The cost to upgrade an electrical panel in St. Louis ranges from $760 to $2,840, with most homeowners paying around $1,420. Your actual cost depends on several factors specific to your home and the St. Louis market.
Jumping from 100A to 200A costs significantly more than a simple panel swap at the same amperage due to heavier wiring and meter base changes.
Panels in tight closets, basements, or exterior walls may require additional labor to access and meet modern clearance codes.
Old aluminum wiring or cloth-insulated wire may need replacement to safely connect to a new panel, increasing scope.
Some jurisdictions require whole-house AFCI/GFCI protection or grounding upgrades when replacing a panel, adding circuits and cost.
The utility must disconnect and reconnect power — scheduling and any required meter base upgrades add time and potential fees.
The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.
