Land Registry Adds UPRNs and INSPIRE IDs to Price Paid Data

From 28 August, HM Land Registry will publish Unique Property Reference Numbers (UPRNs) and INSPIRE IDs alongside its monthly Price Paid Data. This update is intended to improve the accuracy of property matching and sales histories for estate agents and other property professionals.

The Price Paid Data records residential property transactions across England and Wales. Estate agents, portals, lenders, and other property businesses use this information for market analysis and property research. The new addition of UPRNs and INSPIRE IDs will be provided in separate lookup tables.

For estate agents, the main benefit is expected to be more accurate matching of historic sales data. Property databases often rely on addresses, which can vary in formatting or change over time, making it difficult to confirm if different datasets refer to the same property. UPRNs assign a consistent identifier to each property, making it easier to connect historic transaction prices to the correct home and improve the accuracy of property histories shown to buyers and sellers.

The inclusion of these identifiers should also support more detailed market analysis, allowing agents to combine Price Paid Data with other property and location datasets for analysis at property, street, and neighbourhood levels.

INSPIRE IDs serve a different function by identifying spatial land parcels. Developers and investors may use them to connect transaction prices with land boundaries, supporting site analysis, planning, and investment decisions. Lenders could also use the identifiers to improve property matching during valuations, mortgage assessments, and due diligence.

HM Land Registry stated that this change is in response to customer demand and aims to make land and property information easier to connect and reuse. The update is described as a data enhancement rather than a new regulatory requirement. Agencies, portals, and proptech providers that use HM Land Registry data will be able to incorporate the identifiers into their systems from 28 August.
