The private rented sector is an important part of our housing market, housing 4.5 million households in England. The proportion of tenants in the private rented sector living in non-decent housing fell from 47 per cent in 2006 to 28 per cent in 2015. Local authorities have strong and effective powers to deal with poor quality unsafe accommodation and we expect them to use those powers. Under the Housing Act 2004, they can issue an Improvement Notice or a Hazard Awareness Notice if they find a defect in the property. In extreme circumstances, the local authority may prohibit that property from being rented or decide to make repairs themselves and claim the cost back from the landlord.
