UK ETA for Transit Passengers: A Complete 2025 Guide

If you are passing through the United Kingdom on your way to another country, you might be wondering: Do transit passengers need a UK ETA (Electronic Travel Authorization)?
This guide covers everything you need to know about the UK ETA for transit passengers in 2025 — including eligibility, requirements, and application tips.

Do Transit Passengers Need a UK ETA in 2025?

Yes, in most cases, transit passengers from ETA-required countries must have an approved UK ETA before traveling, even if they do not leave the airport.
There are two main types of transit in the UK:

1. Airside Transit – You remain in the international transit area of the airport and do not pass through UK border control.

2. Landside Transit – You pass through UK border control to change airports or stay overnight.

For both types, if your nationality is on the ETA-required list, you will need to apply for and receive ETA approval before travel.

Who is Exempt from the UK ETA for Transit?

You may not need a UK ETA if you:

• Are a citizen of a country that does not require an ETA or visa for UK entry

• Hold a valid UK visa or residence permit

• Have certain exemptions under international agreements

Always check the UK Home Office website or official sources to confirm your status.

UK ETA Requirements for Transit Passengers

When applying for your UK ETA as a transit passenger, you will need:

• A valid passport from an eligible country

• Your travel itinerary (with onward ticket details)

• A valid payment method for the ETA fee

• Basic personal and security information

How to Apply for the UK ETA as a Transit Passenger

1. Check your eligibility on the UK government’s official ETA page

2. Prepare your documents (passport, travel details, payment)

3. Submit the online application via the official UK ETA portal

4. Pay the ETA fee using a debit or credit card

5. Receive your ETA approval by email (usually within 48–72 hours)

Processing Time & Validity

• Processing Time: Most applications are processed within 3 days, but apply at least 2–4 weeks before travel for peace of mind

• Validity: The ETA is valid for 2 years or until your passport expires, whichever comes first — allowing multiple transits within that time

Important Tips for Transit Travelers

• Apply early to avoid last-minute issues

• Check connecting flight times to ensure you meet UK transit rules

• Know your transit type (airside or landside) to avoid confusion at the airport

• Keep your ETA approval email handy in case airline staff request proof before boarding
