Sale prices get a property identifier from 28 August, and address matching stops being guesswork
By Staff Writer | 27 August 2026
From tomorrow the monthly Price Paid dataset for England and Wales is published with lookup tables carrying Unique Property Reference Numbers and INSPIRE IDs. Anyone who has had to reconcile a sale record against a title, a site boundary or a valuation gains a fixed reference to join them on.
HM Land Registry confirmed the change on 26 August. From 28 August 2026 the two identifiers are supplied in separate lookup tables published alongside the monthly Price Paid dataset, which records residential property sales in England and Wales. The registry says the change responds to customer demand, and that similar lookup tables will be added to its UK Companies data and Overseas Companies data later this financial year.
Why an identifier matters more than it sounds
Price Paid Data has always carried an address. An address is not an identifier. The same house appears as Flat 2, 14 Something Road in one system, 14A in another and Apartment 2, 14 Something Road in a third, and joining two datasets on that string is the sort of work that produces a match rate rather than an answer. Every organisation that has tried to link sale prices to planning records, to council tax bands, to EPC data or to a site boundary has written its own fuzzy matching and lived with what it got wrong.
A Unique Property Reference Number is a persistent number attached to the addressable location itself, allocated through local authority address custodians. An INSPIRE ID identifies a spatial object, which is what allows a record to be tied to a mapped extent rather than to a line of text. Supplying both alongside the sale price means the join is exact, and the same property carries the same number wherever it appears.
As a persistent, unique identifier maintained through local authority address custodians and GeoPlace, the UPRN provides certainty of reference across the property sector, ensuring that different organisations are working with the same property, regardless of how its address appears in their systems.

Who this reaches
The dataset is used by property professionals, researchers, public bodies, lenders and digital service providers, and the registry's stated aim is to make it easier to use alongside mapping tools and location based services. The registry's Deputy Director for Data, Lynne Nicholson, has put the change inside a wider plan to publish its datasets with shared identifiers, beginning with Price Paid and extending to its company and overseas company data in the same financial year.
For work on the development and valuation side, the immediate uses are unglamorous but real. Comparable evidence assembled for a valuation, an expert report or a rating appeal can be tied to the mapped unit rather than to a transcribed address, which makes it checkable by the other side. Sales histories across a site assembled for a viability appraisal stop depending on whether someone typed the flat number consistently. And where a scheme's land assembly has to be evidenced, the same reference runs from the sale record through to the boundary.
One qualification is worth stating plainly. The identifiers are being supplied in lookup tables published beside the dataset, not embedded in the Price Paid records themselves, so a user still has to do the join. What has changed is that the join is now on a number that both sides of it agree on, rather than on a string that neither system controls.
