Want to compare heating oil prices Long Island NY homeowners actually pay? Right now, retail rates run from $4.07 to $6.01 per gallon depending on your supplier and zip code.

Many Nassau and Suffolk County homeowners pick a supplier once and stick with them for years, never stopping to check whether a better rate is available nearby. This guide walks you through exactly how to find today’s per-gallon rates for your zip code, what to look at beyond the headline price, and how to recognize a genuinely competitive offer when you see one.
For a local reference point, Oil Prices Long Island serves both Nassau and Suffolk County with no-contract, cash-on-delivery heating oil and competitive advertised rates. That kind of straightforward offer gives you a clean reference point as you start comparing suppliers across the Island.
Where to check today’s heating oil prices for your Long Island zip code
Two sources give you the most reliable price benchmarks when you compare heating oil prices Long Island NY style, meaning zip-code specific, not just regional. NYSERDA publishes a monthly Long Island regional average, currently $5.52 per gallon for May 2026 (source: NYSERDA monthly petroleum price report). HeatFleet shows a live retail range of $4.07 to $6.01 per gallon for Long Island as of today (source: HeatFleet live price listings). Keep in mind that NYSERDA’s figure is a monthly average across the entire region, not a real-time supplier quote, use it as a market temperature check rather than a shopping price. For background on how regional averages are calculated and what they mean for consumers, see Understanding the Home Heating Oil Market.
County-wide averages can hide meaningful differences between towns. A homeowner in Huntington and a homeowner in Hempstead may face different rates from the same company on the same day. To get an accurate number, go directly to a supplier site or a live price aggregator like HeatFleet, enter your zip code, and request a quote for a standard delivery. That zip-code specific quote is the number that actually matters when you decide who to call. Tools like a heating oil price tracker NY residents can use, such as HeatFleet, let you monitor daily changes before you commit.
The four factors that determine your real cost per delivery
The advertised per-gallon rate is only the starting point. Delivery minimums vary by company: some suppliers accept orders as low as 50 gallons, while others require 100 gallons or more for residential stops. Some also charge a flat delivery fee on top of the per-gallon rate. The real calculation is simple: gallons ordered multiplied by the price per gallon, plus any delivery fee. A supplier showing a low per-gallon price but requiring a 200-gallon minimum or adding a $25 delivery charge may not be your cheapest option once you do the math.
Payment method can also shift the price. Some companies post a cash price and charge more for credit card orders. Others build that difference into their advertised rate without stating it clearly. Before you put two fuel oil rates Suffolk Nassau suppliers are offering side by side, confirm both quotes are based on the same payment terms.
Contract terms are commonly overlooked and are a frequent source of complaints among Long Island oil customers. Some suppliers lock customers into annual price-cap contracts or budget billing plans that include enrollment fees, service agreement charges, or early termination penalties. A supplier that looks competitive at the headline rate may cost more over the full season once those terms are factored in. No-contract, will-call arrangements give you the freedom to buy when you choose and switch suppliers whenever a better rate appears.
Compare heating oil prices Long Island NY: what a competitive offer looks like
When evaluating any quote, it helps to know what a strong, no-frills offer includes. Oil Prices Long Island covers both Nassau and Suffolk County with competitive per-gallon pricing, no service agreements, and a COD payment model that requires no credit account and no long-term commitment. Use that structure as a reference point: if a competitor’s quote comes with a contract requirement, a minimum order that doesn’t fit your tank size, or fees added at delivery, those are real costs worth calculating before you sign anything.
The three main purchasing structures you’ll encounter during a heating oil price comparison Long Island homeowners typically run into are COD delivery, budget billing plans, and locked fixed-price contracts. COD means you pay at delivery with no ongoing commitment, and your price reflects the market rate on the day you order. Budget billing spreads your annual heating cost into equal monthly payments, which smooths cash flow but doesn’t necessarily protect your per-gallon price. Fixed-price contracts lock in a rate for the season, which helps if prices spike, but they typically come with service fees and limit your flexibility to switch. For most homeowners who want the lowest cost and the ability to shop around, a no-contract COD arrangement is the most flexible option.
How to vet a supplier before your first delivery
Online reviews are useful, but not all signals carry equal weight. Focus on recent review volume, specific mentions of on-time delivery, and recurring complaint patterns. On Long Island, common complaint themes across oil delivery suppliers include billing errors, unclear delivery timing, and contract disputes involving automatic renewals or price disagreements. When those patterns show up repeatedly for the same company, that’s more meaningful than a single bad experience. All Island Fuel, for example, holds a 3.9 out of 5 rating on Google Reviews, with customers noting prompt delivery alongside concerns about pricing consistency. If you encounter unresolved issues, you can file a complaint with the New York State Department of Public Service.
Before placing your first order with any supplier, ask these questions:
- What is the per-gallon rate for my zip code today, and are there any additional delivery fees?
- Do I need to sign a contract, and what are the cancellation terms?
- Do you accept COD, or is a credit account required?
These questions surface the information that separates a genuinely competitive offer from one that looks good until the invoice arrives. For a practical checklist to use when you call suppliers, see Tips for Selecting the Best Home Heating Oil Supplier.
