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.
