A 200-amp panel upgrade is not a single, interchangeable package. The final scope depends on the existing service, utility connection, equipment location, grounding and bonding, permit requirements, and necessary finish repairs.
What changes the price?
Major cost factors include overhead versus underground service, meter and main configuration, conductor length, panel location, grounding-electrode work, working space, stucco or wall repair, surge protection, and the local permitting process.
Why an on-site evaluation matters
Two similar homes can require very different work. A proper evaluation identifies the existing service rating, equipment condition, calculated load, utility requirements, access, and whether the upgrade supports EV charging, solar, remodeling, or future equipment.
What a professional proposal should explain
A clear proposal should identify the service rating, major equipment, permit responsibility, utility coordination, grounding work, included repairs, exclusions, and warranty. Comparing only the total price can hide meaningful differences in scope.
