With the UK Electronic Travel Authorization (ETA) system rollout, you may wonder, do stopover or transit passengers need one? Do they need to apply for it even if they’re only merely passing through the United Kingdom?
Even non-European travelers are confused about this. In fact, many may assume that if they’re not leaving the airport, then they’re automatically exempt from the ETA. Sadly, this is not always the case.
That being said, let’s clarify these points and cover exactly how the ETA impacts travelers passing through the UK.
What is the UK ETA?
The UK ETA is an upcoming mandatory digital travel clearance for visitors from certain countries. It works much like the U.S. ESTA or Canada’s eTA system.
Specifically, travelers from visa-exempt nations must apply online before entering the UK. To clarify, it doesn’t replace a visa. Rather, it’s for those who don’t normally need one.
Overall, the goal is to improve border security and streamline arrivals. To achieve this, the ETA system screens passengers before they travel, reducing on-arrival risks and delays.
Who Needs a UK ETA?
Many non-European travelers will need an ETA. The system applies to visitors from countries that don’t need visas for short stays.
These are often countries like the United States, Australia, Canada, and Japan. If you’re from a visa-exempt nation, then chances are, you’ll need an ETA. Hence, you’ll need it even if you’re only coming to the UK for a few days—or just passing through.
Stopover vs. Transit
Although the terms “stopover” and “transit” might seem interchangeable, they’re not. And the difference matters.
A stopover usually means a longer layover, possibly involving an overnight stay or leaving the airport. Specifically, travelers may go through border control and enter the country.
Transit, on the other hand, refers to passing through the UK airport without entering the country. You stay “airside,” within the international terminal, and don’t clear customs or immigration. It’s typically a stop between connecting flights lasting less than 24 hours.
Which category you fall into can determine whether you need a UK ETA.
Do Transit Passengers Need ETA?
This is the heart of the issue, and the answer is: it depends.
As of January 2025, the UK has temporarily suspended the requirement for transit passengers.
Hence, if you’re transiting without entering the UK, then you don’t need an ETA. Specifically, this applies if you stay in the international transit zone. But if you pass through UK border control for any reason, even briefly, an ETA becomes mandatory.
So, ask yourself:
- Will you go through UK immigration?
- Will you collect and re-check your bags?
- Will you change airports or terminals?
- Are you staying overnight?
If the answer to any of those is yes, you’ll likely need an ETA.
Here’s a simple rule: if you touch UK soil beyond passport control, you need authorization. The travel requirement applies even if you’re not technically “visiting.” Overall, even a few hours outside the terminal triggers the requirement.
The safest route is to check your itinerary closely and apply if there’s any doubt.
Common Transit Scenarios
Let’s break down real-world examples.
- US to France via London, no terminal change: You’re staying in the international terminal and not going through UK border control. For this, ETA is not required.
2. Overnight layover in London, hotel booked nearby: You’ll enter the UK to sleep outside the airport. In this scenario, ETA is required.
3. Changing airports (Heathrow to Gatwick): This requires you to enter the UK and use ground transport. In such a situation, you’ll need an ETA.
4. Checked baggage needs to be re-checked: You’ll likely pass through customs. As such, ETA is mandatory.
5. Flight delay forces overnight stay: Even if unintended, you must enter the UK. Hence, ETA is necessary.
As a rule, assume any landside movement requires ETA clearance.
Applying for an ETA (If Needed)
Applying for a UK ETA is simple and can be done online. Here’s how:
Step 1: Visit the EVS platform. It simplifies the ETA application process so you can avoid going through complex visa processes.
At EVS, your personal and travel information remains safe and secure with its strict data protection regulations. Moreover, it provides you with expert guidance and seamless support to ensure a stress-free application journey.
Step 2: Upload a passport photo. It must have a plain, light-colored background without any shadows or objects behind you.
Step 3: Upload a scan or photo of your passport information page. Ensure the full passport photo page is inside the frame, including the two lines of numbers and letters at the bottom. Additionally, the passport must be valid for at least six months upon entering and exiting the UK.
Step 4: Provide your personal information:
- Contact details
- Home address
- Employment information
- Citizenship information
- Criminal history, if any
Overall, make sure that the information you provide matches what is on your passport.
Step 5: Review and confirm the information on your application. You can pay using suitable electronic payment methods.
Step 6: Pay the application fee.
Step 7: Receive your UK ETA. You will receive an e-mail with the decision. Next, the ETA will be linked to your passport digitally.
Once approved, your ETA is valid for multiple visits over a two-year period—or until your passport expires.
Even if you’re not visiting the UK for tourism or business, you still need an ETA if your travel involves entry.
