Long Island Propane Price FAQs
What is the current propane price on Long Island?
NYSERDA's latest posted Long Island residential propane benchmark is $4.339 per gallon for July 2026. Long Island in that survey combines Nassau and Suffolk counties, and individual dealer quotes can differ.

No. Delivery quantity, annual usage, tank ownership, automatic versus will-call service, route location, payment terms and account fees can all change a household quote.
Can Suffolk County homeowners compare propane quotes here?
Yes. SuffolkPropaneRates.com focuses on Suffolk County and matches quote requests privately using the homeowner's ZIP code, tank details and service needs.
Why does this page discuss Nassau if the site focuses on Suffolk?
Because NYSERDA publishes Long Island propane benchmark data as a combined Nassau-and-Suffolk region. We explain that limitation rather than presenting the regional average as a Suffolk-only dealer quote.
