Company Register 100% open

Great Britain

What data is expected?

List of registered (limited liability) companies. The submissions in this data category do not need to include detailed financial data such as balance sheet, etc. Open data from company registers may be used for many ends: e.g. enabling customers and businesses to see with whom they deal, or to see where a company has registered offices. This definition draws on the work of OpenCorporates.

  • Name of company
  • Company address
  • Unique identifier of the company
  • Register available for entire country

findable_steps No steps. I am a user of the data and have been aware of its location since the original release in 2012. However the dataset is easily found via Google using search terms such as: company data britain
licence_url https://www.whatdotheyknow.com/request/free_company_dat Companies House maintains the data in a public register under statute. CH does not claim any intellectual property rights in the Free Company Data Product and therefore does not apply the Open Government Licence to the data. I have provided a link to correspondence from 2014 in which CH explains its position on re-use of the data.
Collected by government Yes
usability 2 No data are usable without human effort. The data are formatted to be both human and machine-readable. However the dataset is too large to be easily managed in a spreadsheet programme so the user will need some basic knowledge of database software to manipulate the data.

Your submission is valid. Thank you very much for contributing to the Global Open Data Index. All 4 required characteristics were found online: UK's companies' names, addresses and unique identifiers are included in machine-readable .CSV files that are publicly available and can be downloaded for free in bulk (in 5 parts) from the Companies House website. The website is easily found through a Google search for "uk chamber of commerce" which leads to a page directing to Companies House (http://www.britishchambers.org.uk/business/business-faqs/where-can-i-go-to-get-a-list-of-registered-companies-in-the-uk.html). People have complained about corrupted data files and outdated data on the data.gov.uk page (https://data.gov.uk/dataset/basic-company-data) so downloading them directly from the Companies House website (http://download.companieshouse.gov.uk/en_output.html) is preferable. Data were lastly updated on 03/02/2017 (today's date is 07/02/2017). Although machine readable, some human effort is required to manipulate the data as the dataset is too large.
