National Baseline & Scope Drivers
Replacing a main service panel, typically going from 100A to 200A, including service coordination. National planning range for this job sits between $1,800 and $9,000.
Key Price Drivers for Electrical Panel Upgrade
- Service size and whether the meter moves: Replacing a panel in place is far cheaper than relocating the service point, which requires new service entrance conductors and utility coordination.
- Overhead versus underground service: Underground service upgrades require trenching and sometimes a new conduit run from the transformer, which can double the job.
- Code upgrades triggered by the work: Grounding electrode system updates, AFCI and GFCI protection on replaced circuits, and surge protection are commonly required when the panel is replaced.
- Aluminum branch wiring or knob-and-tube: Legacy wiring found during the upgrade must often be addressed, and remediation can exceed the panel cost itself.
- Utility scheduling: The power company must disconnect and reconnect the service. That appointment drives the schedule and occasionally carries its own fee.
