The cost to upgrade an electrical panel in Charleston ranges from $680 to $2,550, with most homeowners paying around $1,280. Your actual cost depends on several factors specific to your home and the Charleston market.
Jumping from 100A to 200A costs significantly more than a simple panel swap at the same amperage due to heavier wiring and meter base changes.
Panels in tight closets, basements, or exterior walls may require additional labor to access and meet modern clearance codes.
Old aluminum wiring or cloth-insulated wire may need replacement to safely connect to a new panel, increasing scope.
Some jurisdictions require whole-house AFCI/GFCI protection or grounding upgrades when replacing a panel, adding circuits and cost.
The utility must disconnect and reconnect power — scheduling and any required meter base upgrades add time and potential fees.
The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
Budget $41–$410 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
In cold climates, expect additional costs for heated conduit runs, insulated wire, and work scheduling around freezing temperatures. Winter installations may cost 10–15% more due to shorter workdays and weather delays.
This project requires a licensed professional in Charleston. Attempting electrical panel upgrade without proper licensing can void insurance and create serious safety hazards.
