UK Online Safety Act penalties and fines

Ofcom is responsible for enforcing the Online Safety Act, and its maximum penalty for regulated service providers is the greater of GBP18 million and 10% of qualifying worldwide revenue. Start by deciding whether the service is in scope and which illegal-content, children-safety, age-assurance, user-empowerment, transparency, complaints, risk-assessment, or Ofcom enforcement duty is triggered.

Keep the Online Safety Act source, service-scope decision, user-to-user/search feature map, risk assessment, code-of-practice mapping, age-assurance evidence, and Ofcom-facing record together.

Ownership should sit with the team that can change service design, moderation, recommender systems, age assurance, reporting, complaints, terms, or transparency data, with legal and trust-safety review.

Evidence should show service categorisation, illegal-content risk assessment, children access assessment, children risk assessment, mitigation controls, age-assurance decisions, terms/complaints records, and Ofcom reporting readiness.

Most Online Safety Act mistakes happen at the boundary between user-to-user, search, pornography, category, child-access, illegal-content, and transparency duties.

Use this section before launching a user feature, recommender change, moderation change, age-assurance flow, complaint process, or transparency-reporting process.

Use an Online Safety Act workflow that captures service scope, user groups, risk assessment, code mapping, child-access status, mitigation owner, evidence, and Ofcom escalation path.

The output should be a service-scope memo, risk assessment, children access assessment, mitigation plan, age-assurance decision, complaint workflow, or transparency-report evidence pack.
