Close to the hospital and medical precinct, Westmead properties often double as home offices and consulting spaces, which adds load the original single phase wiring was never built for. We're Level 2 ASP electricians upgrading Westmead homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Westmead
Westmead homes (2145) are increasingly outgrowing the single phase supply they were built with, a pattern that shows up locally through medical precinct home office. Between ducted air conditioning, induction cooking, EV charging and a home office running at once, a single phase 60 to 100 amp service starts to show its age through tripping mains, dim lighting and motors that wear out faster than they should.
Upgrading to three phase power gives a Westmead property the capacity for both family living and a professional home office. Load is spread evenly across three conductors instead of one, voltage stays stable, and you unlock equipment single phase cannot support, medical or office equipment, ducted air conditioning, an EV charger, all running together.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Endeavour Energy network that supplies Westmead, so the whole upgrade is handled by one team from quote to energised.


Why Westmead Properties Are Upgrading to Three Phase
Westmead sits within Western Sydney, served by the City of Parramatta Council. These are the upgrade triggers we see most often in 2145:
- Home offices and consulting rooms near the Westmead medical and health precinct.
- Renovations and extensions on established Westmead homes.
- Granny flats and secondary dwellings on established blocks.
- EV ownership, with home chargers increasingly common close to the precinct.
- Ducted air conditioning replacing older split systems.
- Older switchboards that need replacing alongside the phase upgrade.

Reliable capacity
Give every high draw appliance in the house its own clean supply so nothing browns out when the rest of the home is running hard.
Future-proof for EVs & solar
Means the next EV charger, solar upgrade or home battery goes in without the supply becoming the limiting factor.
Longer appliance life
Motors, compressors and control boards run cooler and last longer when they are not fighting voltage dips.
Lower running costs
Three phase equipment simply runs leaner, which flows through to a lower power bill.
Property value
Three phase supply is a documented selling point buyers and agents look for when a Westmead property goes to market.
Compliance peace of mind
Certificate of Compliance, Level 2 ASP certification and correctly approved metering handled as part of the job.
Do I Need A Power Upgrade?
You should consider upgrading if you:
- Install multiple high-power appliances or industrial equipment.
- Are renovating or constructing a new building that will have increased energy requirements.
- Require adherence to the latest safety standards and electrical codes, which may mandate more robust systems.

What is a Three Phase Power Upgrade?
Single phase power uses one live wire and typically provides up to 240 volts, adequate for light loads but not optimal for heavier consumption without risking system overload and inefficiency. In contrast, a three phase power system incorporates three alternating currents, equally spaced in phase angle, providing up to 415 volts. This configuration allows for a more consistent delivery of power, as the total power delivered never drops to zero, a distinct advantage particularly in industrial settings or in homes with high energy demands.

FAQs
Can I get a three phase upgrade done on a rented or tenanted property?
Yes, we regularly work with landlords and property managers in Westmead. We coordinate timing with tenants and provide all compliance paperwork the agency needs on file.
How much does a single to three phase upgrade cost in 2145?
Costs depend on switchboard scope, mains length, point of attachment changes and Endeavour Energy network requirements. We provide a detailed fixed quote after a free on site assessment, so there are no surprises mid job.
Will I lose power during the upgrade?
Yes, briefly. We coordinate the changeover to minimise disruption, typically a few hours on the day of energisation. We give you advance notice so you can plan around fridges, work from home setups and any pool or aquarium equipment.
Is a three phase upgrade disruptive to neighbours?
Most of the work happens inside your switchboard and meter box. If overhead network changes are required on your street, Endeavour Energy schedules that separately and notifies affected neighbours directly.
Are you authorised to work on the Endeavour Energy network in Westmead?
Yes. High Demand Electrical is a Level 2 ASP under Licence 397193C, authorised to disconnect, upgrade and reconnect directly to the Endeavour Energy network throughout Western Sydney.
