400 Amp Service Upgrade in Victoria, BC

Grifflyn electrician completing a 400 amp service upgrade on a large Victoria home

A 400 amp service upgrade in Victoria gives larger homes the electrical capacity to run everything at once without tripping or overheating. This is the high-capacity tier, built for homes with suites or shops, multiple EV chargers, or a heat pump plus a hot tub plus a sauna all drawing at the same time. It is a bigger job than a standard 100A or 200A upgrade, and it has to be coordinated with BC Hydro and done to code. To talk through your home, call Grifflyn Electric at (778) 350-2677.

Most Victoria homes run fine on 200A. You are likely looking at 400A if you recognize a few of these:


When do you need a 400 amp service?

  • Your panel is full and you have no room to add circuits for new loads.

  • You are adding two or more EV chargers, or a charger plus other heavy loads.

  • You are electrifying the home: heat pump, induction range, hot tub, and sauna together.

  • The property has a secondary suite or a detached shop that needs its own service.

  • The home is large or custom built, with high simultaneous demand across the house.

  • An electrician has done a load calculation and your existing service cannot support the planned total.

  • You plan on running large machinery that draws a lot of power.


Why upgrade to 400 amp, and why it has to be done right.

  • Larger Bear Mountain and custom homes often carry loads that exceed what a 200A service can safely deliver.

  • Suites and detached shops add demand that a single standard service was never sized for.

  • Electrifying an older Victoria home stacks heat pump, EV, and appliance loads onto wiring that predates them.

  • A 400A upgrade involves a new meter base, service equipment, and often mast or trenching work, so it is more than a panel swap.

  • It requires coordination with BC Hydro for the larger service, plus an electrical permit and inspection.

  • Undersized or improperly installed high-amperage service is a severe safety and fire risk, which is why it should be installed by a licensed electrician.


Our 400 amp service upgrade process

Red Seal electrician reviewing a load calculation before a 400 amp upgrade in Victoria
  1. We assess your current service and run a load calculation to confirm 400A is the right size for your home.

  2. We give you upfront pricing based on your specific setup, including overhead versus underground and any mast or trenching work.

  3. We pull the electrical permit and coordinate with BC Hydro for the upgraded service.

  4. We install the new meter base, service equipment, and panel, and complete any mast or trenching required.

  5. BC Hydro reconnects the upgraded service on the coordinated schedule.

  6. The work is inspected and signed off, and we walk you through your new setup before we leave.


WHAT’S THE Cost of a 400 amp service upgrade in Victoria

A 400 amp service upgrade usually starts around $20,000 depending on the circumstances. The final figure depends on whether the service is overhead or underground, the meter base and service equipment, any mast or trenching work, and BC Hydro's requirements for your property. Because these vary so much, we treat it as a starting-from figure and give you an exact price after an on-site assessment. See our upfront pricing for how we quote larger jobs.
