Moving into a new home means answering one deceptively simple question: which companies actually supply electricity, natural gas, and water to this address? The answer is not always obvious, because utility service is divided into territories, and the company serving your neighbor across the county line may differ from yours. The reliable path runs through your state's Public Utility Commission, an official regulator whose online tools can tell you exactly who serves your address. This guide walks through that process, using Florida and Ohio as worked examples.

Starting Your Search: Initial Steps for New Residents

Before turning to government websites, start with the people who already know the answer. Moving guides consistently recommend asking your landlord, property manager, or the previous residents for provider recommendations, since they have paid these bills firsthand. Your lease or purchase documents may also name the utilities already connected to the property.

These conversations are the fastest route, but they are a starting point rather than a guarantee. A previous tenant may misremember a company name, and in some areas you may have a choice of suppliers for certain services. That is why the process below escalates from informal sources to an authoritative check, rather than stopping at the first answer you receive.

Understanding Public Utility Commissions (PUCs)

Every U.S. state has a regulatory body—usually called a Public Utility Commission (PUC) or Public Service Commission (PSC)—that oversees the utilities operating within the state. These commissions oversee services including electricity, natural gas, and water and wastewater, and they maintain records of which regulated companies serve which territories. The National Association of Regulatory Utility Commissioners maintains a roster of these state bodies, which includes not only commissions but also agencies like Connecticut's Department of Energy and Environmental Protection and Minnesota's Department of Commerce, reflecting the varied names these regulators carry.

Because commissions license and regulate these utilities, their websites are the most authoritative place to confirm who serves a given location. A federal contact list compiled by the FCC's Internet Services Staff confirms that each state has such an agency; while that list is oriented toward telecommunications regulators, it demonstrates that a named state body exists for every state.
