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

Upgrading electrical service to 200 amps is quoted after an on-site evaluation because total cost depends on your existing service and the scope of work. The biggest driver is whether the main panel and related service equipment must be replaced to meet current electrical code and your home’s load needs. Our electricians routinely perform 200‑amp upgrades in the Marysville area and can advise if you truly need a full service change. In some homes, a subpanel or load management can delay a full upgrade without sacrificing safety.

If you’re comparing estimates, look for these cost drivers:

• Main panel, meter base, mast, and service conductors replacement scope
• Feeder length and any panel relocation or rerouting
• Grounding/bonding updates and modern protections (AFCI/GFCI, surge protection)
• Added circuits or subpanels for heat pumps, EVs, hot tubs, or generators/transfer switches

Schedule an on-site evaluation to receive a firm quote and confirm whether a full 200‑amp upgrade or a targeted solution fits your home. <br/> Updated: 2026-03-09 <br/> Need help in Marysville, WA? Call (425) 259-0550 or book online.
