How to Dispute a Utility Bill in California: What PG&E, SCE, and SDG&E Customers Can Actually Do
how do I dispute a utility bill in California
California utility customers should first call their utility - PG&E, SCE, or SDG&E - and open a formal billing dispute, documenting the date and case number. If the utility doesn't resolve it, file a complaint with the California Public Utilities Commission at cpuc.ca.gov. The CPUC can investigate and order a bill adjustment or refund at no cost to you.
can PG&E or SCE shut off my power while I dispute a bill
California has protections that can limit shutoff during an active billing dispute, though the exact scope depends on your circumstances. If a formal complaint is pending with the California Public Utilities Commission, shutoff protections may apply. Contact both your utility and the CPUC at cpuc.ca.gov directly to confirm what protections apply to your specific situation before withholding any payment.
does the CPUC handle complaints against LADWP or SMUD
No. The California Public Utilities Commission only regulates investor-owned utilities like PG&E, SCE, and SDG&E - not municipal utilities like the Los Angeles Department of Water and Power or Sacramento Municipal Utility District. Customers of municipal utilities need to use that utility's internal appeals process or contact their city council or local oversight board for unresolved disputes.
what documents do I need to file a utility complaint in California
When filing a billing complaint with the California Public Utilities Commission, bring copies of the disputed bills, a written timeline of events, names and dates from any calls with your utility, and any written responses you received. The more documentation you have - including prior bills and usage history for comparison - the better positioned you'll be to support your case.
what is an estimated meter read and can it cause a wrong bill
An estimated meter read, marked "E" on your bill rather than "A" for actual, means the utility calculated your usage based on historical averages rather than a real measurement. If your usage changed significantly that month, an estimate can be substantially off. You can request an actual read or, for smart meter customers, access day-by-day usage data online through your utility's account portal.
California utility bills have climbed steadily in recent years, and a billing error, an unexplained spike, or a disputed meter read can mean hundreds of dollars at stake. If you think your bill is wrong, you have more formal options than simply calling customer service and hoping for the best. California law gives utility customers a structured path to challenge a bill, and a state agency has real authority to step in if your utility won't budge.

Start With Your Utility's Formal Dispute Process
Before going to regulators, you have to give your utility a chance to resolve it. That's not just courtesy - it's a required step under California Public Utilities Commission (CPUC) rules. Call the customer service number on your bill and ask specifically to open a formal billing dispute or complaint, not just an inquiry. Write down the date, the representative's name, and whatever case or reference number they give you. Follow up with an email or written letter so you have a paper trail.
PG&E, SCE, and SDG&E are all required to investigate and respond to billing complaints within a reasonable timeframe. If your usage spike was caused by an estimated meter read rather than an actual one, ask the utility to send someone to take a real reading or, depending on your setup, request access to your smart meter data to compare daily usage. In some cases, utilities will offer a bill adjustment or payment plan while the dispute is open - ask about that explicitly. You are not required to pay the disputed portion while a formal complaint is pending, but this depends on your specific situation and you should confirm that policy directly with your utility before withholding payment.
File a Complaint With the CPUC
If your utility doesn't resolve the dispute to your satisfaction, the California Public Utilities Commission is your next stop. The CPUC regulates PG&E, SCE, and SDG&E and can order a utility to adjust a bill, refund an overcharge, or take corrective action. You can file a complaint online at cpuc.ca.gov, by phone through the CPUC's consumer affairs branch, or by mail. There's no fee to file.
When you file, include everything: copies of the bills in question, a timeline of what happened, names and dates from your calls with the utility, and any written responses you received. The more documentation you have, the stronger your case. The CPUC will contact the utility on your behalf and, in most cases, a utility representative will reach back out to you with a more senior-level response. If the issue still isn't resolved after that, you can request a formal hearing before a CPUC administrative law judge - a process the agency calls an "Informal Complaint" escalating to a "Formal Complaint."
For municipal utilities - Los Angeles Department of Water and Power, Sacramento Municipal Utility District, and others that are city-owned rather than investor-owned - the CPUC does not have jurisdiction. Those customers need to go through their utility's internal appeals process and, if needed, their city council or a local utility oversight board.
What to Look for in Your Bill Before You File
A few specific things are worth checking before you decide whether to dispute. An estimated read, noted on your bill as "E" rather than "A" for actual, can be significantly off if your usage changed. A meter exchange or upgrade can occasionally result in an opening read error. If you're on a tiered rate structure and your bill jumped, check whether your household added a new appliance, an electric vehicle charger, or a second refrigerator - something that shifted you into a higher usage tier. If you're on a time-of-use rate plan, check whether your usage patterns changed or whether there was a rate schedule change you may not have noticed.

California's major investor-owned utilities are required to provide detailed usage history, and smart meter customers can usually access day-by-day usage data online. Comparing your current month against the same month in prior years can help you identify whether a spike is real or an error. If a leak is suspected - a running toilet or irrigation system issue - that's your utility company's billing department's likely first response, so it's worth ruling out before you file.
If You Can't Afford the Bill While You Dispute It
California law prohibits utilities from disconnecting residential service without proper notice, and there are protections for certain customers - including people with medical conditions that require powered equipment, low-income households, and customers actively engaged in a billing dispute. If you're worried about shutoff, ask your utility explicitly about its medical baseline, life support, or serious illness protections and about its low-income payment plan options. The CARE and FERA discount programs offered by PG&E, SCE, and SDG&E can reduce your base bill substantially if you qualify by income - those programs are separate from a billing dispute but worth applying for at the same time if you haven't already.
The CPUC also has a rule - generally referred to as the "no-shutoff during dispute" protection - that applies when a formal complaint is actively pending. Ask both your utility and the CPUC to confirm whether this applies to your specific situation, because the exact scope of that protection depends on the circumstances.
This is general information, not legal or financial advice. Billing dispute rules, protections, and processes can change, and your specific situation may depend on which utility serves you and whether it's investor-owned or municipal.
