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). Connect the
bundle and use it — no user API keys or gov.uk portal signup.
Using the catalog
- Discover datasets — browse the catalog to see names, titles, and what each file contains.
- Inspect a dataset — open one entry for live metadata: file list, row counts, sizes, and update dates.
- 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
- Enumerate datasets — discover available datasets
- Open dataset metadata — file names, sizes, row counts
- Request a download link — signed URL for a specific file (valid ~60 seconds)
Access model
- End users: connect the bundle and call the tools. No API keys, no gov.uk
account, no per-dataset licence acceptance in the MCPBundles UI.
- Platform: MCPBundles holds the upstream operator API access and has
accepted the required dataset terms on the MHCLG portal. Users inherit that
access through the bundle.
- Download links: short-lived presigned URLs. Call the download-link tool
immediately before fetching a file; do not reuse cached URLs.
- Rare licence_unsigned responses: mean MCPBundles platform onboarding for
that dataset is incomplete — not a user action item. Tell the user downloads
are temporarily unavailable and to contact support@mcpbundles.com. Do not
direct them to use-land-property-data.service.gov.uk to sign licences.
Choosing the Right Dataset
| Question | Dataset |
|---|
| Who owns this property (UK company)? | ccod |
| Who owns this property (foreign company)? | ocod |
| All corporate owners in an area? | ccod + ocod |
| Where exactly are the boundaries of a title? | nps |
| Are there covenants on this land? | res_cov |
| What are the lease terms for this property? | leases |
| Upcoming lease expiries in a portfolio? | leases |
| Foreign investment in UK property? | ocod |
Important Notes
- This API provides metadata and download links only. It does not query individual
records. For sold-price history, comps, and area trends by postcode or address, use
the UK Property Intelligence bundle instead.
- 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.
