HHSRS Explained: What Landlords Need to Know in 2026

The Housing Health and Safety Rating System (HHSRS) is the primary method used by local authorities in England and Wales to assess health and safety hazards in residential properties. For landlords, understanding HHSRS is not optional — it is a fundamental part of your legal obligations.

What Is HHSRS?

HHSRS is a risk-based evaluation tool introduced by the Housing Act 2004. Unlike prescriptive standards that set minimum requirements, HHSRS assesses the likelihood of a hazard occurring and the severity of potential harm. This risk-based approach means that the same hazard might score differently depending on the property type and its likely occupants.

The 29 Hazards

HHSRS identifies 29 categories of housing hazard, grouped into four main areas:

Physiological requirements — damp and mould growth, excess cold, excess heat, asbestos, biocides, carbon monoxide, lead, radiation, uncombusted fuel gas, volatile organic compounds.

Psychological requirements — crowding and space, entry by intruders, lighting, noise.

Protection against infection — domestic hygiene pests and refuse, food safety, personal hygiene sanitation and drainage, water supply.

Protection against accidents — falls associated with baths, falls on the level, falls associated with stairs, falls between levels, electrical hazards, fire, flames hot surfaces, collision and entrapment, explosions, position and operability of amenities, structural collapse and falling elements.

Category 1 vs Category 2 Hazards

After assessment, each hazard receives a numerical score that places it into one of two categories:

Category 1 hazards (score of 1,000 or above) are the most serious. Local authorities have a duty to take enforcement action when Category 1 hazards are found. This could mean an improvement notice, prohibition order, or even an emergency remedial action order.

Category 2 hazards (score below 1,000) are less severe but still significant. Local authorities have the power (but not the duty) to take action.

Most Common Hazards Found

In practice, the most frequently identified HHSRS hazards are:

- Excess cold — particularly in older properties with poor insulation and inefficient heating systems
- Falls on stairs — missing handrails, steep staircases, poor lighting on stairways
- Damp and mould — often caused by a combination of building defects and inadequate ventilation
- Fire — lack of smoke detection, inadequate escape routes, faulty electrical installations
- Electrical hazards — outdated wiring, lack of RCD protection, damaged sockets

How to Prepare Your Properties

Regular inspections. Do not wait for a local authority inspection. Proactive assessments help you identify and address hazards before they become enforcement issues.

Address damp promptly. Damp and mould are currently under intense scrutiny following Awaab's Law. Respond to tenant reports quickly and document your actions.

Maintain heating systems. Ensure all properties have efficient heating that can maintain 21°C in the living room and 18°C in other rooms.

Keep records. Document all inspections, maintenance work, and tenant communications. Good records are your best defence if a complaint is made.

Using Technology for HHSRS Compliance

Modern inspection platforms like AnyInspect include HHSRS-specific templates that guide inspectors through all 29 hazard categories. The AI-powered scoring helps ensure consistent risk ratings across your portfolio, while video evidence provides an indisputable record of property condition at the time of inspection.
