TL;DR: The cheapest heating oil in Southern Maine changes daily and isn’t always the same dealer twice. The fastest way to find today’s lowest price is to compare current dealer prices on our live board, then confirm the all-in cost — minimum gallons, fees, and payment terms — before you order.

Calling around for heating oil quotes is a part-time job nobody asked for. By the time you’ve reached the fifth dealer, the first one’s price has already moved. This post shows you how to find the genuinely cheapest price in York County today — and how to make sure “cheapest per gallon” is actually cheapest out the door.
Instead of dialing dealer by dealer, start where the numbers already sit side by side. Our Southern Maine price board shows the visible prices for the dealers we track — including Desrochers Oil, CN Brown Energy, Ace Oil Maine, Heatwave Oil LLC, and Welch Oil — so you can spot the low number in seconds.
Two honesty notes: the prices are observed snapshots from when we last checked, and when a dealer hasn’t posted a current price we show an empty state rather than a guess. So you’re comparing real numbers, not filler.
The lowest advertised price can still cost you more once the full order is tallied. Before you commit, check these four things with the dealer:
We cover the plan-and-fee trade-offs in depth in COD vs. Automatic vs. Fixed Price.
A price spread that looks small per gallon adds up fast:
That’s the whole reason to compare every time — the savings on one fill can cover dinner out, and over a winter it’s real money.
If your tank isn’t critically low, a little patience helps. Prices tend to ease in the off-season and climb during cold-weather demand spikes. Watch the direction of the market on our weekly Southern Maine price trend before you pull the trigger. If you’re running low in a cold snap, though, don’t gamble — a timely fill at today’s price beats an emergency run-out.
The biggest way people lose the savings they just found is by running the tank too low while waiting for a better price, then getting caught by a cold snap and paying a premium for an emergency same-day fill — sometimes with a restart fee if the system runs dry. Cheap oil you can’t wait for isn’t cheap. If your tank has a comfortable cushion, shopping the board patiently pays off. If you’re near the bottom, lock in today’s best price and worry about optimizing next time. Saving 40 cents a gallon means nothing if a run-out costs you a service call and a tank of premium-priced emergency oil.
Not every dealer delivers to every town in York County, and the cheapest dealer overall isn’t always the cheapest one that reaches your address. We track a growing set of Southern Maine dealers and are building out town-level pages so you can compare only the companies that actually serve your area. Where coverage isn’t confirmed, we say so rather than guess — so you never call a dealer who can’t reach you. For now, the live board shows everyone we track across Southern Maine and the Seacoast.

Who has the cheapest heating oil in Southern Maine right now?
It changes daily, so there’s no permanent answer. Check the live board for today’s lowest visible price among the dealers we track, then confirm with the dealer before ordering.
Why do heating oil prices differ so much between dealers?
Dealers pay different wholesale costs and set different margins, minimums, and fees. That’s why comparing — and confirming the all-in price — beats loyalty to one company. Our pillar guide explains the full pricing mechanism.
Is the cheapest advertised price always the best deal?
Not always. A low per-gallon price can come with a high minimum, added fees, or cash-only terms. Compare the total cost of the delivery, not just the headline number.
How much can I actually save by comparing?
A common 30–60¢ spread means roughly $45–$90 on a 150-gallon fill. Comparing each time you order is the simplest way to keep that money.
Are the prices on your board guaranteed?
No — they’re visible snapshots that change frequently. Always confirm the current price and terms with the dealer before placing your order.
