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).
