The Hoarder Next Door is a brand new series about Britain’s growing number of extreme hoarders and their quest to cure themselves with the help of friends and family.

In each episode cameras follow the hoarders as they embark upon a unique six week treatment programme with psychotherapist Stelios Kiosses and his team of expert de-clutterers. The first episode features 55-year-old Nigel Jennings in Liverpool, whose only place to sit at home is his mattress – and even that isn’t completely safe.

Living in the midst of the most extreme hoarding that psychotherapist Stelios Kiosses has ever seen, Nigel hasn’t been inside some of his rooms for over seven years. Will six weeks be enough for Stelios and the team to help Nigel deal with his painful past and eventually start to let go of some of his belongings?
