Three Phase Power Upgrades on the Northern Beaches
Need more power than single phase can deliver? As ASP accredited Level 2 electricians, we upgrade Northern Beaches homes and businesses from single to three phase, handling the supply side from the network through to your switchboard.













Three Phase Power for Growing Electrical Demand
As homes and businesses continue adding air conditioning, EV chargers, workshops, commercial equipment, and other high-demand appliances, a standard single phase supply may no longer be enough. Upgrading to three phase provides greater capacity, improved load distribution, and a more reliable electrical supply, while preparing your property for future expansion.
When Is a Three Phase Upgrade Needed?
Three phase power isn't necessary for every property, but it's often the best solution when electrical demand continues to grow.
Common reasons to upgrade include:
- Installing ducted air conditioning
- Fast EV charging
- Home workshops and machinery
- Commercial equipment
- Pool heating and large electrical loads
- Future-proofing your property
Upgrading your supply now helps avoid capacity issues and reduces the likelihood of future electrical upgrades.
Three Phase Upgrade Services We Provide
We manage every aspect of the upgrade process, including:
- Single to three phase service upgrades

One Team Managing the Entire Upgrade

Our ASP accredited Level 2 electricians coordinate the complete project, giving you one experienced team managing every step safely, efficiently, and backed by our lifetime labour warranty.

When Do You Need Three Phase Power?
Three phase isn't needed for every home, but certain setups really benefit from it. Here are the most common reasons people upgrade.
Ducted Air Conditioning
Large ducted and multi-head air conditioning systems often need three phase to run efficiently without overloading a single phase supply.
EV Charging
Faster home EV chargers and multiple chargers can draw more than single phase can comfortably handle, making three phase the better setup.
Workshops & Machinery
Home workshops, sheds, and commercial equipment frequently require three phase to power motors and heavy machinery.
Pools, Spas & High Demand
Pool heating, spas, and homes simply adding a lot of load at once often outgrow single phase and run better on three phase.

Why Choose Us for Your Three Phase Upgrade
A three phase upgrade is a significant change to your electrical supply, and the supply side has to be done by an accredited Level 2 electrician. Here is what you get when you choose us:
- ASP accredited Level 2 — authorised to upgrade the service connection and mains from single to three phase on the Ausgrid network.
- End to end — we handle the supply, metering, and switchboard side and coordinate the whole upgrade so nothing is left hanging.
- Future-proofed — we size the upgrade for the load you're planning, so it serves you for years to come.
- Lifetime labour warranty — every upgrade is backed by our lifetime labour guarantee.
Done properly, coordinated for you
The trickiest part of a three phase upgrade is the coordination between the network, the metering, and your switchboard. Get one part out of sync and the job stalls. We manage all of it, so you deal with one accredited local and we take care of the distributor and the technical side. A three phase upgrade is often done alongside a consumer mains or switchboard upgrade, since they work together to handle your new supply safely, and we can assess and quote the whole job at once. Every part is completed to AS/NZS 3000 and distributor requirements, with all compliance certificates provided on completion.
