UK ETA for Americans: Cost, Requirements & How to Apply (2026)

Last Updated: May 2026

As of February 25, 2026, every American traveling to the United Kingdom needs an approved Electronic Travel Authorisation (ETA) before boarding a flight, ferry, or Eurostar. The fee is £20 (~$25 USD), the authorization is valid for 2 years with unlimited trips, and most applications are approved within minutes. The previous visa-free entry without pre-authorization is no longer available — even for short tourist trips.

This guide focuses on US-specific UK ETA requirements. For the general overview that applies to all 85 visa-exempt nationalities, see our complete UK ETA guide.

Do Americans Need a UK ETA?

Yes. Since February 25, 2026, every US passport holder traveling to the United Kingdom as a visitor must have an approved Electronic Travel Authorisation (ETA) before boarding. This is confirmed in the official notice from the U.S. Embassy in the United Kingdom.

Before February 25, 2026, Americans could fly to the UK with just a valid passport. That changed. The UK ETA is now mandatory for all short visits — tourism, business, family visits, or transit through UK border control. There is no grace period and no exceptions for short stays.

The ETA is similar in concept to the US ESTA program that the United States requires from visa-exempt visitors. It’s a digital pre-screening that checks travelers against security databases before allowing boarding. It’s not a visa, but you can’t board a UK-bound flight without one.

How Much Does a UK ETA Cost in USD?

The UK ETA costs £20, which is approximately $25 USD depending on current exchange rates. This price has been in effect since April 8, 2026, when the fee increased from £16. The cost is the same whether you apply directly through the UK government or through a service like iVisa (which adds its own processing fee on top).

Payment is made online using a credit or debit card. To avoid foreign transaction fees from your US bank, use a credit card with no international transaction fees (most travel rewards cards qualify).

How Americans Apply for a UK ETA — Step by Step

The application takes most Americans under 10 minutes from start to finish. Here’s exactly what to do:

1. Choose your application method. Americans have three options:

• The official UK ETA app (Apple App Store, Google Play) — recommended by the UK government because it can scan your US passport chip directly, reducing data entry errors.
• The official UK government website at GOV.UK/eta.
• A guided service like iVisa — useful for dual citizens, families, or anyone who wants form review and customer support.

2. Have your US passport ready. You’ll need to enter your passport number, expiration date, and other details. The UK government recommends having at least 6 months of validity on your passport before travel.

3. Take a photo of yourself. The app guides you through a passport-style face photo. The web application accepts uploaded photos meeting UK requirements.

4. Answer security screening questions. These cover criminal history, previous immigration issues, and the purpose of your trip. Answer truthfully — false answers cause refusals.

5. Pay £20 by card. You’ll receive an email confirmation with your 16-digit ETA reference number.

6. Wait for the decision. Most Americans are approved within minutes. Some applications are flagged for manual review (up to 3 working days). The UK government recommends applying at least 3 working days before your flight.

UK ETA vs. US ESTA: The Comparison Every American Wants

If you’ve ever applied for a US ESTA on behalf of a foreign visitor — or even just heard of it — you already understand the UK ETA. The two systems are nearly identical in concept, though there are key differences:

	UK ETA	US ESTA
Who needs it	Visa-exempt visitors to UK	Visa-exempt visitors to US
Cost	£20 (~$25)	$40.27
Validity	2 years	2 years
Max stay per trip	6 months	90 days
Processing	Minutes — 3 working days	Minutes — 72 hours
Travel purposes	Tourism, business, transit	Tourism, business, transit

The biggest practical difference: the UK gives Americans up to 6 months per visit, compared to 90 days for foreigners visiting the US. The UK ETA also lasts 2 years like ESTA. The application process feels nearly identical from the user side.

The Heathrow Transit Question Most Americans Get Wrong

This is one of the most-asked questions from US travelers connecting through London on their way elsewhere in Europe — and the answer depends on what type of transit you’re doing:

When in doubt, contact your airline before departure. The safest move for Americans transiting through Heathrow with anything other than a single same-airline itinerary is to apply for the ETA anyway. It’s £20 and lasts 2 years.

Driving from Ireland to Northern Ireland: Yes, You Still Need an ETA

Many Americans planning to fly into Dublin and then drive across the border to visit Belfast or the Giant’s Causeway assume they don’t need a UK ETA because the Irish border has no checkpoints. This is wrong.

Northern Ireland is part of the United Kingdom. Even though the land border between the Republic of Ireland and Northern Ireland has no immigration controls in practice, US citizens are legally required to hold a valid UK ETA when entering Northern Ireland by any means — including driving from the Republic.

If you’re combining Ireland with Northern Ireland on the same trip, apply for the UK ETA before you fly to Dublin.

What’s Covered by One ETA: All Four UK Nations

A single UK ETA covers all four nations of the United Kingdom: England, Scotland, Wales, and Northern Ireland. You don’t need separate authorizations for trips to Edinburgh, Cardiff, or Belfast. The ETA applies to the entire UK as one country for immigration purposes.

It does NOT cover the Republic of Ireland (a separate country with its own immigration system), the Channel Islands (Jersey, Guernsey), or the Isle of Man (technically separate jurisdictions, though most US citizens are still allowed visa-free entry there for short visits).

Common Mistakes Americans Make

Applying through unofficial third-party sites with inflated fees. Some sites charge $80 or more for what is essentially the £20 UK government application plus their markup. The official UK app and website charge only the £20 government fee. Trusted services like iVisa are transparent about their fee structure — many shady sites are not.

Confusing the ETA with a visa. The ETA is for short visits only. It does not allow you to work, study long-term, or live in the UK. Trying to use an ETA for work-related travel can result in being refused at the border and a 1-5 year entry ban.

Planning to “switch to a visa” after arriving. The UK expects you to obtain the correct visa before entering. Don’t enter on an ETA with plans to apply for a work or student visa from inside the UK.

Forgetting that every traveler needs their own ETA. There are no family applications. A family of four needs four separate ETAs, including babies in arms. You can apply on behalf of each family member.

Renewing your passport and forgetting the ETA is tied to it. The ETA is linked to your specific passport number. If you renew your passport, you need a new ETA — even if the old one hasn’t expired.

Travel Insurance for Americans Visiting the UK

The UK doesn’t require Americans to have travel insurance for visa-exempt entry, but you’d be foolish to travel without it. The NHS (UK National Health Service) does not provide free care to American tourists. A non-trivial illness or injury in London can result in bills running into thousands of dollars, and your US health insurance almost certainly doesn’t cover you abroad.

Combining a UK Trip with European Travel

Many Americans visit the UK as part of a broader European trip. Important rules to understand:

The UK is not part of the Schengen Area. Time spent in the UK does not count toward your 90-day Schengen limit. This makes the UK an excellent “reset” destination for Americans wanting to extend their European travel beyond 90 days.

Starting in Q4 2026, Americans will also need an ETIAS authorization for the Schengen Area — a separate system from the UK ETA. If you’re planning a trip that includes both the UK and countries like France, Spain, or Italy, you’ll need both authorizations.

Frequently Asked Questions

Do American children need a UK ETA?
Yes. Every US passport holder needs an ETA, including babies and children. There are no family applications — each person needs their own ETA. You can apply on behalf of your children from the same device.

How long is the UK ETA valid for Americans?
The UK ETA is valid for 2 years from the date of approval, or until your US passport expires (whichever comes first). During that 2-year period, you can take unlimited trips to the UK, with each stay lasting up to 6 months.

What happens if my UK ETA application is denied?
There is no appeal process for ETA refusals. Your alternative is to apply for a Standard Visitor Visa, which involves a more detailed application reviewed by a UK Visas and Immigration caseworker. This is a longer and more expensive process. If you believe the denial was based on incorrect information, you can submit a new ETA application.

Can I work in the UK on an ETA?
No. The ETA only authorizes short visits for tourism, business meetings (not paid work), family visits, and short courses. To work in the UK, you need a specific work visa. Working on an ETA is illegal and can result in deportation and future entry bans.

Do I need a UK ETA for a connecting flight through London?
Only if you pass through UK border control. Airside transit (staying in the international transit area without going through immigration) doesn’t require an ETA. Landside transit (collecting bags, changing terminals via landside, or leaving the airport) requires an ETA. If you booked your tickets separately and need to recheck bags in London, you almost certainly need an ETA.

Does my UK ETA cover Scotland, Wales, and Northern Ireland?
Yes. A single UK ETA covers all four nations of the United Kingdom: England, Scotland, Wales, and Northern Ireland. You don’t need additional authorizations to visit Edinburgh, Cardiff, or Belfast.

Can I apply for a UK ETA at Heathrow when I arrive?
Technically possible (it’s a digital application), but very risky. Most ETAs are approved in minutes, but some applications are flagged for manual review which can take up to 3 working days. Airlines are required to check ETA status before boarding — if you don’t have an approved ETA when you check in for your flight to the UK, you won’t be allowed to board. Apply at least 3 working days before travel.

I have dual US/UK citizenship — do I need a UK ETA?
No. UK citizens (including dual nationals) cannot get a UK ETA. You must travel to the UK on your British passport or with a Certificate of Entitlement. If you only have a US passport but are entitled to British citizenship through descent, contact the British Embassy about your options.

I have dual US/Irish citizenship — do I need a UK ETA?
No. Irish citizens are exempt from the UK ETA under the Common Travel Area agreement. If you hold both US and Irish passports, travel to the UK on your Irish passport.

Will the UK ETA expire when my passport does?
Yes. The ETA is linked to your specific US passport. If your passport expires before the 2-year ETA validity period ends, the ETA expires with it. If you renew your passport, you need to apply for a new ETA — even if the original one hasn’t expired.

Does the UK ETA replace travel insurance?
No. The ETA is just travel authorization. The UK does not require visitors to have travel insurance, but US health insurance generally doesn’t cover medical care abroad. For peace of mind and protection against unexpected medical costs, get a separate travel insurance policy.
