HM Land Registry Datasets MCP Server

HM Land Registry Datasets

Official UK government bulk datasets covering land and property ownership in England and Wales (the MHCLG "Use land and property data" service).

Using the catalog

1. Discover datasets — browse the catalog to see names, titles, and what each file contains.
2. Inspect a dataset — open one entry for live metadata: file list, row counts, sizes, and update dates.
3. Download — request a time-limited signed link for each file when CSV/ZIP (or spatial) payloads are needed.

Responses wrap payloads in a standard {result, success} shape the tools surface as structured data.

Datasets and Their Columns

ccod — UK Companies That Own Property

Freehold/leasehold titles where the registered owner is a UK company, corporate body, or LLP. Excludes private individuals and charities.

Columns: Title Number, Tenure (Freehold/Leasehold), Property Address, District, County, Region, Postcode, Multiple Address Indicator, Price Paid, Proprietor Name (1) through (4), Company Registration No (1) through (4), Proprietorship Category (1) through (4), Proprietor Address (1-3 per proprietor), Date Proprietor Added, Additional Proprietor Indicator.

Use cases: Corporate property portfolio analysis, beneficial ownership research, company due diligence, geographic concentration of corporate holdings, identifying which companies own property in a specific area.

ocod — Overseas Companies That Own Property

Same structure as CCOD but for non-UK incorporated companies.

Additional column: Country Incorporated (1) through (4).

Use cases: Foreign investment tracking, transparency reporting, anti-money-laundering, sanctions compliance, identifying offshore property ownership.

Relationship to CCOD: Together, CCOD + OCOD give corporate ownership coverage for England and Wales.

nps — National Polygon Service

Geospatial polygon boundaries of registered land titles. Requires GIS software (QGIS, ArcGIS, PostGIS) to process — these are shapefiles, not tabular CSV.

Use cases: Mapping title boundaries, spatial analysis, overlay with planning data, flood risk assessment, land assembly feasibility.

nps_sample — National Polygon Service Sample

Sample extract of NPS data for evaluating whether the full dataset meets a need.

res_cov — Restrictive Covenants

All registered land/property with restrictive covenant entries.

Use cases: Property development feasibility, conveyancing due diligence, identifying covenant restrictions before purchase or planning applications.

leases — Registered Leases

Leasehold entries from the title register recording key details from lease documents. Any lease exceeding 7 years must be registered.

Columns: Title Number, Tenure, Property Address, District, County, Region, Associated Property Description, Associated Property ID, Reg Order, Date of Lease, Term, Alienation Clause Indicator, Premium Price Paid, Other Price Paid Description.

Use cases: Lease expiry analysis, ground rent exposure, enfranchisement research, commercial lease portfolio review, identifying short-lease properties.

File Types

Each dataset provides two downloadable files, updated monthly:

• Full File: {PREFIX}_FULL_{YYYY}_{MM}.zip — complete monthly snapshot
• Change Only File: {PREFIX}_COU_{YYYY}_{MM}.zip — delta since previous month

Prefixes: CCOD, OCOD, NPS, RES_COV, LEASES.

Each dataset also has a public example.csv (15-21 rows) showing column structure.

Open dataset metadata to see exact current file names, sizes, and row counts — these change every month.

Workflow

1. Enumerate datasets — discover available datasets
2. Open dataset metadata — file names, sizes, row counts
3. Request a download link — signed URL for a specific file

Licence Requirements

• ccod and ocod: Downloads are gated by a per-dataset licence on the upstream portal. Until that licence is in place at the platform level, the download endpoint returns a clear licence error instead of a file.
• nps, res_cov, leases: Exploration vs commercial terms are defined on the upstream portal; each dataset has its own licence gate.
• A licence-not-signed response is not a tool failure — it's a signal that the operator-level licence for that specific dataset has not yet been accepted on the upstream portal.

Choosing the Right Dataset

Important Notes

• This API provides metadata and download links only. It does not query individual records. For individual property lookups by postcode or address, use the separate HM Land Registry Price Paid or HM Land Registry Linked Data providers.
• Download files are large (hundreds of MB to several GB). They are CSV data in ZIP archives, not inline API responses.
• Download links are short-lived signed URLs. Generate one immediately before use.
• Data is updated monthly, typically in the first two weeks of each month.
• Tech spec URLs in the metadata link to GOV.UK pages with full column definitions.
