As the Authority’s regulatory arm, Office for Statistics Regulation (OSR) is responsible for managing its casework function, undertaking monitoring to identify issues and investigating issues raised with the Authority.  We use our voice to stand up for statistics and to represent the public, reporting publicly where we have concerns and highlighting good practice.

Our interventions policy provides more details on our role in making public interventions on the use of statistics.

All issues considered are recorded in our issues log. Inclusion in the issues log does not necessarily mean that we share the concern, nor does it indicate a commitment to further action, although some of these matters will be followed up.

A high proportion of our current casework relates to COVID-19.  To see more about our work including statements we have made on these issues please visit our dedicated COVID-19 page.

We also produce an annual summary of our casework which provides details of the volume and types of cases we have looked at.

If you have any comments or feedback or would like highlight a concern with us please email Alternatively, you can write to us at: Office for Statistics Regulation, 1 Drummond Gate, London SW1V 2QQ


We are reviewing the format and amount of information we provide in the Casework issues log. This reflects our ambition to have clearer and more timely information available and the need for process changes as a result of the increased volume of casework we have received this year. Information for 2020/21 will be added once this review has been completed.
