Nightmare Tenants, Slum Landlords

Ben Reeve from Lewisham Council's Rogue Landlord Unit aims to help Lola, who stopped paying rent 18 months earlier in an effort to get her negligent landlord to deal with her dilapidated flat's many problems. Eviction specialists also come to the aid of Amit, who found himself continuing his late father's battle with a nightmare renter, and 70-year-old landlady Joan, who started receiving unnerving threats from her rent-skipping tenant after she started legal proceedings to get him evicted.

The efforts of north London landlord Franc to evict a tenant withholding rent payments on a property whose boiler mysteriously stopped working whenever the rent was due, and a tenant with asthma who has been forced to sleep on his sofa for two years in a damp flat. Plus, a landlord owed £7,000 in rent discovers her nightmare is not over when she evicts the tenant and gains access to her property.

Margaret tries to get the £20,000 she is owed from a letting agent, Stavros and Emily try to get their house back from squatters, and Peterborough council find 12 people crammed into a category-one fire hazard house.

The story of Lesley and Mark Irwin, who fell foul of a single mother who turned out to be a confidence trickster - she advertised their home as a rental property, and stole deposits from unwitting students hoping to move into the area. Plus, Susan and Gary Bailey, who planned to rent out their buy-to-let investment home in East London and took on an agent to deal with tenants on their behalf. However, after they withdrew from the deal, the couple found themselves locked out of their own property when he changed the locks, and they have been unable to get any help from the police.

Landlord Nicholas Parrington discovers a couple are subletting his house, just months after a previous tenant had turned the property into a brothel, while investors in a community centre for children are aghast when squatters move into their building. In Lewisham, the council's Rogue Landlord Unit raids one of their main streets, on the lookout for slum conditions, illegal overcrowding and criminal activities.

After his tenants refuse to move out, a landlord starts building work around them, while another landlord tries to recover £30,000 in unpaid rent.
