HM Land Registry reported on 26 August 2026 that it planned to provide Unique Property Reference Numbers (UPRNs) and INSPIRE IDs in separate lookup tables alongside the monthly Price Paid Data dataset from 28 August 2026. The release said the identifiers would apply to datasets published from that date onward and would not be available for previously published datasets.

According to the release, Price Paid Data covers residential and commercial property sales in England and Wales lodged with HM Land Registry for registration in that month, subject to exclusions. The agency said the lookup tables were intended to help link sale price information with mapping tools and other location-based datasets, responding to customer demand. A UPRN identifies an addressable location, while an INSPIRE ID identifies a mapped land or property polygon.

The report also said HM Land Registry planned to add similar lookup tables to its UK Companies and Overseas Companies data later in the financial year. Deputy Director for Data Lynne Nicholson was quoted describing the identifiers as part of a plan to unlock value from land and property data; these aims are the agency's own stated plans rather than confirmed outcomes.
