We are a family-owned and operated, full-service heating and cooling company headquartered in Marlborough, CT — and we're proud to be Connecticut's largest retail propane facility.
Connecticut Propane & Petroleum was built on a simple belief: homeowners and businesses deserve reliable propane service at honest, competitive prices — without the runaround from big national companies.
We're a family-owned and operated company based right here in Marlborough, CT. With our impressive fleet and our bulk storage facility, you can feel secure that we will always keep you full and content.
We provide the best pricing at the highest standards — whether you're a homeowner switching from oil, a builder needing tanks for new construction, or a business running a commercial fleet.
With 300,000 gallons of on-site propane storage at our Marlborough, CT headquarters, Connecticut Propane & Petroleum is now the largest retail propane facility in the state — giving us the scale to offer better pricing and the security to always have supply when you need it.
Three principles guide everything we do at Connecticut Propane & Petroleum.
Propane isn't a nice-to-have — it heats your home, your water, and your business. We take that responsibility seriously. Automatic delivery customers never have to worry about running low. And when something goes wrong, we're there 24/7.
We believe competitive pricing should be the norm, not a special deal you have to negotiate. Our size and on-site storage give us buying power — and we pass those savings directly to our customers. It's that simple.
We live and work in Connecticut. When you call us, you reach our team — not a national call center. Our drivers know the roads, our technicians know the equipment, and our office staff know your account. That's what local means to us.
Connecticut Propane & Petroleum is a full-service heating and cooling company. That means we don't just fill your tank and leave — we handle furnaces, boilers, hot water heaters, air conditioning, gas fireplaces, pool heaters, generators, and more.
For Connecticut builders and developers, we're a trusted partner for new construction propane installations. We work directly with your contractor, pull permits, and time our installation to fit your build schedule.

"We had a service technician come out to service our fireplace for the winter. He was very thorough, cleaned everything, changed the batteries, cleaned up after himself and really took pride in his work. He was able to answer all my questions. Love working with CT Propane."
"I was looking for a new propane delivery service. I talked to many companies. I chose Connecticut Propane & Petroleum because of the help in providing information and the accessibility of their team. They gave me the confidence to make my decision."
"We needed a gas line added to our existing backup generator to supply a gas range. The techs from CPP did a great job and the cost was less than we expected. A good all-around experience."
