Electric provider slamming is when a retail energy supplier switches your account away from your current provider without your permission, and you can reverse it by disputing the switch with the supplier, your local utility, and your state’s public utility commission. It only happens in the roughly 18 states plus Washington, D.C. that have deregulated retail electricity, because those are the markets where a third party can take over the supply side of your bill using little more than your account number. Both federal and state rules give you the tools to unwind the switch, recover overcharges, and avoid the early termination fees a slamming supplier may try to impose.
Signs Your Electric Supplier Was Switched Without Your Consent
Your delivery charges keep coming from the same local utility even after a slam, so the tell sits in the supply charges section of the bill. A new company name there is the clearest signal. A sudden jump in your per-kilowatt-hour rate with no change in usage is the second.
Many people catch it a different way: the original utility mails a notice confirming a supplier change the customer never asked for. Others notice only when an early termination fee appears from a company they don’t recognize. Any letter, email, or bill referencing a new energy contract you don’t remember signing should be treated as a slam until you can prove otherwise.
How Slammers Get Access to Your Account
The most common approach is a telemarketer or door-to-door representative who asks to see a copy of your utility bill, usually claiming they need to verify savings or check eligibility for a government discount. The real target is the account number printed on the bill. Once they have it, they can submit a switch request without any further interaction with you.
Some operations go further and fabricate the third-party verification recording that’s supposed to prove consent. An FCC enforcement document on carrier switching fraud describes fraudulent companies splicing a consumer’s voice from an unrelated call into a fake verification, coaching consumers to answer “yes” to every question without explaining what they were agreeing to, and running pretextual “courtesy calls” purely to capture recorded voice responses they could edit later.1Federal Communications Commission. Protecting Consumers from Unauthorized Carrier Changes and Related Unauthorized Charges
Door-to-door representatives sometimes use tablets that display a single signature line while hiding the actual contract terms. You think you’re signing an information request or a consent to a rate quote; you’re authorizing a supplier switch. That’s exactly the scenario the federal cooling-off rule was written for.
The Laws That Protect You
There is no single federal statute that bans unauthorized switching of energy suppliers the way the Telecommunications Act of 1996 bans phone carrier slamming.2Federal Communications Commission. Slamming Policy Energy slamming is policed almost entirely at the state level, but two federal rules still apply and matter in a dispute.
State Public Utility Commission Rules
Enforcement lives with your state’s public utility commission (called a public service commission in some states). Most deregulated states require third-party verification before any supplier switch can go through. The verification must be a separate interaction from the sales pitch, conducted by an independent party, and it must record your consent to specific terms including the rate and any cancellation fees. If the supplier can’t produce a valid recording, the switch is treated as unauthorized.
Penalties vary. A common benchmark in commission enforcement actions is around $1,000 per unauthorized switch, and many states require the offending supplier to refund the full difference between what you paid and what your original rate would have produced. Early termination fees on a contract you never agreed to generally can’t be collected.
The FTC’s Three-Business-Day Cooling-Off Rule
If you signed anything during a door-to-door sales visit, federal regulations give you until midnight of the third business day after the transaction to cancel for any reason. The seller must give you a cancellation form at the time of sale, and Sundays and federal holidays don’t count toward the three days.3eCFR. Rule Concerning Cooling-off Period for Sales Made at Homes or at Certain Other Locations The rule covers door-to-door sales over $25, which is effectively every energy contract.4Federal Trade Commission. Cooling-off Period for Sales Made at Home or Other Locations Pressure at the door doesn’t cost you that window.
The FTC’s Telemarketing Sales Rule
The Telemarketing Sales Rule covers any plan using interstate calls to induce a purchase, and energy telemarketing falls inside it. It prohibits misrepresentations and unauthorized billing, restricts calls to numbers on the National Do Not Call Registry, requires specific disclosures during sales calls, and limits calling hours.5Federal Trade Commission. Complying with the Telemarketing Sales Rule A telemarketer who lies about who they are or what you’re agreeing to violates the rule regardless of state.
What Slamming Costs You
The immediate hit is the rate difference. Slamming suppliers almost always charge more per kilowatt-hour than your previous rate, sometimes far more, and over a few billing cycles the overcharges can reach hundreds of dollars before anyone notices. If the contract carries an early termination fee, you may see a charge of $100 to $200 for canceling something you never chose. State regulators generally void those fees in confirmed slamming cases, but you usually have to file a formal complaint to get the waiver applied.
Credit is the less obvious risk. Energy suppliers don’t typically report payment history to the credit bureaus, but if you refuse to pay the slammed supplier and the account goes to collections, the collections entry can appear on your credit report and stay there for seven years, even after you pay it off.6Consumer Financial Protection Bureau. A Summary of Your Rights Under the Fair Credit Reporting Act You don’t owe the money, but ignoring the bill while you fight the dispute can still damage your credit.
How to Reverse the Switch
Speed matters. Every additional billing cycle piles on overcharges and gives the unauthorized supplier more time to argue that your silence implied consent.
Step One: Call the Unauthorized Supplier
Demand immediate cancellation of the account and a full refund of any charges above what your original supplier would have billed. Get a confirmation number and the name of the representative. If they claim you authorized the switch, ask them to produce the third-party verification recording. A legitimate recording captures your voice clearly consenting to specific terms. A spliced, coached, or missing recording is your strongest piece of evidence.
Step Two: Call Your Original Utility
Ask to be switched back to standard utility service or to your previous supplier. Ask whether you qualify for billing adjustments that reflect your original rate during the slammed period. Some utilities apply those adjustments automatically once slamming is confirmed; others wait for the commission’s investigation to close.
Step Three: File a Complaint With Your State Public Utility Commission
This is the step that actually forces an investigation. Every deregulated state’s commission has an online complaint portal. Before you file, gather:
- The unauthorized supplier’s name and your account number with them, both printed on the bill showing the new charges
- The exact date the switch took effect, usually shown on the first bill from the new supplier
- Your original utility account number, which the commission uses to trace the switch request
- A log of interactions with sales representatives, including names, dates, and what was said on calls or at the door
- Copies of written communications, including the utility’s notice of switch letter and any contract you were asked to sign
In the complaint narrative, focus on the absence of valid authorization. State plainly that you did not request the switch, did not sign a contract, and did not participate in a third-party verification call. If a salesperson misrepresented themselves, quote what they said as closely as you can. Specifics carry weight with investigators. Vague statements about feeling pressured don’t.
After you submit, the commission assigns a tracking number and typically contacts the supplier for its side. Informal investigations generally wrap up within 30 to 60 days. If the commission finds the switch was unauthorized, it will usually order the supplier to refund the overcharges and restore your original rate.
Protecting Your Credit While the Dispute Is Pending
The gap between filing and resolution can span two or three billing cycles. During that time, the unauthorized supplier may keep billing you and may eventually route the unpaid balance to collections.
If a collections account tied to a slammed supplier lands on your credit report, dispute it directly with the credit reporting agency. Under the Fair Credit Reporting Act, the agency must investigate within 30 days and either verify, correct, or delete the entry. Adding information mid-investigation gives the agency up to 15 extra days, but unverifiable items must be removed.7Office of the Law Revision Counsel. 15 U.S. Code 1681i – Procedure in Case of Disputed Accuracy Attach your state commission complaint and tracking number to the dispute so the agency has documentation that the underlying debt is contested through an official process.
If you think the slam was part of broader identity theft, place an initial fraud alert on your credit file. It lasts one year and requires businesses to verify your identity before extending new credit in your name.6Consumer Financial Protection Bureau. A Summary of Your Rights Under the Fair Credit Reporting Act
How to Keep It From Happening Again
Never share your utility account number with anyone who contacts you unsolicited. Legitimate suppliers don’t need to see your bill to explain their rates. If a door-to-door representative asks for your account number or hands you a tablet to sign, that’s the moment to end the conversation.
Make sure every adult in the household knows who your current supplier is and understands that no one authorizes a switch without a family conversation first. Slamming operations often target whoever answers, counting on any household member’s “yes” to hold up later.
Review the supply charges line on your bill every month. Catching an unauthorized switch on the first bill limits the financial damage and makes the complaint far easier to prove. Waiting several months gives the unauthorized supplier room to argue you consented by paying without objection.
