How Much Does an Electrical Panel Upgrade Cost?

A standard residential panel upgrade from 100 amp to 200 amp service often costs $1,800 to $3,500 installed in a straightforward swap where the existing wiring and meter setup cooperate. That range usually includes the new panel, breakers, labor, permit, and inspection. Smaller jobs cost less. Replacing a damaged 200 amp panel without upgrading service entrance wire may run $1,200 to $2,000 if the feed and meter are already adequate. More complex upgrades can exceed $4,000 and reach $6,000 or higher. Long service entrance wire runs, underground feed replacement, meter base upgrades, trenching, or bringing an older home fully up to current code all add substantial labor and materials. Adding a subpanel for a garage, ADU, or workshop is a related but separate project. A subpanel install commonly runs $500 to $1,500 depending on distance from the main panel and circuit count.

Service amperage and condition of the entrance cable are major factors. Upgrading the panel alone is cheaper than replacing the wire from the meter to the panel when the old feed is undersized or deteriorated. Utility coordination affects timeline and sometimes cost. Your electrician works with the local utility for meter pulls and reconnections. Some regions require utility-side work that appears as a separate line on your bill. Code requirements add components. Modern installs often need arc-fault and ground-fault breakers on certain circuits, proper grounding and bonding, and labeled circuits. Older homes may need new grounding electrodes or water pipe bonding updates. Wall and finish repair can follow if the new panel is larger than the old cutout or if conduit routes change. Most electricians handle basic patching; extensive drywall work may involve another trade. Permit and inspection fees vary by municipality. They are usually a few hundred dollars combined and should be included in a complete quote.

Frequent breaker trips, buzzing from the panel, warm breakers, corrosion, or a panel brand with a known safety history are clear reasons to upgrade. Insurance and home sale inspections also flag undersized 60 or 100 amp services that cannot support modern loads. Moving to 200 amps gives headroom for central AC, induction cooking, tankless water heaters, and future EV charging without juggling circuits. It does not automatically lower your electric bill, but it reduces fire risk from overloaded circuits and makes later additions cheaper to wire. A panel upgrade is also the right time to fix double-tapped breakers, missing neutrals, and abandoned circuits buried in walls. A reputable electrician documents what they find and quotes corrections beyond the swap itself.

Request an on-site evaluation rather than a phone estimate. Photos help, but the pro needs to see your meter, panel brand, available space, and whether the service entrance wire is aluminum or copper. Ask what the quote includes: panel and breakers, permit, inspection, utility reconnect, grounding updates, and any trenching or meter base work. Clarify whether finish patching around the panel is included. Get the scope in writing before work starts. Panel upgrades are not a good place for surprise add-ons. If the electrician finds unsafe wiring inside the panel, you want that discussed before breakers are moved over, not after the power is out.
