Hi,
Written permission is mandatory if you are wanting to cross the border into Northern Ireland. There is a fee of €29 applicable for travelling into Northern Ireland. All you will need to do is inform the agent when arriving and they will be able to process this for you.
I hope this helps.
Many thanks, Louise.
