People taking some ferries between Great Britain and Ireland will soon need to show a valid passport before they board. The new rules begin on 28 September 2026.
At present, passengers are not always asked for a passport. They can often travel with another kind of photo identification. The UK Border Force and ferry companies say the change will help them keep passenger information correct before each trip.
Stena Line will require passports on its routes from Holyhead to Dublin and from Fishguard to Rosslare. However, passengers can still travel without a passport on its services through Belfast, Liverpool, Cairnryan, or Heysham. The company is contacting people who have already booked tickets.
Irish Ferries will require a valid passport on all its routes between Britain and the Republic of Ireland. There are still no passport checks between the Republic of Ireland and Northern Ireland.
British and Irish citizens do not legally need passports to travel between the two countries. This is because of the Common Travel Area, an agreement that has existed for more than 100 years. It also covers the Isle of Man and the Channel Islands.
Even so, transport companies can make passports a condition of travel. Airlines have already introduced similar rules. Aer Lingus joined Ryanair in requiring passports for travel between Great Britain and Ireland in February 2026.
