Saxondale

Middle-aged pest-controller Thomas "Tommy" Gregory Saxondale (Steve Coogan) is the survivor of a hostile divorce who now lives with his girlfriend, Magz. Tommy speaks with an East Midlands accent and occasionally refers to his Nottingham heritage, though he and Magz live in Stevenage, Hertfordshire. An ex-roadie, Tommy regards himself as a maverick and a free thinker and takes every opportunity to impart his wisdom to his young assistant, Raymond; most of the time the wisdom he imparts is not quite as sound as he likes to think. In his line of work, as well as pharaoh ants, mice, and occasionally moths, Tommy has to battle with snowboarders, pigeon-loving activists, and people who talk about property prices. Tommy knows his own mind and isn't afraid to speak it; unfortunately, Tommy also has anger management problems, and when those around him don't give him quite the level of respect he feels he deserves, it tends to lead to explosions of temper that result in a few more visits to the anger management course. Tommy is devoted to his Ford Mustang Mach 1, although he drives a much less macho Bedford Rascal for work (from Episode 2 the Rascal is replaced by a Renault Kangoo). Tommy also resents that people often remind him throughout the series that he never toured with Led Zeppelin.

Margaret "Magz" Nith (Ruth Jones) is Tommy Saxondale's girlfriend. She is Welsh and is the proprietor of a shop where she sells "shocking" T-shirts and posters, which she designs herself, often depicting cultural icons smoking drugs. Magz is level-headed and kind, acting as a stabilising influence when Tommy seems on the verge of becoming enraged. She is often seen painting iconic feminine figures such as the Brontë sisters or Joan of Arc topless or in overtly sexual positions. She and Tommy engage in an active and rather kinky sex life.

Raymond Fahy (Rasmus Hardiker) is Tommy Saxondale's assistant and lodger. Thus, while Tommy enjoys talking about himself, training him in the mysterious and deadly art of pest control, and sharing a few life lessons, Raymond has little choice but to listen. The generation gap between Raymond and Tommy is reflected during their discussions about music, cars and life in general. He is very passive and rarely takes life as seriously as Tommy, often nodding or smiling instead of engaging with Tommy and his acolytes. He lives in Tommy's spare room and gets an uncomfortably close view of Tommy and Magz's sparky relationship.

Vicky (Morwenna Banks) is an office manager for the agency that issues jobs to Tommy's Stealth Pest Control. Vicky needles Tommy with her bawdy, passive-aggressive sense of humour.

Introduced in series two, Jonathan (Darren Boyd) lives in the house opposite Tommy Saxondale. An upper-middle class executive, much of the humour is derived from Jonathan's failed attempts to engage and bond with Tommy. He will often try to use 'anti-establishment' language and refer to Tommy's car with names such as "the yellow peril", whilst Tommy pretends to not understand what he is talking about. In most of his appearances, he approaches Tommy outside his house when 'the residents association' have a petty complaint to make about Tommy, such as parking his car on the kerb or playing loud music, although he will often suggest he doesn't agree with them to try keep in Tommy's favour. He always starts conversation with Tommy (although showing an ignorance to Tommy's tastes or knowledge) and then, walking back to his house, clicking his fingers as he "remembers" that he has to tell Tommy about the complaint.

Keanu (Steve Coogan) is a recurring character seen in a number of episodes throughout the series. An unemployed, homosexual drug addict and a squatter, Keanu officially changed his name by deed poll to Keanu Reeves. Overtly flamboyant with a Mancunian accent, Keanu is a stereotype of youth culture, personified by his preference for loud, fast electronic/dance music, an unwillingness to work and a promiscuous and carefree lifestyle. On a number of occasions, Keanu has displayed an unreciprocated liking for Raymond, Tommy's assistant.

Alistair (James Bachman) is the therapist who runs the anger management sessions that Tommy attends. A calm and good-natured man, he frequently finds his patience tested by Tommy's unenthusiastic attitude towards therapy and his disruptive and aggressive behaviour within the sessions. The therapy scenes provide the cold open to each episode; Alistair is rarely elsewhere in the show.
