How to Dispute a Utility Bill in California - and What PG&E, SCE, and SDG&E Are Required to Do About It
How do I dispute a utility bill with PG&E, SCE, or SDG&E in California?
Start by filing a formal written complaint with your utility - PG&E, SCE, or SDG&E - documenting the specific charges you're disputing and requesting a written explanation of how your bill was calculated. If the utility's response doesn't resolve the issue, escalate to the California Public Utilities Commission's Consumer Affairs Branch at cpuc.ca.gov, which can mediate the dispute at no charge.
Can my California utility shut off power while I'm disputing a bill?
Generally, California rules protect customers from disconnection over the specific portion of a bill they've formally disputed with the CPUC's Consumer Affairs Branch while that complaint is pending. You're typically still required to pay the undisputed portion of your balance. Customers on CARE or FERA discount programs have additional required notice steps before disconnection can occur.
How do I file a complaint against my utility company in California?
California residents with investor-owned utilities - PG&E, SCE, or SDG&E - can file a complaint with the California Public Utilities Commission's Consumer Affairs Branch online or by phone through cpuc.ca.gov. Municipal utility customers, such as those served by LADWP or SMUD, are not covered by the CPUC and should contact their utility's customer service or local city council instead.
What can cause a sudden spike in my California utility bill?
A sharp, unexpected increase in your bill's reported energy usage - without a corresponding change in your home's actual consumption - often points to an estimated meter read that corrected all at once, a faulty meter, or a billing system error. You can ask your utility to inspect the meter; the first test is often free, but some utilities charge a fee if the meter tests within normal operating range.
How far back can I get a billing correction from my California utility?
The look-back window for billing adjustments varies by utility and rate schedule, so there's no single statewide answer. If you believe you've been overbilled for several months, ask your utility in writing whether a retroactive adjustment applies to your account and under which tariff rules. The CPUC's Consumer Affairs Branch can also help clarify what corrections are available in your specific situation.

California utility bills have climbed sharply over the past several years, and billing errors - misread meters, rate misapplications, estimated bills that don't get corrected - are more common than most customers realize. If your bill looks wrong, you have formal rights under state law, and the process for pushing back is more structured than simply calling customer service and hoping for the best.

Start With the Utility Itself
Every major investor-owned utility in California - Pacific Gas and Electric, Southern California Edison, and San Diego Gas and Electric - is required by the California Public Utilities Commission to have a formal complaint process. Your first step is filing a written complaint directly with your utility, not just a phone call to the billing department. Document everything: the dates you contacted them, the names of any representatives you spoke with, and the specific charges you're disputing. Request, in writing, an explanation of how your bill was calculated, including whether it was based on an actual meter read or an estimate.
Utilities are generally required to investigate and respond to a formal complaint within a set timeframe. If you believe a billing error goes back several months, ask specifically about whether a billing adjustment applies - California rules generally allow customers to seek corrections on bills that were demonstrably wrong, though the look-back window and process vary by utility and rate schedule. Get any resolution offer from the utility in writing before agreeing to a payment arrangement.
What to Check Before You Escalate
Before taking a dispute to regulators, it helps to understand what you're actually disputing. Pull the last three to six months of bills and look for sudden unexplained jumps in kilowatt-hours or therms, which can indicate a meter problem rather than a rate issue. If your home's usage hasn't changed significantly, a spike in consumption almost always points to either an estimated read that corrected all at once, a faulty meter, or a billing system error. You can ask your utility to inspect the meter at no charge initially - though some utilities may charge a fee if the meter tests within normal operating range, so ask about that fee before requesting the test. Your rate classification also matters: if you're in a higher tier or on a time-of-use schedule and weren't properly notified of a rate change, that's a disputable billing issue, not just a market reality.
Escalating to the California Public Utilities Commission
If the utility's response doesn't resolve the dispute to your satisfaction, the California Public Utilities Commission handles formal complaints against the state's investor-owned utilities. The CPUC's Consumer Affairs Branch can informally mediate between you and the utility - this is often faster than a formal proceeding and resolves many billing disputes without needing a full hearing. You can reach the Consumer Affairs Branch by phone or file a complaint online through the CPUC's website at cpuc.ca.gov. The CPUC also handles complaints about service quality, deposits, and disconnection practices, not just billing math.
For a formal complaint that could result in a binding order - say, if the utility is consistently applying the wrong rate class to your account or you're seeking a larger retroactive adjustment - the CPUC has a separate formal complaint process that functions more like an administrative proceeding. That path is slower and more involved, and for complex cases, the CPUC recommends looking into its Public Advisor's office, which helps customers understand their options without charging a fee.

Disconnection Protections While a Dispute Is Pending
California rules provide some protection against disconnection while a billing dispute is being actively investigated. If you've filed a complaint with the CPUC's Consumer Affairs Branch, your utility generally cannot disconnect you over the disputed portion of the bill while that complaint is pending resolution - though you're typically still expected to pay the undisputed portion of any balance due. This is worth knowing if a dispute is dragging out and you're concerned about a shutoff notice. The CPUC has also established baseline seasonal protections for medical baseline customers and separate rules around "care" status that can affect when and how disconnections are carried out. If you're on the CARE or FERA low-income discount program, your utility's disconnection process has additional required notice steps before service can be cut.
If You're a Municipal Utility Customer
The CPUC's jurisdiction covers investor-owned utilities - PG&E, SCE, and SDG&E - but not municipal utilities like the Los Angeles Department of Water and Power, Sacramento Municipal Utility District, or the roughly two dozen other city- or publicly-owned electric systems in California. If you're a municipal customer, your dispute process runs through the utility's own customer service and, if needed, your city council or utility board, since those entities are locally governed rather than state-regulated. Check your utility's customer service information directly for the steps that apply to your account.
This is general information, not legal or financial advice. Utility billing rules, dispute timelines, and disconnection protections can change; verify current processes and file complaints with the California Public Utilities Commission at cpuc.ca.gov, or contact your specific utility's customer service department directly for account-level guidance.
