UK ETA application: how much time should you allow before your trip?

Traveling to the UK now requires an Electronic Travel Authorization (ETA) . While the process is quick, it's best to plan ahead. Here's the complete guide to when to apply for your UK ETA in 2025 , with all the useful links to avoid any unpleasant surprises.

1. Official processing time for an ETA

According to the official website of the British government , processing an ETA application can take up to 72 business hours . While some authorizations are issued within hours, there are cases of manual checks that slow down the process.

2. When should I apply for an ETA to the UK?

We recommend making your request at least 1 week before departure . This gives you a margin of safety:

  • In case of error in the form
  • If your application is put on hold for verification
  • To anticipate periods of high demand (summer, holidays, etc.)

Good to know : The ETA is valid for 2 years , or until your passport expires. You can therefore apply several months in advance , even if your trip is not imminent.

3. Why avoid the last minute?

Making your request the day before is strongly discouraged . You risk:

  • A refusal without the possibility of appeal in time
  • Missing your flight or train
  • Having to pay a second emergency request

To avoid these risks, plan ahead.
