You will need a UK transit visa if you: Are in transit to another country and have sufficient funds and the intention to travel onwards. Have evidence to prove you can enter that country. Can show that the only reason for your visit to the UK is for transit purposes.

Whether you need a Direct Airside Transit Visa (DATV) for the UK in 2026 depends entirely on your nationality and your destination. Citizens of countries like India, Pakistan, and Nigeria typically need a DATV to transit through London or Manchester, even if they never pass through UK passport control. However, there are high-value "exemption" rules: if you hold a valid visa or residency permit for the USA, Canada, Australia, or the Schengen Area, you can often "Transit Without Visa" (TWOV). For "Visa-Exempt" nationals (like those from the US, Australia, or EU), you do not need a visa, but as of February 25, 2026, you must have a valid UK eTA (Electronic Travel Authorisation) to transit, even if you stay airside. This is a high-value change for 2026 travelers; "No eTA, No Transit." Always check the official GOV.UK "Check if you need a visa" tool 72 hours before your flight to avoid a high-stress "denied boarding" at your departure airport.
