To find top-rated insurance companies, check four independent sources before you buy: J.D. Power studies for customer satisfaction, the NAIC complaint index for how often customers file complaints relative to company size, AM Best ratings for financial strength, and your state insurance department's complaint data and licensing records. Then compare quotes for identical coverage.
Every insurance ad promises great service. The real test comes when you file a claim after a car accident or a burst pipe. At that moment, how a company treats its customers matters far more than any slogan.
The good news is that you do not have to take an insurer’s word for it. Several independent sources let you check customer satisfaction, complaint history and financial health before you sign up. Here is how to use them.
How to Identify Top-Rated Insurance Companies
No single rating tells the whole story. A company can be financially rock-solid but frustrating to deal with, or friendly on the phone but slow to pay claims. That is why it helps to look at several types of data together:
- Customer satisfaction surveys, such as J.D. Power studies
- Complaint data, such as the NAIC complaint index and state records
- Financial strength ratings, such as AM Best
- Your own experience with quotes, service and claims questions
Ratings change from year to year and often differ by region and product, so always check the most recent data for the type of insurance you are buying.
J.D. Power Studies: What Customers Say
J.D. Power publishes annual studies that survey policyholders about their experiences with insurers. There are separate studies for different products and touchpoints, for example auto insurance shopping and satisfaction, auto claims, home insurance, and health plans. Auto studies are often broken out by region, so the results in the Southeast can look different from those in California.
How to use it: look at the study that matches what you are buying and where you live. Pay special attention to claims satisfaction studies, since the claims experience is when service matters most.
Keep in mind: survey results reflect customer perceptions during a specific period. They are useful for comparing companies, but they do not measure financial strength or guarantee how your own claim will go.
The NAIC Complaint Index: How Often People Complain
The National Association of Insurance Commissioners (NAIC) collects data on complaints that consumers file with state insurance departments. Its free Consumer Insurance Search tool lets you look up a company and see its complaint history.
Understanding the complaint index
The complaint index compares a company’s share of complaints to its share of the market for a given line of insurance. A national baseline is set at 1.00:
- Below 1.00 means the company received fewer complaints than expected for its size.
- Above 1.00 means it received more complaints than expected.
This adjustment matters. A very large insurer will naturally receive more total complaints than a small one simply because it has more customers. The index levels the playing field.
Tip: look up the exact legal company name that will issue your policy. Big insurance groups often operate through several underwriting companies, and each may have different complaint data. Also check the reasons behind complaints, such as claim delays or denials, which are usually more telling than billing issues.
AM Best: Can the Company Pay Claims?
Customer service means little if an insurer cannot pay its claims. AM Best is a credit rating agency that specializes in the insurance industry and assigns Financial Strength Ratings, which reflect its opinion of an insurer’s ability to meet its ongoing obligations to policyholders.
Ratings use letter grades, with the A range representing the strongest categories and lower grades indicating more vulnerability. You can usually look up a company’s rating on AM Best’s website after free registration, and many insurers list their rating on their own sites. Other agencies, such as S&P Global, Moody’s and Fitch, also rate some insurers.
Financial strength is especially important for long-term products like life insurance and annuities, where you may be counting on the company for decades. A rating is an opinion about the future, not a guarantee, so treat it as one important signal among several, and check whether the rating has recently been downgraded or placed under review.
Your State Insurance Department
Your state’s insurance department or commission is one of the most underused resources out there. Depending on your state, its website may offer:
- License verification for insurers and agents
- Complaint statistics or complaint ratios by company
- Consumer guides and rate comparison tools for auto or home insurance
- Information about enforcement actions
- A way to file a complaint if you have a dispute
Always confirm that a company and agent are licensed in your state before you buy. If an offer seems unusually cheap and you cannot verify the company, walk away.
Other Ways to Gauge Customer Satisfaction
- Ask friends and family about their actual claims experiences, not just pricing.
- Read customer reviews with healthy skepticism, focusing on patterns rather than single stories.
- Call the insurer with a few questions and notice how clear and patient the answers are.
- Check the digital tools: Can you file claims online? Track them? Reach a person easily?
- Ask an independent agent which companies tend to handle claims smoothly in your area.
Your Pre-Purchase Checklist
- Identify the exact company that will underwrite your policy.
- Check its AM Best financial strength rating.
- Look up its NAIC complaint index for your line of insurance.
- Review the relevant, most recent J.D. Power study for your region.
- Search your state insurance department’s site for licensing and complaints.
- Get quotes for identical coverage from several insurers.
- Weigh price against service and stability, not price alone.
Bottom Line
Top-rated insurance companies are not defined by advertising but by evidence: satisfied customers, few complaints relative to their size and strong finances. Use J.D. Power studies, the NAIC complaint index, AM Best ratings and your state insurance department together for a well-rounded view. Results vary by state, product and year, so check current data for your exact policy and talk to a licensed agent if you want help interpreting what you find.
Frequently asked questions
What is a good NAIC complaint index score?
A score below 1.00 means the company received fewer complaints than expected for its market share, while a score above 1.00 means more. Compare scores for the specific line of insurance you are buying.
Is AM Best the same as customer satisfaction?
No. AM Best rates financial strength, meaning an insurer's ability to pay claims, while J.D. Power and complaint data reflect customer experience. You should look at both.
Where can I file a complaint against an insurance company?
Contact your state insurance department, which handles consumer complaints and can investigate disputes. Try resolving the issue with the insurer first and keep records of all communication.
