It has two run modes. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run. For examples already wired to this Actor's own input schema, see the [API](#api) section below. Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`). # README ## UK Companies House Search by SIC Code & Postcode Search and filter UK companies by **industry (SIC code)**, **postcode or town**, **incorporation date** and **status**, using public data from the Companies House register. Get a clean table of exactly the companies you are looking for, with company number, legal form, registered office address and SIC codes, ready for Excel, CSV, JSON or your CRM. **No API key, no code, no setup.** *Not affiliated with or endorsed by Companies House.* ### What can you use it for? - **Build lead lists by sector and area.** All active bakeries in London, software companies in Manchester, construction firms in a postcode area: one run, one spreadsheet. - **Spot new businesses early.** Schedule a daily run for companies incorporated since yesterday in your sector and reach them before your competitors do. - **Size a market.** Count how many companies are active per SIC code and region, and how many were founded each year. - **Track insolvencies in a sector.** List companies in liquidation or administration for risk monitoring, debt collection or acquisition scouting. - **Keep your data clean.** Check which companies in a sector have been dissolved, with the date. ### What you get Real output from a test run (SIC code 10710, London, active, incorporated since 2024): ```json [ { "schemaVersion": "company-registry/v1", "country": "GB", "registry": "Companies House", "registrationNumber": "15723526", "name": "NATURALIE LTD", "status": "active", "statusDetail": "Active", "legalForm": "Private limited company", "legalFormCode": "ltd", "incorporationDate": "2024-05-16", "dissolutionDate": null, "registeredAddress": "52 Hall Lane, London, NW4 4TN, England", "addressLine1": "52 Hall Lane", "addressLine2": null, "postalCode": "NW4 4TN", "city": "London", "region": null, "addressCountry": "England", "activityCodes": ["10390", "10710", "56103", "56210"], "activityDescriptions": [ "Other processing and preserving of fruit and vegetables", "Manufacture of bread; manufacture of fresh pastry goods and cakes", "Take-away food shops and mobile food stands", "Event catering activities" ], "activityScheme": "UK SIC 2007", "sourceUrl": "https://find-and-update.company-information.service.gov.uk/company/15723526", "retrievedAt": "2026-10-15T21:23:38.412Z" }, { "schemaVersion": "company-registry/v1", "country": "GB", "registry": "Companies House", "registrationNumber": "15755784", "name": "BANGALORE GROUP LTD", "status": "active", "statusDetail": "Active", "legalForm": "Private limited company", "legalFormCode": "ltd", "incorporationDate": "2024-06-02", "dissolutionDate": null, "registeredAddress": "Unit 1 819 Romford Road, London, E12 6EA, England", "addressLine1": "Unit 1 819 Romford Road", "addressLine2": null, "postalCode": "E12 6EA", "city": "London", "region": null, "addressCountry": "England", "activityCodes": ["10710", "47820", "56102", "56103"], "activityDescriptions": [ "Manufacture of bread; manufacture of fresh pastry goods and cakes", "Retail sale via stalls and markets of textiles, clothing and footwear", "Unlicensed restaurants and cafes", "Take-away food shops and mobile food stands" ], "activityScheme": "UK SIC 2007", "sourceUrl": "https://find-and-update.company-information.service.gov.uk/company/15755784", "retrievedAt": "2026-10-15T21:23:38.412Z" } ] ``` | Field | Description | | -------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- | | `registrationNumber` | Companies House company number | | `name` | Registered company name | | `status` | Simple status: `active`, `insolvent`, `dissolved` or `unknown` | | `statusDetail` | Status in Companies House wording, e.g. `Liquidation`, `In Administration` | | `legalForm`, `legalFormCode` | Legal form, e.g. `Private limited company` (`ltd`), `Limited liability partnership` (`llp`) | | `incorporationDate`, `dissolutionDate` | Dates as `YYYY-MM-DD` | | `registeredAddress` | Full registered office address on one line | | `addressLine1`, `addressLine2`, `postalCode`, `city`, `region`, `addressCountry` | The same address split into columns | | `activityCodes`, `activityDescriptions` | SIC codes with their official descriptions | | `sourceUrl` | The company's page on the public register | | `retrievedAt` | When the record was retrieved | | `schemaVersion`, `country`, `registry`, `activityScheme` | Fixed columns of the standard company-registry v1 layout | **Company data only.** No directors, shareholders or personal contact details: this Actor never requests them. The columns follow one standard layout (**company-registry v1**), designed to stay the same for other national company registers. Download the results as **Excel, CSV, JSON, XML or HTML**, or pull them in via the Apify API, Zapier, Make or Google Sheets. **Data source and licence.** The data comes from [Companies House](https://www.gov.uk/government/organisations/companies-house). Contains public sector information licensed under the [Open Government Licence v3.0](https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/). ### How much does it cost? You pay **per company**: **$2.50 per 1,000 companies** (pay-per-event). A list of 200 companies costs $0.50. - You are only charged for **valid companies** that land in your dataset. Searches without matches and failed requests are never charged. - Set a **maximum cost per run** in the run options. The run stops cleanly when that budget is reached. - Set **Maximum results** to cap the size of a run. ### Built to be reliable - **Straight from the register.** Data is read live through the Companies House public data API, not scraped from web pages. Website redesigns don't break it. - **Fast.** A filtered list of 1,000 companies takes seconds. - **Checks that the data is real.** Every record is validated (company number, name, dates, address). An empty or broken answer is retried and reported, never charged. - **Fair use built in.** Requests are paced well below the Companies House rate limit. If Companies House asks to slow down, the run pauses instead of pushing on. - **Honest results.** If nothing matches your filters, the run says so clearly and costs nothing. - **Clear error report.** Every run saves a `RUN_SUMMARY` with the number of companies and any failed requests per cause: proxy, rate limit, blocked, network or other. ### How to use it 1. Fill in one or more filters: **SIC codes**, **Postcode or town**, **Incorporated from/to**, **Company status** or **Company name contains**. 2. Set **Maximum results**. 3. Click **Start** and download your list when the run finishes (usually within seconds). Not sure which SIC code you need? Search the [official SIC code list](https://resources.companieshouse.gov.uk/sic/) of Companies House. ### Input | Field | Default | Description | | ------------------------------------------- | ------- | ---------------------------------------------------------------------------- | | Company name contains | empty | Only companies whose name contains this text | | SIC codes | empty | 5-digit UK SIC 2007 codes; a company matches if it has any of them | | Postcode or town | empty | Matches the registered office address, e.g. `London`, `Leeds` or `M1` | | Incorporated from / to | empty | Incorporation date range | | Company status | all | e.g. Active, Dissolved, Liquidation, In administration | | Maximum results | 100 | Stop after this many companies (max 10,000 per search) | | Your own Companies House API key (optional) | empty | Not needed. Heavy users can add their own free key for a separate rate limit | At least one filter is required. Example input: ```json { "sicCodes": ["10710"], "location": "London", "incorporatedFrom": "2024-01-01", "status": ["active"], "maxResults": 50 } ``` ### FAQ **Do I need a Companies House API key?** No. The Actor works out of the box. If you run very large or very frequent jobs, you can add your own free key from the [Companies House developer hub](https://developer.company-information.service.gov.uk/) to get your own rate limit. **How many companies can one search return?** Up to 10,000. This Actor is built for targeted searches: combine SIC codes, a town or postcode, dates and status to get exactly the companies you need. **How fresh is the data?** It is read live from the register at the moment of your run. **Why are there no directors or e-mail addresses?** By design: this Actor only collects company data, no personal data. **Is this legal?** The Companies House register is public, and this Actor reads it through the Companies House public data API. Contains public sector information licensed under the [Open Government Licence v3.0](https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/). You remain responsible for how you use the data, for example under UK GDPR and direct marketing rules. **Is this an official Companies House service?** No. Not affiliated with or endorsed by Companies House. **A run returned fewer companies than expected.** Open `RUN_SUMMARY` in the run's storage: it shows how many requests failed and why. **Something is broken or missing?** Open an issue on the Issues tab. We usually reply within a few working days. # Actor input Schema ## `query` (type: `string`): Only companies whose name contains this text, e.g. bakery.
