Travelling without a UK ETA in 2025: what are the risks and penalties?

Since the introduction of the ETA for visitors from certain countries, this electronic authorization has become essential. In 2025, traveling to the United Kingdom without an ETA could have serious consequences, both upon departure and arrival. Here are the main risks.

1. Denied boarding at the airport

Even before you board the plane, airlines systematically check your travel authorization.

Without a valid ETA, you will be denied boarding and your ticket will be lost.

2. Refusal of entry into British territory

Even if you manage to board, British immigration authorities may refuse you entry.

You will be returned to your home country at your own expense.

3. Administrative and legal consequences

An attempted illegal entry may result in:

  • a temporary or permanent ban from British territory
  • a report to the immigration services
  • prosecution or financial penalties in certain cases

4. Impact on future visa or ETA applications

A history of refusals can complicate your future requests:

  • extended processing time
  • automatic refusal depending on the case
  • need to provide additional supporting documents

5. Good practices to avoid these risks

  • Apply for your ETA at least one week before departure
  • Use the correct passport when applying
  • Keep a digital and paper copy of the authorization
  • Follow the conditions set out on the UK government website

6. Frequently Asked Questions (FAQ)

What happens if I don't have an ETA at the airport?

You will not be able to board. Airlines are required to verify the validity of your ETA before check-in.

Can I enter the UK with a different visa or document?

The ETA is mandatory for nationals of certain countries. If you are affected, no other document replaces the ETA unless you have an official visa or residential status.

Does a minor child also need an ETA?

Yes. Everyone, whether minor or adult, must have their own ETA to travel to the UK.

Can I get an emergency ETA at the airport?

No. The ETA must be applied for online before travel. There is no emergency service at the airport.

Is it possible to challenge a refusal of entry due to the absence of an ETA?

No. There is no appeal process. You will need to apply for a valid ETA and arrange a new trip.
