How`re ye Greenbird and welcome to TK.
Have to agree with Had,I too am in Ireland so cannot guarantee it either, But i have read reports of other people being able to hook it up to an old connection and it worked fine,
From what i understand it seems to be the company policy to take away the set top box they gave to the customer but to leave the connection "live".
As Had said, if you can borrow a box from a mate you will find out in 5 mins.
