Utility Costs in New Hampshire vs Maine vs Massachusetts (Real Numbers)

Utility Costs in New Hampshire vs Maine vs Utility bills deserve a place in your homebuying budget alongside the mortgage, property taxes, and insurance. Across New Hampshire, Maine, and Massachusetts, energy prices differ, but the home itself can have an even bigger effect on what you spend.

There is no single cheapest state for every utility. In the data reviewed for this comparison, New Hampshire had the lowest electricity price, Massachusetts had the lowest propane price, and Maine and New Hampshire had nearly identical heating oil prices.

This guide compares New England utility costs using published residential energy prices and clearly labeled calculations. It also explains how to evaluate water, sewer, internet, and the actual utility history of a property.

As a REALTOR® serving New Hampshire, Maine, and Northern Massachusetts, I help buyers evaluate the ownership costs that affect whether a home fits their budget. My approach is to pair public energy data with property records, seller-provided bills, and appropriate inspections, rather than assume a statewide average predicts an individual home’s expenses.

What do the real utility cost numbers measure?

The figures below use three distinct reporting periods:

Electricity: July 2026 residential prices, published September 24, 2026.
Heating oil and propane: Residential prices for October 5, 2026, published October 7, 2026.
Natural gas: Calendar-year 2024 residential prices, providing a common annual comparison because the reviewed table does not report a 2025 Maine figure.

These are statewide benchmarks, not quotes from a particular supplier.

The calculated examples hold consumption constant to show price differences. They are not measured average household bills or forecasts.

How much does electricity cost in New Hampshire vs Maine vs Massachusetts?

July 2026 residential electricity prices were 26.60 cents per kilowatt-hour in New Hampshire, 32.41 cents in Maine, and 30.49 cents in Massachusetts.

A kilowatt-hour, or kWh, measures electricity consumption. A 1,000-watt appliance operating for one hour uses approximately 1 kWh.

State	Residential price per kWh	Calculated cost at 600 kWh	Calculated cost at 1,000 kWh
New Hampshire	$0.2660	$159.60	$266.00
Maine	$0.3241	$194.46	$324.10
Massachusetts	$0.3049	$182.94	$304.90

At 600 kWh, the calculated Maine cost is $34.86 higher than New Hampshire’s. Massachusetts is $23.34 higher.

These preliminary statewide prices reflect reported residential revenue per kWh, rather than a supply-only offer. Multiplying them by usage creates a comparison benchmark, not an exact utility bill. Your tariff, fixed charges, supplier, discounts, and consumption affect the result.

Do not multiply a July example by 12 and treat it as a reliable annual forecast. Prices and household usage change throughout the year.

How much does heating oil cost in New Hampshire, Maine, and Massachusetts?

For October 5, 2026, published residential heating oil prices were approximately $5.98 per gallon in New Hampshire and Maine, compared with $6.12 in Massachusetts.

The following calculations retain the published three-decimal prices. Prices exclude taxes.

State	Heating oil price per gallon	Calculated 150-gallon delivery	Calculated cost of 600 gallons
New Hampshire	$5.976	$896.40	$3,585.60
Maine	$5.974	$896.10	$3,584.40
Massachusetts	$6.119	$917.85	$3,671.40

The 600-gallon example is an assumed quantity, not average annual consumption. It also assumes every gallon costs the survey price, which will not necessarily hold across a heating season.

At equal consumption, the difference between Maine and Massachusetts is $87 for 600 gallons. By comparison, using an additional 200 gallons at $5.974 would cost $1,194.80.

That illustrates why insulation, air leakage, thermostat settings, and heating equipment can matter more than a modest difference in state fuel prices.

Actual delivery quotes may vary with location, order size, payment method, service agreements, and purchase timing.

How much does propane cost in New Hampshire vs Maine vs Massachusetts?

For the same October 5, 2026 reporting date, Massachusetts had the lowest residential propane price of these three states.

State	Propane price per gallon	Calculated cost of 100 gallons	Calculated cost of 600 gallons
New Hampshire	$3.953	$395.30	$2,371.80
Maine	$3.546	$354.60	$2,127.60
Massachusetts	$3.594	$359.40	$2,156.40

Correction to the ranking: Maine, at $3.546 per gallon, had the lowest propane price in this survey, followed by Massachusetts and New Hampshire.

The calculated difference between New Hampshire and Maine is $244.20 at 600 gallons.

As with heating oil, this is an equal-volume illustration, not a household average or seasonal forecast. Published prices exclude taxes.

Before buying a propane-heated home, verify tank ownership, supplier restrictions, rental charges, minimum purchases, and the pricing category that would apply to your expected use.

Do not compare oil and propane solely by price per gallon. They contain different amounts of energy, and heating system efficiency affects how much useful heat reaches the home.

How do natural gas costs compare across the three states?

Using the same calendar year for all three states, 2024 residential natural gas prices were:

State	Price per thousand cubic feet	Calculated cost at 50 thousand cubic feet
New Hampshire	$18.74	$937.00
Maine	$18.95	$947.50
Massachusetts	$21.90	$1,095.00

Mcf means one thousand cubic feet of natural gas. Some household bills use therms, which measure energy content. Those units require conversion before comparing prices.

The 50-Mcf example is an assumed annual quantity. These historical statewide prices are not current utility tariffs or predictions for your home.

For a gas-heated property, obtain recent bills and confirm the current supply, delivery, and customer charges. Also verify service availability at the address rather than assuming natural gas is available throughout a community.

Are heat pumps cheaper to run in New Hampshire, Maine, or Massachusetts?

A heat pump’s operating cost depends on electricity prices, equipment performance, weather, and the home’s heating demand.

A heat pump moves heat rather than producing all of it directly through electric resistance. Its coefficient of performance, or COP, compares useful heat output with electricity input.

For illustration, a system delivering 3,000 kWh of heat at an average COP of 3 would consume approximately 1,000 kWh of electricity. Electric resistance heating would require roughly 3,000 kWh to provide that amount of heat.

This does not establish a particular home’s savings. Heat pump performance changes with outdoor temperature, installation, operating settings, and backup heating.

For a property with heat pumps, review:

Equipment model and installation date.
Cold-weather capacity and performance.
Which rooms the system serves.
Backup heating type and usage.
Electricity bills and any remaining fuel deliveries.

A home may use heat pumps for part of its heating while retaining oil, propane, or gas. Review both energy sources to understand the full cost.

How much should buyers budget for water, sewer, and internet?

These expenses require address-specific information. A single state average would conceal important differences among providers and service arrangements.

How do water and sewer costs affect a home’s utility budget?

Public water and sewer charges may include fixed fees, usage charges, and other assessments. Confirm the billing frequency before comparing amounts.

For example, a hypothetical $240 quarterly bill equals $80 per month for budgeting purposes.

A private well eliminates a public water bill but can involve pumping electricity, testing, treatment, and repairs. A septic system requires maintenance and may eventually need significant repairs or replacement.

For either arrangement, review recent records and the condition of the equipment.

How should buyers compare internet costs?

Check service at the exact address and obtain the regular price after promotional discounts expire.

Include equipment fees, installation, contract terms, and the service level your household needs.

A hypothetical $75 monthly plan costs $900 annually before additional fees. This is a budgeting example, not a statewide internet average.

How can you estimate total utility costs before buying a home?

Start with at least 12 months of property-specific records. When available, two years can help reveal seasonal patterns and unusual periods.

Request:

Electricity bills showing dollars and kWh.
Natural gas bills showing usage and charges.
Oil or propane delivery records.
Water and sewer bills.
Internet service availability and regular pricing.
Heating equipment and service records.
Information about utilities included in association fees.

For delivered fuels, purchases may differ from consumption if the tank began and ended the period at different levels. A vacant property or a seller who uses supplemental wood heat can also produce records that do not represent your expected household use.

Calculate an annual total, then divide by 12 to create a monthly reserve. Keep enough flexibility for winter bills and changing prices.

Avoid double counting: If electricity already powers the home’s heating, its electric bill includes that consumption. If association fees include heat or water, account for those costs within the fee.

Which matters more for New England utility costs: the state or the home?

State prices provide context. The property determines how much energy and service your household needs.

Consider heated square footage, insulation, air sealing, windows, heating efficiency, cooling, hot water, and occupancy.

A hypothetical home using 500 gallons of oil at $6 per gallon costs $3,000 to fuel. A less efficient home using 800 gallons at $5.75 costs $4,600.

The second home has a lower fuel price but a higher fuel expense. That is why comparing homes requires both price per unit and units consumed.

What are the frequently asked questions about utility costs in New Hampshire, Maine, and Massachusetts?

Which state has the cheapest utilities?

There is no universal winner. New Hampshire had the lowest electricity price in the July 2026 comparison. Maine had the lowest oil and propane prices in the October 5 survey, although Maine and New Hampshire oil prices were nearly identical.

What is the average monthly utility bill in these states?

The tables here do not measure total average household utility bills. They show published energy prices and equal-usage calculations. A useful estimate for a particular home requires its usage history and current provider rates.

Are Maine utility costs always higher than New Hampshire’s?

No. Maine’s electricity price was higher in the reviewed month, while its oil and propane prices were lower on the reviewed survey date.

Is a home with a private well and septic system cheaper?

Not necessarily. It may avoid recurring municipal bills, but testing, maintenance, equipment repairs, and eventual replacement still belong in the ownership budget.

Can I use a seller’s utility bills to predict my expenses?

Use them as evidence, not a guarantee. Adjust for occupancy, thermostat settings, vacancy, supplemental heat, weather, and changes in utility prices.

What should I request before making a utility budget?

Request a full year of bills and fuel deliveries, usage quantities, equipment information, current rates, and details about services included in association fees.

How can you compare utility costs when choosing your next home?

The most useful comparison combines published prices with the home’s actual consumption, equipment, and service arrangements.
