HHSRS: The Housing Health and Safety Rating System Explained
The Housing Health and Safety Rating System (HHSRS) is the risk-based evaluation tool used by local authorities in England and Wales to assess potential health and safety hazards in residential properties. Introduced by the Housing Act 2004, HHSRS replaced the old Housing Fitness Standard with a more comprehensive, evidence-based approach to evaluating housing conditions.
HHSRS assesses 29 categories of housing hazard, grouped into four main areas: physiological requirements (damp, excess cold, excess heat, asbestos, carbon monoxide), psychological requirements (crowding, entry by intruders, lighting, noise), protection against infection (domestic hygiene, water supply, drainage), and protection against accidents (falls, electrical hazards, fire, collision, structural collapse).
Each hazard is scored based on the likelihood of an occurrence and the probable severity of harm to the most vulnerable potential occupant. This produces a numerical score that places the hazard into one of ten bands, from A (most serious) to J (least serious). Band A to C hazards are classified as Category 1 hazards, for which the local authority has a duty to take enforcement action.
When a local authority identifies Category 1 hazards through an HHSRS inspection, it must take appropriate enforcement action. Options include improvement notices requiring specific works, prohibition orders preventing use of all or part of the property, hazard awareness notices, and emergency remedial action for imminent risks. Category 2 hazards give the authority a power (but not a duty) to act.
For landlords and property managers, understanding HHSRS is essential for maintaining compliant properties. Common Category 1 hazards include excess cold (often linked to poor EPC ratings), damp and mould growth, fall hazards on stairs, fire risks, and electrical safety deficiencies. Proactive maintenance and regular property inspections help identify and address hazards before enforcement action is needed.
Custodia’s property management features support proactive hazard identification through structured inspection templates that align with HHSRS categories, helping property managers identify and address potential hazards before they escalate to enforcement level.
