Consumer law has been one of the most dynamic legal developments of the past half century. Although broad political support has driven the expansion of consumer protection, consensus on its underlying purposes has often proved more elusive. Tracing the evolution of consumer law in the United Kingdom, including the post-Brexit landscape, Consumer Protection examines the ideas and policy choices that have shaped the field and continue to influence its future. The book explores the case for a social welfare model of consumer protection. Rather than relying primarily on information disclosure and consumer choice, it argues that consumer law should secure reasonable expectations about the quality and safety of goods and services and the fair operation of markets. The analysis also addresses the major challenges confronting consumer law today, including digitalisation, environmental sustainability, and Brexit. Alongside these developments, it explores a persistent paradox: consumer law is intended to protect consumers, yet its rules are frequently complex and difficult to navigate. Combining historical perspective, theoretical analysis, and practical insights, the book considers how consumer regulation can be administered more effectively through access to justice, enforcement mechanisms, and the potential of class actions. The result is a clear and thought-provoking account of consumer law's foundations, achievements, and future direction.
