Wilcox Energy History

We just celebrated another year, and we couldn’t have done it without you! Since 1955, Wilcox Energy has been serving residences along the CT shoreline and lower CT River Valley.

A lot has changed in the almost 70 years since our founding. Through the evolution of time, we have added propane delivery and service, HVAC installation, & ductless heat pump installations. Heating oil has evolved too. We now deliver a cleaner, greener Bioheat® blend of renewable fuel.

Throughout all the decades, one thing has remained certain: Wilcox Energy has always been built on the promise of offering quality, reliable service 24 hours a day, 7 days a week. Check out our timeline to learn more about our legacy.

Wilcox Energy's Timeline

Wilcox Energy's rich history is a testament to our commitment to providing exceptional energy solutions and service to our community. From our humble beginnings over five decades ago to our position today as a trusted energy provider, we have continuously evolved to meet the changing needs of our customers.


Dick and Don Wilcox start the Wilcox Fuel Company, delivering oil to their customers in 50-gallon drums.


In a victory for feminists everywhere, the Wilcox & Daughters oil trucks rolled through town in response to the numerous "& sons" businesses that were becoming so prominent.


A 2nd floor is added to the Wilcox office building and the main level is completely renovated and remodeled to accomodate the growing needs of the company.


Wilcox Energy incorporated Bioheat® heating oil in our efforts to help reduce carbon emissions. All of our customers receive up to a blend of b20 Bioheat® heating oil.
