The check returns the registered titles (land and property) whose proprietors include the company, together with each title's address, tenure, price paid and full list of proprietors. The data comes from the HM Land Registry dataset of UK companies that own land, published monthly. `dataset_month` in the response shows which monthly release the result is based on. > [!NOTE] > > The check covers companies registered in the UK. Properties owned by overseas companies are not included. ## Step 1: Create an applicant Create an applicant to associate the verification with. > [tab] Curl > > ```bash theme={null} > export API_KEY= > > curl -H "ds-api-token: $API_KEY" \ > -H "Content-Type: application/json" \ > -X POST "https://api.dataspike.io/api/v3/applicants" \ > --data '{"external_id": "company-456", "applicant_type": "Organization"}' > ``` > > Response: > > ```json theme={null} > { > "id": "01827ed4-c928-7a3c-9a30-7ab7cc169d11" > } > ``` > [tab] Python > > ```python theme={null} > import requests > > API_KEY = "" > BASE = "https://api.dataspike.io" > HEADERS = {"ds-api-token": API_KEY, "Content-Type": "application/json"} > > resp = requests.post(f"{BASE}/api/v3/applicants", headers=HEADERS, json={"external_id": "company-456", "applicant_type": "Organization"}) > applicant_id = resp.json()["id"] > ``` ## Step 2: Submit land registry check request Provide the company's Companies House number. Only the company number is accepted. If you only know the name, get the number with the [UK Company Registry Check](https://docs.dataspike.io/kyb-verification/uk-registry-check.md) first. Unlike the other KYB checks, this one is synchronous: the response already contains the result, so there is nothing to poll. > [tab] Curl > > ```bash theme={null} > APPLICANT_ID="01827ed4-c928-7a3c-9a30-7ab7cc169d11" > > curl -H "ds-api-token: $API_KEY" \ > -H "Content-Type: application/json" \ > -X POST "https://api.dataspike.io/api/v4/kyb/$APPLICANT_ID/uk-land-registry-check" \ > --data '{"company_number": "01234567"}' > ``` > > Example response (HTTP 200, verified): > > ```json theme={null} > { > "request_id": "019c9e79-4d64-73e1-9f30-5374f0f57975", > "status": "verified", > "verification_type": "uk_land_registry_check", > "response_data": { > "dataset_month": "2026-11", > "total_count": 2, > "titles": [ > { > "title_number": "LN123456", > "tenure": "Freehold", > "property_address": "10 High Street, London (EC1A 1AA)", > "district": "CITY OF LONDON", > "county": "GREATER LONDON", > "region": "GREATER LONDON", > "postcode": "EC1A 1AA", > "multiple_address": false, > "price_paid": 1250000, > "date_proprietor_added": "2019-06-14", > "additional_proprietor": false, > "proprietors": [ > { > "name": "ACME TRADING LIMITED", > "company_number": "1234567", > "category": "Limited Company or Public Limited Company", > "address": ["10 High Street, London EC1A 1AA"] > } > ] > }, > { > "title_number": "MAN98765", > "tenure": "Leasehold", > "property_address": "Unit 4, Trafford Park, Manchester (M17 1AB)", > "district": "TRAFFORD", > "county": "GREATER MANCHESTER", > "region": "NORTH WEST", > "postcode": "M17 1AB", > "multiple_address": false, > "additional_proprietor": false, > "proprietors": [ > { > "name": "ACME TRADING LIMITED", > "company_number": "01234567", > "category": "Limited Company or Public Limited Company", > "address": ["10 High Street, London EC1A 1AA"] > }, > { > "name": "ACME HOLDINGS LIMITED", > "company_number": "07654321", > "category": "Limited Company or Public Limited Company", > "address": ["1 King Street, Manchester M2 4AA"] > } > ] > } > ] > }, > "created_at": "2026-11-09T09:41:15.822681Z", > "completed_at": "2026-11-09T09:41:15.901502Z" > } > ``` > [tab] Python > > ```python theme={null} > resp = requests.post( > f"{BASE}/api/v4/kyb/{applicant_id}/uk-land-registry-check", > headers=HEADERS, > json={"company_number": "01234567"}, > ) > result = resp.json() > print(result["status"], result["response_data"]["total_count"]) > ``` The same result can be fetched again later with `GET /api/v4/kyb/result/{request_id}`. ### Request body | Field | Type | Required | Description | | - | - | - | - | | `company_number` | string | Yes | Companies House company number: 8 letters or digits (e.g. `01234567`, `SC123456`).
