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

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.

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 [email protected].
