UK Implements Stricter Entry Rules with Mandatory ETA System from February 2026
The Home Office has announced that the United Kingdom will fully enforce its Electronic Travel Authorisation (ETA) system from February 25, 2026, marking the end of the current "soft launch" period. This implementation introduces a strict "no permission, no travel" policy that will be rigorously enforced by all carriers, including airlines, ferry operators, and rail companies.
Mandatory Requirements and Fee Increases
From the enforcement date, all eligible visitors without a valid ETA will be denied boarding by transportation providers. This requirement specifically applies to visa-exempt travellers, encompassing citizens from numerous countries such as the European Union, United States, Canada, and Australia. The Home Office has confirmed an upcoming fee increase, with the cost of an ETA rising from £16 to £20 in the near future, though an exact date for this hike remains unspecified. This change follows a previous increase from £10 to £16 implemented in April 2025.
Validity Period and Transit Rules
Once granted, an ETA remains valid for two years or until the holder's passport expires, whichever occurs first. The authorisation permits multiple entries into the UK for stays of up to six months at a time. For travellers transiting through the UK, those taking connecting flights who pass through passport control (landside transit) must possess a valid ETA. Currently, passengers transiting "airside" through Heathrow or Manchester airports without passing through border control are exempt from this requirement.
Significant Changes for Dual Nationals
A notable alteration affects dual British citizens, who can no longer use a non-British passport to enter the UK without either an ETA or a Certificate of Entitlement. The Home Office strongly advises dual citizens to travel exclusively with a valid British passport to prevent potential boarding denials. Exemptions from the ETA requirement include British and Irish citizens, along with individuals holding valid UK visas or status under the EU Settlement Scheme.
Application Process and Security Objectives
Most ETA applications submitted through the official UK ETA app are processed within minutes, but the Home Office recommends applying at least three working days before travel to accommodate any necessary manual checks. The government asserts that the ETA system, comparable to the United States' ESTA program, is crucial for digitising border controls and identifying potential security threats before they reach UK territory.
