Tom was closest to Liam, with the pair going into business making t-shirts in 2008, along with Paul's widow Carla. After Liam's death in a hit-and-run, Tom carried on with Lad Rags with Liam's widow Maria inheriting her husband's share. The partnership lasted until 2009 when Tony Gordon bought Tom out in order to get closer to Maria.
Tom was first seen on the Street in February 2008 for his cousin, Liam Connor's stag do. He returned in June 2008 and in September of the same year, when Sean Tully made a pass at him. Tom helped Liam and his sister-in-law Carla create a new T-shirt business, Lad Rags. After Liam's death, he helped Liam's widow Maria as they both now owned Lad Rags.
Maria tried to set Tom up with hairdresser Natasha Blakeman but failed as Natasha had a crush on Tony Gordon, and Natasha noticed Tom's crush on Maria. Tony told Tom that Maria knew that he fancied her, and Tony warned Maria away from him. Tony later offered to buy Tom's share of Lad Rags. Tom agreed to this and gave Tony the share, much to Maria's disapproval.
Before leaving Coronation Street, Tom had a fling with Kelly Crabtree as it was her birthday.
In an interview McGinley mentioned that Tom and Liam Connor’s mother’s were siblings.  However, the 60 Years of Coronation Street book later showed that Tom's father Brendan Kerrigan was the brother of Liam's mother Helen.
