British passport holders travelling to the United States for tourism, business meetings, or transit under 90 days enter under the US Visa Waiver Program using an Electronic System for Travel Authorization (ESTA). The official total cost is $21 USD: a $4 processing fee and a $17 authorisation fee. The application is made directly at esta.cbp.dhs.gov, the official US Customs and Border Protection portal. Validity is two years multiple entry, with each visit limited to 90 days. This guide explains the application process, how long an ESTA lasts, common refusal reasons, and why third-party "ESTA processing" services are pure markup for a system designed to be applied for directly. It does not provide regulated immigration advice.
TL;DR - The 60-Second Answer
- The US ESTA is the standard authorisation for UK travellers under the Visa Waiver Program.- Official cost: $21 USD total ($4 processing + $17 authorisation) on esta.cbp.dhs.gov.

What the US ESTA does and who needs it
The Electronic System for Travel Authorization is the pre-arrival screening mechanism for travellers entering the United States under the Visa Waiver Program. The UK is one of 41 countries in the programme. Every UK passport holder, including infants and children, who travels to the US for tourism, business meetings, conferences, transit, or short medical visits under 90 days, requires an approved ESTA before boarding the flight to the US. Travellers entering for any longer period or for purposes outside the Visa Waiver Program scope require a US visa from the relevant consulate.
The ESTA is not a visa. It is an authorisation to travel to a US port of entry and request admission under the Visa Waiver Program. Final admission is at the discretion of US Customs and Border Protection officers at the airport or land border. The ESTA permits arrival; it does not guarantee entry. Most UK travellers experience a routine admission, but the distinction matters because an ESTA approval is not equivalent to a US visa.
What the ESTA does not cover
The ESTA cannot be used for paid employment in the US, for formal study leading to an academic credential, for journalism with US-based employment, or for any visit exceeding 90 days. UK travellers entering for any of these purposes need the appropriate US visa class: H-1B or L-1 for work, F-1 for academic study, J-1 for exchange programmes, and I for journalism. Using the ESTA as a workaround for work or extended residence is a recurring source of US entry bans and is monitored by CBP at the border.
How to apply for the ESTA at the official site
The official US government ESTA portal is esta.cbp.dhs.gov, operated by US Customs and Border Protection within the Department of Homeland Security. The application takes around 20 minutes for a first-time user. The form is more detailed than many other electronic authorisations and includes questions on personal history, prior visa refusals, employment, family ties in the US, social media identifiers, and a battery of eligibility questions covering past criminal convictions, communicable diseases, and certain country visits since 2011.
Required materials are the passport biographical page details, address details in the US for the first night (a hotel is fine), an email address, and a credit or debit card for the $21 payment. The application can be lodged from any device with internet access. Approvals typically arrive within minutes of submission; in a minority of cases the application enters a "Pending" status that resolves within 72 hours.
Honesty on the eligibility questions matters
The eligibility questions cover prior US visa refusals or revocations, prior US deportations, certain criminal convictions, and travel to or presence in selected countries (currently Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, and Yemen) since 1 March 2011, along with Cuba since 12 January 2021. A "Yes" answer to any of these questions does not automatically deny ESTA but typically routes the applicant to apply for a B-1/B-2 visa through the US Embassy in London instead. Misrepresenting a "Yes" as "No" to obtain an ESTA can lead to a permanent US entry ban.
How long an ESTA lasts and validity rules
An approved ESTA is valid for two years from the date of approval, or until the passport expires, whichever is sooner. During the validity period the ESTA permits multiple visits to the US, with each individual visit limited to 90 days. The 90-day clock starts on each entry and ends on departure; there is no rolling calculation like the Schengen rule.
The ESTA is linked to the specific passport used at application. When the passport is renewed or replaced, a new ESTA must be obtained against the new passport number even if the old ESTA has time remaining. Similarly, certain changes to personal circumstances (name change, change of nationality, certain criminal events) trigger a need to apply for a fresh ESTA against the new circumstances.
The 90-day rule and visa runs
Each US visit on an ESTA is limited to 90 days from the date of arrival. The ESTA cannot be extended in-country; travellers needing longer must leave the US before 90 days and apply for the appropriate visa class for a return. The practice of doing short "visa runs" to Mexico, Canada, or the Caribbean to reset the 90-day clock is well-known to CBP and is increasingly scrutinised; multiple back-to-back 90-day stays raise questions about whether the traveller is using the Visa Waiver Program for de facto residence.
Cost: $21 official versus third-party markup
The total official cost of the US ESTA is $21 USD, comprising a $4 processing fee and a $17 authorisation fee, paid directly to US Customs and Border Protection at esta.cbp.dhs.gov. There is no premium tier, no expedited service, no separate validity tier; every ESTA is the same standard authorisation at the same fee.
A long-standing problem in this market is the proliferation of third-party "ESTA processing" services charging $50 to $100 USD to lodge an application that costs $21 on the official site. These services typically use domain names that mimic the official site (such as "esta-application-usa.com" or "us-esta-online.com") and rank highly in search results for "ESTA application from UK". The third party collects the applicant's details, lodges them on the same esta.cbp.dhs.gov portal, and retains the difference. There is no faster channel, no preferential treatment, and no value-added service. For UK travellers, ESTA expediters are among the clearest examples of pure markup in the visa services market.
Processing time and common refusals
The US CBP target processing time for ESTA is immediate. Most applications return an approval within minutes of submission. A minority of applications enter a "Pending" status that resolves within 72 hours, typically because automated background checks need additional time. CBP recommends applying at least 72 hours before travel to allow for pending status. For most UK travellers a same-day or next-day application is fine, but for any trip with non-changeable flights the 72-hour buffer is the safe minimum.
The most common ESTA refusal reasons are prior US visa refusals or denials of entry, prior US overstays even by short periods, criminal convictions that fall within the relevant categories, and recent travel to one of the listed countries. A refused ESTA is not a permanent block; the applicant can apply for a B-1/B-2 visitor visa through the US Embassy in London using a Form DS-160 application, paying a $185 USD fee, and attending an in-person interview. The visa route handles cases where ESTA is not available.

Frequently Asked Questions
How long does an ESTA application last once approved?
An approved ESTA is valid for two years from the date of approval, or until the passport expires, whichever is sooner. During that validity period the ESTA permits multiple visits to the US, with each individual visit limited to 90 days. When the passport is renewed, a new ESTA must be obtained against the new passport number. The ESTA is linked to the specific passport used at application and cannot be transferred to a different passport.
How long does an ESTA take to process?
Most ESTA applications return an approval within minutes of submission on the official esta.cbp.dhs.gov portal. A minority of applications enter a "Pending" status that resolves within 72 hours, typically because automated background checks need additional time. US Customs and Border Protection recommends applying at least 72 hours before travel to allow for pending status. For trips with non-changeable flights, the 72-hour buffer is the practical minimum.
How much does a US ESTA cost from the UK?
The official US ESTA fee is $21 USD total, comprising a $4 processing fee and a $17 authorisation fee, paid directly to US Customs and Border Protection at esta.cbp.dhs.gov. There is no premium tier, no expedited service, no separate validity option. Third-party sites charging $50 to $100 USD are adding markup over the same government application; the third party lodges it on the official portal and retains the difference as a service fee.
Can an ESTA be extended once you are in the US?
No. The 90-day stay on each ESTA entry cannot be extended in-country. UK travellers needing to stay longer than 90 days must leave the US before the 90 days expire and apply for the appropriate US visa class for a return visit. The practice of doing short visa runs to Mexico, Canada, or the Caribbean to reset the 90-day clock is increasingly scrutinised by CBP; repeated back-to-back 90-day stays can lead to entry refusal at the next attempt.
What is the difference between an ESTA and a US visa?
An ESTA is an electronic travel authorisation under the Visa Waiver Program, available to UK passport holders and 40 other nationalities for short visits under 90 days. A US visa is a stamp issued by a US consulate after a Form DS-160 application and an in-person interview, used for stays longer than 90 days, for work, study, journalism, and for applicants who do not qualify for ESTA. ESTA is faster and cheaper; the visa is more thorough and necessary where ESTA is not available.
What happens if your ESTA is refused?
An ESTA refusal does not permanently prevent travel to the US. The next step is to apply for a B-1/B-2 visitor visa through the US Embassy in London. The visa application uses Form DS-160, costs $185 USD, requires a passport-style photograph and an in-person interview at the embassy, and typically takes several weeks for processing depending on appointment availability. The visa route is designed to handle cases where ESTA is not available due to background factors.
How we verified this
ESTA fees, validity, eligibility, and application procedures were verified against the official US Customs and Border Protection ESTA portal at esta.cbp.dhs.gov, the US Department of State Visa Waiver Program pages at travel.state.gov, and the UK Foreign, Commonwealth and Development Office travel advice for the USA, all checked in May 2026. Restricted-country travel rules for ESTA eligibility were cross-referenced against the Department of Homeland Security Visa Waiver Program Improvement and Terrorist Travel Prevention Act notices. Where guidance differs between sources, esta.cbp.dhs.gov is treated as authoritative for fees and procedures and the FCDO is treated as authoritative for British traveller advice.
