Project guide
What the work includes, what changes the price, and what to ask.
A panel upgrade replaces your main service equipment so the home can carry more load safely. The work usually includes a new panel and breakers, grounding and bonding updates, a utility coordination step and an inspection. Estimt produces a preliminary planning range and routes the project to electricians serving your ZIP code.

AI estimates are preliminary planning ranges, not binding contractor quotes. Actual costs may change after professional inspection based on project scope, materials, permits, access, local requirements, and hidden conditions.
Service size
Going from 100A to 200A or 400A changes equipment and utility work.
Panel location
Relocating the panel adds conduit, wiring and patching.
Utility coordination
Disconnect and reconnect scheduling can affect timeline and cost.
Existing wiring
Aluminium branch wiring or old grounding often needs remediation.
Permit and inspection
Panel work is permitted and inspected in nearly every jurisdiction.
