Tenants who complain of dangerous or potentially deadly faults in privately rented homes are being let down by councils. When landlords fail to fix hazards - including serious faults that pose an immediate risk to health - councils have a legal duty to act. But the number of times councils use enforcement powers is far lower than the number of reports made. In the last five years 135,687 hazards were recorded, including 42,654 which posed an immediate risk to safety, but council action was only taken on 25,243 occasions, while less than 1% of the registered faults led to a prosecution. The housing charity Shelter said the whole system was ‘a car crash’. The private rented sector is home to 11 million people: many are young professionals who are close to buying, but there are also families and older people who will be renting for many years.
