Andrew is Executive Producer of Objective Productions, a company he established in 1996, which currently produces a wide variety of television entertainment, including The Kevin Bishop Show, Derren Brown, Balls of Steel, Peep Show, The Real Hustle, and Star Stories.

Although Andrew enjoyed a short stint as a child actor, appearing as Tom Brill in The Canal Children in 1976, he made his mark as a children's magician, and won the Magic Circle's Young Magician of the Year prize. He appeared in a number of variety shows on television, and was invited to join the cast of London Weekend Television's Copy Cats show in 1985. The show's main stars, Gary Wilmot and Bobby Davro, left the show during its first series, meaning that O'Connor became one of the lead figures. He was the only member of the cast to write for the show as well as appear in it. His own children's show, Andrew O'Connor's Joke Machine soon followed, in which he told jokes and performed magic tricks and invited children to do the same.

In 1986, he began appearing in ITV's popular Saturday morning children's series, No. 73. But shortly afterwards, he switched to the BBC to launch another Saturday morning children's series, On the Waterfront, alongside fellow ex-No. 73 host Kate Copstick.

In 1988 O'Connor also appeared regularly in short comedy sketches co-written by himself for the Observation round in ITV game show The Krypton Factor. In the same year he took over from Jeremy Beadle as the presenter of the daytime game show, Chain Letters. He returned to acting to play the role of the computer in early 90's children's sci-fi show Kappatoo but it was his career as a quiz-show host that took off, and he subsequently presented the UK version of Talk About, moved to Saturday night prime time in 1991 with One to Win, and returned to daytime television with The Alphabet Game. This latter show was devised and produced by O'Connor.
