Use this guide to turn official requirements into scope, evidence, owner, and review decisions. This guidance is practical, source-linked, and should be validated against current legal and policy requirements before implementation. This page helps you determine when UK Online Safety Act obligations apply, who owns each action, the required evidence, and the review path before escalation. In plain terms, a regulated service is generally a user-to-user service, a search service, or a service with links to the UK that publishes or displays provider pornographic content. ## What should teams decide about Regulated Service Scope under the UK Online Safety Act? Start by deciding whether the service is a regulated service: a user-to-user service, a search service, or a service with links to the UK that publishes or displays provider pornographic content. Then identify which illegal-content, children-safety, age-assurance, user-empowerment, transparency, complaints, risk-assessment, or provider duty that Ofcom can supervise or enforce is triggered. The useful answer should name the exact trigger, affected product or process, required action, owner, evidence, and escalation point. 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. - Define the exact Regulated Service Scope trigger and the business process it affects. - Record which role, product, system, customer group, or data flow is in scope. - Attach the source-linked rule, the owner, and the evidence field before approving the control. - Escalate uncertainty when the facts depend on thresholds, exemptions, cross-border activity, vulnerable users, or enforcement-sensitive wording.

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. - Name one accountable owner and one reviewer for the Regulated Service Scope workflow. - Keep source screenshots or source links, decision notes, implementation tickets, and approval records together. - Use dated evidence for deadlines, notices, risk assessments, contracts, user journeys, and regulator-facing records. - Review the evidence after product changes, new markets, new vendors, enforcement updates, or material changes in the source text.

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. - Check whether the rule changes for minors, consumers, business users, public-sector bodies, regulated sectors, high-risk services, or cross-border transfers. - Separate binding law, regulator guidance, consultation material, standards, and enforcement commentary in the evidence record. - Do not rely on a previous answer if the data categories, user interface, vendor role, or contractual flow changed. - Track unresolved assumptions in an open-questions section and route legal interpretation points for review.

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. - Create a short intake question that identifies the Regulated Service Scope scenario. - Map the answer to a required action, evidence field, owner, reviewer, and review date. - Link related artifact pages with descriptive anchors so users can move from scope to deadlines, controls, penalties, and templates. - Update the workflow when official source material changes or when internal evidence shows recurring exceptions.
