Free Accounts Data Product

Until further notice the Monthly Accounts Data File has been temporarily suspended. Please download the data from the daily accounts files. We apologise for any inconvenience this has caused.

Previous Year's Monthly Files

What is it?

The Accounts Data Product is a free downloadable ZIP file, which contains the individual data files (instance documents) of company accounts filed electronically.

Accounts data for the previous year can be downloaded from the monthly files provided here, whilst the most recent accounts data is available from the daily files.

The individual data files within the ZIP file will be in one of two formats, either:

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

Each data file is provided free of charge and is not supported. Due to its size, each file can take several minutes to download.

When will each file be updated?

A new monthly file will be added within 5 working days of the previous month end.

How long is each file available to download?

Each monthly file will only be available to download for 12 months, after which it will be replaced by the corresponding file for the following year.

What information is in the monthly file name?

The monthly ZIP file name identifies the month and year the accounts data relates to.

The individual filenames within will identify the company number (e.g. 01234567) and balance sheet date (e.g. 31/12/2012). The file type indicates if it is iXBRL (html) or XBRL (xml).
e.g. Prod224_0009_01234567_20121231

Prod224_0009 are internal run processes.

Additional Information

Data is only available for electronically filed accounts, which currently stands at about 75% of the 2.2 million accounts we expect to be filed each year.

You can view the data using Notepad, or a similar text based program. A rendered image of the accounts can be viewed when opened via a web browser. To view the data within your browser, use right-click and "View Source".

Both iXBRL and XBRL are difficult to manipulate without specialised software. Below are examples of the data format.

The taxonomies referenced by the accounts data in the monthly files may have changed over the year. For more information on referenced taxonomies,validation and formatting, please read our Free Accounts Data Product FAQs.
