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

The cost to upgrade electrical service to 200 amps is confirmed only after an on-site inspection because scope can range from a panel replacement to a full “heavy up” of the incoming service. The biggest price driver is whether your home needs new service equipment in addition to the breaker panel.

Our electricians regularly complete 200‑amp heavy‑ups in the Dorchester area. When upgrading, the National Electrical Code requires a Type 2 surge protection device at the panel, and it will be needed to pass the city inspection. If you only need a few new circuits, reorganizing the panel or adding a subpanel may meet your needs at a lower cost. We also offer a $25 Electrical Panel Check to diagnose your panel and outline options.

What most affects price:

• New breaker panel vs. restoring an existing panel
• Service entrance components (meter socket, mast, or service cable)
• Grounding and bonding updates to meet current code
• Added circuits, AFCI/GFCI protection, or generator/EV charger coordination

Schedule a panel check so a licensed electrician can verify load size and provide a firm, written estimate. <br/> Updated: 2026-03-29 <br/> Need help in Dorchester, MA? Call (978) 716-5703 or book online.
