The ICO as announced that it will publish details of reprimands as well as fines, and in fact it has already started.
Looking at the reprimands online at https://ico.org.uk/action-weve-taken/reprimands/ it is disappointing that such a high proportion seem to be government departments and local authorities, but perhaps this is in the spirit of not being as quick to fine public authorities.
And it does make interesting reading, to see how the ICO enforcement team are thinking.
