Birds of a Feather - Season 3 Episode 10 -

Sharon faces prosecution by the Social Security since they pay rent for her old flat when she no longer lives there and her lodger is in prison. When she and Tracey visit the flat they find squatters have moved in and the lady next door uses the address to order from a record club without paying. They manage to change the locks whilst the squatters are out but find that Dorien has been using Sharon's experiences as a model for the heroine of her saucy novel.
