Who Needs a UK ETA and How Do You Apply?

The UK ETA is a digital travel authorisation that visa-exempt nationals need before travelling to the UK — including Americans, Europeans, Australians and Gulf nationals. It costs £20, is usually decided within minutes, and once granted lasts about two years (or until your passport expires) for unlimited short visits. British and Irish citizens do not need one.

Who Needs a UK ETA and How Do You Apply?: questions people actually ask

Do US citizens need an ETA for the UK?

Yes — Americans are visa-exempt, which is exactly the population the ETA covers. It costs £20 and lasts about two years.

Do Europeans need an ETA for the UK?

Yes — EU nationals need an ETA for short visits to the UK, a consequence of Brexit that surprises travellers who last visited years ago.

Does an ETA guarantee entry to the UK?

No — it authorises travel. A border officer can still refuse entry, exactly as with any visa-free visit.

Who needs an ETA — and who does not

Everyone visiting the UK for up to six months who does not already hold a UK visa or UK immigration status. That includes visa-exempt Europeans, Americans, Canadians, Australians and others who never needed paperwork for Britain before. You do not need one if you hold a British or Irish passport, a UK visa, or settled or pre-settled status. Transit passengers airside are outside the scheme, but if your connection clears UK border control, that is an entry and needs an ETA.

How to apply, and how long it takes

Apply through the official UK government app or the gov.uk service: passport photo page scan, a face photo, a few eligibility questions, £20. Most decisions arrive within minutes, though the official advice is to allow up to three working days. It is linked to your passport electronically — airline check-in systems verify it, so apply before booking flights if your passport is close to expiry, since the ETA dies with the passport.

The mistakes that cost people their trip

Applying through lookalike third-party sites that charge markups (use gov.uk), leaving the application to check-in day, and assuming an ETA is a visa — it authorises travel, not work or long stays. And the detail that catches families: each traveller needs their own ETA, including children.
