Going all-electric? Tick what you're planning and see whether your supply and switchboard can carry it — and what to do first so you can stage the rest at your own pace.
Get the foundations right, then stage the rest
Going all-electric is almost always a staged project — induction now, a heat pump when the old system dies, an EV charger when the car arrives. What ties it together is the supply and the switchboard: they're the foundation everything else sits on. Getting a realistic number early, with the maximum demand calculator, tells you whether you can add loads freely or need to plan an upgrade first.
The EV charger is usually the load that tips the balance — check it on its own with the EV charger readiness checker. If the numbers point to three-phase, our guide on how to upgrade to three-phase walks through what's involved.
Frequently asked questions
Do I need to do everything at once to go all-electric?
No — most homes electrify in stages over several years as appliances reach end of life. The key is to get the foundations right early: the supply and switchboard. If those have headroom, you can add induction, a heat pump, reverse-cycle and an EV charger in whatever order suits your budget.
Which electrification step uses the most power?
An EV charger is typically the biggest single load — a common 7 kW charger draws around 32A on its own dedicated circuit. Reverse-cycle heating/cooling is next. Induction cooking, heat pump hot water and a pool heat pump are more modest, but they add up, which is why a demand assessment is worth doing before you commit.
Will I need three-phase power to electrify my home?
Not always. Many homes electrify fully on an upgraded single-phase supply. Three-phase becomes attractive when you're combining an EV charger with reverse-cycle and other big loads, or planning fast EV charging. It's a Level 2 ASP job involving new consumer mains, metering and a network application.
Can I keep my old switchboard as I add appliances?
Only if it has spare ways and modern protection. Many older boards are full or still use rewireable fuses, and each electrification step generally needs its own RCBO-protected circuit. Upgrading the switchboard early is usually cheaper and cleaner than doing it piecemeal under time pressure.
