🔄 Loi Hamon is a French consumer protection law enacted in 2014 (Loi n° 2014-344 du 17 mars 2014) that grants policyholders the right to cancel certain insurance policies at any time after the first twelve months of coverage, without penalty and with only one month's notice. Named after Benoît Hamon, the Minister of Consumer Affairs who championed it, the law applies to compulsory or quasi-compulsory personal lines products — principally motor insurance, home insurance, and mortgage insurance (assurance emprunteur, for the first year) — and fundamentally altered the competitive dynamics of the French retail insurance market.

⚙️ Before Loi Hamon, French policyholders were generally bound by annual contract cycles and could only cancel during a narrow window before the automatic renewal date, as regulated by the Loi Châtel. The new framework eliminates this timing constraint after the initial year: a policyholder simply notifies the new insurer, which handles the cancellation formalities with the outgoing carrier on the customer's behalf. For mortgage insurance, Loi Hamon provided a twelve-month free-look substitution period from the date of loan signing — a right later extended to an annual right by the Loi Bourquin. The law places the administrative burden of the switch on the incoming insurer, streamlining the process for consumers and reducing the friction that previously discouraged switching.

📈 The market impact has been significant. Loi Hamon catalyzed the growth of insurance comparison platforms and direct-to-consumer insurtech models in France, as the ease of switching created genuine customer mobility for the first time in mass-market personal lines. Incumbent insurers responded by investing in retention strategies, improving pricing transparency, and upgrading digital servicing capabilities to reduce churn. The law also contributed to a broader downward pressure on personal lines premiums, particularly in motor insurance, by intensifying price competition. For the global insurance industry, Loi Hamon represents one of the most consumer-friendly cancellation regimes in any developed market and is frequently studied as a reference model for regulators considering similar liberalization of policy portability.
