Power's most notable television role has been her portrayal of Christine Hewitt in the BBC soap opera "EastEnders". Power was offered the role by one of the programme's producers, Leonard Lewis, for whom she'd worked with previously on "Juliet Bravo" and "Softly, Softly". She has commented "I got a call out of the blue asking if I could go up to the BBC at Elstree to meet him. Mrs Hewitt was going to be in five episodes and I thought, 'wonderful'." Mrs Hewitt made her first appearance on-screen in February 1992, as a lonely divorcee who employed the long running character, Arthur Fowler (Bill Treacher), to tend to her garden—used as a plot device to rebuild Arthur's relationship with his son Mark Fowler (Todd Carty), while they worked together on Christine's garden. Power filmed her scenes for the five episodes and thought that would be the end of it; however, she was subsequently contacted by Leonard Lewis and asked to reprise the role. Power commented "It was all I could do to stop myself screeching down the phone. They didn't tell me which direction the story was going to take. I got on so well with Treacher from the word go. We really liked each other." Mrs Hewitt was reintroduced in a storyline that saw her become Arthur Fowler's mistress, but when the affair ended Power left the series, making her final appearance on-screen in October 1993.
