Electrical Panel & Service Upgrades in London, Ontario

A 100A to 200A service upgrade in London typically costs $2,400 to $3,500 + HST, includes the ESA permit and inspection, and takes about one working day. Levere Electric does a load calculation first, so you only upgrade if your home actually needs it.

When a panel or service upgrade makes sense

• You are adding a Level 2 EV charger, hot tub, or heat pump and the load calculation shows the service is at its limit
• The panel is full and there is no room for new circuits
• Breakers trip regularly, or you hear buzzing or crackling at the panel
• The panel is an older or recalled model, or has visible heat damage
• A renovation or addition is adding significant new load

Not every EV charger needs a bigger service. Many 100A homes can run a 40A charger safely once the numbers are checked. If the load calculation says you are fine, we will tell you.

How it works

1. Send a photo of your panel and a note about what you are adding. Use the request form or call 226-559-7897.
2. We run the load calculation and send a written quote with the options, including whether an upgrade can be avoided.
3. We coordinate the utility disconnect, replace the panel and service equipment, and bring grounding and bonding up to code.
4. ESA inspects the work. You get a labelled panel and the permit paperwork.
