How to Dispute an Electricity Bill: A Step-by-Step Guide (2026)

Received an electricity bill that looks wrong? You’re not alone. Billing errors from both utilities and competitive electricity suppliers are more common than most consumers realize — and you have legal rights to dispute them. Whether it’s an estimated meter read that ran high, a fee that wasn’t disclosed in your contract, or a supplier that switched your rate without proper notice, this guide walks you through the dispute process step by step.

Step 1: Review Your Bill in Detail

Before calling anyone, understand exactly what you’re disputing. Pull out your current bill and compare it to the previous two or three months. Look for:

• Actual vs. estimated reads: If your meter was estimated (marked “E” or “EST” on the bill), the utility may have guessed high. An actual read next month will correct it, but you can request an immediate actual read.
• Rate changes: If you’re on a variable-rate plan with a supplier, your per-kWh rate may have spiked without notice — this is one of the most common complaints in deregulated states.
• New fees or charges: Look for delivery charges, capacity charges, or administrative fees that weren’t on prior bills. Compare against your supplier contract.
• Usage spike: A legitimate usage spike (hot summer, HVAC running overtime, a new appliance) isn’t a billing error — but it’s worth investigating before disputing.

Step 2: Identify Who to Contact — Utility or Supplier?

In deregulated states, your electricity bill often includes two components: delivery charges (billed by your utility — the wires company) and supply charges (billed by your competitive supplier). The dispute goes to whichever party made the error:

• Meter reading errors, delivery charges, outage billing: Contact your utility (e.g., ComEd, Oncor, PECO).
• Supply rate errors, unauthorized enrollment (slamming), undisclosed fees: Contact your competitive electricity supplier first, then your state’s Public Utilities Commission if they don’t resolve it.

If you’re unsure who to contact, start with whoever bills you — most utilities in deregulated states provide consolidated billing and can route the dispute internally.

Step 3: Gather Your Documentation

Before you call or write, collect:

• Your current bill and the past 12 months of bills (most utilities offer online account history)
• Your supplier contract or welcome letter, especially the rate schedule and disclosure document
• Any enrollment confirmation emails or letters
• Notes on dates, times, and names from prior phone calls

Documentation wins disputes. A caller who can say “I have your welcome letter dated October 3rd that shows a fixed rate of 8.4 cents/kWh — my current bill shows 14.2 cents” is far more persuasive than one who says “I think my rate went up.”

Step 4: Call Customer Service and Document Everything

Call the customer service number on your bill. When you call:

• Ask for the representative’s name and employee ID
• State clearly: “I’m disputing [specific charge] on my [month] bill for account [number]”
• Take notes with the time, date, what was said, and any reference or case number provided
• Ask what the resolution timeline is and get confirmation in writing if possible

Most straightforward disputes (estimated reads, obvious calculation errors) are resolved in a single call. Rate disputes with competitive suppliers often take longer.

Step 5: Escalate to a Written Formal Dispute

If the phone call doesn’t resolve the issue within 30 days, escalate in writing. Send a formal dispute letter via certified mail (or email, with read receipt) to the billing address. Your letter should:

• Reference your account number and the bill(s) in question
• Describe the error specifically and cite the contract language or rate schedule it violates
• State what resolution you’re requesting (credit, rate correction, refund)
• Include copies (not originals) of your supporting documents
• Set a 15-business-day response deadline

Step 6: File a State Regulatory Complaint

If the utility or supplier fails to resolve the dispute to your satisfaction, escalate to your state’s public utilities regulator. Every deregulated state has a consumer affairs division that handles electricity billing complaints:

• Texas: Public Utility Commission of Texas (PUC) — puc.texas.gov
• Illinois: Illinois Commerce Commission — icc.illinois.gov
• Pennsylvania: PA Public Utility Commission — puc.pa.gov
• New York: NY Public Service Commission — dps.ny.gov
• Ohio: Public Utilities Commission of Ohio — puco.ohio.gov
• New Jersey: NJ Board of Public Utilities — nj.gov/bpu

Filing a regulatory complaint costs you nothing and creates an official record. Suppliers and utilities take regulatory complaints seriously — they can result in fines, license reviews, and required customer remediation.

Common Billing Disputes and How They’re Typically Resolved

Estimated meter read that ran high: Request an actual read or self-read. The utility will adjust your next bill based on the true cumulative reading. If you overpaid by more than one month’s worth, you can request a direct credit.

Unauthorized supplier switch (slamming): You have the right to be switched back to your prior supplier or default service at no cost, plus a refund of any overcharges. Document everything and file a state complaint — slamming is illegal in all deregulated states.

Variable rate spike not disclosed: Review your contract’s rate change notification requirements. Most states require 30-day advance notice of rate changes. If the supplier didn’t provide proper notice, you may be entitled to the prior rate for the billing period in question.

Early termination fee (ETF) applied incorrectly: Compare the fee to your contract terms. If the supplier applied an ETF when you switched because they failed to renew properly, that’s a dispute worth escalating to the regulator.

How Long Does a Billing Dispute Take?

Most state regulations require utilities and suppliers to acknowledge a written dispute within 5–10 business days and resolve it within 30–60 days. Texas requires resolution within 21 business days. If you don’t hear back within the regulated timeframe, that failure alone is grounds for a state complaint.

During an active dispute, most states prohibit disconnection for the disputed amount. You typically still owe the undisputed portion of your bill — not paying everything can complicate your case.

Frequently Asked Questions

Can I withhold payment while disputing a bill?

Generally no — most states require you to pay the undisputed portion while the dispute is pending. Withholding the entire bill can trigger late fees or disconnection proceedings for the non-disputed amount, weakening your position.

What if my supplier has gone out of business?

Your state regulator is your first call. Most states have consumer protection mechanisms when a licensed supplier exits the market, including mandatory price protections and automatic return to default utility service. File a complaint with the regulator even if the company is defunct — there are often bonding or escrow requirements for exactly this situation.

Is there a deadline to dispute an electricity bill?

Most states have dispute filing windows, typically 1–3 years depending on whether the claim involves a contract breach or billing error. Check your supplier contract for any shorter contractual dispute deadlines — some contracts require written disputes within 90 days of the bill date.

Can a billing dispute affect my credit score?

Electricity bills themselves don’t report to credit bureaus, but unpaid bills sent to collections can. If you have an active dispute, document it carefully — a debt collector cannot legitimately collect a billed amount that’s under active regulatory review.

What’s the difference between a dispute and a complaint?

A dispute is the internal process with your utility or supplier. A complaint is an escalation to the state regulatory body when the internal process fails or takes too long. You don’t need to wait to exhaust the internal process to file a regulatory complaint — filing both simultaneously is allowed and often speeds resolution.
