I think I'll make a FOI request to the IC:

Its Online Publications Request at https://www.informationcommissioner.gov.uk/eventual.aspx?id=7127 gives the following:

You may also request these publications and leaflets by calling 08453 091 091 (calls charged at national rate).

The Employment Practices code and the Quick Guide to the Employment Practices code are available by ringing 08453 091 091.

Its publication Freedom of Information - Your right to know - How to complain gives these numbers (without pricing info) for obtaining publications:

Publications Line
t: 08453 091 091
f: 0870 600 81 01

I hope they answer the FOI as they should because it certainly would be a conflict of interest having to ask IC to investigate themselves.  lol.  ;D
