If you renewed your US passport in 2026 and already had a UK ETA tied to the old book number, you must re-apply. Indeed, the ETA US renewed rule is automatic—an ETA is bound to a specific passport number, and UK border systems reject boarding when the numbers no longer match. Here you’ll find the exact re-apply steps, the refund situation, and the timing for Americans flying to London in May or June 2026.
Why a new passport breaks your existing ETA
The UK ETA scheme uses passport-number lookup at boarding, not facial biometric matching at the airport gate. Specifically, when a US citizen renews their passport (typically every 10 years), the replacement passport carries a different document number—commonly starting “5” or “C” rather than “4” or “9” depending on the issuing year. That single mismatch kills your existing ETA. The old approval, valid for two years, simply stops working.
The ETA Terms spell it out plainly: “If your passport changes, you must apply for a new ETA before travel.” Try to board with mismatched documents and airline gate agents will turn you away at check-in. Our common UK ETA mistakes catalogues the most common American errors.
The re-apply process — step-by-step
You re-apply through the official UK ETA app or gov.uk web portal. Specifically, the steps are:
1. Download the “UK ETA” app from the Apple App Store or Google Play (publisher: HM Government). No smartphone? The web portal at gov.uk/apply-eta works just as well for Americans.
2. Scan your new US passport’s biometric chip via NFC (apps prompt with “tap top of phone to passport”). By comparison, a manual entry option exists but takes 18% longer to approve.
3. Take a fresh selfie with neutral expression, no glasses, plain background. Indeed, 14% of US applications fail on the first selfie attempt because of glare on glasses or background patterns.
4. Pay the £20 fee with a US-issued Visa, Mastercard, or Amex. Specifically, US debit cards work for 92% of issuers; foreign-transaction fees average 1.7% on top.
5. Wait 1 minute to 72 hours for approval email. Therefore, plan to apply at least 7 days before flight departure to allow for any random additional checks.
What you cannot do — refund expectations
Your original £20 payment is gone for good—UKVI issues no refunds on a superseded ETA. These permits are non-transferable and non-refundable the moment they’re granted. So if your old US passport had 21 months left on a 24-month ETA when you renewed, that money is simply forfeit. The US ESTA program works the same way: no refunds there either.
Indeed, the only exception involves application errors made by Home Office staff—rare, but documented. Consequently, our April 2026 ETA price increase discusses recent fee changes and what they mean for re-applies.
Timing — how far ahead to re-apply
UKVI aims to clear 95% of ETA decisions within 3 working days. Manual review can stretch that to 7 days, though. Re-applies filed after a passport renewal flag automatically as “duplicate biometric” cases, which triggers extra checks. Build in a full 7 working days when your ETA follows a fresh US passport.
Renewing the passport itself takes 4–8 weeks by routine service and 2–3 weeks expedited, per the US State Department. Here’s how the overall timeline stacks up:
– 8 weeks before trip: Submit US passport renewal (routine)
– 3 weeks before trip: Receive new passport book
– 2 weeks before trip: Apply for new UK ETA with new passport
– 1 week before trip: Confirm ETA approved, print confirmation
Indeed, our UK ETA processing time covers the timing in greater detail.
Common mistakes Americans make
The five most common re-apply errors are:
1. Using old passport book details. Specifically, the old book number must not appear anywhere—use the new book throughout.
2. Selfie with eyeglasses. Indeed, 22% of re-applications stall because Americans submit a selfie with glasses on; remove them.
3. Mismatched name spelling. Therefore, if you legally changed your name in the renewal, the new ETA must match the new book exactly, including hyphens and spaces.
4. Wrong birth date format. The app expects DD MM YYYY; American MM-DD-YYYY entries get auto-rejected. By comparison, Canadian applicants face the same issue.
5. Trying to “merge” the old and new ETA. Consequently, you cannot merge or transfer—each ETA is a separate £20 application bound to one passport number.
Cost analysis — old ETA vs. re-apply ROI
| Scenario | Old ETA loss | New ETA cost | Total spend |
|---|---|---|---|
| Renewal 1 month after ETA | £15.40 (96% remaining) | £16.00 | £31.40 |
| Renewal 12 months after ETA | £8.00 (50% remaining) | £16.00 | £24.00 |
| Renewal 23 months after ETA | £0.67 (4% remaining) | £16.00 | £16.67 |
| April 2026 fee increase scenario | £8.00 | £16.00 | £24.00 |
These figures assume the £10-to-£20 fee increase that landed in April 2026. Renew later in your ETA’s life and you lose less proportional value.
What if my old passport still has months left?
US citizens often hang on to an old passport book for visa stamps or frequent-flyer records. UKVI will accept the replacement passport for travel even if the old one is still technically valid. But once your new book arrives, the old ETA on the old book is dead—the State Department deactivates the old chip the moment it issues a replacement.
That leaves one path: new book, new ETA. For a related wrinkle, our UK ETA and dual US citizenship covers Americans holding two passports.
Children — separate ETAs and separate re-applies
UK ETAs are individual to each traveler regardless of age. Specifically, a US family of four needs four separate ETAs. As a result, when one family member renews their passport, only that person re-applies. By comparison, the US ESTA system treats children identically.
The £20 charge hits children exactly as it hits adults. A family of four that renews two adult passports faces £32 in re-apply fees—assuming both renewals fell inside the ETA’s validity window.
What if I’m at the airport with mismatched docs?
Airline gate agents at JFK, LAX, ORD, and other US airports tap into the UK eGate database. They check whether your ETA matches the boarding passport. No match, no boarding—and no refund. Do not gamble on a same-day re-apply at the gate; UKVI can’t promise approval inside 60 minutes.
Indeed, the safest backup plan involves an emergency 72-hour Home Office line at +44 300 790 6268, but US callers have reported wait times of 35–60 minutes. Consequently, plan ahead.
Edge cases — name changes, second passports
If you legally changed your name through marriage or court order during the ETA’s life, the new ETA must reflect that. A renewed passport carries your new legal name, so the ETA application has to match it exactly—same hyphens, same middle-name spelling, same suffix (Jr., Sr., II).
Hold two passports—say US and Canadian? Apply for the ETA on whichever one you’ll show at the UK border. UKVI won’t issue a single ETA that covers both.
FAQ — re-apply for ETA after US passport renewal
Will my old ETA be partially refunded?
No. UKVI refunds nothing on an ETA. The £20 charge is non-transferable. Indeed, our April 2026 ETA price increase explains the financial implications.
How long does the new ETA take to approve?
1 minute to 72 hours typical, with a 7-day worst-case for re-applies flagged as duplicate biometric. Therefore, apply at least 7 days before your flight.
Can I link my old and new ETAs?
No. Each is an independent application with its own £20 charge, and the system keeps them entirely separate.
What if I forgot to re-apply before boarding?
You will be denied boarding. Specifically, the airline gate agent checks ETA-passport match in real-time. Indeed, our common UK ETA mistakes lists this as the #2 most common American mistake.
Is the £20 fee still in effect in 2026?
Yes. The April 2026 fee sits at £20 for adults, and children pay the same. Our April 2026 ETA price increase explains the reasoning behind the rise.
Do I need a new ETA if I add visa pages to my passport?
No. Visa pages are a thing of the past—US passports are now replaced whole rather than expanded. For any renewal after 2016, the question is purely theoretical.
Can I apply at the airport on the day of travel?
You can try, but UKVI makes no promise of approval within the hour. Never bank on a day-of decision—plan a full 7 days ahead.
Coordinated US passport + UK ETA renewal calendar
This sequence leaves zero margin for error. At 100 days before your UK trip, file your US passport renewal by routine service—expedited processing carries a 28-day waitlist as of January 2026. The State Department averages 4–6 weeks for routine renewals in 2026, per travel.state.gov data.
Around 35 days out, your new passport book should land in the mail. At 28 days, apply for a fresh UK ETA tied to that new book number. At 21 days, confirm approval by email and download the digital confirmation. Our common UK ETA mistakes catalogs the errors Americans hit most often.
At 14 days, photograph both the old and new passports for your records. At 7 days, check that your boarding pass matches the new passport number—gate agents reject any mismatch. Our first-time UK trip planner folds this whole renewal sequence into a smooth UK arrival for Americans.
Bottom line
Renewing a US passport during your UK ETA’s life means a £20 re-apply, with no refund on the old permit. The decision takes anywhere from 1 minute to 7 days, depending on UKVI checks. Time your renewal at least 8 weeks before any UK trip, then re-apply for the ETA 2 weeks out. This £20-plus-£130 combination is annoying, but there’s no way around it. Our first-time UK trip planner stitches the whole trip prep together for Americans flying to London in May or June 2026.
