About this book:

This book offers a clear, step‑by‑step guide to the Online Safety Act 2023, translating the legislation’s dense legal language into plain English that anyone working with UK‑facing online services can understand. You will learn the Act’s core purpose, its scope across user‑to‑user platforms, search engines, and combined services, and how it introduces a new duty of care that requires providers to proactively assess and mitigate risks of harm.

Each chapter walks you through the key definitions that shape compliance—such as regulated user‑to‑user service, illegal content, content harmful to children, and priority offences—so you can correctly identify which parts of your service fall under the Act’s requirements. Practical examples illustrate how to conduct illegal‑content and children’s risk assessments, implement proportionate safety measures, and maintain the transparency reports and complaints procedures that OFCOM expects.

You will discover the specific obligations that apply to different service categories, including the enhanced duties for Category 1 and Category 2A platforms, the requirements for age verification or age estimation to protect children from pornographic content, and the rules around fraudulent advertising, user identity verification, and reporting child sexual exploitation and abuse to the National Crime Agency. The book also explains OFCOM’s expanded powers, from issuing information notices and codes of practice to enforcing penalties, service restriction orders, and senior manager liability.

Technical professionals will gain insight into how the Act influences service design, algorithmic decisions, content moderation systems, and the use of proactive technology, while business managers will learn how to align terms of service, internal policies, and financial planning with the Act’s compliance demands to avoid costly fines and reputational damage. Throughout, the book emphasizes a balanced approach that respects freedom of expression and privacy while promoting online safety.

By the end of this guide, you will have a solid grasp of your legal obligations, a roadmap for implementing necessary changes, and the confidence to navigate the evolving regulatory landscape. Whether you are a developer, product manager, compliance officer, or simply curious about how the internet is regulated in the UK, this book equips you with the knowledge and practical tools needed to comply with the Online Safety Act 2023 and contribute to a safer online environment.
