Three Phase Power Upgrades Gold Coast
Adding a 22 kW EV charger, workshop machines or three-phase equipment can ask more of your supply than single-phase can give. Three-phase is one fix, but not always the right one. Our licensed electricians check your load first, then quote a fixed price for the upgrade that suits.

Do You Need Three-Phase Power?
You may need three-phase if you're adding big loads, such as a 22 kW EV charger or three-phase machinery, that a single-phase supply can't carry.
Often a switchboard upgrade or a 7 kW charger does the job without changing the supply.
Not sure? We'll check your board and load and tell you straight, with a fixed price before work starts.
Three-Phase May Suit
- 22 kW EV charger
- Three-phase machinery
- Large three-phase air conditioning
- Commercial cooking equipment
- Several big loads planned
A Board Upgrade May Do
- 7 kW EV charger
- No room on the board
- Old fuses or no safety switch
- One or two new circuits
- One circuit keeps tripping

How a Three-Phase Upgrade Works with Energex
From Energex's own guidance and the Electrical Safety Regulation 2026. Energex and your retailer set their own charges and timing.
A Licensed Contractor Does the Work
Energex says all electrical work for a change to an existing connection must be carried out by a licensed electrical contractor.
It Starts with a Connect Application
You can submit it yourself, or your electrical contractor can submit it for you. Energex then makes a connection offer for you to accept.
Then an Electrical Work Request
Once the offer is accepted, the electrical contractor submits an Electrical Work Request. Adding phases is lodged as a supply upgrade.

The Network Has to Be Able to Supply It
If the existing network can't support the upgrade, a supply availability enquiry is needed. The work request won't progress until the network is confirmed.

Your Retailer Handles the Meter
Energex is no longer responsible for installing or updating meters. Metering and connection fees are charged to you by your electricity retailer.
Homes Need a Safety Switch
With a few exceptions, an electrician can't do installation work in a home with no safety switch on the power points unless the job includes fitting one.

What Sets the Price of a Three-Phase Upgrade
We can't price it until we've seen your board and supply. These are the things that move the number.
- Street supply. Whether the network can supply three phases to your property.
- Overhead or underground. Your service type changes the work involved.
- The switchboard. Room for a three-phase board, or a new meter box.
- Circuits. More circuits to spread across the phases.
- Network charges. Energex and retailer charges are set by them, not us.
- Asbestos. A pre-2004 board may contain asbestos, which affects how it's handled.
- Access. Meter box location and any after-hours work.
Businesses and workshops

Three-Phase Power FAQ
Questions Gold Coast homeowners and businesses ask us about three-phase power.
Do I need three-phase power at home?
Most homes don't. Three-phase makes sense when you're adding loads a single-phase supply can't carry, such as a 22 kW EV charger, three-phase machinery or large three-phase air conditioning. If the real problem is an old fuse board, no room for circuits or a single new appliance, a switchboard upgrade is usually enough. We check your board and planned loads, then tell you which you need.
How do I know if my home already has three-phase power?
Look at the main switch on your switchboard without opening anything. A three-phase supply usually has a main switch three poles wide, where a single-phase main switch is usually narrower. That's a guide, not a guarantee. Don't remove covers or touch anything inside the board. If you're not sure, we can confirm it when we look at your board.
Do I need three-phase for a 22 kW EV charger?
Yes. A 22 kW charger runs on three phases at 32 amps each. On single-phase, a 32 amp charger gives about 7 kW. Check your car's onboard charger rating before you buy, because some EVs can't charge from an AC charger at 22 kW. We look at your car, board and supply and tell you which charger makes sense.
Can every property get three-phase power?
Not always. Energex has to confirm the network can supply the upgrade. If the existing network can't support it, a supply availability enquiry is needed, and the work request won't progress until the network is confirmed. That's why we check your supply before you buy a 22 kW charger or three-phase equipment, so you aren't left with gear you can't run.
Who applies to Energex for a three-phase upgrade?
Energex says you can submit the Connect Application yourself, or your electrical contractor can submit it for you. Once you accept Energex's connection offer, the electrical contractor submits an Electrical Work Request. Your retailer then quotes any metering and connection charges, which must be accepted before the work goes ahead. We explain each step before you commit.
How much does a three-phase upgrade cost?
It depends on your property, so we don't price it before we've seen it. The main factors are whether three-phase is available in the street, an overhead or underground service, the switchboard and meter box, and how many circuits need moving. Energex and your retailer set their own charges. For our work, you get one fixed price before it starts.
How long does a three-phase upgrade take?
Our electrical work is one part of it. The Energex connection offer and your retailer's metering work run to their own schedules, so we can't promise a finish date. We explain each step before you commit, tell you roughly how long the power will be off for the board changeover, and plan that shutdown with you.
Is a switchboard upgrade enough instead of three-phase?
Often, yes. If the problem is an old fuse board, no room for new circuits or no safety switches, a single-phase switchboard upgrade can fix it without changing your supply. Three-phase is about how much power the supply delivers and running three-phase equipment. We check your load and tell you which one you need before we quote.
