HM Land Registry Price Paid MCP Server

HM Land Registry Price Paid

Open dataset of 20M+ residential property transactions in England and Wales since 1995.

Data Model

• Transaction Record — price paid, date, property type, estate type, new build flag.
• Address — PAON (primary), SAON (secondary/flat), street, locality, town, district, county, postcode.
• Property Types — detached, semi-detached, terraced, flat-maisonette, other.
• Estate Types — freehold, leasehold.

REST API

Base: http://landregistry.data.gov.uk/data/ppi/

• /transaction-record.json — full transaction records with nested address, price, date.
• /address.json — address-only records (lighter, for discovering postcodes/streets).

Filter params use dot notation: propertyAddress.postcode, propertyAddress.street, etc. All address values must be UPPERCASE (e.g. LONDON, PEAR TREE STREET). Pagination: _page (0-based), _pageSize (max 200, default 10).

SPARQL Endpoint

http://landregistry.data.gov.uk/landregistry/query

Prefixes:

• ppd: <http://landregistry.data.gov.uk/def/ppi/>
• lrcommon: <http://landregistry.data.gov.uk/def/common/>

Useful for date ranges, price aggregations, and cross-field queries the REST API can't express.

Gotchas

• Address values are ALL CAPS — the API is case-sensitive.
• The REST API returns linked data JSON with nested objects (not flat key-value).
• Transaction records include _about URIs — ignore these, focus on pricePaid, transactionDate, propertyAddress.
• _count=yes param returns count of matching records but is disabled for very large result sets.
• SPARQL endpoint accepts output=json for JSON results.
