On 8 June 2021, Minchin announced live on air that she would be leaving BBC Breakfast "after the summer", after presenting the show for 20 years (at first as a stand-in host).

In 2006, she toured the country in a converted bus meeting England fans as part of the World Cup coverage for BBC News.

In 2006 and 2007, Minchin was a relief presenter on BBC Breakfast while Kate Silverton covered for main anchor Sian Williams.

In April 2010, Minchin co-presented The One Show for a week alongside Chris Hollins while regular hosts Adrian Chiles and Christine Bleakley were unavailable.

Minchin and Gethin Jones presented the documentary series Crime and Punishment, which began on BBC One on 12 March 2012.

Minchin and her husband previously lived in south London but relocated to Eccleston, Cheshire, in 2012, following the move of BBC Breakfast to Salford.

The crimes occurred in July 2020 during the term of a suspended sentence for stalking Girls Aloud singer Nicola Roberts.
