How to File a Complaint Against Liberty Mutual
Policyholders may need to complain about a claim, billing issue, cancellation, premium increase, coverage dispute, repair process, customer-service interaction, roadside service, or another insurance matter. Before escalating, keep the policy number, claim number, correspondence, bills, photographs, repair estimates, adjuster information, and previous contact dates.
Step 1: Contact Liberty Mutual Customer Service or Claims
For general policy issues, call 1-800-290-8206. For an active claim, call 1-800-225-2467, which is available 24/7. Explain the concern clearly and provide your policy and claim information. Ask the representative or adjuster to document the issue, explain the applicable policy terms, and state what additional information is needed to reach a decision.
Step 2: Request Supervisor or Claims Management Review
If the first representative cannot resolve the issue, request review by a supervisor, claims manager, or appropriate policy-service leader. Provide the earlier case history, dates, adjuster communications, repair estimates, photographs, and any policy language relevant to the dispute. Keep notes of each conversation and obtain written explanations where possible.
Step 3: Use Liberty Mutual’s Formal Complaint Channel
Liberty Mutual publishes PSTwebform2020@libertymutual.com for complaints and general feedback. Send a concise summary that includes your full name, policy number, claim number if applicable, prior contacts, relevant dates, disputed amounts, and the resolution you are requesting. Attach copies of supporting documentation rather than originals.
Step 4: Send Formal Written Correspondence to Headquarters
For a serious unresolved corporate matter, send written correspondence to Liberty Mutual Insurance, 175 Berkeley Street, Boston, MA 02116. Include your contact information, policy and claim details, prior complaint history, relevant documents, and a chronological explanation of the problem. Keep proof of delivery and copies of everything submitted.
Step 5: Contact the Appropriate Insurance Regulator if Necessary
If the dispute remains unresolved, policyholders can contact the insurance department or insurance regulator in the state where the policy was issued. State regulators commonly handle complaints involving claims practices, cancellations, premiums, coverage administration, and insurer conduct. Payment disputes or suspected fraud may involve additional agencies depending on the circumstances. Preserve the policy, claim file, correspondence, repair records, complaint emails, and Liberty Mutual’s written responses before escalating.
