Your visa requirements for the UK depend on your nationality, passport type, and travel purpose. Visitors to the UK need an Electronic Travel Authorisation (ETA) if they do not need a visa for short stays of up to six months, or do not already have a UK immigration status. Some nationalities require a Standard Visitor visa before travel.
Electronic Travel Authorisation (ETA)
Since 25 February 2026 the ETA requirement has been fully enforced: visitors without a valid ETA are refused boarding and cannot travel to the UK, unless exempt. Nationals from 85 countries who do not need a visa for short visits must hold an Electronic Travel Authorisation (ETA) before travelling.
An ETA costs £20; the fee increased from £16 on 8 April 2026. An ETA will permit multiple journeys and will be valid for two years or until your passport expires – whichever is sooner. It is recommended that people apply for an ETA at least three working days in advance of travel, this is to take account of the small number of cases which may need further review.
Who Needs an ETA
Citizens from visa-exempt countries must obtain an ETA before travel, including:
- European Union, European Economic Area, and Switzerland citizens
- United States, Canada, Australia, New Zealand
- Japan, South Korea, Singapore, Malaysia, Brunei
- Gulf Cooperation Council countries (UAE, Saudi Arabia, Qatar, Oman, Kuwait, Bahrain)
- Brazil, Argentina, Chile
- Mexico, Costa Rica
British and Irish citizens do not need an ETA, including dual citizens. However, dual British citizens should travel with a valid British passport or Certificate of Entitlement.
Visa-Free Entry to the UK
Once you have obtained an ETA, you can enter the UK visa-free for tourism and business up to 6 months. Citizens from countries including the United States, Canada, Australia, New Zealand, Japan, South Korea, Singapore, and most European nations are eligible for this access.
Unlike the Schengen area, the UK does not apply a 90-day rule: the standard maximum visit for all visa-free nationalities is up to 6 months per entry.
Passport Requirements
Your passport must be valid for the whole of your UK stay. No minimum validity period beyond your departure date is required.
Transit Passengers
Eligible visitors who take connecting flights (transiting) and go through UK passport control need an ETA. Those transiting through Heathrow and Manchester airports who do not go through UK passport control do not currently need an ETA. The Home Office describes this airside exemption as temporary and keeps it under review. Many nationalities need a Visitor in Transit visa for airport connections. Direct Airside Transit Visa (DATV) required for certain countries including Afghanistan, Iran, Iraq, and others when transiting through UK airports.
Who Definitely Needs a Visa
Citizens of most countries including China, India, Russia, Turkey, Philippines, Thailand, Vietnam, and most African nations must obtain a Standard Visitor visa before travel. These nationalities cannot use the ETA system and require a full visa application through a UK visa application center.
