Overview
- From 25 February 2026, dual British citizens must present a valid UK passport or a certificate of entitlement or risk being denied boarding or entry.
- British and Irish citizens are exempt from ETAs, but dual nationals cannot obtain an ETA on a foreign passport, closing the previous workaround.
- Carriers will conduct pre-departure checks and face penalties of up to £2,000 for inadequately documented arrivals after the enforcement date.
- Practical options include a UK passport (about £94.50 in the UK), a certificate of entitlement (around £589), or an emergency travel document (£125) for a single trip.
- Travellers may enter on a foreign passport up to 24 February; Irish citizens remain exempt, and trade groups warn HGV drivers without visas will also need an ETA.
