Overview

The right UK OSA checklist is not a list of policy topics. It is a control register that proves the service has been scoped correctly, assessed on time, updated after changes, and supported by live moderation, child safety, and regulator-response processes.

Section 2

Risk and control checklist

Verify that the illegal content risk assessment, child access assessment, and children risk assessment were completed on time where required and that they now drive actual controls.

Look for evidence of tuning, testing, and exception handling rather than only first-version signoff.

  • Illegal content risk assessment completed and refreshed
  • Children access and children risk assessments completed where relevant
  • Moderation, age assurance, complaints, and escalation controls tested
  • Terms enforcement QA and user-redress data retained
Section 3

Regulator readiness checklist

Ofcom readiness means the service can answer information requests quickly, explain its risk logic, and produce current evidence for the controls it claims to run.

A checklist item is not complete if the artifact exists but no one can locate or explain it.

  • Information notice response owner named
  • Senior management escalation path documented
  • Transparency and category reporting data sources identified
  • Evidence folder tested with a mock regulator request
