Companies House Scraper & API: UK Company Lists by SIC Code

Search all ~5.7 million companies on the UK register using the official Companies House bulk data (Basic Company Data, refreshed monthly, Open Government Licence v3.0). Filter by name, SIC code, postcode, town, status, company type and incorporation date, and get one clean row per company with its number, registered address, SIC codes and key dates.

• Who it's for: B2B lead generation (e.g. new IT companies in London this month), CRM enrichment, market sizing and KYB checks.
• Source: the official free Companies House bulk file. No API key, no 600-requests-per-5-minutes limit, no scraping.
• Freshness: monthly snapshot from Companies House; directors and filings are not included.
• Output: JSON, CSV or Excel; pay per company returned (see the Pricing tab).

Many new companies share a formation-agent address (here 128 City Road, EC1V 2NX), so a postcode filter is not proof of a real office there.

FAQ

How fresh is the Companies House data?

It is the official monthly Basic Company Data snapshot, so a company registered yesterday may not appear until the next release.

Does it include directors or PSCs?

No. Officers and persons with significant control are not in this product, so the output has no personal data beyond what appears in a registered company name.

Do I need a Companies House API key?

No. The Actor downloads the free bulk files, so the 600-requests-per-5-minutes API limit does not apply.

How much does it cost?

$2 per 1,000 companies plus $0.01 per run.

Are there limits I should know about?

Yes. Results are only as complete and current as the official source. If a source is down, the run logs the error instead of returning made-up data. Report problems in the Issues tab.

Use it from code, AI agents and automations

The same input as the form above works everywhere. Results are the run's dataset (JSON, CSV, Excel). You need an Apify API token (Console → Settings → API & Integrations).

Python (pip install apify-client)

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("stazis/companies-house-api").call(run_input={
  "sicCodes": [
    "62012"
  ],
  "postcodePrefixes": [
    "EC1"
  ],
  "statuses": [
    "Active"
  ],
  "incorporatedFrom": "2026-09-01",
  "maxItems": 20
})
for item in client.dataset(run.default_dataset_id).iterate_items():  # apify-client < 3: run["defaultDatasetId"]
    print(item)

JavaScript / TypeScript (npm i apify-client)

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor('stazis/companies-house-api').call({
  "sicCodes": [
    "62012"
  ],
  "postcodePrefixes": [
    "EC1"
  ],
  "statuses": [
    "Active"
  ],
  "incorporatedFrom": "2026-09-01",
  "maxItems": 20
});
const { items } = await client.dataset(run.defaultDatasetId).listItems();

HTTP, one call (waits for the run, up to 5 minutes, and returns the items)

curl -X POST "https://api.apify.com/v2/acts/stazis~companies-house-api/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" -H "Content-Type: application/json" \
  -d '{"sicCodes": ["62012"], "postcodePrefixes": ["EC1"], "statuses": ["Active"], "incorporatedFrom": "2026-09-01", "maxItems": 20}'

AI agents (MCP). This Actor runs with limited permissions, so AI agents can use it through the hosted Apify MCP server (Claude, Cursor, VS Code, Codex and other MCP clients). Add this to your MCP client config and sign in with Apify on first use:

{ "mcpServers": { "companies-house-api": { "url": "https://mcp.apify.com?tools=stazis/companies-house-api" } } }

Agents without an Apify account can pay per run in USDC through agi.apify.com (x402). Pricing is pay-per-event, so an agent pays only for the results it gets.

LangChain (pip install langchain-apify, set APIFY_TOKEN): from langchain_apify import ApifyActorsTool and tool = ApifyActorsTool("stazis/companies-house-api") gives your agent this Actor as a tool.

No-code and scheduling: use the Apify app in Make, n8n or Zapier ("Run an Actor", then pick stazis/companies-house-api), or create a Schedule in Apify Console to run it daily and send results to a webhook, Slack or Google Drive through Apify integrations.
