On the Up is a British situation comedy written by Bob Larbey, about the failure of a millionaire's marriage, and his relationship with his assorted live-in staff. The programme was first broadcast on BBC1 between 4 September 1990 and 2 November 1992. Plot summary Tony Carpenter is a self-made millionaire who turned his South London minicab firm into a successful chauffeur-driven car service. He lives in a large detached mansion in Esher, surrounded by Rolls Royces and BMWs, with a domestic staff who respect him, and whom he adores; Witty and insolent butler/driver Sam (who is also a childhood friend of Tony), acerbic secretary Maggie and cook Mrs Wembley (responsible for the series' catch-phrase of "Just the one", used to respond to the offer of a sherry even if it was her third or fourth). Despite all these advantages, Tony's life is full of conflict: His working-class background and sensibilities make him uncomfortable with the idea of having domestic staff, and in dealing with local snobs. Nothing he does seems to please his snooty wife Ruth, who hates his downmarket behaviour, constantly suspects him of infidelity with either his secretary Maggie or friend & model Dawn (both of whom are significantly younger than herself), and cannot abide the "chummy" relationship he has with "servants". Then there is daughter Stephanie, away from home at a Public School and thus being inculcated with upper / middle class sensibilities, who is embarrassed by both her father's differing outlook, and by the unsettled relationship between her parents. Finally there is his mother, who is still living in a South London terrace, and never seems impressed with his achievements, finding herself unable to understand why he lives "all the way over there" (in reality about 14 miles away) in his big house. The third series ended with Tony looking set to enter a happy relationship with new love interest Jane Webster, a single mother from Stephanie's school, as well as romantic interests for all three staff, but also closes on a slight cliffhanger as it is displayed that Tony and Ruth still share feelings for each other. A fourth series was initially planned, and was mentioned in in-house BBC literature for the Autumn 1993 season on BBC One, but never came to fruition. Cast Regular Dennis Waterman as Tony Carpenter, the lead character, owner of a luxury car hire business in the Surrey "Stockbroker Belt"
