Three-Phase Power Upgrade — Sydney Level 2 Electrician

Book or quote your job

Licensed Level 2 ASP · 24/7 across Sydney · Fixed-price quotes

Upgrading from single-phase to three-phase power gives your home or business the capacity to run high-demand equipment — fast EV chargers, ducted air conditioning, pool and spa heating, workshop machinery and large all-electric homes — without overloading the supply or tripping out. A three-phase upgrade is Level 2 ASP work: it means new consumer mains, a three-phase switchboard and metering, and coordination with the Ausgrid network. Sydney Electrical Service is a licensed Ausgrid Level 2 ASP (licence 236351C). We assess, connect and certify three-phase upgrades across Sydney — and lodge the Certificate of Compliance on completion. Available 24/7.

What's Involved

A three-phase upgrade is more than swapping a switchboard — it's an end-to-end Level 2 job:

Load assessment — confirming what you're running (EV charger, ducted air-con, pool, workshop) and the capacity you need.
Confirming three-phase is available at your street and coordinating the supply with Ausgrid.
New consumer mains — upgrading the overhead or underground mains to three-phase, sized correctly.
Three-phase switchboard — a new board with a three-phase main switch, RCDs and clearly labelled circuits.
Three-phase metering — coordinating the meter with your retailer's provider.
Network disconnection and reconnection, handled by us as a Level 2 ASP.

It's commonly done alongside a switchboard upgrade or a consumer mains upgrade.

NSW Compliance

Upgrading the supply to three-phase — the consumer mains, metering and network connection — is Level 2 Accredited Service Provider (ASP) work. Sydney Electrical Service is an accredited Ausgrid Level 2 ASP (licence 236351C). Mains sizing, the switchboard and connection meet AS/NZS 3000 and Ausgrid's service and installation rules, and we lodge a Certificate of Compliance for Electrical Work (CCEW) on completion.

Pricing Approach

We quote three-phase upgrades as a fixed price after a load assessment and confirming three-phase availability at your street, whether the mains are overhead or underground, and the switchboard and metering scope. Call 0433 462 902 for a fixed-price quote.

Sydney-Specific Considerations

Most older Sydney homes were built single-phase, and demand for three-phase is climbing as households add fast EV charging, ducted air-con and go all-electric. Three-phase isn't available at every street, so we confirm availability with Ausgrid before quoting — and coordinate the upgrade across Sydney's mix of overhead and underground supply.

Frequently Asked Questions

Why would I upgrade to three-phase power?

Three-phase gives you much more capacity — it's the usual upgrade for fast (22kW) EV chargers, ducted air conditioning, pool/spa heating, workshops and large all-electric homes that overload a single-phase supply.

Is a three-phase upgrade Level 2 work?

Yes. It involves new consumer mains, three-phase metering and a network connection, which are Level 2 Accredited Service Provider work. We're an accredited Ausgrid Level 2 ASP.

Is three-phase available at my place?

Not at every street — it depends on the network in your area. We confirm three-phase availability with Ausgrid before we quote, so you know up front.

Do I need a new switchboard as well?

Usually yes — a three-phase supply needs a three-phase main switch and board. We often do the switchboard upgrade and the three-phase mains together as one job.

How much does a three-phase upgrade cost?

It depends on the mains run (overhead or underground), the board and metering, and street availability. We assess the load and give a fixed-price quote — call 0433 462 902.

Will the power be off during the upgrade?

Only while we disconnect to install the new mains, board and metering. As a Level 2 ASP we handle the disconnection and reconnection to keep the outage as short as possible.
