How much does it cost to upgrade electrical service to 200 amps?

Upgrading electrical service to 200 amps is priced after an on‑site assessment because total cost depends on your current panel, service entrance, and required code/permit work. Most projects are driven by an outdated or undersized panel that can’t safely handle modern loads. Our licensed electricians handle permits and code‑compliant 200‑amp upgrades throughout the Denver area, including many homes in Thornton. On older homes, the service lateral and meter can be the swing cost; a clean panel swap isn’t the same as a full service upgrade. For high‑risk FPE or Zinsco panels, full replacement is recommended rather than in‑panel repairs. Free estimates and financing options are available.

You’ll get the most accurate price once these are checked on site:

• Panel replacement vs full service upgrade (mast/meter/service wire)
• Grounding/bonding updates and surge protection choices
• Panel relocation or new circuits for EV/hot tub loads
• Utility coordination, permit fees, and required AFCI/GFCI breakers

Schedule a load assessment before adding big appliances so the quote reflects your actual power needs.
