She attended South Hampstead High School and the Institut Francais, later leaving at age 14 to be an actress, singer, and dancer due to the influence of her mother.

After performing in Lady Behave (1941) and Old Chelsea (1943), she changed her professional name to Betty Paul.

She then acted in Bless the Bride (1947), Bitter Sweet (1949), Into the Blue, (1950), The Dish Ran Away, (1951), All for Mary (1954) and And So to Bed (1961).

Their productions include creating the first rural soap opera, Weavers Green, as well as The Probation Officer, and Harriet's Back in Town.
