Introduction: Comparing Two Electronic Travel Systems<\/h2>\n

The United Kingdom and the United States both operate electronic travel authorisation systems designed to screen visitors before they arrive. The UK’s Electronic Travel Authorisation (ETA) and America’s Electronic System for Travel Authorization (ESTA) share many similarities but also have important differences that travellers should understand.<\/p>\n

If you are planning a trip that includes both the United Kingdom and the United States, or if you are simply curious about how these two systems compare, this guide breaks down every key detail. From costs and validity periods to application processes and refusal procedures, we cover everything you need to know.<\/p>\n

What Is the UK ETA?<\/h2>\n

The UK ETA is a mandatory digital travel authorisation for visitors from visa-exempt countries who wish to enter the United Kingdom. Introduced in 2025, it applies to short stays of up to six months and covers tourism, business visits, transit, and other permitted activities. The ETA is not a visa but rather a pre-screening tool that allows UK border authorities to assess travellers before departure.<\/p>\n

All visa-exempt nationals, including American citizens, must obtain a UK ETA before travelling. Applications are submitted through the official UK ETA app or the GOV.UK website. For full details, see our complete UK ETA guide<\/a>.<\/p>\n

What Is the US ESTA?<\/h2>\n

The US ESTA (Electronic System for Travel Authorization) is part of the Visa Waiver Program (VWP), which allows citizens of 41 participating countries to visit the United States for tourism or business without obtaining a visa. ESTA has been operational since 2009 and is one of the longest-running electronic travel authorisation systems in the world.<\/p>\n

ESTA applies to travellers visiting the US for up to 90 days. It is mandatory for all VWP country nationals arriving by air or sea. Unlike the UK ETA, ESTA is not required for land border crossings from Canada or Mexico, though other documentation may be needed.<\/p>\n

Cost Comparison<\/h2>\n

The UK ETA costs \u00a320, which is approximately $20 USD at current exchange rates. The US ESTA costs $21 USD. In practical terms, both authorisations cost a similar amount, making them among the most affordable travel requirements in the world.<\/p>\n

The UK government has announced plans to increase the ETA fee to \u00a320 at some point during 2026, though no specific date has been confirmed. If this increase goes ahead, the UK ETA would become slightly more expensive than the US ESTA in dollar terms.<\/p>\n

Both fees are non-refundable, regardless of whether your application is approved or denied. There is no premium or expedited processing option for either system.<\/p>\n

Validity and Length of Stay<\/h2>\n

Both the UK ETA and US ESTA share the same two-year validity period (or until your passport expires, if sooner). During this time, you can make unlimited entries to the respective country. This means that frequent travellers to either destination only need to apply once every two years.<\/p>\n

The major difference lies in the maximum length of each visit. The UK ETA permits stays of up to six months per entry, which is remarkably generous. The US ESTA, by contrast, limits each visit to 90 days. This difference can be significant for business travellers, those visiting family, or anyone planning an extended stay.<\/p>\n

It is worth noting that while the UK technically allows six-month stays, immigration officers may question travellers who repeatedly stay for extended periods. Similarly, US border officials can deny entry to ESTA holders who appear to be using short visits to effectively live in the country.<\/p>\n\n

Application Process Compared<\/h2>\n

Applying for the UK ETA<\/h3>\n

The UK ETA application is completed through the dedicated UK ETA app (available on iOS and Android) or via the GOV.UK website. The process involves several steps: entering your personal details, providing passport information, answering eligibility and security questions, uploading a facial photograph taken through the app, and paying the \u00a320 fee by debit or credit card.<\/p>\n

Most UK ETA applications are processed within three working days, with many receiving same-day approval. The ETA is digitally linked to your passport number, so no physical document is issued. For a detailed walkthrough, visit our UK ETA application guide<\/a>.<\/p>\n

Applying for the US ESTA<\/h3>\n

The US ESTA application is completed entirely online through the official US Customs and Border Protection website. You must provide personal details, passport information, employment details, and answer a series of eligibility questions covering criminal history, health conditions, and previous travel. No photograph upload is required during the application.<\/p>\n

ESTA applications are usually processed within 72 hours, though many are approved almost instantly. Like the UK ETA, the ESTA is electronically linked to your passport. Travellers should be cautious of third-party websites that charge inflated fees for ESTA applications. The only official site is the CBP website.<\/p>\n

Who Needs Each Authorisation?<\/h2>\n

UK ETA requirements<\/h3>\n

The UK ETA is required for all visa-exempt nationals visiting the United Kingdom. This includes citizens of the United States, European Union member states, Canada, Australia, Japan, and many other countries. American citizens have needed a UK ETA since 2 April 2025. For specific guidance for US travellers, see our UK ETA for Americans guide<\/a>.<\/p>\n

British and Irish citizens do not need an ETA, nor do holders of valid UK visas or those with settled or pre-settled status.<\/p>\n

US ESTA requirements<\/h3>\n

The US ESTA is required for citizens of 41 countries that participate in the Visa Waiver Program. This includes the United Kingdom, most EU member states, Australia, New Zealand, Japan, South Korea, and others. Citizens of countries not in the VWP must apply for a US visa instead.<\/p>\n

Notably, the VWP is more restrictive than the UK’s visa-exempt list. Some countries whose citizens can visit the UK without a visa do not qualify for the US VWP and must therefore obtain a US visa.<\/p>\n

Travelling to Both the UK and the US on the Same Trip<\/h2>\n

It is increasingly common for travellers, particularly those from Europe, Australia, or Asia, to visit both the United Kingdom and the United States during a single trip. If you plan to do so, you will need both a valid UK ETA and a valid US ESTA, as the two systems are completely independent.<\/p>\n\n

\"UK<\/figure>\n\n\n

Example itinerary: London to New York<\/h3>\n

Consider a Japanese traveller flying from Tokyo to London for three days, then continuing to New York for a week. This person would need a UK ETA (\u00a320) for the London stopover and a US ESTA ($21) for the New York visit. Both should be applied for well in advance of travel.<\/p>\n

Transatlantic transit<\/h3>\n

If you are transiting through the UK on your way to the United States, you will need a UK ETA even if you do not plan to leave the airport. The UK requires ETAs for airside transit, unlike many other countries. Similarly, if your return journey routes through a US airport, you would need an ESTA or appropriate visa.<\/p>\n

What Happens If Your Application Is Refused?<\/h2>\n

UK ETA refusal<\/h3>\n

If your UK ETA is refused, you can request a free administrative review. A different caseworker will reassess your application. Common reasons for refusal include criminal history, previous immigration violations, or errors in the application. If the review is unsuccessful, you may apply for a Standard Visitor Visa as an alternative. For more information, read our UK ETA refusal help guide<\/a>.<\/p>\n

US ESTA refusal<\/h3>\n

The US ESTA does not offer a formal appeal process. If your application is denied, you cannot request a review of that specific decision. Instead, you would need to apply for a B-1\/B-2 visitor visa through a US embassy or consulate. ESTA denials may occur if you have previously overstayed in the US, have certain criminal convictions, or have travelled to specific countries.<\/p>\n

This is a notable difference: the UK system offers a more transparent review process, while the US system essentially requires you to start a full visa application if ESTA is denied.<\/p>\n

Security and Data Requirements<\/h2>\n

Both systems collect personal and travel-related data to screen applicants against security databases. However, the UK ETA requires a biometric facial photograph as part of the application, while the US ESTA does not collect biometric data during the online application phase. US biometric data (fingerprints and photograph) is instead collected upon arrival at the US border.<\/p>\n

Both the UK and US authorities share data with each other and with other international partners as part of broader security cooperation agreements. Information provided in your applications may be cross-referenced with criminal databases, immigration records, and intelligence systems.<\/p>\n

Important Differences for Business Travellers<\/h2>\n

Both the UK ETA and US ESTA allow business-related visits, but the permitted activities differ. Under the UK ETA, you can attend meetings, conferences, and negotiations; conduct site visits; and engage in certain professional activities for up to six months. However, you cannot work for a UK employer or provide services to UK clients for payment.<\/p>\n\n

\"UK<\/figure>\n\n\n

Under the US ESTA, business activities are limited to attending meetings and conferences, negotiating contracts, and consulting with business associates. The 90-day limit is significantly shorter than the UK’s six months, which can be restrictive for complex business projects. For work-related activities in either country, a work visa is required.<\/p>\n

Comparison of Eligible Nationalities<\/h2>\n

The UK’s visa-exempt list is broader than the US Visa Waiver Program. Several countries whose citizens can visit the UK with just an ETA would need a full visa to visit the United States. Conversely, all 41 VWP countries are also eligible for the UK ETA.<\/p>\n

This means that if you hold a passport from a VWP country, you can use electronic authorisations for both destinations. But if your country is ETA-eligible for the UK but not part of the US VWP, you would need an ETA for the UK and a visa for the US.<\/p>\n
