Ann and Adam Massingham's farm is a happy, busy affair: a tumbledown country retreat in which chickens roam, geese loiter and a goat called Charity struts around the outhouse like an Edwardian duchess. Unfortunately, that's where the fairy tale ends. For although the Massinghams' farm is a delightful agrarian idyll, their house is an absolute ruddy disgrace. There's hay in the bedroom, fungus on the windowsills and some sort of dungbased growth on the kitchen floor. Naturally, Kim and Aggie are appalled. "I'm appalled!" honks Aggie, scowling at a mug with black stuff in it. "Dirty beggars!" agrees Kim, as she extracts a cobweb the size of Kent from the sofa. It's a delightfully warm-hearted start to the domestic taskmistresses' latest series. With stentorian disapproval swiftly supplanted by cheery encouragement, the results are so dazzling that even Charity seems stirred.

Kim and Aggie catch up with pensioner Pat Crothers. When they first met Pat, a series of bereavements had left her devastated and the more she hoarded the harder it became to clean.

Is this a sign that she's embraced a new way of life?

Carys Hughes spends all day cleaning at work, which perhaps explains why her own house is so filthy.

Horse-mad Margaret and James Holland tighten the reins on their jam-packed home, which has become so cluttered that it's now an obstacle course for James, who's blind. Kim and Aggie are chomping at the bit to teach them both to be as house-proud as they are horse-proud.

Michelle Jay lives in a maisonette in Kennington, south London, and spends her evenings singing karaoke in bars. Her musty maisonette is by no means glamorous, with dust and dirt lining every surface. Can Kim and Aggie convince the singing sensation that she must take responsibility for her living conditions?
