HHSRS is the evidence base the council uses to classify housing hazards, and its Category 1 threshold is the one that triggers civil and criminal enforcement. Damp and mould, excess cold and falls on stairs are the three hazards that land most PRS landlords in trouble. HHSRS is now being refreshed and the new framework is expected to align more closely with Awaab’s Law timescales.
