At a time when social housing tenants are finding it increasingly difficult to pay their rents, the Holding on Home study, which is funded by the Nuffield Foundation, explores tenancy sustainment in social housing. It focuses on the main cause of tenancy failure: rent arrears. By exploring the behaviours and experiences of tenants and landlords, the research will provide evidence and guidance which will improve landlords’ tenancy sustainment policies and practices, making it easier for tenants to pay their rent and fewer tenancies failing.
