It has been confirmed by Revenue that its new Customs Roll on-Roll off Service is operational, as administrative procedures for ferry freight kick in following the end of the Brexit transition period.

The service enables transport companies to get a Pre-Boarding Notification (PBN) before the goods they are moving start their journey.

A PBN is needed before a lorry can get onto a ferry to cross the Irish Sea, as the UK is now considered a third country for trade purposes.

This morning ferry operator Stena said that six freight truck loads bound for Ireland have had to be turned away at Holyhead as they did not have the correct references.

In a tweet, the company appealed to freight operators to ensure they had their PBNs ready ahead of check-in for the sailing.
