The Data Observatory

The NRLA Data Observatory is a collection of official and other well-established data sources which when combined, provide a narrative of the Private Rented Sector (PRS). The NRLA tracks approximately 45 key data sets which are updated monthly, quarterly and annually. A selection of these appear in these pages.

Our Deep Insight blog provides a regular extension of the analysis which appears here, as well as those datasets which are not published in the Data Observatory section of this website.

The blog pages also features blog posts from other organisations and academics to provide insight on the PRS. Here you can also find more in-depth summaries of our regular reports and surveys.

Chart 1: Proportion of English households with CAT 1 hazards

The 29 HHSRS hazards are classified as Category 1 if a hazard represents a serious and an immediate risk to a person’s health and safety.

  • The proportion of PRS dwellings with a Cat 1 hazard has reduced by almost 60% (57%) between 2008 and 2019. 
  • In 2008, almost one-third (30.8%) of households in the PRS had at least one HHSRS Cat I hazard. In 2019, this proportion had fallen to just 13.2%. 
  • This reduction is slightly better than that of households of owner occupiers over the same period. The proportion of owner-occupied households with these hazards fell 55% over the same period.
