Business Census

This dataset contains information on companies registered in the UK. Fusion Data Science has been collecting the Companies House data into a database, since May 2012. This has enabled them to infer a history of company formations, dissolutions and other events that the monthly snapshot doesn’t capture. The database contains all 6+ million companies, and other corporate entities, which have existed since that time rather than the ~4 million contained in the Companies House data snapshots. More details can be found at: and See also the data specification at Companies House at and their FAQ at

These data are provided in a series of snapshots and in the original format. Each snapshot of the data records the companies present as of 31 March of a particular year in a flattened CSV file. The original data are organised in 12 tables, in which the company table is the central table and all other tables are linked to the company table via companyid.

This is the Version 9 release - May 2021. This replaces the Version 8 release from May 2021 and the Version 7 release from May 2020. Please note a new table is present for Version 9 - Company URI. Another table that first appeared in Version 8 - ONS Geography. For operational reasons, some of the files may be double-zipped (i.e. you need to unzip them twice).

The variables include: Company Number, Country Of Origin, Dissolution Date, Incorporation Date, Accounting Ref Day, Accounting Ref Month, Account Next Due Date, Account Last Made Update, Account Category, Careof, Po Box, Address Line 1, Address Line 2, Post Town, County, Country, Postcode, Company Category, Company Name, Num General Partners, Num Limited Partners, Company Status, Num Mortgage Charges, Num Mortgage Outstanding, Num Mortgage Part Satisfied, Num Mortgage Satisfied, SIC Code, SIC Description, Return Next Due Date, Return Last Made Update, Confirmation Next Due Date, Confirmation Last Made Update.
