Everything Auckland homeowners need to know before installing an EV charger at home.

Charging at home is cheaper and far more convenient than relying on public chargers — you wake up to a full battery every morning. But a home EV charger needs to be installed properly and safely. Here’s what to know.

Why charge at home?

Home charging uses your household power, which is cheaper than most public fast-chargers — especially on off-peak rates. It’s also convenient: plug in overnight and you’re ready to go.

What affects the installation

The main consideration is your switchboard and supply capacity. Adding a fast charger is a significant load, so we check whether your home can handle it and whether smart load management is needed.

Switchboard capacity

Older boards may need an upgrade.

Charger location

Distance from the board affects cabling.

Smart charging

Schedule for cheap off-peak power.

Load management

Balances the charger with your home's load.

Choosing a charger

Most home chargers are 7kW single-phase units, which fully charge most EVs overnight. Smart chargers add scheduling and app control. We can supply and install, or install a unit you’ve already bought — and we’ll advise honestly on what suits your car and home.

Getting it installed

We check your switchboard, plan the neatest and safest cable run, install and certify the charger, and walk you through using it before we leave. The result is tidy, safe and future-ready.
