Use this guide to turn official requirements into scope, evidence, owner, and review decisions. The Act applies to search services and services that let users post content or interact with each other, and it also includes exemptions and child-safety duties that teams should check before deciding they are in scope. This page explains whether a service is a user-to-user service or a search service under the UK Online Safety Act, what that means for compliance, and what evidence teams should keep when they decide how the Act applies. ## What should teams decide about User-to-user And Search Services under the UK Online Safety Act? 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-facing compliance requirement is triggered. The answer should be specific enough to show the service type, the relevant duty, and the evidence that supports the decision. 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. The Act applies to search services and services that allow users to post content online or interact with each other, while Schedule 1 lists exemptions such as email, SMS, and certain limited-functionality, education, childcare, and public-body services. - Define whether the service is a search service, a user-to-user service, or an exempt service under Schedule 1. - Record the product, feature, user group, and business reason that put the service in or out of scope. - Attach the source-linked rule, the owner, and the evidence field before approving the control. - Escalate uncertainty when the facts depend on exemptions, cross-border activity, child-access status, 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. For scope decisions, the evidence should also show why the service is or is not an exempt service and whether it has links to the UK. - Name one accountable owner and one reviewer for the User-to-user And Search Services 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 service is exempt, whether it has UK links, and whether children are likely to access it. - Check whether the service is an exempt email, SMS, one-to-one aural communication, limited-functionality, education, childcare, or public-body service. - 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. For this topic, the practical starting point is to classify the service correctly first, then map the duties that follow from that classification. - Create a short intake question that identifies whether the service is a user-to-user service, a search service, or an exempt service. - 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.
