How to File a Complaint Against Your Insurance Company with the Regulator

When your insurance company denies your claim unfairly and won't reverse the decision, your next step is escalating to your country's insurance regulator. Regulators have the power to investigate complaints, determine whether insurance companies are following the rules, and compel insurers to pay wrongfully denied claims.

Filing a regulator complaint is free and doesn't require a lawyer. Here's how to do it in major countries and regions.

Understanding Regulators and What They Can Do

Insurance companies are regulated by government agencies in each country and region. These regulators:

  • License insurance companies
  • Set rules for how insurance operates
  • Investigate consumer complaints
  • Compel insurers to reverse decisions, pay claims, or compensate for wrongdoing
  • Can fine insurers for serious violations

When you file a complaint with a regulator, you're asking them to investigate whether your insurer violated regulations.

General Tips for Filing a Regulator Complaint

Regardless of your country:

Organize Your Information

Create a clear, numbered list of documents you're submitting. Reference them in your complaint letter by number. Make it easy for the regulator to follow your case.

Be Clear and Specific

Don't write a rambling narrative. Write clearly:

  • What happened (timeline)
  • Insurance's decision
  • Why you believe it was wrong
  • What you want (claim paid, investigation, etc.)

Provide All Supporting Evidence

Attach:

  • Denial letter
  • Your claim form and supporting documents you submitted
  • Medical records (if medical claim)
  • Correspondence with insurance
  • Your policy (relevant pages)
  • Any other supporting evidence

Complain First to Insurance (Usually Required)

Most regulators require you to file an internal complaint with insurance first and give them a reasonable chance (usually 30 days) to respond. Only then escalate to the regulator.

Keep It Professional

Don't vent emotions or use inflammatory language. Stick to facts. Professional complaints are more persuasive.

Request Specific Outcome

Be clear about what you want: "I request that [Regulator] investigate this complaint and determine whether insurance was justified in denying my claim. If not, I request the regulator order insurance to pay my claim of [amount]."

What Happens After You File

Once you file:

  1. Regulator acknowledges receipt
  2. Regulator contacts insurance company
  3. Insurance company provides their response
  4. Regulator investigates
  5. Regulator issues determination

If the regulator finds insurance was wrong, they can:

  • Order insurance to pay your claim
  • Order compensation for delays or mishandling
  • Fine the insurance company
  • Require policy changes

You don't need a lawyer. The regulator investigates for you.
