Conrad was the Chatsworth Estate's local milk-man. He is seen in Series 1 and Series 2.
Veronica would call him over and keep him busy, always while wearing a low cut top that she knew would hold his attention, while Ian stole enough milk for both the Gallagher's and Kev and Veronica.
He is first seen in Episode 2 of Series 1 where he explains the stitched cut on his head, apparantly inflicted by someone named Shirley, when she was sectioned.
