The world of travel is changing, and starting in April 2025, a significant update will affect EU, EEA, and Swiss citizens planning to visit the United Kingdom. If you’re someone who has enjoyed seamless entry to the UK without the need for a visa, it’s time to prepare for a new requirement: the UK Electronic Travel Authorisation (ETA). This new regulation aims to improve border security while ensuring that travelers meet certain entry requirements before arriving.
In this guide, I’ll walk you through everything you need to know about the UK ETA—what it is, who needs it, how to apply, and how it will impact your travel plans. If you’re planning to visit the UK for tourism, business, or even transit purposes, it’s crucial to understand these new rules. Stay ahead of the game, avoid surprises at the airport, and ensure a smooth journey to the UK.

What is the UK ETA?
The UK Electronic Travel Authorisation (ETA) is a new travel requirement for EU, EEA, and Swiss citizens starting in April 2025. It’s an online authorization, and it replaces the previous visa-free entry for short stays. The ETA isn’t a visa, but it’s a travel permission that allows you to board a flight or train to the UK.
Even though the ETA allows you to travel, it doesn’t guarantee entry. Border control officers will still inspect your documents when you arrive in the UK. Think of it as a pre-screening system that ensures you meet certain entry conditions before you reach UK borders.
Once approved, the ETA will be linked electronically to your passport. It’s valid for multiple trips, but each visit can’t exceed six months. The authorization lasts for up to two years or until your passport expires, whichever comes first.
This system is similar to what other countries like the United States use. It aims to strengthen border security by filtering out potential security risks before travelers even board a plane.

Who Needs the UK ETA?
Starting April 2025, the UK ETA is required for citizens from the European Union (excluding Ireland), the European Economic Area (EEA), and Switzerland. If you’re planning to visit the UK for tourism, business, or even just for a short stopover (transit), you will need to apply for the ETA.
However, there are some exceptions. If you are an Irish citizen, you don’t need the ETA. The same goes for anyone who already has a valid UK visa or residency permit. These travelers can continue using their existing documents to enter the UK without needing an ETA.
It’s essential to understand that the ETA applies only to nationals who previously didn’t need a visa. For example, if you’ve been able to visit the UK visa-free in the past, you’ll now need an ETA for future trips.
How to Apply for the UK ETA
Applying for the UK ETA is a straightforward process, but it’s important to plan ahead. You can apply online using the UK ETA app or the government’s official portal. The process requires a few simple steps to ensure that the UK can verify your eligibility before you travel.
Here’s how to apply:
- Visit the Official Portal: Go to the UK ETA website.
- Fill in Basic Information: You’ll need to enter your passport details, including your full name, date of birth, nationality, and contact information.
- Upload a Recent Photo: The UK will require a clear photo for your application. Make sure it meets their guidelines.
- Answer Background Questions: You’ll be asked about your criminal background and any security concerns. These questions are to assess your eligibility to enter the UK.
- Pay the Fee: As of now, the fee is £10. However, it will increase to £16 on April 9, 2025. You must pay this fee online. The payment is non-refundable, so be sure your details are correct before you submit.
Most applications are processed quickly, and you’ll receive approval in minutes. However, in some cases, the approval may take up to three working days or longer if additional checks are needed. Once approved, the ETA will be electronically linked to your passport. You must travel with the same passport that was used to apply for the ETA.
Cost of the UK ETA
The cost of the UK Electronic Travel Authorisation (ETA) is currently £10. This fee allows you to visit the UK multiple times, for up to six months at a time, within two years or until your passport expires—whichever comes first. The fee must be paid during the online application process.
However, be aware that the fee will increase to £16 starting on April 9, 2025. So, if you apply after this date, you will be required to pay the higher fee. It’s important to note that this payment is non-refundable. Whether your application is approved or denied, the fee remains the same.
Keep in mind that every traveler, including children and babies, will need their own ETA. You must pay the full fee for each application submitted. To avoid any confusion, always apply through the official UK government portal or the UK ETA app, as third-party websites may charge extra fees but do not speed up the process.
Arrival at UK Airports with an ETA
Once you have your UK ETA, it’s important to know what to expect when you arrive in the UK. Your ETA essentially acts as your pre-approved travel permission. However, it does not guarantee entry. Upon arrival, you will still need to go through the standard immigration process.
Here’s what you can expect at the UK border:
- Passport Scan: Your passport will be scanned to verify the ETA linked to it.
- Immigration Check: The officer will ask you basic questions about your visit. Be prepared to explain the purpose and duration of your stay. Stay calm and answer honestly to help the process go smoothly.
- Baggage and Customs: After clearing immigration, head to baggage claim and potentially pass through customs. Be aware of customs regulations, such as limits on what you can bring into the country.
Even though the ETA simplifies the entry process, you’ll still need to follow all standard airport procedures. The key takeaway is that your ETA serves as an approval to board your flight, but UK immigration has the final say on entry when you arrive.
Travel Tips for EU Visitors in the UK
To help ensure a smooth trip, here are some travel tips specifically for EU visitors coming to the UK:
- Ensure Your Passport is Valid: Your passport should be valid for the entire duration of your stay in the UK. It’s always a good idea to have some extra months of validity, even though EU passports previously only needed to be valid for the duration of the trip.
- Have Your ETA Approved in Advance: Don’t leave your ETA application to the last minute. Apply well in advance to avoid delays. Make sure the details on your ETA are correct, especially your passport number and name.
- Currency: The UK uses the Pound Sterling (GBP), so you’ll need to exchange your Euros for local currency. You can do this at banks, post offices, or exchange bureaus. Be sure to shop around for the best exchange rates.
- Driving in the UK: If you plan to drive, remember that the UK drives on the left side of the road. You’ll also need to ensure your EU driving license is valid. In most cases, an International Driving Permit is not necessary.
- Public Transportation: The UK has an excellent public transport system, especially in cities. Research travel cards and contactless payment options like Oyster cards in London for convenience.
- Mobile Roaming: Check with your mobile provider for roaming charges. Depending on your plan, it might be cheaper to buy a local SIM card.
- Healthcare: While the European Health Insurance Card (EHIC) was previously useful, it’s now recommended to get travel insurance for medical coverage during your stay. The UK healthcare system can be expensive for visitors, so it’s best to prepare.

Exceptions to the UK ETA Requirement
While most EU, EEA, and Swiss citizens will need to apply for the UK Electronic Travel Authorisation (ETA), there are a few exceptions. These exceptions are designed to make travel easier for people who already have other valid UK immigration documents or fall outside the scope of the new rule.
- Irish Citizens: Citizens of Ireland do not need the ETA to enter the UK. This is because of the Common Travel Area (CTA) arrangement between the UK and Ireland. Irish nationals can continue to travel to the UK using their Irish passport or other travel documents without the need for the ETA. For more information on the CTA, visit the UK Government Website.
- Visa or Residency Holders: If you already hold a valid UK visa or UK residency permit, you don’t need the ETA. Your existing documents will allow you to enter the UK. However, if your visa or residency permit is expired or soon to expire, you will need to renew it before traveling. Check the UK Visas and Immigration page for more details on visa renewal processes.
- Certain Diplomatic or Official Travelers: Diplomats or certain official visitors may be exempt from needing the ETA based on their special status. If you’re traveling on official business, make sure to confirm the exact requirements with the UK embassy or consulate in your country.
What Happens if You Don’t Apply for the UK ETA?
If you fail to apply for the UK ETA before traveling, you could face significant complications. It’s important to understand the potential consequences of not getting your ETA:
- Denied Boarding: Airlines are required to ensure that passengers have the correct travel documentation before they board flights to the UK. If you don’t have an approved ETA, you may not be allowed to board your flight.
- Delayed Entry: If you somehow manage to arrive at the UK border without an ETA, you may be refused entry. Border control officers could delay your entry or even send you back to your departure country if you don’t have the necessary authorization.
- Increased Costs: In case you’re not allowed to board your flight or are sent back at the border, you may face unexpected costs such as flight changes, accommodation, and other travel expenses. Additionally, you would still be required to apply for the ETA and pay the necessary fee.
To avoid these issues, make sure to apply for the UK ETA well in advance. The UK government recommends submitting your application at least a few days before your planned travel, though many applications are approved within minutes through the official UK ETA Portal.
How to Prepare for UK Border Control
Having the right documents and being prepared for UK immigration will make your journey smoother. While the UK ETA simplifies entry, you still need to follow standard border control procedures when you arrive.
Here’s what to keep in mind when going through UK border control:
- Have Your ETA Ready: Your ETA will be linked to your passport. Ensure that your passport is valid for the duration of your stay and that the details on your ETA match the information in your passport.
- Answer Immigration Questions Clearly: Be ready to answer questions from the immigration officer about the purpose of your trip. This could include why you’re visiting, how long you plan to stay, and where you’ll be staying.
- Know What You Can Bring: Make sure you’re aware of the UK’s customs regulations and prohibited items. Items such as certain foods, plants, and medicines may have restrictions. For more on what you can and cannot bring, check out the UK Border Control Guidelines.
- Be Prepared for Baggage Inspection: After passing through immigration, your baggage may be checked at customs. Be aware of the UK’s customs limits on items like alcohol, tobacco, and gifts. For a comprehensive guide on customs allowances, visit the UK Customs page.
What to Do if Your ETA is Denied
Sometimes, a UK ETA application can be denied. If this happens, don’t panic. There are steps you can take to resolve the issue.
- Check for Mistakes: The most common reason for a denial is incorrect or incomplete information on the application. Double-check your details, including passport number, travel dates, and personal information. If there’s an error, correct it and reapply.
- Appeal the Decision: If your application is denied due to something more serious, such as a criminal record or ineligibility, you may be able to appeal the decision. The UK government provides a process for appeals. For detailed instructions on how to proceed, visit the official UK Visas and Immigration appeals page.
- Apply for a Visa: If your ETA is denied and you cannot resolve the issue through an appeal, you may need to apply for a UK visa. A visa will allow you to enter the UK, but it’s a longer process. You can check visa options and apply through the UK Visas and Immigration website.
In any case, make sure to act quickly to avoid delays or missing your travel plans.

Stay Informed About Future Changes
The UK’s travel rules may evolve over time. It’s important to stay updated about any changes that might affect your travel plans.
- Check for Updates Regularly: The UK government may revise the UK ETA system or introduce new requirements. To stay informed, regularly visit official government websites such as the UK Government or the UK Visas and Immigration page.
- Set Reminders: Set a reminder to check for updates if you’re traveling in the coming months. Any changes to visa policies or entry requirements can affect your trip. Keeping an eye on the latest news will ensure that you don’t miss any critical deadlines.
- Subscribe to Alerts: Consider subscribing to travel alert services provided by official government or travel advisory websites. This way, you will be notified directly about new regulations, fees, or travel guidelines.
By staying informed, you can ensure a hassle-free experience, whether you’re planning a quick visit or a longer stay in the UK.
