How much does it cost to upgrade a breaker box safely?

Upgrading a breaker box safely is priced by scope—panel size, service capacity, code corrections, and permitting—with the exact cost confirmed after an on-site inspection. The most common driver is whether your home needs a capacity increase to support EV charging or other new loads. A licensed electrician should calculate your load, assess the service, and handle permits and inspections; our team does this routinely with local inspectors in the Weston area. Planning for future circuits during the upgrade can prevent paying twice later. Financing is available, and qualifying projects may pair with rebate assistance.

Typical cost drivers our electricians check:

• Panel amperage (100A vs 200A+), space count, and brand-specific breaker pricing
• Service entrance/meter upgrades, mast/conduit, and utility coordination
• Relocation, new feeders, or copper-to-aluminum terminations and labeling
• AFCI/GFCI requirements, whole-home surge protection, and grounding/bonding
• Code corrections, trenching for detached buildings, and permit/inspection fees

For a precise quote and a safe, code-compliant plan, book an in-home assessment so we can verify loads and existing wiring.
