How much does it cost to replace a fuse box professionally?

Professional fuse box replacement typically costs $2,500–$7,000 when upgrading to a modern breaker panel. Most of the price comes from the service-upgrade scope, with our electricians handling permits and inspections as part of the project. If your home still uses fuses, replacement is commonly chosen to improve safety, capacity, and code compliance. In older homes, stepping up to 200-amp service is often the biggest cost driver, not the panel hardware itself. We regularly complete these upgrades across the Northborough area and coordinate local inspections to keep the process smooth.

Cost can vary based on:

• Service size (e.g., 100A to 200A) and any meter/main service work
• Panel relocation or bringing grounding and bonding up to code
• Added circuits for EV chargers, heat pumps, or generators
• Existing wiring condition plus permit and inspection fees

If you smell burning or feel heat at the panel, treat it as an emergency and shut power off if safe.
