Where this comes from.

Code descriptions are the ONS UK SIC 2007 structure. The 15,957 activities are the ONS alphabetical activity index, which is published as a separate spreadsheet and is the reason searching for barrister works here and not elsewhere. Company counts are the Companies House free register snapshot.

3 of the 731 codes have no activities listed, because they are administrative rather than a line of business: non-trading, dormant, and residents property management. ONS never indexed them, and we have not invented entries to fill the gap.
