Spencer's initial work as a governess at a private school helped fund drama lessons, which led to appearances at the
Theatre Royal, Nottingham. She also wrote monologues for after-dinner entertainment, as well as satirical material for radio programmes. During the
Second World War she worked in the Nottingham City treasurer's office before joining a theatre company and, later
BBC Radio, appearing on programmes such as ''
Children's Hour and Dick Barton: Special Agent before The Archers'' began in 1950. In 1953, she left the cast to look after her family, and the role of Peggy was taken over by
Thelma Rogers. Spencer later twice returned to the series to play another character, Rita Flynn, firstly from 1956 to 1958 and again from 1961. In 1962, Rogers left
The Archers to return to the stage, and Spencer returned to the role of Peggy. Her retirement from
The Archers, at the age of 103, was announced by the
BBC on 8 August 2022. Her former co-star
