Companies House data products

How to access public data from the Companies House register using our data products and DVD directory.

Company data product

The company data product is a free monthly snapshot of information for live companies on the public register. This includes:

  • basic information including company type and registered office address
  • the nature of business or standard industrial classification (SIC)
  • company status, such as ‘live’ or ‘dissolved’
  • date of last accounts or confirmation statement filed
  • date of next accounts or confirmation statement due
  • previous company names
  • current officer details

Access the free company data to get bulk downloads of UK company data.

The bulk snapshot is split into a number of downloadable ZIP files which contain data in comma separated values (CSV) format.

The snapshot contents are compiled up to the end of the previous month and made available for download within 5 working days of the previous month end.

Find more information about the data returned in our Uniform Resource Identifiers (URI) Customer Guide (PDF, 370KB, 9 pages)

Accounts data product

The accounts data product is a free downloadable ZIP file, which contains the individual data files (instance documents) of company accounts filed electronically at Companies House.

The data is provided in eXtensible Business Reporting Language (XBRL) format.

Access the daily accounts data files or the monthly accounts data files for the last year.

The individual files within the ZIP file will be in one of the following formats:

  • inline XBRL format (.html file extension)
  • XBRL format (.xml file extension)

A new daily file is added each morning over a 5-day period (Tuesday to Saturday). Each file contains the accounts data registered on the previous day.

A new monthly file is added within 5 days of the end of the previous month.

Data is only available for electronically filed accounts, which currently stands at about 60% of the 2.2 million accounts filed at Companies House each year.

People with significant control (PSC) data product

The PSC data product provides a snapshot as a single data file in JSON format and contains a full list of PSCs provided to Companies House.

Access our PSC data product.

Uniform resource identifiers (URI)

Our free URI service gives access to basic company details using a simple uniform resource identifier (URI) for each company on our register.

The URI is a unique web address for each company. Simply use the company number within the URI structure: http://data.companieshouse.gov.uk/doc/company/{companynumber}

Example Company number 02050399 would be represented as: http://data.companieshouse.gov.uk/doc/company/02050399

Use the URI address with your internet browser and it will display the company data as a HTML page. You can also return other data formats including RDF, JSON, XML, CSV and YAML.

The URI can be embedded as a link on your own website or the data can be used in your own software.

XML gateway search service

Our XML gateway offers access to Companies House data and documents as a computer to computer search service.

Data and documents are requested and delivered using XML (eXtensible Markup Language). This will allow users of the service to search company records from within their own software.

Standard XML data schemas must be used as defined in the interface specification which can be found on our dedicated XML gateway output page.

Users must carry out a test to confirm they can request and receive data before an XML output account can be opened.

There’s a monthly subscription fee of £4.70, plus additional charges for data or documents requested. Users get 15% off their total monthly invoice value. Basic company information is available for free.

If you’d like to know more about development or testing, you can contact xml@companieshouse.gov.uk.

DVD directory

Our DVD directory contains basic company details on all live companies registered in the UK, along with companies that have become dissolved in the last month.

The DVD has a built in search facility that allows up to 6 combinations of searches on:

  • company name
  • company number
  • registered office address lines
  • postcode
  • date of incorporation or range of dates
  • SIC code(s) or description
  • company type
  • company status
  • accounts type

The directory is produced monthly and a one off copy costs £30, or a year’s subscription for £300. To order a copy:

The DVD directory does not show details of annual turnover, telephone numbers or directors’ details.

The data cannot be exported, but we do provide a one off version of the directory with exportable files. This costs £1,000. The maximum number of results we can export at one time is 30,000.

The data on each DVD is available for 6 months from the date of purchase. After this, it locks and you will not be to access the data.

You must set Internet Explorer as the default browser to use this product. It’s not compatible with Apple Mac computers.
