Apply for a new UK ETA after passport renewal

This is not a bureaucratic technicality. Arriving at the UK border with an old ETA linked to an expired or cancelled passport means arriving with no authorisation at all. Airlines will flag you. Border Force will turn you back. The £10 you saved by not reapplying will cost you a missed flight, a missed meeting, or a missed connection worth significantly more.

Here is the exact sequence you need to follow.

The Digital Link: Why Your Old ETA Is Dead on Arrival

The UK Electronic Travel Authorisation is not a paper document you carry in your wallet. It is a digital permission stored in Home Office systems, keyed to the passport number you provided during your application.

When a border officer scans your passport at a UK port of entry, the system cross-references that passport number against the ETA database. Match found — you proceed. No match — you are an unauthorised traveller, regardless of what your old ETA approval email says.

Your ETA does not travel with you as a document. It travels with your passport number. Change the number, lose the authorisation.

This is a hard eligibility threshold, not a soft guideline. The system was designed this way deliberately. Passport numbers serve as the primary identity anchor in the digital border scheme, and every piece of authorisation data — validity window, approval status, biometric match — chains back to that single identifier.

Renewing your passport generates a new number. The moment your old passport is cancelled in the issuing country's system, the link between that number and your ETA becomes meaningless. You cannot call the Home Office to "reactivate" it. You cannot submit a correction form. You must start over.

Why Transfer Is Not an Option — And Never Will Be

The question comes up constantly: can I update my existing ETA with my new passport number? The answer is no. The system does not support amendments, edits, or transfers.

This is not an oversight or a missing feature. It is a deliberate design choice embedded in the architecture of the UK's digital border scheme. Each ETA is a discrete record tied to a specific document. Allowing transfers would introduce identity verification gaps — exactly the kind of vulnerability the scheme was built to eliminate.

The operative word in every row where action is required: full. Not partial. Not an update. A complete, standalone application with its own fee, its own processing window, and its own approval decision.

The £10 Reapplication: Exact Steps, No Guesswork

The cost of a new UK ETA application is £10 per applicant. Children and infants require their own separate applications at the same fee. There is no family discount, no group rate, no expedited premium tier at the time of writing.

Here is the sequential process:

1. Secure your new passport physically. You need the passport in hand — not a digital scan from your government's portal, not a confirmation email that the document is "on its way." The application requires the passport number, expiry date, and issuing country exactly as printed.

2. Access the official application channel. Use either the UK government's GOV.UK portal or the UK ETA mobile application. Do not use third-party intermediaries. Unauthorised sites charge inflated fees and introduce data security risks into your application.

3. Complete the biographical data fields. Name, date of birth, nationality — all must match your new passport exactly. A single mismatched character between your ETA application and your passport data triggers manual review and delays.

4. Submit passport details from the NEW document. This is the critical failure point. Applicants who recently renewed frequently enter their old passport number by muscle memory or by copying from a saved document. Double-check every digit.

5. Answer eligibility and background questions. Criminal history, immigration violations, prior UK entry refusals — answer honestly. The Home Office cross-references your responses against international databases. Discrepancies here do not just delay your application; they can result in outright refusal.

6. Pay the £10 fee and submit. Payment processes through a standard card transaction. You receive a confirmation reference immediately.

The application takes roughly fifteen minutes. The processing takes up to three working days. The cost of getting it wrong at the border is immeasurably higher than both.

Timing: When to File Relative to Your Travel Date

Standard processing for a UK ETA application is three working days. The Home Office frames this as "typically within 3 working days," which means some decisions arrive faster — sometimes within hours — but you should plan around the upper bound, not the best case.

The strategic move: submit your new ETA application the same week you receive your renewed passport. Do not wait until you have a flight booked. Do not wait until you are packing. The two-year validity window means you lose nothing by applying early, and you gain a critical buffer against processing delays.

What causes delays beyond the standard three-day window:

• Name discrepancies between the application and passport (transliteration issues are common for non-Latin script names)

• Prior immigration history flags that trigger manual review

• High-volume periods following public holidays or scheme roll-out milestones to new nationalities

If your travel date is within 72 hours and you have not yet applied, you are accepting risk. There is no guaranteed same-day or next-day processing pathway publicly available. Plan accordingly.

Verifying Your New Authorisation Status Before Departure

You will receive a confirmation email when your new ETA is approved. But email confirmations are not what border officers check. The verification lives in the system.

Before you fly, confirm your ETA status through one of these methods:

• Check your application status via the GOV.UK portal using your application reference number

• Open the UK ETA app and verify the authorisation appears linked to your new passport number

• Contact UK Visas and Immigration if more than five working days have passed with no decision

Do not assume approval. Do not assume your new ETA "probably went through." Verify it as you would verify any critical document before a high-stakes trip.

For travelers managing complex itineraries or connecting through multiple countries, staying informed about broader entry policy changes matters as much as securing your own documents. Resources covering practical travel updates and guidance can help you stay current on shifts that affect your route.

The Refusal Risk Nobody Talks About

Here is the scenario that catches people off guard: your new ETA application gets refused.

It happens. Not frequently, but enough that you need a contingency plan. Common grounds for refusal include:

• Undisclosed immigration violations in the UK or other countries

• Criminal convictions that were not disclosed (or were disclosed incorrectly)

• Data mismatches between your application and Home Office records from previous interactions

• Fraudulent or altered document detection during automated checks

A refusal does not just mean you cannot fly tomorrow. It creates a record. That record surfaces on every future UK immigration application — visas, sponsorships, entry clearances. The cascading cost of a refused ETA dwarfs the inconvenience of applying correctly the first time.

Mitigate the risk before you submit. Review your travel history. Confirm your criminal record status if you have any doubt. Ensure your passport data is entered flawlessly. If you have prior UK immigration complications — overstays, refused applications, removals — consult an immigration adviser before filing.

The £10 application is simple. The consequences of getting it wrong are not.

---

Bottom line: Passport renewal kills your UK ETA instantly. There is no workaround, no amendment process, no customer service line that can fix it retroactively. Apply for a new ETA immediately upon receiving your new passport, verify approval before you book travel, and treat the three-day processing window as a minimum — not a promise. The digital border does not negotiate.
