Her producing credits for the BBC include Sandy Welch's adaptation of Our Mutual Friend, A Mug's Game by Donna Franceschild, Nature Boy by Bryan Elsley and series two of Common As Muck, written by William Ivory.
Her credits outside the BBC include two series of Rose and Maloney, written by Bryan Elsley and Peter Flannery and Second Generation, written by Neil Biswas.
William Ivory told The Guardian:
"Both as a script editor and a producer Catherine was something of a rarity in that her primary concern was always to realise the writer's voice before all else. She was a hard taskmaster but her relentless drive to get to the heart of a script or an idea ... or a single scene was invariably predicated by 'What do you want to say?'....
"She bothered with the thorny issues of scheduling, star names and what the broadcasters wanted, only when the heart of the piece had been thus settled."
