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 is a serious and an immediate risk to a person’s health and safety.

  • The proportion of PRS dwellings with a Cat 1 hazard has more than halved over this period – from 30.1% of dwellings in the PRS in 2008 to 14.1% in 2018 (this data was published in the 2018-19 English Housing Survey* published in January 2020). 
  • The gap between the PRS and privately owned accomodation has clearly narrowed over this period, reflecting landlord investment in property.

(*This data was first published in 2020, it is in the 2018-19 English Housing Survey. The table in this report from which the data is drawn is labelled "2018").
