It depends on your nationality. US, EU, Australian, Canadian, and Japanese citizens need a UK Electronic Travel Authorisation (ETA), which costs £20 and is generally approved within minutes via the UK ETA app or gov.uk. Citizens of India, China, Nigeria, Kenya, South Africa, and most of Africa, South Asia, and the Middle East need a Standard Visitor Visa (around £135) arranged in advance through a UK Visa Application Centre.

A UK ETA is valid for two years from the date of approval, or until your passport expires (whichever comes first), and allows multiple visits of up to 6 months each. It is a travel permission, not a guarantee of entry — a Border Force officer still decides admission on arrival.

If your flight is cancelled, you're generally entitled to a refund or free rebooking under the airline's conditions of carriage, and UK-retained air passenger rights rules apply to flights departing the UK or operated by a UK/EU carrier. Contact your airline immediately and keep all receipts for any additional costs, which may be recoverable. Triwize's 24/7 support team can assist with rebooking and claims for bookings made through our platform.
