Best Auto Insurance in Connecticut

80 auto insurers ranked by formal complaint rates filed with state regulators. Lower complaints = better claims experience.

When drivers in Connecticut file a claim after a crash or theft, the experience varies widely from one company to the next. The 80 auto insurers ranked below are graded solely on formal complaints filed against them with state insurance regulators, not on price, advertising, or paid customer surveys. A higher grade means a company drew proportionally fewer complaints about claim delays, underpayments, and denials than its competitors.

Across the 80 graded companies, the breakdown is 23 A grades, 27 B grades, 24 C grades, and 6 D grades. Erie Insurance Exchange, HARTFORD FIRE INSURANCE COMPANY, and Cincinnati Casualty Company (The) post the strongest claims records in Connecticut, each drawing fewer complaints than the industry average. At the other end, INTEGON NATIONAL INSURANCE COMPANY and LM GENERAL INSURANCE COMPANY draw complaints at well above the typical rate. Compare every rated insurer below before you buy or switch, and weigh these grades alongside price and coverage rather than in place of them.
