If you are transporting live animals under an ATA Carnet, you will need to tell Border Force as this will help them to prioritise the processing of your ATA Carnet. When your crossing is confirmed, you will need to let Border Force know when you expect to arrive at Holyhead inland border facility service. You must do this at least 24 hours before you’re due to arrive. Email Border Force at: BFHolyhead@HomeOffice.gov.uk. If you’re a UK trader transporting live animals you’ll need to lodge a travel plan with Defra before you start your journey.
