Consumer champion Matt Allwright joins the ranks of Britain's housing officers on the front line in the battle between landlords and tenants. Matt Allwright joins housing officers in Peterborough, where an estate inspection reveals how illegal fly-tipping is blighting the lives of residents. We meet two families in Wiltshire who are looking to change their lives by swapping their homes. In Stroud, a newly vacated property reveals an alarming colour scheme, and in Newcastle, housing officers investigate whether one of their tenants has been a victim of a garden land-grab. Matt also meets a 91-year-old resident in Aylesbury who is hoping to face a warmer winter now her coal fire has been swapped for radiators.
