Propane Prices in Suffolk County, NY: What Homeowners Are Paying

Updated September 8, 2026

There is no single propane price that applies to every Suffolk County homeowner. The best public benchmark comes from NYSERDA, but a real delivered quote can move based on tank ownership, annual gallons, delivery size, route location and service terms.

Pricing source note: Public benchmark references come from NYSERDA's New York Home Propane Price Monitoring Program. Long Island combines Nassau and Suffolk. Benchmarks are informational and are not guaranteed dealer quotes.

Latest Long Island propane benchmark

NYSERDA's latest surveyed Long Island residential propane benchmark is $4.339 per gallon for July 2026. Long Island combines Nassau and Suffolk counties, and NYSERDA notes that its full-service residential credit-price accounts typically use about 1,100 gallons or more per year. It is a regional benchmark, not a guaranteed quote for a specific home.

For context, the July 2026 benchmark of $4.339 per gallon is lower than the February 2026 Long Island monthly average of $4.627, showing how much propane pricing can move during the year.

How to compare quotes fairly

Ask each provider to quote the same scenario: the same tank ownership, approximate gallons, delivery timing and service plan. A lower first-fill price is not necessarily the lowest long-term account cost.

SuffolkPropaneRates.com asks for account details before matching a request so providers can respond to the actual household instead of a generic countywide average.

Where our pricing information comes from

We use NYSERDA's New York Home Propane Price Monitoring Program as the primary public Long Island benchmark. We also use U.S. Energy Information Administration propane data as a broader market reference. We do not present either source as a live dealer quote.

Frequently Asked Questions

What is the current average propane price on Long Island?

NYSERDA's latest posted Long Island residential benchmark is $4.339 per gallon for July 2026. Nassau and Suffolk are combined in that region, and actual household quotes can differ.

Is $4.339 the price I will pay in Suffolk County?

Not necessarily. It is a regional survey benchmark, not a guaranteed quote. Delivery size, annual usage, tank ownership, route location and service terms can all change the delivered price.

Why do smaller propane users sometimes pay more per gallon?

A small or infrequent account can cost more to service per gallon than a high-volume routed account because the delivery truck, driver and stop have fixed operating costs.
