What is cash heating oil? Cash heating oil is fuel you order when you choose and pay for at delivery, usually from a will-call or COD dealer posting a lower price per gallon than full-service companies. You give up automatic delivery, service contracts and budget plans, and no federal survey measures the discount.
Key Takeaways
- EIA’s US residential price rose from $3.555 a gallon on October 6, 2025 to $5.535 on March 30, 2026 (EIA weekly series).
- EIA’s reported price “should not reflect any discounts such as those given to cash or high-volume purchasers” (EIA respondent FAQ).
- 4.93 million US homes heated mainly with fuel oil or kerosene in 2020; 4.07 million were in the Northeast (EIA RECS 2020).
- A Northeast oil-heated home used about 538 gallons in 2020, by our conversion of RECS consumption data.
- Maine allows a surcharge of up to $20 on small scheduled orders (Maine Attorney General).
- Connecticut requires prebuy plans to be secured by supply covering 80% of gallons or a bond of 50% of funds (CGS 16a-23n).
What is cash heating oil, and how is it different from full-service delivery?
Cash heating oil is No. 2 fuel oil sold on a will-call basis: you watch your own tank, place an order, and pay at or before delivery. The dealer runs no service department and carries no customer credit, which is the usual case made for its lower posted price.
A full-service dealer sells the same fuel inside a bundle: automatic delivery on a schedule it sets, a burner service contract, emergency repair, and budget, capped or prebuy pricing.
| Feature | Cash or COD (will-call) | Full-service (automatic) |
|---|---|---|
| Who tracks the tank | You, by reading the gauge | The dealer |
| Payment | At or before each delivery | Invoice, budget, capped or prebuy plan |
| Burner service | Hired separately | Often a service contract |
| Small orders | May carry a surcharge | Dealer sets the drop size |
| Run-out risk | Yours | Mostly the dealer’s |
Tank ownership decides whether you can shop at all, because a leased tank ties you to one supplier. Our guide to oil tank sizes and replacement covers what owning one involves.
What did federal data show for cash heating oil’s benchmark price last season?
The benchmark for any cash heating oil quote is EIA’s weekly residential price, which climbed from $3.555 a gallon on October 6, 2025 to $5.535 on March 30, 2026. That is a rise of $1.98, or 55.7%, by our arithmetic.
EIA collects the price, excluding taxes, every Monday from October through March with participating states under the State Heating Oil and Propane Program (SHOPP). Our heating oil price tracker carries the full history and the March spike.
| Area | Oct 6, 2025 | Mar 30, 2026 | Season average (ours) |
|---|---|---|---|
| United States | $3.555 | $5.535 | $4.011 |
| Connecticut | $3.415 | $5.546 | $3.948 |
| Maine | $3.278 | $5.371 | $3.726 |

Dollars per gallon, excluding taxes. Season average is our simple mean of the 26 weekly readings; EIA publishes no volume-weighted season figure.
On March 30, 2026, New York’s average sat 71.4 cents above Pennsylvania’s: location sets the price level before the delivery model does. See the federal outlook for this winter’s heating bills for the season ahead.
Why is the cash heating oil discount missing from federal data?
The cash heating oil discount is missing because EIA excludes it by design. EIA’s guidance tells reporting dealers the price “should not reflect any discounts such as those given to cash or high-volume purchasers,” so the federal average is the full posted price.
The EIA-877 form instructions add that dealers report a price “excluding all taxes” for customers “with storage tanks of approximately 275 gallons,” leaving out “any discounts or premiums paid for small or large volume purchases.”
The data gap, stated plainly
No federal agency publishes the price COD dealers charge, the size of the cash discount, or how many households buy on will-call. Any “cash price” average you see comes from a private listing site or a dealer, and we do not treat those as data. EIA’s respondent guidance is the reason.
How much can a cash heating oil discount save in a season?
A cash heating oil discount saves about $54 a season for every 10 cents off per gallon in a typical Northeast oil-heated home, by our arithmetic. The saving scales with the discount and with the gallons the house burns.
Northeast homes that used fuel oil burned an average of 74.5 million Btu of it in 2020, per EIA’s Residential Energy Consumption Survey. At 138,500 Btu per gallon, that is about 538 gallons, or $2,158 before taxes at last season’s $4.011 average.
- Total last season’s delivery tickets for your own gallons.
- Get the COD and full-service prices on the same day, for the same order size.
- Multiply the gap by your gallons.
- Subtract what full service included: a tune-up, small-order surcharges, any restart charge.
Fuel price is half of what heat costs. Our comparison of delivered heat cost by fuel and system places oil against gas, propane and heat pumps, and a winter thermostat setback cuts gallons whoever fills the tank.
What does will-call delivery give up?
Will-call delivery gives up a dealer watching your tank, a dealer obliged to warn you before deliveries stop, and the large drop that avoids small-order fees. New York’s consumer guide says that unless you are on automatic delivery, “the consumer must monitor the supply level of the tank and order fuel accordingly.”
Under New York rule 9 NYCRR 7870.3, from November 1 through April 15 an automatic-delivery customer gets written notice at least three days before deliveries stop, plus three phone attempts. Companies are not required to give will-call customers advance notice of shut-off, according to the state’s home heating guide.
In Maine, an order under 50% of tank capacity or 100 gallons, whichever is less, can carry a surcharge of up to $20, so a standard 275-gallon tank needs orders of at least 100 gallons. The Maine Attorney General also warns: “Don’t let your furnace run dry. This could cause damage to your furnace that would be expensive to repair.” No federal source prices a run-out service call, so we publish no figure.
A cash buyer also books the annual tune-up separately; see what an oil boiler service or an oil furnace maintenance visit should cover.
- Read the float gauge weekly in cold weather.
- Reorder early enough to ride out a peak-season delivery wait, above any small-order threshold.
- Keep every delivery ticket; New York requires receipts showing date, price per gallon and gallons.
- Book burner service before the season.
Are budget plans and prebuy contracts better than cash heating oil?
Budget plans and prebuy contracts beat cash heating oil only when they move price risk to the dealer at a fair premium. Last season the US price rose 55.7% between October and late March, so early locks won; in a falling season the same lock loses.
New York’s guide defines the options: a market price is “the prevailing price of heating fuel at the time of delivery,” a capped price “may vary, but it may not exceed the specified amount,” and budget billing spreads estimated use over 12 payments.
| Plan | Who carries price risk | Connecticut rule |
|---|---|---|
| Cash or will-call | You, delivery by delivery | Advertised price must hold 24 hours |
| Budget plan | You; payments smoothed, not price | At least three installments over 120 days |
| Capped price | Dealer above the cap | Contract must say how the price falls |
| Prebuy (prepaid) | Dealer, but you risk dealer failure | 80% supply cover or 50% bond within five business days |
Connecticut’s Chapter 296a, enforced by the Department of Consumer Protection, requires every heating fuel dealer to register. Section 16a-23n requires written contracts, caps commitments at 18 months, bans automatic renewal, and requires a refund for undelivered fuel within 30 days of the end date unless the parties agree otherwise.
Judge any contract on the premium over the dealer’s market price, the gallons you must take, what secures prepaid money, and how the price falls if the market drops.
Who heats with oil, and where?
About 4.93 million US homes heated mainly with fuel oil or kerosene in 2020, and 4.07 million were in the Northeast, according to EIA’s Residential Energy Consumption Survey. That is about 18.6% of the region’s 21.92 million homes, by our arithmetic.
New England had 1.94 million and the Middle Atlantic 2.12 million. EIA’s heating oil explainer counts about 4.79 million oil-heated households in the winter of 2023-2024, about 82% in the Northeast. Of Northeast oil homes, 1.44 million use a steam or hot water system, covered in our explainer on boiler and baseboard heat.
Households weighing a switch can compare propane heating systems and cold-climate heat pumps.
Should you buy cash heating oil or stay with full service?
Buy cash heating oil if you own the tank, read the gauge reliably, have a separate service company, and the per-gallon gap times your gallons beats that service cost. Stay with full service if someone in the house is vulnerable to a cold night, you travel often, or a contract or leased tank ties you in.
Some households split the two, keeping a service-only contract and buying fuel on will-call. Our explainer on what a maintenance plan covers helps price that service piece.
How we researched this
Research date: October 5, 2026. Every price comes from EIA’s weekly residential No. 2 heating oil series, 2025-26 season (October 6, 2025 to March 30, 2026, released April 1, 2026). Household counts come from RECS 2020 (final release March 2023) and EIA’s heating oil explainer. Legal points come from Connecticut Chapter 296a, New York’s Division of Consumer Protection guide (May 2024) and Maine’s Attorney General. Gallon conversions, averages and discount scenarios are our arithmetic, labelled as ours. Freshness: one 2026 price series, a 2020 survey, a 2023 to 2024 count and current state rules; we consulted 14 sources and cited 10.
Excluded: private price-listing sites, dealer price boards and run-out repair price claims, because none is a federal or national-lab series. Reddit was not used. Update schedule: prices refresh with each EIA weekly release from October 7, 2026.
Frequently asked questions
Is cash heating oil cheaper?
No federal series can say by how much. EIA tells dealers its price “should not reflect any discounts such as those given to cash or high-volume purchasers.” Compare a COD quote with EIA’s state average, which was $5.546 in Connecticut and $5.874 in New York on March 30, 2026.
What does COD mean for heating oil?
COD means cash on delivery: you pay when the oil arrives, or before, rather than on an invoice or plan. COD dealers usually deliver only when you call. New York’s consumer guide notes that customers outside automatic delivery must monitor their own tank and order fuel accordingly.
What is the minimum heating oil delivery?
It depends on the dealer and the state. In Maine, a scheduled order under half the tank or 100 gallons, whichever is less, can carry a surcharge of up to $20, so a 275-gallon tank owner should order at least 100 gallons. Ask any COD dealer for its minimum before ordering.
How much heating oil does a house use in a winter?
Northeast homes heating with fuel oil used an average of 74.5 million Btu of it in 2020, according to EIA’s RECS. At EIA’s 138,500 Btu per gallon, that is about 538 gallons by our conversion. A colder winter, larger house or older boiler pushes the figure up.
Is a heating oil prebuy contract worth it?
Only if prices rise after you lock and the dealer delivers. Last season the US weekly price rose 55.7% from October 6, 2025 to March 30, 2026, which favoured early locks. Connecticut requires prebuy plans to be secured by supply covering 80% of committed gallons or a bond of 50% of funds.
What happens if you run out of heating oil?
The heat stops until fuel arrives and the burner restarts. Maine’s Attorney General warns that letting a furnace run dry “could cause damage to your furnace that would be expensive to repair.” New York requires advance shut-off notice for automatic-delivery customers from November 1 to April 15, but not for will-call customers.
