Which piece of legislation was enacted to enhance consumer protection on October 1, 2015?

The Consumer Rights Act 2015 is the piece of legislation that was specifically enacted to enhance consumer protection starting on October 1, 2015. This Act consolidated and updated previous laws regarding consumer rights, focusing on goods, services, and digital content, ensuring that consumers receive fair treatment and clear information about their purchases.

The legislation also included provisions for addressing issues such as unfair terms in contracts, allowing consumers to seek redress if services do not meet the specified standards or descriptions. By strengthening the rights of consumers, the Act aimed to create a fairer marketplace and promote consumer confidence.

The other options represent important legislation as well, but they serve different specific purposes. For instance, the Motor Insurance Directive relates specifically to motor insurance regulation within the EU, the Insurance Act 2015 primarily concerns the insurance industry's operations and the duties of both insurers and insureds, and the Fair Trading Act 2015, while promoting fair trading practices, does not focus exclusively on consumer rights in the same comprehensive manner as the Consumer Rights Act.
