Open Data Sources for PRS Enforcement

Effective PRS enforcement does not require expensive proprietary databases. The UK government and its agencies publish a wealth of open data that, when combined and analysed, provides powerful enforcement intelligence. For councils operating within the £18.2 million national enforcement fund or their own limited budgets, open data sources offer a way to build evidence-led enforcement without significant procurement costs. This guide covers the most useful open data sources for PRS enforcement teams, explains how to access them, and suggests practical ways to combine them for maximum impact.

HM Land Registry provides several free datasets relevant to PRS enforcement: Price Paid Data: Every property transaction in England and Wales since 1995, including address, price, date, and property type. This helps identify properties that have been purchased and may be entering the rental market. A property bought with a buy-to-let mortgage is almost certainly PRS. UK House Price Index: Monthly updates showing price trends by property type and area, useful for understanding local PRS market dynamics. CCOD (Commercial and Corporate Ownership Data): A dataset of properties owned by corporate entities. Companies owning multiple residential properties are likely PRS landlords and can be cross-referenced against licensing records. Overlapping titles data: Identifies properties with boundary or title issues, which can indicate subdivision. The Price Paid API provides free, real-time access to transaction data. For bulk analysis, quarterly CSV downloads are available from HM Land Registry's Open Data portal.

As covered in detail in our separate article on EPC data for enforcement, the EPC register is one of the most valuable open datasets for PRS teams. Key uses include: - Identifying properties rated F or G for MEES enforcement - Detecting property subdivision (multiple EPCs at one address) - Establishing property characteristics (floor area, construction type, heating) - Flagging missing EPCs for properties known to be privately rented The EPC API is provided by MHCLG and returns structured data. Bulk downloads by local authority area are available quarterly. Both are free.

The Police UK open data portal (data.police.uk) provides street-level crime data updated monthly. This data supports selective licensing evidence bases (one of the six conditions is high levels of crime) and can help identify problem properties. Specifically useful data includes: - Anti-social behaviour reports by location (often linked to problem HMOs) - Criminal damage reports (can indicate poor property management) - Drug offences by location (may indicate properties used for illegal activity, which is a breach of most tenancy agreements and licensing conditions) Crime data should be analysed at the LSOA (Lower Layer Super Output Area) level to build area-based profiles. Where crime concentrations overlap with known PRS areas, this strengthens the case for targeted enforcement. The data is published under the Open Government Licence and can be freely downloaded and analysed.

The Office for National Statistics provides several datasets valuable for PRS enforcement planning: Census 2021 data: Tenure type by area, household composition, overcrowding indicators, and economic activity. The census provides the most accurate picture of PRS concentration at small-area level. Index of Multiple Deprivation (IMD): Ranks every LSOA in England across seven deprivation domains. High deprivation areas with high PRS concentrations are prime targets for selective licensing or targeted enforcement. Nomis: The ONS labour market statistics service provides housing benefit and universal credit data by area, helping identify PRS properties receiving housing support payments. These datasets are all freely available through ONS and DLUHC portals. They require some analytical capability to use effectively, but the insight they provide for enforcement planning is substantial.

The real power of open data comes from combining multiple sources. A practical workflow for a PRS enforcement team: 1. Start with your council tax data to identify likely PRS properties 2. Match against HM Land Registry CCOD to identify corporate landlords 3. Pull EPC data for those properties to check energy efficiency compliance 4. Overlay police crime data to prioritise high-crime areas 5. Check against your licensing database to identify unlicensed properties 6. Use census and deprivation data to build the case for targeted enforcement or licensing schemes When the PRS Database launches in late 2026, it becomes the central hub for all of this intelligence. Until then, councils that build multi-source analysis capability will be best positioned to exploit the PRS Database effectively from day one. Tools for this analysis range from Excel and Power BI (for smaller datasets) to Python and PostGIS (for larger, geospatial analysis). The investment in analytical capability pays for itself through more targeted, efficient enforcement.
