HM Land Registry · Open Data Prototype

A working lab connecting Gateway Surveyors to UK Land Registry data

Six live modules covering the free Price Paid Data, UK House Price Index, INSPIRE polygon and MHCLG EPC Open Data services. Paid services (Commercial & Corporate Data, daily mortgage feeds) will be layered on once the workflows are validated.

Live API

Individual Property and Sales Data

Pull the full Price Paid Data sale history for any postcode. Useful when valuing an individual property and checking comparables on the same street.

Live API

Postcode-area sales trends

Aggregate one or several postcodes by year, property type, new build and tenure. Helpful for stratified comparables and market commentary.

Open module
Live API

Back-book resale screening

Upload a CSV of previously completed valuations. We cross-reference each property against PPD to flag any that have since transacted.

Open module
Live API

UK House Price Index

Pull monthly UKHPI series by region and index a historic valuation forward to today's market — useful for back-book triage and desktop revaluations.

Open module
Live API

INSPIRE polygon datasets

Browse the freehold polygon archives published per local authority, with direct download links and an in-browser GeoJSON site-area check.

Energy Performance Certificates

Look up every domestic EPC lodged at a postcode via the MHCLG Open Data Communities API — current band, SAP score, floor area, age band, tenure and fabric detail.

What this prototype is

A direct, live integration to the free HM Land Registry data services

Every query on this site is made server-side against the public Land Registry Linked Data API for Price Paid Data. No fixtures, no caching layer — what you see is what the public data returns right now under Open Government Licence v3.0.

The intent is to validate three early use cases before commissioning paid data feeds: individual valuations, area trend stratification and back-book screening.

Endpoints in scope (free tier)

Provisioned today; aliased and rate-limited server-side.
