UK Law Commission Proposes Landmark Overhaul of Product Liability Law to Include Software and AI Systems

LONDON — In a move that promises to fundamentally reshape the legal landscape for modern commerce, the UK Law Commission has officially launched a sweeping consultation on major reforms to update product liability law. Announced on October 8, the proposals seek to drag a nearly 40-year-old legislative framework into the digital age by formally expanding the definition of a "product" to encompass standalone software, sophisticated artificial intelligence (AI) systems, and online platforms.

The initiative aims to address a glaring vulnerability in the contemporary legal system: while smartphones, smart home devices, generative AI models, and cloud-based applications have become foundational to daily life, the laws governing compensation for defective items remain anchored in an era dominated by physical manufacturing. By tackling this legislative gap, the Law Commission hopes to balance robust consumer protection with vital regulatory clarity for tech developers and commercial enterprises.

Main Facts

The core objective of the consultation is to modernize the UK’s product liability regime, which currently relies on standards established nearly four decades ago. Under the current framework, consumer redress mechanisms—such as the right to seek compensation for injuries or property damage caused by a dangerous item—are largely restricted to tangible, physical goods.

The Law Commission’s new white paper outlines several pivotal changes designed to rectify this mismatch:

• Redefining "Products": The scope of liability will be broadened to include intangible digital assets, specifically standalone software, AI algorithms, and online distribution platforms.
• Enhanced Consumer Redress: The proposals aim to provide absolute clarity regarding when individuals harmed by software failures or algorithmic malfunctions are legally entitled to compensation.
• Business Clarity: Alongside consumer rights, the framework seeks to establish predictability for software developers, AI startups, and multinational technology giants operating within the UK market.
• Open Consultation Timeline: The call for evidence is active immediately, with the formal consultation window closing on Thursday, January 14, 2027. Following analysis of the feedback, final recommendations are anticipated in late 2027.

Chronology of the Legislative Gap

To understand the magnitude of the Law Commission’s current endeavor, it is necessary to examine how rapidly technology has outpaced legal evolution over the last half-century.

• 1985–1987 (The Analog Era): The foundation of modern product liability law in the UK and broader Europe was laid with the European Product Liability Directive (85/374/EEC), which was transposed into UK law via the Consumer Protection Act 1987. At this time, commerce was centered on physical manufacturing defects—faulty automotive brakes, exploding television sets, or toxic toys. Software was in its infancy, largely proprietary, bundled strictly with hardware, and rarely autonomous.
• The 2000s–2010s (The Digital Transition): As personal computing gave way to smartphones, mobile applications, and cloud computing, legal scholars began noting cracks in the 1987 Act. A consumer harmed by a malfunctioning physical medical device had clear paths to legal recourse; however, a consumer harmed by a corrupted medical diagnostic app or a malfunctioning GPS navigation system on a smartphone often found themselves in a legal gray area, struggling to prove whether software constituted "goods" or "services."
• The AI Revolution (Present Day): With the rapid proliferation of machine learning, generative AI, and autonomous decision-making systems, the inadequacy of the physical-only definition became unsustainable. AI systems can now autonomously pilot vehicles, diagnose illnesses, manage financial portfolios, and control critical infrastructure, making the absence of clear software liability a significant risk to public safety.
• October 8, 2026 (The Current Turning Point): The Law Commission officially launches its consultation paper, marking the first formal step toward legislative modernization for the digital economy.

Supporting Data and the Digital Transformation

The urgency of the Law Commission’s review is underscored by massive shifts in the global and domestic economy. Over the past decade, the UK has positioned itself as a leading global hub for artificial intelligence and software engineering. According to recent industry metrics, the UK tech sector is valued at over $1 trillion, employing millions of people and driving substantial economic growth.

However, this economic dominance has introduced novel risks:

• The Shift to Intangibles: In 1987, the vast majority of consumer spending was directed toward physical goods. Today, a significant percentage of consumer expenditure goes toward software-as-a-service (SaaS) subscriptions, digital apps, in-game purchases, and algorithmic tools.
• Autonomous Decision-Making: Unlike traditional products that remain static after leaving the factory floor, modern AI systems are dynamic. They learn, adapt, and update over time via continuous machine learning loops. This creates unique challenges for establishing fault—distinguishing between a defect introduced during initial coding versus an error caused by subsequent autonomous adaptation.
• The Cross-Border Challenge: Digital products are borderless. A bug in an AI model developed in Silicon Valley or Shenzhen can instantly impact millions of UK consumers. Integrating these systems into a localized product liability framework provides a vital domestic shield for British citizens.

Official Responses and Stakeholder Perspectives

The Law Commission’s proposals have already generated significant discussion among legal experts, consumer advocates, and industry leaders.

Professor Solène Rowan, Commissioner for Commercial and Common Law, emphasized the necessity of bridging the gap between outdated laws and modern realities. In a statement accompanying the launch, Professor Rowan noted:

"The law governing defective products was introduced long before smartphones, social media and artificial intelligence became part of everyday life. As technology evolves, the law must evolve with it. Our proposals are designed to ensure that people harmed by defective products can obtain compensation, while providing greater clarity and certainty for businesses developing the products and technologies of the future."

Consumer Advocates

Consumer rights groups have broadly welcomed the consultation, arguing that victims of algorithmic errors or software failures have historically faced insurmountable procedural hurdles. Without a clear statutory framework, consumers injured or financially damaged by software bugs often had to rely on complex contract law or negligence claims, which require proving a direct breach of a duty of care—a notoriously difficult task when dealing with black-box AI models.

Industry and Legal Professionals

Technology companies and corporate defense lawyers have expressed a mixed, albeit constructive, response. While businesses generally prefer light-touch regulation to foster innovation, many tech firms have privately acknowledged that legal ambiguity is detrimental to long-term investment. Clear liability boundaries allow companies to properly price risk, secure appropriate liability insurance, and design safer products from the outset.

However, tech sector stakeholders are expected to closely scrutinize how the Law Commission defines "defects" in the context of autonomous systems, specifically concerning how far a manufacturer’s liability extends when an AI system behaves in ways unforeseen by its original creators.

Broader Implications for the Legal and Tech Sectors

If the Law Commission’s recommendations are ultimately enacted into law following the conclusion of the consultation process, the ramifications will be profound across multiple sectors:

1. Insurance and Risk Management

The insurance industry will experience a major transformation. Insurers will need to develop entirely new categories of product liability coverage specifically tailored for software houses, AI developers, and platform operators. Underwriting will likely shift from evaluating physical manufacturing safety protocols to auditing code quality, algorithmic training data, cybersecurity measures, and automated update management.

2. Compliance and Quality Assurance

Software development life cycles (SDLC) will increasingly incorporate rigorous legal compliance checks. Developers will have to implement robust traceability and documentation practices to prove that their software or AI systems met the state-of-the-art safety standards at the time of release, potentially utilizing statutory defenses such as the "development risks defense" (where a manufacturer is not held liable if the state of scientific and technical knowledge at the time was not advanced enough to discover the defect).

3. Judicial Precedent and Litigation

The courts will likely see a new wave of litigation testing the boundaries of software-induced harm. Judges will be tasked with interpreting how traditional legal concepts—such as causation, foreseeability, and merchantable quality—apply to intangible code and evolving neural networks.

How to Participate in the Consultation

The Law Commission has stressed that shaping a future-proof legal framework requires broad public and professional engagement. Input is actively sought from:

• Consumers and Consumer Advocacy Organizations
• Software Developers, AI Startups, and Tech Giants
• Manufacturers utilizing embedded software or smart technologies
• Legal Practitioners, Academics, and Regulatory Experts

The consultation window remains open until Thursday, January 14, 2027.

Interested parties can submit their feedback via the official online response form hosted on the Law Commission Product Liability Project Page. Alternatively, written responses can be directed via email to the project team at [email protected].

Following the closure of the consultation, the Commission will review all submissions, draft comprehensive policy proposals, and publish its final report and draft legislation in late 2027.
