US citizens have needed an ETA (Electronic Travel Authorisation) to enter the United Kingdom since 8 January 2025, alongside Canadians, Australians, Japanese, South Koreans and the other 45 visa-free nationalities. The current fee is £20 (about USD 25 at May 2026 exchange), 72-hour approval for most, and the document covers multiple visits of up to 6 months each over 2 years. Apply directly at gov.uk or in the UK ETA app — any third-party site charging USD 100+ to "facilitate" is a useless middleman. This guide shows the real step by step, the errors that get an ETA refused, and what to do if you do get refused.

The confusion starts because the ETA is not a visa. It is an electronic pre-authorisation linked to a passport, identical in form to the US ESTA or the Canadian eTA. US, Canadian, Australian, Japanese and Korean travelers are still visa-free for the UK — they just now need this prior permission.
The rule activated for US passport holders on 8 January 2025, after 2024 testing with Gulf nationals (Qatar, Kuwait, UAE). On 9 April 2025, the Home Office raised the fee from £10 to £20 — the price in force in 2026.
There is exactly one legitimate channel: gov.uk or the official UK ETA app. Everything else is a middleman taking a margin.
Who needs a UK ETA and since when
TL;DRUS citizens have needed an ETA for the UK since 8 January 2025. Applications opened on 27 November 2024 and the rule applies to every non-European visa-free national — Americans, Canadians, Australians, Japanese, South Koreans, Argentines, Brazilians, Mexicans. EU and EFTA citizens entered the scheme from 2 April 2025.
The ETA covers the entire United Kingdom (England, Scotland, Wales, Northern Ireland) plus Jersey, Guernsey and the Isle of Man. Anyone traveling only to Ireland (Republic, Dublin) does not need an ETA — Ireland is a separate country and maintains its Common Travel Area arrangement with the rest of the world separately.
You do not need an ETA if:
- You hold a valid UK visa (any category)
- You have residence rights or pre-Brexit status
- You are a dual UK national or hold an Irish passport
- You are in air-side transit (you do not cross immigration) at LHR or LGW
You need an ETA if:
- You are a tourist (leisure)
- You travel on business without a UK contract (meetings, conferences, trade shows)
- You visit family or friends
- You study for up to six months (short English-language course)
- You connect land-side (you leave the international area, take another flight the next day)
The most common confusion is transit. If you land at Heathrow and pick up another flight in the same international area without crossing passport control, you do not need an ETA. If you change terminals, retrieve luggage, sleep at a hotel — you do. When in doubt, apply. £20 will not bankrupt you.
