How much does main electrical panel installation typically cost?

Main electrical panel installation with Castle Electric typically costs $1,500 to $3,500, depending on your home’s capacity needs and existing conditions. Most homeowners fall near the middle when moving from 100 amps to 200 amps, and costs rise as the project scope grows. Final pricing is confirmed after an on-site inspection. Our electricians often find that corrosion at the meter or service mast can influence cost more than the panel box itself. We handle permits and inspections as part of a complete, code-compliant upgrade. We regularly complete these projects for homeowners in and around Taunton with predictable, transparent steps.

Costs tend to increase when any of the following are needed:

• 100A to 200A service upgrade with new service conductors
• Meter socket or exterior service replacement due to damage or corrosion
• Subpanel addition or whole-home surge protection
• Grounding and bonding corrections or service-entrance repairs

Ask about $350 off a 200-amp service upgrade. For the safest estimate, schedule an in-person assessment before planning new appliances or circuits.
