One of the first questions visitors ask about London is whether they need a visa, and since 2025 the answer has changed for millions of travellers with the introduction of the UK Electronic Travel Authorisation, or ETA. This guide explains, in plain English, who needs an ETA, who still needs a visa, and how to apply. Because rules and fees change, always confirm the current requirements for your nationality on the official UK government website before you travel.
What is the UK ETA?
The UK ETA is a digital travel permission introduced for visitors who do not need a visa to come to the United Kingdom. It is not a visa, but a pre-authorisation linked to your passport that you must obtain before you travel. It was rolled out during 2025, first to visitors from countries outside Europe and then to European travellers, so most visa-exempt nationalities now need one to visit London and the rest of the UK.
Who needs an ETA, and who needs a visa?
Broadly, if you come from a country whose citizens can currently visit the UK without a visa, such as the United States, Canada, Australia, the countries of the European Union and many others, you now need an ETA rather than a visa for a short visit. Travellers from countries whose nationals require a visa to enter the UK still need to apply for the appropriate visitor visa, and the ETA does not apply to them. Irish citizens do not need an ETA, and anyone who already holds UK immigration status is also exempt. Check your own nationality against the official guidance, as the lists are being updated.
How to apply, cost and timing
You apply for an ETA online through the official UK ETA app or the government website, providing your passport details, a photo and some basic questions. There is a fee, which was increased during 2025, so check the current amount on the official site before applying and beware of unofficial websites charging a mark-up. Most applications are approved quickly, often within a few days, but you should apply well ahead of travel to be safe. Once granted, an ETA typically allows multiple visits over a two-year period, or until your passport expires, with stays of up to six months at a time.
Good to know
Do I need a visa to visit London?
For a short visit, most travellers from visa-exempt countries now need a UK ETA rather than a visa. Travellers from countries whose nationals require a visa still need a UK visitor visa. The safest approach is to check your nationality on the official UK government website, as requirements have changed since 2025.
How much does the UK ETA cost?
The ETA carries a per-person fee that was raised during 2025, so the exact amount is best confirmed on the official UK government website at the time you apply. Be sure to use the official app or site rather than a third-party service, which may add unnecessary charges.
How long does the UK ETA take to approve?
Many ETA applications are approved within a few days, and often much faster, but approval is not guaranteed to be instant. Apply well in advance of your trip rather than at the last minute, so any delay does not affect your travel plans.
