Output fields

Transaction records (record_type: "transaction")

INSPIRE polygon records (record_type: "inspire_polygon")

Returned when includeInspirePolygons is true and the postcode is provided. Each record is a registered title boundary from the HMLR INSPIRE Index.

Note: INSPIRE polygon data may not be available from cloud environments due to government IP restrictions. When unavailable the actor skips silently and still returns all transaction records.

Inputs

At least one of postcode or address must be provided.

Notes

• Registration lag: New build prices may appear several months after exchange — HMLR registers on legal completion, not on exchange of contracts.
• England and Wales only: Does not cover Scotland (Registers of Scotland) or Northern Ireland (LPSNI).
• Historical data: The dataset goes back to January 1995 for residential properties.
• Additional Price Paid (APP) transactions are included alongside standard transactions. These are sales that fall outside the standard residential categories (e.g. repossessions, right-to-buy).
