How much does it cost to upgrade electrical service to 200 amps?

Upgrading electrical service to 200 amps varies in cost because it depends on the condition of your current service and which components must be replaced or added. The biggest driver is whether you need a full service and panel replacement or mainly panel and breaker upgrades. Panels past about 30 years often warrant replacement, and modern protection (AFCI/GFCI breakers) plus a whole‑home surge suppressor are standard parts of a safe, code‑aware upgrade. Our licensed electricians have installed hundreds of services across Southeastern Idaho, so we scope what’s needed instead of guessing. If the existing panel is sound and capacity is adequate, repair or targeted additions may suffice; if it’s undersized or shows heat damage, replacement is the safer path.

Typical cost factors we evaluate on site:

• Panel replacement vs. repair and main breaker sizing
• Number of new circuits and AFCI/GFCI breaker upgrades
• Whole‑home surge suppressor and related code‑required protection
• EV charger, generator, or transfer switch additions
