The Years-Old Meter Error That Lands Ohio Households With a Back Bill
An Ohio electric or gas company can bill a household for only 365 days of an unmetered amount, no matter how long the meter was wrong.
The error can run for years. The bill can’t.
The rule has more turns in it than that, and not every account gets the same protection.
This is the years-old meter error that lands Ohio households with a back bill.
Note: This is general information, not legal advice. Ohio’s utility billing rules are subject to change, so confirm the current requirements with the Public Utilities Commission of Ohio.
How a Meter Error Runs for Years
A faulty meter in Ohio can run wrong for years before anyone catches it.
State rules require an electric or gas company to take an actual reading of a meter, not just an estimate.
Electric utilities owe that actual reading at least quarterly.
Gas utilities get a longer floor, an actual reading at least once every twelve months.
Between those checks, the company can fill in an estimated bill instead.
Nobody double-checks the guess.
Estimated bills carry a small marker on the page.
Almost nobody stops to check for that marker.
A gear that reads a little low, or an aging meter that slowly loses accuracy, can keep producing believable estimated bills for years.
Nobody catches it until a technician pulls an actual number or a homeowner asks for a test.
None of this is a shutoff notice or a rate hike.
It’s a mistake that sits unnoticed on the account until somebody finally reads the meter right.
The 365-Day Limit on What You Owe
Ohio law sets a hard limit the moment a company fixes a meter error.
An electric or gas company can only bill a residential customer for the unmetered amount from the 365 days immediately before the company remedies the mistake.
Say a meter has been reading a little low for six years.
The company still can’t reach back six years for the shortfall.
It can only bill for the last year of it.
The rest of the undercharge, everything older than a year, is simply gone.
Ohio lawmakers wrote that cutoff into state law decades ago.
It applies the same way whether American Electric Power’s Ohio utility (AEP Ohio), Duke Energy Ohio, Columbia Gas of Ohio, or Enbridge Gas Ohio sends the bill.
The math still holds.
Why a Small Business Gets a Longer Clock
A small business in Ohio doesn’t get the same 365-day protection a household does.
The state law that caps the residential clock at a year applies to residential customers only.
Separately, a PUCO rule sets a longer window for everyone else.
A small commercial account can be back-billed for up to 36 months of undercharged service once the company finds and fixes the error.
The clock triples.
A diner, a hair salon, or a small law office running on the same faulty meter for years can end up owing for nearly all of it.
Businesses don’t get the household’s shorter clock.
The 365-day protection is written as a consumer law, and a small business account simply falls outside it.
Ohio’s rule also spreads that longer back bill across the same stretch it covers, so a 36-month undercharge still lands in monthly pieces instead of one lump invoice.
The Law’s Required Payment Plan
Ohio law doesn’t stop at capping how far back a household’s back bill can reach.
It also caps how fast the company can collect it.
A residential undercharge from a meter error has to spread across 12 consecutive months instead of landing as one lump bill.
That spread is intentional.
Gas customers hold an extra layer of protection.
The company has to tell them, in writing, that they have the right to pay the undercharge back over those 12 months in equal installments.
Ohio’s 12-Month Payment Math
Say a meter mistake left an Ohio household owing $600 once the company found and fixed it.
State law caps the monthly collection at one-twelfth of that total.
The company can bill no more than $50 a month for a full year.
A bigger back bill spreads the same way, always divided across 12 consecutive months for a residential account.
This doesn’t shorten the 365-day cap on how far back the error can reach.
It only slows down how fast the company can collect what’s left.
When the Limit Doesn’t Apply
None of Ohio’s back-billing limits protect a customer whose meter was tampered with.
The 365-day cap, the 36-month commercial window, and the 12-month payment spread all carry the same carve-out.
Tampering voids all of it.
An unauthorized reconnection after a shutoff works the same way.
In either case, the company can pursue the full unmetered amount with no lookback limit at all.
The protections in this article exist for an honest meter that simply drifted or was misread, not for a meter someone deliberately altered.

The Utilities, and How to Push Back
AEP Ohio, Duke Energy Ohio, and FirstEnergy’s Ohio utilities follow PUCO’s electric meter rules.
Columbia Gas of Ohio and Enbridge Gas Ohio (formerly Dominion Energy Ohio) follow the matching gas rules.
The numbers line up the same way on both sides.
Any of them has to test a meter within 30 business days of a customer’s request.
The company covers the cost.
The first accuracy test costs a customer nothing.
The company can’t charge a testing fee at all if the meter turns out to be wrong.
A customer or their representative can stand right there and watch the test happen.
The company also has to explain the result in writing within ten business days.
If the test comes back outside tolerance, the company has to replace or recalibrate the meter at no charge to you.
A resolved test also resets things going forward, since every future bill counts on the new meter.
