UK-Ireland ferry passport rule could catch thousands of travellers by surprise

Holidaymakers planning to travel by ferry between Great Britain and the Republic of Ireland are being urged to check their travel documents before setting sail, after operators announced a significant change to their boarding rules.

From September 28, passengers travelling on affected Stena Line and Irish Ferries services will need to present a valid passport before boarding. The new requirement follows updated UK Border Force rules aimed at improving the accuracy and integrity of passenger information collected before departure.

Which routes are affected?

The change applies to Stena Line’s Holyhead-Dublin and Fishguard-Rosslare crossings, where passengers of all ages and nationalities must present a passport at boarding. On these routes, alternative forms of photo identification, such as driving licences, will no longer be accepted.

Irish Ferries has also confirmed that all passengers travelling between Great Britain and the Republic of Ireland, in either direction, will be required to carry a valid passport. The operator is advising customers to ensure their passport, or Irish passport card where accepted, is valid before arriving at the port.

Common Travel Area rules remain the same

The announcement has caused confusion because the long-standing Common Travel Area (CTA) has not changed. British and Irish citizens still have the legal right to travel freely between the two countries without needing a passport under immigration law.

However, transport operators are entitled to set their own identification requirements as part of their boarding conditions. That means passengers travelling on the affected ferry services may be refused boarding if they do not have the required travel document.

There is also no change to travel across the land border between the Republic of Ireland and Northern Ireland, while Stena Line says its routes via Belfast, Liverpool, Cairnryan and Heysham are unaffected by the new policy.

What travellers should do

Anyone booked to travel after September 28 should check that every member of their party, including children and infants, has a valid passport before leaving for the port.

Ferry operators are contacting customers with existing bookings to explain the new boarding requirements and help ensure passengers are prepared before the rules come into force. For travellers who have previously relied on other forms of photo ID on the affected routes, checking their documents in advance could help avoid an unwelcome surprise at check-in.
