Aldred has presented and sung in several BBC Schools Radio series, including "Singing Together", "Music Workshop", "Time and Tune" and "Music Box". She has also performed on radio and in the theatre. She has also reprised her role as Ace in the 1993 thirtieth-anniversary charity special "Dimensions in Time" and, since 1999, the "Doctor Who" audio plays produced by Big Finish Productions. Following the start of rumours in 1994 and 1995, avid "Doctor Who" fans expressed hope that Aldred would reprise her role in the project that would become the 1996 "Doctor Who" television movie, but she did not appear, and her character's fate was not mentioned.
