Hamilton first came to notice while performing at the Edinburgh Festival Fringe in the 1970s. In the mid-1970s he sustained himself by taking jobs at Harrods and the Post Office before joining the BBC in 1976.
His early radio work, mostly on BBC Radio 4 included Week Ending, The News Huddlines and The Million Pound Radio Show (with Nick Revell). He has since appeared regularly in Chelmsford 123, Have I Got News for You, The News Quiz, QI, and If I Ruled the World. Hamilton is frequently invited as a panellist on The News Quiz and as a guest panellist on I'm Sorry I Haven't a Clue.
He is the voice of Dr Elephant, the dentist in the children's show Peppa Pig. He was also the original voice of Bob Fish, who is also a dentist, in the cartoon Bob and Margaret. Hamilton is also the voice of Captain Squid, the pirate in the children's show Ben & Holly's Little Kingdom.
On 16 March 2007, he co-presented BBC Radio 4's Woman's Hour programme alongside usual presenter Martha Kearney as part of that day's Comic Relief fundraising activities, after defeating Richard Hammond and Kelvin MacKenzie in a poll.
BBC Radio 4 broadcast the first of a four-part series, Andy Hamilton Sort of Remembers, in October 2017; the series comprised the topics of childhood, politics, the human body, and animals, based on his own personal experiences of them.
Hamilton is 5 feet 2 inches (1.57 m) tall. He has no thumb on his right hand. He joked that it was amputated when he was five "by a surgeon who felt that symmetry was over-rated" to the audience of 'Andy Hamilton Sort of Remembers' on Radio 4 in October 2017.
