Complaints Commissioner

Find out about the role of the Complaints Commissioner and how to get in touch.

We have set up arrangements for investigating complaints made against us.

As part of these arrangements, a Complaints Commissioner is appointed, whose role is to investigate certain complaints and report to the complainant and us. The report may include recommendations to us, for example that we make an ex-gratia payment to the complainant. We decide whether to make any such payments.

Final reports

The Complaints Commissioner publishes their response to each complaint they deal with – read them at Complaints Commissioner's final reports.
