UK Companies House API Scraper — PSC, iXBRL Accounts, Filings

UK Companies House API Scraper turns Companies House records into clean JSON, CSV, Excel, NDJSON, or Markdown. Use it to scrape UK company profiles, PSC ownership, officers, filings, charges, insolvency cases, Gazette notices, and accounts data from official UK sources.

This Actor works like a simple Companies House API on Apify. Pick a mode, enter a crn, company name, officer ID, search query, charge ID, or PSC ID, then start the run. Results are saved to an Apify dataset or to a file in the key-value store.

Tips for best results

• Use a CRN when you have one. It is more precise than a company name.
• Use maxResults on search and list modes to control run size.
• Use dateFrom and dateTo for filing and stream modes.
• Use outputFormat: "md" when you want text for ChatGPT, Claude, or a report.
• Start with company_profile before running deeper checks such as PSCs, charges, officers, or accounts.

Use from Python

from apify_client import ApifyClient

client = ApifyClient("<APIFY_TOKEN>")
run = client.actor("dominvo/uk-companies-house-api-ai-scraper").call(run_input={
    "mode": "psc_list",
    "crn": "09446231",
    "maxResults": 50,
})

for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(row["payload"])
