Our Businesses

Whether we’re replacing a pipe, installing a meter or helping a customer grow their business, we bring warmth and confidence to all we do.

When you step into the shower, the water is hot. When you fire up the grill in your restaurant, you cook the perfect meal every time.

We rely on natural gas to live our lives to the fullest and run our businesses efficiently. At Spire, we pride ourselves on always being there for you, so you can focus on what matters most.

That’s true whether you are in Missouri, Mississippi or Alabama, in your home or at work, and now, even in your natural gas-powered vehicle. And no matter where you are, you can count on the same high level of service and responsiveness to your every need. Our dedication to safety and service are at the core of every Spire business.
