Kris & Edwina, Fiona & Jenny and Paul (S04E02)

Kris, a dedicated medical scientist, devotes more than 22 hours each week to maintaining his spotless three-bedroom home in Wakefield. He lends a helping hand to single mother Edwina and her teenage daughter Natalie in Derby, whose house hasn’t seen a deep clean since they moved in nearly a decade ago. Meanwhile, Fiona, a 41-year-old beauty therapist from Bedford living with TOCD, strives to assist married couple Jenny and Paul in Surrey, whose three-bedroom home is cluttered with an overwhelming amount of clothes, toys, and games.
