Is it worth upgrading from 100 amp to 200 amp service?

Upgrading from 100A to 200A service is often worth it for most Ottawa homes, especially if you're planning to add an EV charger, heat pump, or other high-demand appliances. The investment typically pays off in increased home value, electrical safety, and future-proofing your property.

When 200A Service Makes Sense

A 100A panel was adequate for homes built 20-30 years ago, but today's electrical demands have grown significantly. If you're frequently tripping breakers, planning to install an EV charger (which typically requires a dedicated 40A circuit), or adding major appliances like a hot tub, heat pump, or electric vehicle, your 100A service is likely maxed out. Modern homes also use more electronics, LED lighting systems, and smart home devices that collectively increase your electrical load.

In Ottawa's market, homes with 200A service are increasingly expected by buyers, especially in neighborhoods with higher-end properties. The upgrade demonstrates that your electrical system can handle modern demands safely and legally according to Ontario Electrical Safety Code requirements.

Cost vs. Value in Ottawa

A 100A to 200A upgrade in Ottawa typically costs between $2,000 - $3,500, including the ESA permit and inspection. This includes upgrading the main panel, meter base, and often the service entrance cable. If your current panel is an older Federal Pacific or Zinsco brand, the upgrade becomes even more valuable since these panels are known fire hazards that insurance companies increasingly refuse to cover.

The upgrade usually adds $3,000 - $5,000 to your home's value, making it a smart investment even before considering the practical benefits. You'll also avoid the higher costs of trying to work around a maxed-out 100A system when installing new appliances or circuits.

ESA Requirements and Safety

Any service upgrade requires an ESA permit and inspection, which ensures the work meets current Ontario Electrical Safety Code standards. This includes proper grounding, bonding, and arc fault protection that older 100A panels may lack. The inspection process typically takes 3-5 business days after completion, and you'll receive a Certificate of Inspection that's valuable for insurance and resale purposes.

Signs You Need the Upgrade

If you're experiencing frequent breaker trips, dimming lights when appliances start, or your electrician has told you there's no capacity for additional circuits, the upgrade is necessary rather than optional. Planning to install an EV charger, electric heat pump, or finishing a basement with additional outlets also makes 200A service essential.
