How to lower your gas bill in 2026
Start with the statement before changing your thermostat or buying new equipment. A higher gas bill can come from more usage, more billing days, a different rate, delivery charges, meter corrections or a combination of several changes.
Review My Bill1. Compare usage, billing days and the unit rate
Put the current bill next to the previous one. Compare total gas usage, the number of days in each billing cycle, the meter-reading dates and the price charged per unit of gas. A longer billing cycle can increase the total even when daily use is similar.
If the increase appeared suddenly, start with our high gas bill checklist. For a broader utility review, see why a utility bill may be high.
2. Calculate daily gas use
Divide billed usage by the number of billing days. Comparing daily use gives you a cleaner picture than comparing totals from unequal billing cycles. If daily usage rose sharply, weather, thermostat settings, heating-system performance, hot-water demand or a building-envelope problem may be contributing.
If daily use stayed close to the previous period but the dollar total rose, focus more closely on the unit price, delivery charges and fixed fees.
3. Separate supply from delivery and fixed charges
Gas bills often include more than the gas itself. Depending on the utility and state, the statement may separate supply, delivery, distribution, customer or service charges. Some components vary with consumption while others do not.
Our gas delivery charge guide explains why lowering consumption may not reduce every line item by the same percentage. For unfamiliar items, use the utility bill charge guide.
4. Use thermostat setbacks when they fit your household
The U.S. Department of Energy says households can save as much as about 10% on heating by turning the thermostat back 7°F to 10°F from its normal setting for eight hours a day, when that strategy is appropriate for the heating system and household. A programmable or smart thermostat can make scheduled setbacks easier.
Department of Energy heating-saving guidance provides additional examples.
5. Look for drafts and air leakage
Heating a home is harder when warm air escapes through gaps around doors, windows, attic penetrations and other openings. Department of Energy guidance identifies air sealing and insulation as common ways to reduce wasted heating and cooling energy.
Before spending heavily, look for obvious drafts, worn weatherstripping and accessible gaps. Larger air-sealing projects or combustion-safety concerns are better evaluated by an appropriate professional.

6. Check ducts and heating equipment
If your home uses forced-air heating, leaky or poorly connected ducts can waste conditioned air before it reaches the rooms. ENERGY STAR says a typical home can lose roughly 20% to 30% of the air moving through its duct system because of leaks, holes and poor connections.
Replace or clean filters according to equipment instructions, keep vents unobstructed and have persistent performance problems evaluated. If the furnace is cycling abnormally, struggling to heat rooms or producing unusual odors or sounds, treat that as an equipment issue rather than simply turning the thermostat higher.

7. Do not forget gas water heating
If your water heater uses natural gas, hot-water demand is part of the bill too. More showers, hotter settings or a change in household occupancy can increase gas use even when space-heating habits did not change much. Review the water-heater setting and maintenance requirements for your specific equipment before making adjustments.
8. Check estimated or corrected meter readings
An estimated reading can be followed by a catch-up adjustment when the utility later records actual usage. Compare the meter-reading type and meter values shown on consecutive bills. If a correction created a large balance, ask the provider to explain the adjustment and available payment options.
See our estimated meter reading guide for a step-by-step comparison.
