No. In Longmont these are two different providers. Your natural gas is Xcel Energy at every sampled address, while your electricity, at nearly all addresses, is Longmont Electric Utility. Because Colorado has no retail choice, you can't consolidate them by picking one seller. The setup is determined by your address. Plan on dealing with each provider on its own, and use the lookup first to confirm exactly who covers your home.
Water service comes from Longmont Water, and sewer is run by the City of Longmont, the municipal government itself, at every sampled address. Sewer being a city operation means it's tied to living inside Longmont's limits. A home just past the boundary can sit on a different setup entirely. Before you move, put your address through the lookup so you know which utilities actually reach that specific lot instead of assuming.
Across the Longmont addresses we checked, City of Longmont covers about 80% for electric.
