Everything You Need to Know About the UK ETA Application Process

If you plan to visit the United Kingdom (UK) soon, you might need an Electronic Travel Authorization (ETA).

By April 2025, all visitors who travel without a visa to the UK will need an electronic travel authorization (ETA).

An ETA is the UK’s new digital travel permit required for individuals who can visit the country without a visa. It is valid for two years and allows multiple short stays of up to six months per visit.

It allows visits to the UK for leisure, permitted business activities, short-term study, and landside transit or passengers who must go through border control when connecting with their onward flight.

Because it is not a visa, applying for a UK ETA is much simpler and faster. The process is online via the UK government website or the UK ETA app. Going to visa offices is unnecessary.

Here’s everything travelers need to know about the ETA application process. 

When to apply for a UK ETA

Travelers must have a valid UK ETA before traveling to the UK. They are strongly advised to apply for one well in advance, at least three days before their trip, to avoid delays or other issues.

Applicants typically receive a decision on their ETA applications, whether an approval or denial, in around three days. 

Many applicants receive the decision within the day of submitting an application, but there are instances when it could take longer than three days. 

Carriers and border officers will not let travelers board a plane, ferry, train, or vehicle bound for the UK without a valid ETA. Those still waiting for an ETA decision will also be denied boarding.

Requirements for applying for a UK ETA

As with any application process, having all the requirements ready beforehand makes it quicker and easier.

Here is a list of what you need to prepare before applying for a UK ETA:

• A valid, biometric passport issued by a country eligible for visa-free travel to the UK. 
• A recent digital passport photo of high-quality
• A valid email address
• A working electronic payment method, such as a credit card, debit card, Apple Pay, or Google Pay

Applying for a UK ETA

First, ensure you are on the official UK government website with a gov.uk URL and only download the UK ETA app from the Apple and Google Play stores.

Complete the UK ETA application process promptly. Your session will expire if you are idle or inactive for 20 minutes.

If this happens, you must restart the process and fill in the required information again. The website or app does not save any previously entered or submitted data during an inactive or canceled session.

Here are the step-by-step instructions on how to apply for a UK ETA online.

STEP 1: Upload or take a photo of the passport you will use to travel to the UK.

An applicant’s passport establishes their identity and nationality. You must have a passport issued by a country with a visa waiver status with the UK or whose citizens can travel to the UK without a visa.

Your passport must also be valid for at least six months or within entry and exit from the UK. Ideally, the passport should be valid for at least two years to maximize the cost of a valid UK ETA.

Ensure that the photo captures all the relevant information on your passport identity page, including your picture and the two lines of numbers and letters at the bottom. Do not use a photocopy of your passport.

STEP 2: Upload a recent passport photo or take a picture using your device’s camera.

It must be a clear, high-quality photo, not a screenshot or photocopy. The photo should also be in full color without any filters or effects. Save your photo as a JPEG file or with the file extension .jpg.

Take a photo similar to a passport photo. Look at the camera with your head straight and your shoulders within the frame. Remove eyeglasses if they cause glare and any head covering unless it is for religious or medical reasons.

The exact photo specifications are required if you are applying for a UK ETA for someone else or children aged 10 and older. Children aged nine and younger below do not require a scan or photo of their face.

STEP 3: Fill in the information needed and answer security eligibility questions.

It is crucial to provide accurate and truthful answers. This includes personal information, employment details, any other nationalities you may have, and those related to security eligibility, such as criminal record and immigration history. 

Here is a list of information applicants must disclose when applying for a UK ETA:

The ETA application form currently does not require travel details or financial requirements.

However, if asked at the border, applicants must be prepared to show proof of the length of their stay in the UK or financial capability to support themselves during their stay and journey home.

STEP 4: Pay for the application.

The UK ETA costs £10 per application and needs to be paid online to complete the application process.

To pay online, you must provide your credit card or debit card number, name on the card, expiry date, and CVV code. You can also input your Apple Pay and Google Pay details to pay.

STEP 5: Submit your application and wait for your UK ETA decision.

Once you have successfully paid for and submitted your ETA application, a confirmation receipt will be sent to the email address you provided.

Upon submission of an ETA application, the system will check if you supplied all the required information. 

It will then automatically cross-verify the data you provided against several security databases in the UK and worldwide to determine whether you are suitable for an ETA.

The Home Office will send updates to the email you provided. It may also request other documents from you to verify your ETA eligibility if necessary. Monitor your email closely and keep your phone lines open to attend to such requests promptly. 

Guidelines for completing the UK ETA application form 

Completing an online application form is as easy as it sounds, but there is much room for errors. Mistakes or omissions in the UK ETA application, whether knowingly or not, can lead to delays in receiving a decision or refusal of your ETA application.

To avoid common mistakes:

• Prepare the documents and necessary information before starting the application process.
• Provide or capture clear, high-quality photos of your passport and yourself.
• Make sure to read all the questions carefully and double-check your answers.
• Check beforehand if your electronic payment method has enough funds and works properly. 

Once you submit your ETA application, you can no longer amend or withdraw it. 

The quickest and easiest way to correct any errors in the application is to submit a new ETA application and pay the fee again. However, this is only recommended if they can be sure to address these errors. 

If the ETA application is denied, you should apply for an appropriate UK visa: a Standard Visitor visa, Transit visa, or Temporary Creative Work visa. 

Applying for a UK visa is more complex and takes longer, so you might need to adjust your travel plans accordingly.  

Other things to consider in your UK ETA application

If granted, the ETA is linked to an individual’s passport, so make sure you travel with the one you used in your application. 

It’s also important to note that a valid UK ETA does not guarantee entry into the UK. Travelers with an ETA must still submit to identity checks at the UK Border. They can still be turned away if they fail an identity check or fulfill other entry requirements.

Travelers are also advised to avoid any legal issues before their trip to the UK. Any run-ins with the law can affect your ETA. 

Even if you have already received an ETA, authorities can still revoke or cancel your permission if new information appears when your passport is scanned at the border. new information appears when your passport is scanned at the border.
