Not Going Out sofa watching television or at the local pub with his best friend, Tim Adams (Tim Vine), whom he has known for 15 years. Tim is an accountant from Henley-on-Thames who owns the flat in which Lee is a lodger. He is also noted for his cheeky wit and for having a very troubled relationship with his father, with whom he shares many traits and who openly mentions that Lee was unplanned and resulted in the end of his marriage. Very often, the only thing that can get Lee off his couch and active is his efforts to impress the girl
Not Going Out spent ten years living in Switzerland, much to Tim's annoyance. Lucy shares Kate's feisty nature and quick wit, and her interaction with Lee is very similar. Although his frequent laziness annoys her, Lucy appears to enjoy Lee's presence in the flat, largely because of his company and his willingness to help her out of an awkward situation. Tim soon finds himself drawn into Lee's many schemes to impress Lucy, most of which backfire, fail to impress her or land them in trouble. Very often, Lee finds himself confiding in his friend, Barbara (Miranda Hart), the cleaner, about his many problems.
