In 2026, eligibility for the e-gates (automated passport gates) at London Heathrow has expanded but is now strictly tied to the Electronic Travel Authorisation (ETA) system. You can use the e-gates if you are a citizen of the UK, EU, USA, Canada, Australia, New Zealand, Japan, Singapore, or South Korea, and are aged 10 or older (children 10-17 must be accompanied by an adult). Importantly, as of February 25, 2026, all non-visa nationals must have a valid digital ETA linked to their biometric passport to be granted entry via the gate. If your passport is damaged, if you are traveling on a national ID card (for EU citizens), or if your ETA hasn't been properly synchronized, you will be redirected to a manual border officer. For those who meet the criteria, the e-gates remain the fastest way to clear immigration, typically processing a passenger in under 30 seconds, provided they have a "biometric" symbol on their passport cover and a valid digital authorization on file.
