Some homes need more power coming in before they can run a fast EV charger, a heat pump and an induction cooktop at the same time. A three phase upgrade adds that capacity.
A common sign
“The electrician said our house doesn’t have enough power for everything we want.”
About three phase power upgrades
Most homes have single phase power. Three phase power brings in more capacity, which can be needed for a fast EV charger, large air conditioning or several high power appliances running together.
The upgrade involves your electricity network as well as an electrician, and not every home needs it. A good electrician will check your actual load and tell you honestly whether it’s worth doing.

Power trips when big appliances run at once
Ask whether you really need three phase, or whether careful load management could do the job. It depends on what you plan to run.

Not sure where to start?
Don’t waste money on upgrades you don’t need. A professional home energy assessment shows where your house loses heat and power, so your budget goes where it makes the biggest difference.

More in EV charging
Charge overnight, or straight off your own roof. Licensed electricians who do the supply and the wiring, not just the box on the wall.

A wall charger and the circuit to run it. Overnight on a home charger is the cheapest way to fill a car.

A charger that follows what the roof is making, so the car fills on your own power rather than the grid.
