The UK ETA (eTA United Kingdom) costs £20, is valid for 2 years or until your passport expires, and allows multiple visits of up to 6 months each. Most applications made in the official UK ETA app are decided within minutes, but the Home Office asks travellers to allow up to 3 working days.
The UK Electronic Travel Authorisation (ETA) is a digital permission required for visitors who do not need a visa to enter the United Kingdom for short stays. Since its full rollout in 2025, the ETA has become a mandatory pre-travel clearance for citizens of over 85 countries, including the United States, Canada, Australia, Japan, and all EU member states.
This comprehensive guide covers everything you need to know about the eTA for the United Kingdom — from eligibility and cost to the application process and validity period.
What Is the UK Electronic Travel Authorisation?
The UK ETA is a digital travel permit introduced by the Home Office as part of the United Kingdom’s move toward a fully digital border system. It is similar in concept to the United States ESTA or the upcoming European ETIAS. The ETA is not a visa — it is a pre-travel authorisation that allows eligible travellers to board their transport to the UK.

Who Needs a UK ETA?
Most visitors to the UK who do not require a visa for short stays must obtain an ETA before travelling. This includes nationals from:
- All European Union countries (except Ireland)
- United States
- Canada
- Australia
- New Zealand
- Japan
- South Korea
- Singapore
- And many other visa-exempt nations
You do not need an ETA if you:
- Hold a British or Irish passport
- Already have a UK visa
- Have permission to live, work, or study in the UK
- Are a dual British or Irish citizen travelling on that passport
Every traveller needs their own ETA, including babies and children. You can apply on behalf of others.
The full UK ETA countries list, with the nationalities that still need a visa and the special rules for dual citizens and residents of Ireland, is on our UK ETA countries page.
How Much Does a UK ETA Cost?
The UK ETA costs £20 per person. This fee is non-refundable, even if your application is refused. You can pay by credit card, debit card, Apple Pay, or Google Pay.
Be cautious of third-party websites that charge higher fees. The official application is available through the UK ETA app or the GOV.UK website. Other websites may charge significantly more for the same service.
How to Apply for a UK ETA
There are two ways to apply for a UK ETA:
Apply via the UK ETA App
The easiest method is through the official UK ETA app, available on Google Play and the Apple App Store. The app guides you through:
- Taking a photo of your passport
- Scanning the chip in your passport
- Scanning your face
- Taking a photo of yourself
- Answering suitability and criminality questions
- Paying the £20 fee
Apply Online
If you cannot use the app, you can apply online through GOV.UK. You will need:
- A photo of your passport
- A photo of your face
- An email address
- A payment method
You can also apply for someone else online if they are not with you.
UK ETA App or GOV.UK Website: Which Should You Use?
The UK ETA app is usually the quicker route, because it reads the passport chip and checks your face during the application, so many decisions are automated. The GOV.UK online form suits travellers without a compatible phone or anyone applying for a person who is not with them; the photo is reviewed separately, so a decision can take from minutes to hours. The fee is £20 in both cases. Step-by-step instructions for each method are in our UK ETA application guide.
UK ETA Processing Time
Most applicants receive a decision within minutes when applying through the UK ETA app. However, the official guidance advises allowing up to 3 working days (Monday to Friday) for a decision.
Some applications may require additional review, which can take longer. It is recommended to apply at least three working days before your planned travel date.
You will receive your decision by email from UK Visas and Immigration (UKVI). The email contains your 16-digit ETA reference number.
Is the UK ETA Instant?
Not always. Many travellers applying through the app are approved within minutes, but there is no guaranteed instant approval and no paid express option: every application goes through the same queue. Applications flagged for a manual check, a mismatch between the passport and the photo or a typo in the email address can stretch the wait towards 3 working days. Applying several weeks before departure removes the risk, because the ETA stays valid for 2 years. Typical waiting times and what to do about delays are explained on the UK ETA processing time page.
UK ETA Validity Period
A UK ETA is valid for 2 years from the date of approval, or until your passport expires — whichever comes first. During this period, you can make multiple trips to the UK, with each stay lasting up to 6 months.
If your passport expires or is replaced, you must apply for a new ETA. Your ETA is electronically linked to the passport you used during the application.
How to Check If Your UK ETA Is Still Valid
The expiry date is shown in the GOV.UK “check an ETA” service. You need:
- the passport you used to apply,
- your 16-digit ETA reference number from the approval email.
The service shows whether the ETA is currently valid and the exact expiry date. If you have renewed your passport since applying, the old ETA no longer works and a new £20 application is needed. There is no way to extend or transfer an ETA; read more on the UK ETA validity and expiry page.
What You Can and Cannot Do with a UK ETA
With a UK ETA, you can:
- Visit the UK as a tourist
- Visit family and friends
- Attend business meetings and conferences
- Study for up to 6 months
- Transit through the UK (if passing through border control)
- Receive private medical treatment
You cannot:
- Work in the UK
- Claim public funds
- Live in the UK through frequent visits
- Get married or register a civil partnership (you need a marriage visitor visa)
UK ETA vs UK Visa
The ETA and a UK visa serve different purposes:
| Feature | UK ETA | UK Visa |
|---|---|---|
| Cost | £20 | £100–£1,000+ |
| Processing | Minutes to 3 days | Weeks to months |
| Validity | 2 years | Varies by visa type |
| Max stay | 6 months per visit | Depends on visa |
| Work allowed | No | Some visas allow work |
| Application | Online/app only | Online + embassy visit |
If you are from a country that does not qualify for the ETA, or if you need to work, study long-term, or settle in the UK, you will need to apply for the appropriate visa.
UK ETA for Families and Groups
Every person travelling to the UK needs their own ETA, regardless of age. This includes infants and children. You can apply for multiple family members through a single session on the UK ETA app or online.
If you are applying for someone else who is not physically with you, you must use the online application rather than the app.
UK ETA for Transit Passengers
If you are transiting through a UK airport and need to pass through border control (known as landside transit), you need an ETA. If you are transiting airside — meaning you stay in the international transit area and do not pass through passport control — you may not need an ETA.
Check with your airline if you are unsure whether you need to pass through UK border control during your transit.
Common UK ETA Mistakes to Avoid
- Applying through unofficial websites that charge inflated fees
- Not applying far enough in advance of travel
- Using a different passport for the application than the one you will travel with
- Forgetting to apply for children and infants
- Not checking if your nationality requires an ETA or a visa
