Daylight saving time ends this Sunday, and with it goes the last stretch of cheap utility bills until April. That’s why every utility in the country is pushing utility budget billing right now: one flat payment, every month, no January shock. I like the idea. But most people sign up without asking the one question that decides whether the plan helps them or quietly sets them up for a spring bill they didn’t plan for. Where does the number come from?
At a lot of utilities, the answer is your last 12 months of bills. That means your flat payment this winter is priced off last winter. And this winter isn’t priced like last winter.
Budget billing never lowers your bill, it just moves the bill around
The plan itself is simple, and that simplicity hides the catch. You still pay for every kilowatt-hour and every therm you use. The utility just spreads the total into equal monthly pieces, then compares what you paid against what you owed once a year. That comparison is the budget billing true-up. If you underpaid, you owe the gap. If you overpaid, the utility has been holding your money.
None of that is a problem when prices sit still. It turns into one in a year like this, because the formula is looking in the rearview mirror while prices are moving.
This winter’s prices broke away from last winter’s in both directions
The federal numbers are unusually split this year. The U.S. Energy Information Administration’s Winter Fuels Outlook, released October 6, expects the average home heated with electricity to spend $1,196 this November through March, up 4% from last winter. Homes heated with natural gas are expected to spend $640, down 9%, mostly because last winter ran colder. Heating oil households are looking at $2,115, up 21%.
The Bureau of Labor Statistics backs up the electricity side. Its September 2026 Consumer Price Index shows electricity prices up 4.4% over the past 12 months, and fuel oil up 74.2%. The National Energy Assistance Directors Association is gloomier still: its September 14 forecast puts this winter’s average heating bill at $1,030, up 8.7%, with electric heat up 9%.
So electric and oil households are heading into a winter that costs more than the one their budget payment was built on. Gas households, at least on the EIA’s weather assumptions, are heading into one that costs less.
Your utility’s formula decides who eats the difference
Utilities don’t all build the number the same way, and the gap between methods is bigger than the brochures let on.
Dominion Energy in Virginia sets your budget amount from the average of your past 12 months of bills and normally recalculates it every 12 months. If you come up short at the annual review, you either pay the difference in full or roll it into next year’s amount. If you overpaid, the credit gets applied to next year. You need 12 months of history at your address to join, you can’t carry an old balance in, and a 1.5% late charge can hit any unpaid balance 25 days after billing.
CenterPoint Energy in Minnesota does it differently. It builds your gas payment from expected weather, projected gas prices, and your usage, then reviews it at the six-month mark and again before each new year. Any gap at year end gets divided by 12 and added to the next 12 payments. And if you held a credit balance for most of the year, CenterPoint pays you interest on it.
Those are two very different deals. A forward-looking plan like CenterPoint’s already has this winter’s prices baked in. A trailing-average plan like Dominion’s has last year’s.
A trailing average can leave electric homes $104 short on heat alone
Let me run it with the EIA’s own figures, looking only at the heating months.
If electric-heat spending is $1,196 this winter and that’s 4% higher than last winter, last winter came in around $1,150. A budget payment built on last winter is about $46 light for the season. That’s annoying but small. Now use NEADA’s 9% estimate instead: $1,150 grows to about $1,254, and your plan is roughly $104 short. Spread across a year, that’s an extra $9 a month you should be setting aside and probably aren’t.
Heating oil is the scary one. If $2,115 is a 21% jump, last winter was about $1,748, and a plan priced off it misses by about $367. That’s $30 a month.
Gas runs the other way. If $640 is 9% below last winter, last winter was roughly $703. A trailing-average plan collects about $63 more than you’ll owe on heat this season. You get it back eventually, usually as a credit against next year, but at most utilities that’s an interest-free loan from you to them. (CenterPoint’s interest on credit balances is the exception, and it’s worth knowing whether your utility does the same.)
Your house isn’t the national average, so read these as a sense of scale. The direction is the part that holds. Electric and oil heat: your flat payment is probably too low. Gas heat on a trailing average: probably too high.
Two minutes on the phone tells you which way your plan is wrong
Log in to your utility account or call, and ask exactly this: “Is my budget amount based on my past 12 months of bills, or on projected prices?” Then ask when the annual true-up happens and whether they pay interest on credit balances. Write the answers down. You’ll want them in April.
If you heat with electricity and the plan uses a trailing average, you have two options. Some utilities will let you raise your payment. If yours won’t, open a separate savings bucket and move $9 a month into it automatically, using the NEADA-sized gap as your cushion. When the true-up arrives, you pay it from the bucket instead of from your grocery money. If you heat with oil, your dealer’s budget plan works the same way, and our breakdown of heating oil pre-buy contracts walks through which lock-in terms are worth taking this year.
If you heat with gas and your utility uses a trailing average with no interest on credits, think hard about skipping the plan. Pay your actual bills, and put the $5 or so a month you’d have overpaid into savings yourself. You get the same smoothing, and the money stays yours.
Two Dominion-style traps catch people every year. Moving cancels the plan, and your full balance comes due right then. Missing a budget payment can get you removed from the plan, which also brings the true-up forward. If either is likely in your next 12 months, plan for it now.
When utility budget billing is worth it anyway
I’m not telling you to quit. In 2024, utilities shut off electric service about 13.4 million times for nonpayment, according to NEADA. Most of those shutoffs happen when one big winter bill lands on top of everything else. Utility budget billing removes that spike, and for a household whose January bill runs double its May bill, that’s worth a lot.
The plan just works better when you know which direction it’s wrong. Find out how your utility sets the number, match your cushion to your fuel, and the true-up becomes a non-event. If a bill has already gotten ahead of you, our guide to utility bill assistance programs covers the hardship plans most people never ask for.
