveller cycles through ETA renewals more often than adults. A parent or legal guardian must submit the application for any traveller under 18. The parent’s email and phone number go on the form, and the child’s passport is the document scanned. If the child travels with one parent while the other holds joint custody, both must consent in writing — a JP-attested letter satisfies the requirement.

What to keep on your phone before flying

Once your new ETA comes through, you receive a confirmation email and a reference number starting with “ETA-“. Neither the check-in desk nor UK border control needs you to print or show the email — the entry is purely electronic. Still, an offline screenshot saves you when mobile data drops at the gate. Keep your old ETA reference too, in case a system reconciliation question comes up. Save the receipt from your card statement as proof of payment for any administrative dispute. The minimum digital pack: 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 £135 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

In February 2026 the Home Office added an automatic chip-read feature to the ETA app, cutting median approval time from 38 hours to 4 hours. Payment options widened too — Apple Pay, Google Pay, and PayPal now join Visa and Mastercard. The app carries 32 user-interface languages, including Polish, Romanian, Italian, French, German, Dutch, Spanish, Portuguese, Turkish, and Arabic. And the appeal process for refusals now lives inside the app instead of 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. The passport arrived on Friday. She applied for a fresh ETA through the app that same evening and had approval at 06:14 the next morning — under 11 hours. Her check-in at JFK on Wednesday accepted the boarding pass without comment. The lesson is simple: apply via the app the day the new passport lands, and the timeline fits 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. Save the ETA reference number on your phone alongside your boarding pass. The check-in agent does not need to see the ETA email, but a screenshot speeds things up if their Timatic connection drops for a moment. For visa-national-exempt visitors, the ETA scheme stays the simplest way into the United Kingdom in 2026 — and a renewed passport is no obstacle, as long as you follow the three steps above.
