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. Age Assurance under the UK Online Safety Act is about checking or estimating a user's age so services can keep children away from content the Act requires them to block, and apply the right safety measures for the service's users. ## Age assurance basics under the UK Online Safety Act Age assurance is the process of checking or estimating a user's age. The UK Government says services should use age estimation and age verification, and that the Act requires a wide range of services to deploy highly effective age assurance to protect children from extremely harmful content, including pornography and content that encourages, promotes or provides instructions for suicide, self-harm or eating disorders. For visitors, the practical question is simple: if children are likely to use the service, does the service need age assurance, and if so, what method will be used, who owns it, and how will the team show it is working? - Check whether the service is in scope and whether children are likely to access it. - Choose an age assurance method that fits the risk and the user experience. - Keep a record of the rule, the owner, the evidence, and the review date. - Escalate where the service, audience, or risk profile changes.

Ownership should sit with the team that can change the product, policy, or safety controls, with legal and trust-safety review where needed. Evidence should show the service scope, the age assurance method, the decision, the owner, and the review trail. - Name one accountable owner and one reviewer for the age assurance workflow. - Keep source links, decision notes, implementation tickets, and approval records together. - Use dated evidence for notices, risk assessments, user journeys, and regulator-facing records. - Review the evidence after product changes, new markets, new vendors, or material changes in the source text.

Use this section before launching a new feature, changing a recommender, changing moderation rules, or updating an age assurance flow. - Check whether the rule changes for different service types, audiences, or access paths. - 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 a workflow that captures service scope, user groups, risk assessment, child-access status, the age assurance method, the owner, and the escalation path. The output should be a short service memo, a decision record, and the evidence needed to show the control was reviewed and approved. - Create a short intake question that identifies the age assurance 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.
