Which regulation requires insurers to cancel add-on policies when the main policy is canceled mid-term?

The correct answer is that the regulation requiring insurers to cancel add-on policies when the main policy is canceled mid-term is outlined in the Consumer Rights Act 2015. This Act emphasizes consumer protection and ensures that consumers are treated fairly when they enter into contracts, including insurance policies. Under this Act, if a primary insurance policy is canceled, the associated add-on policies must also be terminated to prevent consumers from being unfairly charged for services they no longer need or for which they were not benefitting.

The Consumer Credit Act 1974 primarily deals with credit agreements and consumer credit protections, which does not directly relate to insurance policy cancellations. The General Data Protection Regulation (GDPR) focuses on data privacy and the handling of personal data, which is not relevant to the cancellation of insurance policies. The Insurance Act 2015 governs the terms and conditions of insurance contracts rather than specifically addressing the cancellation process related to add-on policies. Thus, the Consumer Rights Act 2015 is the most appropriate regulation in this context.
