We are a family-owned and operated, full-service heating and cooling company serving all of Connecticut — and we're proud to operate the largest retail propane operation in the state.
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 proudly based in Connecticut. With our impressive fleet and our bulk storage facilities across the state, 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 600,000 gallons of on-site propane storage across our Waterbury, Oxford, and Marlborough facilities — and a new facility coming soon in Griswold — Connecticut Propane & Petroleum is the largest retail propane operation 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.
See All ServicesFrom day one, CPP has invested in the technology that keeps Connecticut families warm and worry-free. We were the first propane company in the region to install remote tank monitors on customer tanks — giving us real-time visibility into fuel levels so we can schedule deliveries before you ever get close to empty. No more guessing, no more run-outs.
That same forward-thinking approach has earned us recognition across the industry — read Cargas' feature on CPP's growth and operations →
As we continue to grow across Connecticut, our commitment stays the same: invest in the tools and technology that make propane delivery smarter, safer, and more reliable for every customer we serve.
What started as a single family-owned propane company in Marlborough has grown into one of the largest retail propane operations in the state — built one community at a time.
Connecticut Propane & Petroleum got its start in Marlborough, CT — delivering reliable propane and honest pricing to local families and businesses.
One of our earliest acquisitions, RFI Propane brought new delivery routes, assets, and loyal customers into the CPP family — laying the groundwork for the growth that followed.
Through the acquisition of Phoenix Propane, we expanded to a second location in Oxford, CT — adding storage capacity and welcoming new customers into the CPP family.
By acquiring Purple Fuel's propane routes and customers, we grew our presence into the Guilford area — welcoming new families with the same reliable delivery and service they'd come to expect.
Through the acquisition of Best Propane, we opened a major storage facility in Waterbury, CT, welcoming thousands of new customers and helping make CPP one of the largest retail propane operations in the state.
Our story continues — we're opening a brand-new facility in Griswold, CT, bringing CPP's reliable service and competitive pricing to Eastern Connecticut.
We are consistently looking to build trusted partnerships. If you are an independent fuel or propane business owner in New England considering your next steps, we invite you to reach out to discuss alignment opportunities.
