How to File a Complaint Against Duke Energy

Step 1: Contact Duke Energy Customer Service

Begin with the customer-service number for your service territory.

For example, Duke Energy Carolinas customers can call:

800-777-9898

Explain whether the complaint involves billing, service, payment, outage handling, meter issues, or another concern.

Step 2: Provide Your Account Details

Have your account number and service address ready.

Explain the problem clearly and provide dates, charges, payments, meter information, or outage details when relevant.

Step 3: Request Further Review

If the first representative cannot resolve the matter, ask for supervisory or additional review.

Keep records of:

• Customer-service case numbers
• Utility bills
• Payment confirmations
• Emails
• Screenshots
• Outage information
• Dates and times of calls
• Names of representatives

Step 4: Use Duke Energy’s Online Account System

Customers can also use Duke Energy’s digital customer-service tools to review bills, account information, payment history, and service details.

Using the authenticated account system can help document the issue.

Step 5: Contact Duke Energy Corporate Headquarters

For a serious unresolved corporate matter, correspondence may be sent to:

Duke Energy Corporation
525 South Tryon Street
Charlotte, NC 28202
United States

Routine utility-service matters should normally go through regional Customer Service before being escalated to corporate headquarters.

Step 6: Contact the State Utility Regulator

Electric and natural gas utilities are regulated at the state level.

If a billing, service, disconnection, meter, or utility-practice complaint remains unresolved, customers may contact the public utilities commission, public service commission, or equivalent regulator responsible for their state.

Step 7: Report Safety Emergencies Immediately

Do not use the ordinary complaint process for urgent electrical or gas hazards.

Downed power lines, electrical emergencies, suspected gas leaks, or other immediate safety threats should be reported through Duke Energy’s emergency channels or local emergency services immediately.
