Electricity in Charleston is provided by Dominion Energy. You can establish your account online or by calling. We recommend setting this up at least three business days before you move in. A helpful local feature to ask about is the Electric Weather Normalization Adjustment (eWNA); this program helps smooth out those inevitable spikes in your bill during the high-humidity summer months, making your cooling costs much more predictable.

Natural Gas

Natural Gas Providers in Charleston

Natural gas is also managed by Dominion Energy but is handled as a separate service from your electricity. Because many of Charleston’s beautiful historic homes rely on gas for heating and water heaters, it’s best to schedule your start date at least a week in advance. Make sure an adult is home on move-in day so a technician can safely relight your pilot lights and give your appliances a quick safety check.

What to Expect in Charleston

Internet in Charleston is a high-speed showdown between AT&T Fiber, Xfinity, and the local favorite Home Telecom (which is especially big on Daniel Island). Given the “Silicon Harbor” tech boom, you can find speeds up to 5 Gbps in many areas. Just a heads-up: if you’re moving into a historic downtown property, installation can take a bit longer as technicians navigate century-old walls.

Frequently Asked Questions

Why does the water taste "Earthy" sometimes?

In the spring and fall, you might notice a slight musty flavor in your tap water. This is a harmless local quirk caused by seasonal algae blooms in the Bushy Park Reservoir. It’s perfectly safe, but keeping a chilled pitcher in the fridge makes it much less noticeable.

What’s the "Paper Bag Rule" for yard waste?

Charleston is strict here: they will not pick up leaves or grass clippings in plastic bags. You have to use the large brown paper recyclable bags. Also, never rake leaves into the street; they’ll clog the storm drains and turn the next afternoon rainstorm into a private lake on your block.

How do "King Tides" affect my trash?

We occasionally get “sunny day flooding” from exceptionally high tides. If a King Tide hits on your trash morning, the trucks might be delayed because they can’t get through flooded streets. Check the Tide Alerts so you know when to keep your bins on higher ground so they don’t float away.

Will the BAR let me put an AC unit outside?

If you’re in the Historic District, the Board of Architectural Review (BAR) has a say in your exterior. You can’t just slap a satellite dish or a modern AC condenser anywhere visible from the street. You might need a Certificate of Appropriateness before your utility tech starts drilling.

What’s with the yellow barricades on clear days?

If you see barricades and the sun is out, a high tide is likely pushing water into the streets. Don’t drive through it! The saltwater is brutal on your car’s undercarriage, and the wake from your tires can push water right into the crawlspaces of historic homes.

Can I save money on watering my lawn?

Since sewer fees are tied to water use, a big garden gets pricey. A classic Charleston move is to install a separate irrigation meter. It costs a bit more upfront, but the water going to your lawn won’t be charged sewer fees, which saves a fortune during the hot summer months.
