The Housing Health and Safety Rating System

The 29 Hazards

The Housing Health and Safety Rating System (HHSRS) assesses 29 housing hazards and the effect that each may have on the health and safety of current or future occupants of the property.

The HHSRS provides a way that hazards can be assessed and the best way of dealing with them identified.

If a hazard is a serious and immediate risk to a person's health and safety, this is known as a Category 1 hazard. If a hazard is less serious or less urgent, this is known as a Category 2 hazard.

As part of preparing your property for Letting ABC undertake a Pre Tenancy Inspection to check your property for hazards within this schedule.

Where hazards are found we will work with the landlord or owner of the property to remove or reduce the hazards.
