Moving a friend to Ireland from the UK (and then returning)

Hi All,

I need some help, my friend needs to move to Dublin next weekend, latest 2 weeks. Everything is sorted except actually physically getting there.

They have enough stuff to fill a car and I have offered to drive them over, little holiday for me!

We are a little confused on the process of bringing their stuff in. Am I right in thinking that we just go to customs when we arrive at the ferry port with the declaration C&E or do we need to send that for 2 weeks before?

With the As it will all be personal belongings in a vehicle that is returning to the UK?
