File a Complaint or a Comment
The Public Utilities Commission (PUC) is available to assist consumers. If you have a question about or are experiencing a problem with a PUC regulated industry, staff is available to talk to you and offer assistance between 8:00 a.m. and 5:00 p.m., Monday through Friday. Please call the PUC Consumer Line at 303-894-2070 or 1-800-456-0858, if calling outside the Denver metro area, but within Colorado.
Consumers are asked to first attempt to resolve problems directly with their utility. The utility will usually try to resolve the problem. However, if after doing this, the problem is not resolved, the PUC will assist consumers. Please click on the link below to access the online complaint form for the appropriate type of utility. Staff will review the submitted complaint and contact the complainant.
