Visa or ETA: the official check
Most visitors need an ETA or a visa, says the UK government. An ETA is usually enough if you come from countries such as those in Europe, the USA, Australia or Canada. If your passport is not on that list, you need a visa. The government's own tool shows what applies to you.
gov.uk warns against websites that imitate government services, and notes that other websites may charge more to apply. Start from gov.uk only.
