How much does it cost to upgrade from 100 amp to 200 amp service?

Upgrading from 100 amp to 200 amp service does not have a one-size price. A Berkeys electrician will confirm pricing after an on-site load calculation and inspection. Factors that change cost include:

• Panel and meter upgrade needs, grounding, and surge protection.
• Service mast, wire length, and any relocation work.
• Permit, inspection, and any Oncor coordination. Most panel upgrades take 4 to 8 hours. We handle permits and inspections. Select equipment may qualify for our lifetime parts and labor warranty with annual licensed maintenance. <br/>
