Historic summaries

Reporting summaries 2013-20

These summaries prior to January 2021 were prepared on a different basis. We have reviewed and released summaries of notifications between 1 October 2018 to 31 December 2020 and released these as part of the open data release. The original summaries are below. No further releases of notifications prior to 1 October 2018 will be made due to changes in the way these were recorded.
