The United Kingdom’s Electronic Travel Authorisation (ETA) is a digital pre-travel clearance system introduced to enhance border security and streamline entry procedures for visitors from visa-exempt countries. Launched in phases beginning in 2023, the ETA became mandatory for eligible non-European travellers from 8 January 2025 and for European nationals from 2 April 2025. It applies to individuals visiting the UK for tourism, business, short-term study, or transit, allowing stays of up to six months per visit. The ETA is valid for two years or until the traveller’s passport expires, whichever comes first.

Applying for an ETA is a straightforward online process, accessible via the official UK government website or the UK ETA mobile app. Applicants must provide personal details, passport information, a photograph, and answer security questions. While the ETA grants permission to travel to the UK, it does not guarantee entry; final admission is determined by UK border officials upon arrival. Exemptions from the ETA requirement include British and Irish citizens, individuals with UK visas or settled status, and certain categories of travellers such as children on specific school trips .
