The article explores, via desk-based research, supplier-generated changes to security of tenure for three household categories. The article concludes that to varying degrees across all tenures, supplier-generated precarity is evident in respect of access, security and supply. This supplier-generated precarity is the outcome of flawed policy assumptions and expectations on the part of the state, which has abandoned its commitment to direct social housing provision and market intervention.
