AreaIn 2014-15, Flintshire was unable to provide data on the number of assessments and resolved hazards.  Therefore, 2013-14 has been used for 2014-15 to provide a more accurate Wales level total.  Care should be taken when using data for Flintshire for 2014-15, and the calculated Wales total in comparison to other years.[Filtered]

General description

The information presented here covers the condition of residential properties, including Houses in Multiple Occupation (HMOs), assessed by local authorities under the Housing Health and Safety Rating System (HHSRS).

The HHSRS is used to determine whether residential premises are safe to live in. It replaced the Fitness Standard in July 2006. Local authorities use the System to determine whether a hazard exists that may cause harm to the health and safety of a potential occupant. Hazards are divided into two categories. Those which score high on the scale (and therefore the greatest risk) are called Category 1 hazards. Those that fall lower down the scale and pose a lesser risk are called Category 2 hazards. Where a condition is classified as a Category 1 hazard the local authority has a duty to take the appropriate enforcement action. If it poses a Category 2 hazard the local authority may take enforcement action.


Data collection and calculation

The information presented here is collected via annual returns from Welsh planning authorities on Hazards & Licences during each year.
