Fairfield's busy household kitchens, home businesses and established housing stock all add up to demand the original single phase supply was never built for. We're Level 2 ASP electricians upgrading Fairfield homes from single phase to three phase power, safely and compliantly.
Three Phase Power Upgrades Built for Fairfield
Fairfield homes (2165) are increasingly outgrowing the single phase supply they were built with, a pattern that shows up locally through home business and older housing. Modern loads add up fast, ducted air conditioning, induction cooktops, EV chargers, pool equipment and a home office, and a single phase 60 to 100 amp service shows the strain through tripping mains, dim lights and appliances that struggle to perform.
Upgrading to three phase power gives a Fairfield property real capacity. Load is spread evenly across three conductors instead of one, voltage stays stable, and you unlock equipment single phase cannot run, commercial grade kitchen gear, ducted air conditioning, an EV charger, together.
As authorised Level 2 electricians, we're certified to disconnect and reconnect directly to the Endeavour Energy network that supplies Fairfield, so the whole upgrade is handled by one team from quote to energised.


Why Fairfield Properties Are Upgrading to Three Phase
Fairfield sits within South-West Sydney, served by the Fairfield City Council. These are the upgrade triggers we see most often in 2165:
- Home based food businesses and commercial kitchen equipment.
- Older wiring and switchboards in established Fairfield homes.
- Granny flats or secondary dwellings on established blocks.
- Renovations and extensions adding ducted air conditioning.
- EV ownership, with home chargers becoming more common.
- Solar and battery upgrades that perform better on three phase.

Reliable capacity
Handle heavy loads at the same time, ducted air conditioning, a pool pump, an EV charger and the oven, without the mains giving up.
Future-proof for EVs & solar
Gives you the headroom to add a second EV, a bigger battery or a larger solar array whenever you are ready.
Longer appliance life
Spreading the load across three conductors reduces the voltage sag that shortens the life of motors and pumps.
Lower running costs
Efficient three phase equipment and a stable supply add up to a leaner power bill over the year.
Property value
A certified three phase upgrade is a real point of difference when the property is next on the market.
Compliance peace of mind
Full Certificate of Compliance, Level 2 ASP sign off and network approved metering, every time.
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
How long does a three phase upgrade in Fairfield usually take?
Most Fairfield residential upgrades are completed within 2 to 5 working days from approval. Endeavour Energy network coordination can add 1 to 3 weeks lead time depending on whether overhead or underground works are needed on your street.
Can I get a three phase upgrade done on a rented or tenanted property?
Yes, we regularly work with landlords and property managers in Fairfield. We coordinate timing with tenants and provide all compliance paperwork the agency needs on file.
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.
Will my existing switchboard need to be replaced?
Often, yes. Many Fairfield homes still have an older single phase board that cannot safely accommodate a three phase distribution. We assess this on site and include any switchboard work in the fixed quote.
Are you authorised to work on the Endeavour Energy network in Fairfield?
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 South-West Sydney.
