How much does it cost to upgrade from 100 amp to 200 amp service?
Most 100 amp to 200 amp service upgrades fall in the $1,500–$3,500 range in Norwood-area homes. Larger or more complex projects can run $2,000–$10,000 based on panel type, meter/service work, grounding, and home layout. We handle permits, inspections, labeling, and final testing. Free consultations include a written quote and action plan. Financing and limited-time promotions (e.g., $350 off a 200-amp upgrade) are available.
Quick check:
- Share photos of your panel and meter for faster pricing.
- Ask about EV/heat pump readiness.
