Filing a Formal Complaint with the CPUC

Before filing a formal complaint, please make sure you understand the following:

  • The CPUC has an informal complaint process that helps customers with complaints against utility companies under the CPUC's jurisdiction. This informal complaint process is handled by the CPUC's Consumer Affairs Branch. Please visit the CAB webpage to learn more about the informal complaint process.
  • If you find that the informal complaint process cannot help you or you wish to appeal the determination made at the end of the informal complaint process, then you may wish to file a formal complaint.
  • It is important to note that the CPUC is not allowed by law to award damages for such things as personal injury, property damage, emotional distress, or loss of wages or profits. To request compensation for damages, the customer can utilize the utility company's process or can file a claim in a civil court.

Here are the instructions and forms you need to file a formal complaint. Please be sure to read all of the instructions as they provide information on the two types of formal complaints and how the formal complaint process works. Moreover, Article 4 of the CPUC's Rules of Practice and Procedure provides the guidelines for formal complaints.
