Upgrading an electrical panel to 200 amps typically costs $1,500 to $6,500, including permits and code compliance. Pricing varies most with the panel’s condition, labor and material needs, scope of code updates, and any service equipment work outside the panel. Most projects take 6–10 hours and are usually completed in one day with power off during the work. We provide flat-rate pricing after an on-site assessment, and our licensed electricians handle permitting and inspections across the Denver metro, including Thornton. In many homes, the meter base or service mast drives cost more than the panel hardware itself.
Key factors that can raise or lower the total:
- Meter base/service mast replacement or utility coordination
- Panel relocation or repairs to feeders/grounding
- AFCI/GFCI breaker upgrades or whole-home surge protection
- Adding EV charger or other dedicated circuits during the upgrade
For an exact 200-amp quote, schedule an in-home evaluation so we can verify loads, grounding, and utility requirements.
