This is a snapshot of the DCP registry, not a ranked or best-of list. The table shows 30 dealers in alphabetical order out of 88 propane-registered companies; a handful are headquartered just over the line in New York, Rhode Island, or Massachusetts but registered to serve Connecticut addresses. Browse the complete Connecticut directory or enter your ZIP to see the closest dealers. Use it to find a company near your town and to confirm it is on the state registry. Registration is not an endorsement, so still confirm insurance and get three written quotes. For a view based on customer reviews rather than the registry, see the highly-rated shortlist next.

Rated by customers, not the registry

Well-reviewed Connecticut propane dealers, region by region

The registry above is complete but unranked. This is the other half: one hand-checked dealer for each major region, quoted with its real public review score. Connecticut is heating-oil country, so many fuel dealers carry thin or split review bases; two of these land in the 3.5 to 4.0 band rather than at the top, and they are shown that way on purpose. Ratings were read in August 2026 and move over time, so treat a good score as a starting point, confirm DCP registration, and still get three written quotes.

Why Connecticut carries the Northeast's highest propane price

Connecticut runs a cold five-month heating season and sits at the very top of the regional price table. The reasons are structural rather than seasonal: pipeline geography, a heating-oil-first fuel mix, and a natural-gas grid that pushes propane out to the suburbs and hill towns.

Price figures: EIA State Heating Oil and Propane Program (SHOPP) residential survey, full-service delivery. Real Connecticut quotes run roughly 10 to 15% either side of this average depending on supplier, contract type, owned versus rented tank, and how far you are off a dense route.

End of the pipeline. New England has no propane production and sits farthest from Gulf Coast and Appalachian supply. Product moves by rail and pipeline into terminals in New York, New Jersey, and Pennsylvania, then transfers to bobtail trucks for the last-mile run into Connecticut. Every handoff is a margin layer that interior producing states never pay.
Heating-oil country. Connecticut has one of the highest home-heating-oil shares in the country, which leaves propane a smaller, more dispersed customer base. Fewer propane homes per route means thinner delivery density, smaller per-supplier volumes, and weaker economies of scale, all of which lift per-gallon overhead.
Cities on the gas grid. Hartford, New Haven, Bridgeport, and Stamford are served by natural gas, so propane is largely a suburban and rural fuel. The customers who do use it are spread across Litchfield, Windham, and the shoreline back-country, which stretches routes and thins the competitive pressure that holds prices down in denser markets.
Sparse rural competition. Along the I-91 and I-95 corridors several suppliers compete on price. In the northwest hill towns and parts of eastern Connecticut only a few active propane routes reach a given address, so retailers hold margin. That is also where owning your tank and quoting all three supplier tiers pays off most.

Four moves that cut a Connecticut propane bill

A registered dealer is the starting point. In a high-cost market the gap between a careless account and a well-run one is a few hundred dollars a winter, and this is where it is won.

01

Confirm the DCP registration

Any company delivering propane to homes must register as a Home Heating Fuel Dealer with the Department of Consumer Protection and carry an HOD number. Connecticut issues no separate propane-dealer license, so check the DCP registry first, then ask for proof of liability insurance. Storage and handling sit under the state Fire Safety Code enforced by the State Fire Marshal.

02

Lock summer, not autumn

Wholesale bottoms out from June through August. Most Connecticut suppliers run pre-buy or budget-lock enrollment across May to August, and locking summer gallons rather than paying the January spot rate has saved roughly $300 to $500 a year for a 1,000-gallon home. Favour a cap-price contract, which keeps the savings if winter wholesale falls, and ask whether unused gallons roll forward.

03

Quote all three supplier tiers

Connecticut has a real three-tier market: national carriers (AmeriGas, Suburban Propane), regional family fuel dealers with in-state storage (Hocon, East River Energy, Connecticut Propane & Petroleum), and local independents in the hills and the east. Pull one written quote from each tier. If you own your tank, say so up front, because it removes the switching penalty that leased-tank customers face.

04

Check CEAP eligibility

The Connecticut Energy Assistance Program, run by DSS through the Community Action Agencies, pays a winter heating benefit toward propane for households at or below 60% of State Median Income. For 2025-2026, basic benefits run $295 to $595, or $345 to $645 with a vulnerable household member, plus crisis and deliverable-fuel help. Apply by dialing 211, through your Community Action Agency, or at portal.ct.gov/heatinghelp. The 2025-2026 deadline is 29 May 2026.

What a fill actually costs at $4.12/gal

Tanks fill to 80% of stated capacity (the 80% rule) to allow for thermal expansion, so a 500-gallon tank takes about 400 usable gallons. Here is the Connecticut 2026 average worked through the common residential tank sizes, next to what the same fill costs at the national average.

Tank sizeUsable gallons (80%)Fill cost at $4.12/galvs national ($2.67/gal)
100 gal80 gal$329+$115
250 gal200 gal$823+$288
500 gal400 gal$1646+$577
1000 gal800 gal$3293+$1154

A typical Connecticut propane-heat household burning 800 to 1,200 gallons a year spends roughly $3293 to $4939 on fuel alone, before tank rental or service contracts. That is about $1442 more than a comparable 1,000-gallon household in a national-average market. Compare the national refill cost guide or the 500-gallon tank cost breakdown.

Where Connecticut lands among its neighbours

The whole Northeast sits well above the national average, all of it fed by the same end-of-pipeline supply. In the latest EIA reading Connecticut prints the highest state figure in the region, ahead of the New England and Mid-Atlantic states around it. Pennsylvania runs cheapest of the group, closer to Marcellus and Utica supply.

Connecticut propane questions, answered

Where do the dealers in your directory come from?
Every company listed here is drawn from the Connecticut Department of Consumer Protection (DCP) Home Heating Fuel Dealer registry, the state's public record of businesses registered to deliver propane and other heating fuels. Connecticut publishes it as open data, and we captured the propane-registered subset on 23 August 2026, carrying 88 dealers. The HOD number beside each dealer is its DCP registration identifier. Registration is a licensing record, not an endorsement, and current registrations run through 30 September 2027, so still confirm a company's standing and insurance and get written quotes before you sign.
How do I check that a Connecticut propane company is properly registered?
Connecticut does not issue a standalone propane-dealer license. A business that delivers propane to homes must register as a Home Heating Fuel Dealer with the Department of Consumer Protection, and each registration carries an HOD number. Verify a company against the DCP registry (the same open-data list this directory is built from) before you commit. Separately, the trades that install and service propane systems are licensed by DCP, and LP-gas storage and handling fall under the Connecticut Fire Safety Code, enforced by the State Fire Marshal and local fire marshals under NFPA 58. Because there is no single public scorecard for propane dealers, treat DCP registration as the floor, then compare quotes and ask for proof of liability insurance.
Am I eligible for the Connecticut Energy Assistance Program (CEAP)?
CEAP is Connecticut's federally funded winter heating-assistance program, run by the Department of Social Services (DSS) through the state's network of Community Action Agencies. Households at or below 60% of the State Median Income can qualify, and any household where a member receives Temporary Family Assistance, SNAP, or SSI is automatically income-eligible. For the 2025-2026 season, basic benefits run from $295 to $595, or $345 to $645 when a household member is under 6, age 60 or older, or has a disability, with crisis and additional deliverable-fuel help for propane, oil, and kerosene households. Online applications opened on 1 September 2025 and the last day to apply is 29 May 2026. Apply by dialing 211, at your local Community Action Agency, or through portal.ct.gov/heatinghelp, and apply early because deliverable-fuel deliveries slow down at the January and February peak.
Why is Connecticut propane the most expensive in the Northeast?
In the latest EIA reading Connecticut's residential average is $4.12 a gallon, the highest state figure in the Northeast region and about 54% above the $2.67 national average. The drivers are structural. New England is the end of the propane pipeline, with no in-state production and the longest haul from Gulf Coast and Appalachian supply, so propane arrives by rail and truck through New York, New Jersey, and Pennsylvania terminals before the last-mile bobtail run. Connecticut also heats heavily with oil, which leaves propane a minority fuel served on thinner routes, and its cities sit on the natural-gas grid, so propane is largely a suburban and rural fuel with dispersed customers. Add a high-cost energy region and a cold five-month winter and the per-gallon number stays near the top of the national table.
Should I switch from heating oil to propane in Connecticut?
Heating oil dominates Connecticut's residential market, and for many oil-heated homes a switch is not economic on fuel cost alone. A gallon of propane carries about 91,500 BTU against roughly 138,500 for heating oil, so you burn about 1.5 gallons of propane to match one gallon of oil, and propane's lower per-gallon price does not fully close that gap. Propane still wins on cleanliness, on running a gas range, dryer, or standby generator, and on freeing up an indoor tank, but a full conversion of the boiler or furnace plus a tank install is a multi-thousand-dollar project that takes years to pay back at current spreads. The switch makes sense mainly when your oil system is already at end of life or you want propane for cooking, hot water, a generator, or a pool.
Does summer pre-buy actually save money in Connecticut?
Yes, consistently. Connecticut wholesale propane bottoms out from June through August, when refinery output is high and residential demand is near zero, and most CT suppliers run pre-buy or budget-lock enrollment from around May through August. Locking summer gallons rather than paying the January and February spot rate has saved roughly $300 to $500 a year for a 1,000-gallon household in recent seasons. Read the contract before you sign: a cap-price contract lets you keep the savings if winter wholesale falls, a strict pre-buy locks the price in either direction, and you should ask whether unused pre-paid gallons roll into the next season.
How do I switch propane suppliers in Connecticut without losing my tank?
Most Connecticut homeowners lease their tank from their current supplier, which legally limits who can fill it. To switch without buying the tank out, the new supplier arranges a tank swap: they notify the old supplier, pull that tank, and set their own, typically over one to three weeks. If you own your tank outright, any registered supplier can fill it, which is the strongest leverage in this market because it lets you shop every fill on price. Buying a tank from a supplier generally runs from several hundred to a couple of thousand dollars depending on size and install, and it usually pays back through cheaper gallons if you keep the home for the long term.
