UK ETA Documents Needed in 2026: Full Application Checklist

Getting your paperwork ready before you start is the secret to a fast, first-time approval. The good news is that the list of UK ETA documents is short — you won’t gather a single bank statement, hotel booking or invitation letter. This guide sets out exactly what you need to prepare so your application clears in minutes rather than days.

TL;DR: The core UK ETA documents are a valid biometric passport, a clear digital photo, a payment card for the £20 fee and an email address for the decision. You do not need to upload travel bookings or financial evidence. Each traveller, including children, needs their own set.

What UK ETA documents do you actually need?

What you actually need is a current biometric passport, a face photo, a debit or credit card and a working email address — nothing more. The application is deliberately light, and the official UK ETA guidance confirms you don’t have to submit accommodation bookings, return tickets, bank statements or sponsor letters (UK Home Office, checked 23 June 2026). This makes the ETA far simpler than a full visa application.

That simplicity is by design. The ETA is a pre-travel screening permission, so it collects only what is needed to confirm your identity and run suitability checks. If your nationality is not yet sure to require an ETA, confirm it first with our UK ETA eligible countries guide before gathering anything.

Your passport: the most important UK ETA document

Your passport is the single most important UK ETA document, and it must be a biometric passport with a working chip — the one you’ll actually travel on. The official app reads the electronic chip inside the passport to confirm your identity, so an older non-biometric document cannot be used. The ETA is then linked digitally to that exact passport number, which is why a new passport always means a new application.

Two passport points catch travellers out. First, the ETA is tied to one passport, so you must apply with the document you will actually present at the border. Second, if you renew your passport after applying, the old ETA is voided and you must reapply and pay the £20 charge again (the official ETA guidance, as of 23 June 2026). Always check your passport’s validity covers your trip before you start.

Important: You do not upload a scanned copy of your passport like a visa application. Instead, the official app scans the passport chip directly. Make sure your passport is the biometric type with the chip symbol on the cover before you begin.

The digital photo requirement

Every applicant needs one sharp digital photo as part of their paperwork, and the app can capture it live during the application. The photo must show your full face, be well lit and free of glare or obstructions. Unlike a passport photo, you usually take it within the app, which checks the quality before you submit. A poor photo is one of the most common reasons an application is delayed for manual review.

Children and babies need their own photo too, which can be the trickiest part for families. Our dedicated UK ETA photo requirements guide explains how to get an acceptable image first time, including tips for photographing infants. Getting the photo right is the easiest way to keep your application in the fast, automated lane (reviewed 23 June 2026).

Payment and email: the documents people forget

Beyond your passport and photo, the two items people forget are a valid payment card and a reachable email address for the decision. The fee is £20 per person, paid during the application; it rose from £10 to £16 in April 2025 and again to £20 on 8 April 2026 — increases that apply to every applicant (gov.uk ETA guidance, current as of 23 June 2026). No family bundle exists, so a family of four pays four separate fees.

The email address matters more than people expect, because your approval is sent there and nowhere else. A typo in your email can make an approved ETA look missing, since nothing is printed — the authorisation lives digitally against your passport. Use an address you can access while travelling, and double-check it before you submit, as advised by UK Visas and Immigration (verified 23 June 2026).

What UK ETA documents do you NOT need?

You do not need travel bookings, financial evidence, accommodation details or invitation letters as UK ETA documents. Many travellers expect a visa-style evidence bundle and are relieved to find none is required. You will not upload flight tickets, hotel reservations, bank statements, employment letters or proof of funds at any stage of the standard application.

This is a key difference between an ETA and a visa. If your trip genuinely needs that kind of evidence — for example a long stay, work, or study beyond the visitor rules — then an ETA is not the right route and you should use the UK ETA or visa decision guide. For ordinary short visits, your passport, photo, card and email are the complete set.

UK ETA documents checklist before you apply

Run through this short UK ETA documents checklist before you start, and your application should take under fifteen minutes per person. Having everything ready in advance is the difference between an instant approval and a frustrating delay. Most decisions arrive within minutes, though you should allow up to three working days before travel just in case.

1. Valid biometric passport for each traveller, with enough validity for the trip.
2. A device that can scan the passport chip, usually a smartphone with the official app.
3. A digital face photo for every applicant, including children.
4. A debit or credit card to cover the £20 fee per person.
5. A reliable email address you can check while away.

With these ready, apply only through the official gov.uk service and never a third-party reseller. Confirm your need first with the check if you need a UK visa tool if you are unsure (UK Home Office, retrieved 23 June 2026).

How long do your UK ETA documents stay valid?

Once issued, your UK ETA stays valid for two years or until your passport expires, whichever comes first. That means the document you applied with effectively sets the lifespan of your authorisation. If your passport has only a year left, your ETA will expire after a year too, even though the standard validity is two years. Checking your passport’s expiry date before you apply can save you from a surprise reapplication.

Within that validity window, you can visit the UK as many times as you like, with each stay capped at six months. No cap applies to the number of trips, and there’s no need to reapply between them, as long as your passport and ETA both remain valid. This unlimited-entry feature is what makes the £20 cost such good value for frequent visitors over the two-year period (the Home Office ETA guidance, viewed 23 June 2026).

Keep your approval email for your own records, although you never present it at the border. Because the authorisation is linked electronically to your passport, airlines and border systems verify it automatically. The email simply helps you track when your two-year window started and when you will next need to prepare your documents again.

Frequently asked questions about UK ETA documents

What UK ETA documents do I need to apply?
A biometric passport, a clear face photo, a payment card for the £20 charge and an inbox you can reach for your decision. Nothing else is required.

Do I need to upload hotel bookings or bank statements?
No. The ETA does not require travel bookings, accommodation details or financial evidence at any point.

Can I apply with a non-biometric passport?
No. The application reads the passport chip, so a chipped biometric document is required to apply and to travel.

Do children need their own documents?
Yes. Every traveller, including babies, needs their own passport, photo and £20 application.

What if I get a new passport after applying?
A new passport voids your existing ETA. You must reapply, because the authorisation is linked to one specific passport.

In short, the uk eta documents you need amount to a biometric passport, a face photo and a payment card, plus an email address — no visa-style paperwork at all. Gather those four things, apply only through the official gov.uk service, and your authorisation should be approved within minutes, leaving you ready and fully prepared for a smooth, stress-free arrival in the UK.
