Hazard Awareness Notice

A Hazard Awareness notice advises the person on whom it served that Category 1 or Category 2 hazard(s) exist on the premises which is stated. There are in total 29 hazards [1]. The notice shall also be accompanied by a statement of reasons for deciding to serve such a notice. Provisions as to service are the same as for an improvement notice [2].

The content of the notice is similar to an improvement notice except there are no dates for the work to be started or completed, and no offence is committed if not complied with. A hazard awareness notice is not enforceable therefore there are consequences as such if the hazard awareness notice is not complied with.

However, a local authority would typically inspect the property in the future after serving a hazard awareness notice. If the local housing authority find that the hazard awareness notice has not been complied with, an improvement notice may be served which is enforceable and a criminal offence is committed where an improvement notice is not complied with.

The Housing Health and Safety Rating System (HHSRS or the Rating System) sets out that enforcement officers shall using a hazard scoring system to determine whether a hazard is a category 1 or 2 hazards. The hazard score is a numerical representation of the overall risk from a hazard. It is based on the evaluation of the likelihood of an occurrence and of the probable harm that could result.

You cannot appeal a hazard awareness notice.
