In 1986 Kate formed her own theatre company, Character Ladies, which performed at the Oval House.

One of her first commissions was to ask Joyce Halliday to adapt Isabel Miller's cult lesbian novel Patience and Sarah for the stage. In the following year she took over as programme director there, overseeing a wide range of work, both producing inhouse and welcoming touring companies with groundbreaking women's, lesbian and gay, and experimental work. In 1980 she went to the Oval House in Kennington, south London, as a freelance director. For some time, Kate was the artistic director of the Writers' Theatre Company at Birmingham Arts Lab. One of their productions was Michelene Wandor's Aid Thy Neighbour (1978), which was among the first plays to deal with artificial insemination and lesbian motherhood.

In 1977 she was a co-organiser of the Women's festival at the Drill Hall in London, and in the same year she formed the Women's Project Company with Nancy Diuguid, to encourage and support female writers. From 1975 to 1978 Kate was involved with, and directed for, the Gay Sweatshop theatre company, and she also established the separate Gay Sweatshop Women's Company.
