Written by contributors experienced in US entry requirements and electronic travel authorisation systems, with a focus on practical guidance for UK passport holders.
Last updated: May 2026
As of 13 May 2026, the US State Department confirmed new guidance on visa bond requirements affecting certain nationalities travelling to the United States — a development that has prompted renewed scrutiny of the broader US entry system. For UK travellers planning trips to the US, the core question remains unchanged: you need Electronic System for Travel Authorization (ESTA) approval before you board, and understanding exactly what it costs and how the process works in 2026 is essential preparation.
The ESTA application fee has not increased this year. The total remains $21 USD, as established by US Customs and Border Protection (CBP). What has shifted is the wider context — expanded screening procedures announced in March 2026 mean that accurate, complete applications matter more than ever.
This guide covers the full cost breakdown, eligibility, the step-by-step application process, and the common mistakes that cause unnecessary problems for UK travellers.

What Is ESTA and Why Do UK Travellers Need It?
Many travellers assume that being eligible for the US Visa Waiver Program means no pre-travel paperwork is required. This is incorrect.
The Electronic System for Travel Authorization — ESTA — is a mandatory pre-travel authorisation for all Visa Waiver Program (VWP) travellers. UK passport holders are among those eligible for the VWP, which permits stays of up to 90 days in the United States for tourism or business purposes without a full visa. However, ESTA approval must be obtained before boarding any US-bound air or sea carrier. Arriving at the departure gate without it means denied boarding — not a correction you can make at the airport.
ESTA is not a visa. The distinction matters. A visa involves a consular interview and a formal stamp or sticker in your passport. ESTA is an electronic travel authorisation, linked digitally to your passport and verified by the carrier and US border officers. It is faster, cheaper, and simpler than a visa — but it is still mandatory, and it still carries conditions.
For a full comparison of how these two systems differ, see our guide on the UK ETA vs visa difference.
ESTA Application Cost in 2026: The Full Fee Breakdown
The ESTA application fee in 2026 is $21 USD per applicant. This fee is set by US Customs and Border Protection and has not changed from the previous year. (Source: U.S. Customs and Border Protection, esta.cbp.dhs.gov)
The $21 total is divided into two components:
- $4 — the travel promotion fee (Electronic Travel Promotion/Broker Fee), authorised under the Travel Promotion Act
- $17 — the ESTA authorisation processing fee
Key payment facts:
- The fee is charged per person, per application — including children
- Payment is accepted by major credit and debit cards only
- The fee is non-refundable, regardless of whether the application is approved or denied
- If your ESTA is denied, the $4 travel promotion fee is still charged; the $17 processing fee is only charged upon authorisation
This fee structure applies to all nationalities eligible for the VWP, including UK passport holders. There is no reduced fee for frequent travellers, family groups, or repeat applicants.
What the fee does not cover:
- US entry fees or customs charges
- Third-party assistance fees, if using an application service
- Any costs associated with a subsequent US visa application, should ESTA be denied
Apply only through the official CBP portal at esta.cbp.dhs.gov or the official ESTA Mobile app. Third-party websites may charge significantly higher fees for the same application. The authorisation itself is the same regardless of which platform processes it — the difference is cost.
Who Is Eligible to Apply for ESTA?
ESTA is available exclusively to nationals of countries participating in the US Visa Waiver Program. As of 2026, the United Kingdom remains a VWP member country. UK passport holders may apply for ESTA provided they meet all of the following conditions:
- Hold a valid, biometric (e-Passport) UK passport — non-biometric and emergency travel documents are not accepted
- Are travelling to the United States for tourism, business, or transit — not for work, study, or long-term residence
- Plan to stay for no more than 90 days per visit
- Have not been refused a US visa or previously denied entry to the United States, unless a waiver has been obtained
- Have not travelled to or been present in Cuba, Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen on or after 1 March 2011 (with limited exceptions for diplomatic or military travel)
- Have not been arrested, charged, or convicted of certain criminal offences
Travellers who do not meet these conditions cannot use ESTA. They must apply for a US non-immigrant visa through a US embassy or consulate, which involves a separate fee schedule and a consular interview.
For UK travellers asking the broader question of what entry documentation they need, our guide Do UK Citizens Need a Visa for the USA? provides the full picture.
How to Apply for ESTA: Step-by-Step
The ESTA application is completed entirely online. There is no postal component and no embassy visit.
Step 1 — Access the Official Application Portal
Go directly to esta.cbp.dhs.gov. Bookmark this URL. Do not search for “ESTA application” and select the first result — third-party sites frequently appear at the top of search results and charge fees well above the official $21.
Step 2 — Create or Access Your Application
First-time applicants create a new application. You will need to enter your passport details exactly as they appear in your travel document.
Step 3 — Complete the Application Form
Provide the following information accurately:
- Full name (as on your passport)
- Passport number, issue date, and expiry date
- Date and country of birth
- Nationality
- Home address
- Contact email address
- Details of your planned travel to the United States (flight or vessel information, US address if known)
- Answers to eligibility questions (criminal history, travel history, health questions)
Every answer must be accurate. Providing false information is a federal offence and will result in denial — and may permanently bar future US travel.
Step 4 — Review and Submit
Check all entries before submitting. A typographical error in your passport number or name will cause a mismatch at the border, even if your ESTA was technically approved.
Step 5 — Pay the Fee
Pay the $21 fee using a major credit or debit card. The system will confirm receipt immediately.
Step 6 — Await the Decision
Most applications receive a response within minutes. However, CBP states that processing can take up to 72 hours. (Source: U.S. Department of State, travel.state.gov) Three outcomes are possible:
- Authorisation Approved — you may travel
- Travel Not Authorised — you must apply for a US visa
- Pending — CBP requires additional review; check back within 72 hours
Step 7 — Confirm Before Travel
Log back in to confirm your authorisation status before departure. Carry your passport number — your ESTA is linked to it electronically. You do not need to print anything, though carrying a confirmation email is sensible practice.
ESTA Processing Time in 2026
The standard processing window is 72 hours, though the majority of applications are resolved within minutes. (Source: U.S. Customs and Border Protection, esta.cbp.dhs.gov)
Delays occur when:
- Application details require manual review
- There are discrepancies between your answers and existing databases
- Your travel history or eligibility questions trigger additional scrutiny
- CBP systems are under high demand during peak travel periods
Apply at least 72 hours before departure. This is not a bureaucratic formality — it is the minimum buffer to allow for a pending decision or any correction required. Applying the night before an early-morning flight is a documented source of denied boarding.
An approved ESTA is valid for two years from the date of authorisation, or until your passport expires — whichever comes first. During that two-year period, you may travel to the United States multiple times without reapplying, provided each individual stay does not exceed 90 days.
What the Recent US Travel Changes Mean for ESTA Applicants
The US State Department published updated guidance on 13 May 2026 relating to visa bond requirements for nationals of certain countries. While this measure targets specific nationalities and does not apply to UK passport holders travelling under the VWP, it reflects a broader pattern of enhanced US border scrutiny in 2026.
Additionally, in March 2026 the State Department announced expanded screening and vetting procedures for visa applicants. (Source: U.S. Department of State, travel.state.gov) Although ESTA applicants are not visa applicants, the same principle applies: the accuracy and completeness of your application matters more than it did in previous years.
This is not cause for alarm. UK travellers have long maintained strong approval rates under the VWP. The practical implication is simple: answer every question truthfully and completely, ensure your passport details are entered exactly as printed, and apply with enough lead time to address any pending status before you travel.
Common ESTA Mistakes That Lead to Problems
Based on real cases, travellers encounter avoidable difficulties through a consistent set of errors:
- Applying through a third-party site without recognising the fee inflation — the authorisation is identical; only the cost differs
- Passport number errors — a single transposed digit creates a mismatch that may not surface until check-in
- Applying on an expired or non-biometric passport — ESTA is linked to the specific passport presented at boarding; renewing your passport invalidates a previous ESTA
- Incorrect travel history responses — past visits to restricted countries must be declared, even if the visit was brief or indirect
- Failing to update ESTA when significant details change — if you are arrested or charged with an offence after approval, the authorisation may no longer be valid
- Assuming one ESTA covers all travel documents — if you hold dual nationality, check which passport you intend to travel on and apply accordingly
- Leaving the application too late — applying within hours of departure with a pending status is a foreseeable and preventable problem
For readers also navigating the UK’s own electronic authorisation system, our post on common UK ETA rejection reasons covers similar patterns on the inbound side.
After ESTA Approval: What to Expect at the US Border
An approved ESTA does not guarantee entry to the United States. This distinction is important.
ESTA authorises you to board a US-bound carrier and seek admission. Final entry decisions rest with US Customs and Border Protection officers at the port of entry. Officers may ask about your purpose of travel, accommodation, funds, and onward travel arrangements. Carry evidence of your return or onward journey.
What ESTA allows:
- Tourism, holidays, and sightseeing
- Short business trips (meetings, conferences, negotiations)
- Transit through the United States to a third country
What ESTA does not allow:
- Paid employment of any kind
- Long-term study (short recreational courses may be acceptable; check with CBP)
- Taking up residence
- Travelling on behalf of foreign media organisations (a separate visa category applies)
Each time you enter the United States on ESTA, the 90-day clock resets. However, CBP officers retain discretion to question travellers who appear to be living in the US on repeated short visits. The same principle that applies to other visa-waiver systems — genuine visitor activity, not extended residence — applies here.

Frequently Asked Questions (FAQ)
Q: How much does an ESTA application cost in 2026?
The ESTA application fee is $21 USD, as set by US Customs and Border Protection. Of this, $4 covers the travel promotion fee and $17 covers the authorisation processing fee.
Q: Has the ESTA fee changed in 2026?
No. The ESTA fee structure of $21 USD has remained unchanged. No official announcement has been made by US Customs and Border Protection indicating a fee adjustment for 2026.
Q: Can UK citizens travel to the US without a visa?
Yes. UK passport holders are eligible to travel to the United States under the Visa Waiver Program, provided they hold a valid biometric passport and obtain ESTA approval before departure.
Q: How long does ESTA approval take in 2026?
Most ESTA applications are approved within 72 hours, though many receive a decision within minutes. Applying at least 72 hours before departure is strongly recommended.
Q: Is ESTA a visa?
No. ESTA is a travel authorisation, not a visa. It permits eligible travellers to board US-bound carriers and seek entry under the Visa Waiver Program, but it does not guarantee admission to the United States.
Q: What happens if my ESTA is denied?
If your ESTA application is refused, you must apply for a US non-immigrant visa through a US embassy or consulate. A denied ESTA does not prevent you from applying for a visa through standard channels.
Conclusion
The ESTA application cost in 2026 remains $21 USD — a fee that has not changed, despite the broader shifts in US travel and border policy taking shape this year. For UK travellers, the Visa Waiver Program continues to offer a straightforward route to short-term US travel, provided the application is completed accurately, through the official CBP portal, and well ahead of departure.
The process is not complicated. What causes problems is inattention: a mistyped passport number, an unanswered eligibility question, or an application submitted the morning of a flight. Treat the $21 fee as the minimum — apply correctly, apply early, and verify your status before you travel.
