Why Upgrade Your Home’s Power Supply?

Make Room for Modern Living

Let’s be honest, our homes are working harder than ever. Between large air conditioners, multi-door fridges, work-from-home tech, backyard pools, and electric vehicles, we’re using a lot more electricity than we were just a decade ago.

Older electrical systems weren’t built for this. You might be noticing:

  • Circuit breakers tripping too often

  • Blown fuses

  • Warm power points or switches

  • Minor electric shocks

  • A higher risk of electrical fires

A supply upgrade helps your home meet today’s demands without the stress or safety risks.

Get Ready for Solar, EV Charging, and Future Growth

Melbourne homeowners are jumping on solar, and for good reason. But adding solar panels, battery storage, or an EV charger installation can overload your old switchboard if it’s not upgraded first.

Electric vehicle chargers usually need a dedicated 240V circuit. A lot of older homes in Melbourne only have a 40 or 60-amp supply, which just isn’t enough for high-demand appliances.

We’ll help bring your home up to speed. All our upgrades meet Australian standards like AS/NZS 3000:2018, so you can feel confident that everything is safe and compliant.

Replace Old and Unsafe Cabling

Some homes in Box Hill and nearby suburbs are still running on ageing mains wiring. The insulation may be worn down, and many of these older switchboards don’t have essential safety features like RCDs (safety switches), proper earthing, or surge protection.

These aren’t just upgrades, they’re legal requirements in Victoria.

We’ll make sure your home is compliant and protected from avoidable hazards. Give us a call to get started with a tailored solution.

  • Replace mains cabling – We remove the old cabling and install new TPS cables suited for today’s loads

  • Switchboard and main switch upgrade – We upgrade to single or 3-phase as needed, and fit safety switches and circuit breakers

  • New electricity meter (if needed) – For homes moving to 3-phase power or needing a modern meter, we’ll take care of the install

Single-Phase Supply Upgrades

Not sure whether to stick with single-phase or upgrade to 3-phase? Here’s a quick guide.

For homes with lower demand or smaller setups, a 63A single-phase supply is usually enough. It can handle most modern appliances, including EV chargers, without breaking a sweat.

You can also check out our blog post comparing single-phase vs three-phase to see which one is right for your home.

How Much Does It Cost?

Upgrading to a 63A single-phase supply usually costs between $4,500 and $7,000. The price depends on your existing setup, how accessible it is, and whether switchboards or meters need replacing.

We’ll inspect everything first and give you a free, clear quote.

Upgrade to 3-Phase Power in Melbourne

If you’re planning to run a home with big-ticket items like:

  • HVAC systems

  • Pool heaters or pumps

  • Industrial kitchen gear

  • Multiple EV chargers

...then a 3-phase supply is probably the way to go. It delivers more consistent power and handles large loads with ease.

How Much Does 3-Phase Cost?

Expect to pay between $5,000 and $8,000 for a standard 3-phase upgrade in Melbourne. Larger homes or trickier installs may cost more. Connection fees, underground cabling, and switchboard replacements are priced separately.

Switchboard Upgrades for Power Supply Changes

Upgrading your supply almost always means upgrading your switchboard too. A lot of older boards in Box Hill still don’t have safety switches or proper surge protection, and both are now mandatory.

What Will It Cost?

  • Single-phase switchboard: $800 to $2,000

  • 3-phase switchboard: $3,000 to $4,000

These are ballpark figures. Book an inspection and we’ll give you a detailed estimate based on your specific needs.

Underground Power Supply Upgrades

Want to get rid of those ugly overhead wires?

Underground power is a cleaner, safer option. It’s less likely to be knocked out by storms or falling branches and keeps your street looking tidy.

That said, it’s a more involved job. Trenching from the street to your home’s meter box can affect driveways or landscaping, and the complexity can push costs higher.

Expect to pay between $4,500 and $10,000, depending on your location and setup.

Residential Supply Upgrades FAQ’s:

  • Anywhere from $5,000 to $8,000 for standard homes. Larger or more complex setups may cost more. Connection and trenching fees are extra.

  • Absolutely, if your energy needs call for it. We’ll inspect your home and help you figure out what makes sense.

  • Frequent tripping, adding high-load appliances, or switching to solar are common signs. We can assess it for you.

  • Most Melbourne suburbs have access to 3-phase. Check with your electricity distributor or give us a ring and we’ll help you find out.

  • It can run multiple large appliances at once without straining your system, keeps voltage stable, and may even increase your home’s resale value.

  • Single-phase offers up to 63 amps, while 3-phase gives you around 80 to 100 amps.

  • Most homes do fine with single-phase. But if you’re planning to go big on energy use, 3-phase offers better performance and fewer risks.

  • We start with a full assessment, then organise permits, install new cabling, upgrade the switchboard, and test everything before arranging final sign-off and certification.
