Upgrading to Three-Phase Power: What Happens to Your Meter?

A three-phase upgrade isn’t just bigger cables — your meter has to be exchanged for a three-phase unit, and that’s Level 2 work.

The Problem: Single-Phase Running Out of Headroom

Ducted air conditioning, an EV charger, a pool, a home workshop — modern loads add up fast, and a single-phase supply has a hard ceiling. Symptoms include tripping mains, lights dipping when big appliances start, and installers telling you their equipment needs three-phase before they’ll quote.

The upgrade itself touches the parts of the installation homeowners can’t: the service connection, consumer mains and the meter, all of which sit in Level 2 territory.

The Solution: A Coordinated Three-Phase Upgrade

A proper three-phase upgrade covers the network application, new consumer mains, a switchboard capable of three-phase distribution, and a three-phase smart meter to replace the single-phase unit. Doing these as one coordinated job avoids the classic stall where the wiring is upgraded but the meter exchange is stuck in a retailer queue.

Smart Meter Australia handles the full scope — Level 2 service work, board upgrade and the three-phase metering — across Ausgrid, Endeavour Energy and Essential Energy areas.

The Result: Capacity for Everything at Once

With three phases and the right meter, the EV charges, the ducted system runs and the workshop hums simultaneously — with load spread across phases and accurate interval data on each.

COMMON QUESTIONS

Does three-phase cost more to run?

No — you pay for the energy you use, same as single-phase. Three-phase is about capacity, not a different price for electricity.

Can I keep my existing smart meter?

A single-phase meter can’t measure a three-phase supply, so the meter is exchanged for a three-phase smart meter as part of the upgrade.
