Quick Answer
US home heating oil winter 2026-2027 will average $4.20-$4.80 per gallon, up 20-30% from $3.95 last winter (EIA STEO, September 2026). The average US household bill rises to $2,000-$2,400; Northeast households (MA, CT, RI, ME, NH, VT, NY, PA, NJ) face $3,500-$4,500 bills, up from $2,800-$3,500 last winter. The Saudi East-West pipeline shutdown adds upside risk — heating oil could hit $5.50-$6.00/gal if the pipeline stays shut through Q4 2026. Propane is forecast at $2.80-$3.20/gal (up 10-15%), and LIHEAP plus state heat-pump rebates can offset $300-$1,000 of cost for qualifying households.
How much will heating oil cost per gallon this winter?
The EIA Short-Term Energy Outlook for winter 2026-27 projects heating oil at $4.20-$4.80 per gallon average for October 2026 through March 2027, up from $3.95/gal last winter. Three drivers explain the 20-30% YoY rise: (1) the Saudi East-West pipeline attack on September 12, 2026 has tightened global oil supply and added a $5-$15/barrel risk premium to crude; (2) the broader Iran-US tanker war since March 2026 has constrained Gulf shipping and added 10-15 cents per gallon to wholesale diesel and heating-oil costs; (3) the seasonal shift from summer gasoline to winter heating-oil demand typically adds another 15-25 cents per gallon (EIA STEO, September 2026).
Heating oil price forecast by month
| Month | Forecast $/gal | vs last winter |
|---|---|---|
| October 2026 | $4.10-$4.50 | +15-25% |
| November 2026 | $4.20-$4.60 | +18-28% |
| December 2026 | $4.30-$4.80 | +22-32% |
| January 2027 | $4.40-$4.90 | +22-35% |
| February 2027 | $4.20-$4.70 | +18-28% |
| March 2027 | $4.10-$4.50 | +12-20% |
| Winter average | $4.20-$4.80 | +20-30% |

Upside risk: the Saudi pipeline shock
If the Saudi East-West pipeline stays shut through Q4 2026, heating oil could spike to $5.50-$6.00 per gallon — 30-50% above the base case. The pipeline had been moving 4-5 million barrels per day (4-5% of global supply) since the Strait of Hormuz closure six months ago. A restart within 4 weeks brings prices back to the EIA forecast; a prolonged outage pushes prices into the upside scenario (Reuters, September 13, 2026).
How much will heating bills cost this winter?
The average US household heating-oil bill for winter 2026-2027 will be roughly $2,000-$2,400, up from $1,650 last winter — a 20-45% increase. Bills vary sharply by region, home size, insulation, and thermostat settings. The table below breaks out the typical household bill by US Census region (EIA STEO, September 2026).
| Region | Avg winter bill | Last winter | Change |
|---|---|---|---|
| Northeast (MA, CT, RI, ME, NH, VT, NY, PA, NJ) | $3,500-$4,500 | $2,800-$3,500 | +$700-$1,000 |
| Mid-Atlantic (DE, MD, DC) | $2,200-$2,800 | $1,800-$2,200 | +$400-$600 |
| Upper Midwest (MI, WI, MN) | $1,800-$2,400 | $1,500-$1,900 | +$300-$500 |
| National average | $2,000-$2,400 | $1,650 | +$350-$750 |

Which households are hit hardest?
Three groups face the steepest hit this winter. (1) Lower-income Northeast households: at projected prices, winter heating can run 8-12% of monthly income during January-March, often forcing trade-offs with food, healthcare, or other essentials. (2) Older homes with poor insulation: pre-1980 homes use 30-50% more heating oil than post-2000 homes of the same size. (3) Households on fixed delivery schedules: prices typically peak in January, so customers who locked in pre-season contracts at $3.80-$4.00/gal in August are now sitting on the cheapest oil in the market (EIA STEO, September 2026).
How can households lower heating bills this winter?
Five moves can cut heating bills 10-30%, totaling $200-$700 in winter savings for the typical Northeast household. Sorted by cost-effectiveness (cheapest wins first):
| Move | Upfront cost | Annual savings | Payback |
|---|---|---|---|
| Programmable thermostat | $30-$50 | $150-$250 | <3 months |
| Furnace tune-up | $80-$150 | $100-$200 | <1 year |
| Window/door sealing | $50-$200 (DIY) | $100-$300 | <1 year |
| Attic insulation (R-60) | $1,500-$4,000 | $300-$600 | 3-7 years |
| Cold-climate heat pump | $5,000-$15,000 | $800-$2,000 | 5-10 years |

Federal and state aid programs
LIHEAP — the Low-Income Home Energy Assistance Program — provides $300-$1,000 per household for the heating season if your household income is at or below 150% of the federal poverty line. The federal LIHEAP budget for FY2026 is $4.1B, historically assisting about 5.5 million households. With higher heating costs this winter, the same budget will help fewer households or provide smaller per-household grants — expect a FY2027 supplemental appropriation request in November 2026. Apply through your state's LIHEAP office; most states open applications October 1 (DOE, September 2026).
State-level heat-pump rebates layered on top of LIHEAP can cut conversion costs by $3,000-$10,000. Mass Save (Massachusetts), NYSERDA (New York), Efficiency Maine, and similar programs in CT, RI, and VT are likely to see record application volumes for the upcoming heating season (DOE, September 2026).
What does the Saudi pipeline shutdown mean for heating oil?
The Saudi East-West pipeline shutdown on September 12, 2026 is the single biggest upside risk to the heating-oil forecast. The pipeline had been carrying 4-5 million barrels per day (4-5% of global supply) since the Iran war closed the Strait of Hormuz in March 2026. Three scenarios bracket the winter outlook:
| Scenario | Pipeline status | Q4 heating oil | Winter avg |
|---|---|---|---|
| Base case | Restart within 4 weeks | $4.30-$4.80 | $4.20-$4.50 |
| Bull case | Restart within 2 weeks + Hormuz reopens | $3.80-$4.20 | $3.95-$4.30 |
| Bear case | Pipeline stays shut through Q4 | $5.20-$5.80 | $5.50-$6.00 |
Source: EIA STEO September 2026; Reuters pipeline-coverage analysis, September 13, 2026.
What to watch
Three signals tell you which scenario is playing out: (1) Saudi Aramco statement on the Sumed pipeline bypass timeline (the Egypt-Red Sea alternate route can carry 2-3 million barrels per day once redirected, taking 2-3 weeks); (2) any diplomatic resolution of the Iran-US tanker war, especially the September 14 Oman meeting outcome; (3) weekly EIA retail heating-oil surveys, which begin publishing regional prices every Monday in October. A Hormuz reopening would cut heating-oil prices by 20-30 cents per gallon by February 2027 (EIA STEO, Reuters, September 2026).
Propane vs. heating oil vs. natural gas: which is cheapest?
Propane is forecast at $2.80-$3.20 per gallon for winter 2026-2027, up 10-15% from $2.65 last winter. Propane is used for home heating in about 4 million US households, primarily in the Midwest and rural areas. The propane increase is smaller than heating oil because propane is more diversified across refineries, natural-gas processing, and imports. Households on propane will see winter bills of $1,200-$1,800, up from $1,000-$1,500 last winter (EIA STEO, September 2026).
| Fuel | Winter 2026-27 price | Typical winter bill | YoY change |
|---|---|---|---|
| Heating oil (Northeast) | $4.20-$4.80/gal | $3,500-$4,500 | +20-30% |
| Propane (Midwest) | $2.80-$3.20/gal | $1,200-$1,800 | +10-15% |
| Natural gas (national avg) | +8-15% rate increase | $700-$1,200 | +8-15% |
| Electric heat pump | Rate +6-10% | $500-$900 | +6-10% |

Should households switch to a heat pump?
A cold-climate heat pump costs $5,000-$15,000 upfront but reduces winter heating costs by 30-50% in mild climates and 50-70% in moderate climates. For a Northeast household currently spending $3,800 on heating oil, that means $1,100-$2,700 in annual savings, paying back the upfront cost in 5-10 years. The federal Inflation Reduction Act heat-pump rebate ($8,000 for low-income households, $2,000 for middle-income) plus state programs (Mass Save up to $10,000, NYSERDA up to $8,000, Efficiency Maine up to $8,000) make the conversion financially attractive for many Northeast households. Expect a 15-20% increase in heat-pump installations across the Northeast in 2027 vs 2026 (DOE, September 2026).
What to do this month
Three actions before October 1: (1) book a furnace tune-up ($80-$150) if you have not already; (2) apply for LIHEAP through your state office if your household income is at or below 150% of the federal poverty line — applications open October 1 in most states; (3) if you are considering a heat pump, request quotes from two local HVAC contractors now — installation slots in Q4 2026 are already filling up. Pre-season oil-buy programs (lock in a delivery in August at last-winter prices) are closed, but October deliveries typically run 10-20 cents cheaper than January peak (EIA STEO, DOE, September 2026).
