UK Land Registry Check

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.

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.

Curl
Python

export API_KEY=<YOUR_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:

{
  "id": "01827ed4-c928-7a3c-9a30-7ab7cc169d11"
}

import requests

API_KEY = "<YOUR_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 first. Unlike the other KYB checks, this one is synchronous: the response already contains the result, so there is nothing to poll.

Curl
Python

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"}'
