How much does it cost to upgrade from 100 amp to 200 amp service?

Costs for a 100A-to-200A service upgrade vary by home. A technician must inspect your panel, service mast, meter base, grounding, and space needs before confirming a price. We offer a free panel upgrade consultation, $150 off new electrical panel installation, and financing options. Eligible projects may qualify for a federal tax credit of 30% up to $600. We handle permitting and code compliance as needed, and provide 20-year panel warranties plus lifetime workmanship coverage in the Atlanta area, including Roswell and Alpharetta.
