How Much Does a Switchboard Upgrade Cost on the Mornington Peninsula? (2026 Guide)

Quick answer

Switchboard upgrade cost on the Mornington Peninsula depends on your home's size and number of circuits, whether new circuits are being added, the condition of the existing wiring, and whether you have single-phase or three-phase supply. The most reliable approach is a clear written quote from a licensed electrician after an on-site assessment.

If you own an older home in Frankston, Dromana, Mornington, or anywhere on the Peninsula, your switchboard has probably been working overtime. Many Peninsula homes built between the 1960s and 1990s still have outdated ceramic fuse boards — and upgrading them is one of the most common electrical jobs we do.

The cost depends on your home's size, the condition of the existing switchboard, and whether new circuits need to be added. Below, we break down exactly what drives the cost and what you get for your money.

What Affects a Switchboard Upgrade Quote

Key factors that determine the cost of your upgrade:

• ✅ Home size — more circuits means a larger enclosure and more labour
• ✅ Whether new circuits are being added (EV charger, AC, kitchen)
• ✅ Condition of existing wiring — remediation may be needed on older homes
• ✅ Single-phase vs three-phase supply
• ✅ Old ceramic fuse board vs existing circuit breaker board

What's Included in a Switchboard Upgrade?

A proper switchboard upgrade from a licensed electrician includes:

• ✓ Removal of the old fuse board or outdated switchboard
• ✓ Supply and installation of a new DIN-rail switchboard
• ✓ Modern circuit breakers (MCBs) for each circuit
• ✓ Residual Current Devices (RCDs/safety switches) as required
• ✓ Labelling of all circuits clearly
• ✓ Certificate of Electrical Safety (mandatory in Victoria)
• ✓ Notification to your energy distributor (e.g. United Energy or AusNet)

What Affects the Cost?

1. Size of Your Home

A 2-bedroom unit in Mornington has fewer circuits than a 5-bedroom house in Frankston South. More circuits mean more breakers, a larger enclosure, and more labour — all of which add to the cost.

2. Whether New Circuits Are Needed

If you're adding an EV charger, air conditioning, or a new kitchen as part of the upgrade, we'll need to run new cable to those points. This is where costs can climb — but it's almost always more cost-effective to do it all at once rather than piecemeal.

3. Your Existing Wiring Condition

Many older homes in Rosebud, Rye, and across the southern Peninsula still have older wiring — sometimes original cloth-insulated cable. If the existing wiring is in poor condition, additional work may be needed before a new switchboard can be safely connected.

4. Single-Phase vs Three-Phase

Most residential Peninsula homes are single-phase. If you need three-phase power — common for certain workshops, large air conditioning systems, or some EV chargers — the cost increases significantly, including a service upgrade from your energy distributor.

Why Do Older Peninsula Homes Need Upgrading?

The Mornington Peninsula has a large stock of older homes — fibro, weatherboard, and brick veneer builds from the 60s through the 80s are everywhere from Frankston to Rye. When these homes were built, a 40-amp or 60-amp fuse board was plenty. Today, with air conditioning, EV chargers, induction cooktops, and high-draw appliances, that same board is dangerously overloaded.

We also see a lot of holiday homes and investment properties across the Peninsula that haven't had any electrical work done in decades. A switchboard upgrade is often the first thing we recommend before any other work.

Is a Switchboard Upgrade Worth It?

Absolutely. Beyond the safety benefits, a modern switchboard:

• ✅ Protects your home from electrical fires
• ✅ Satisfies insurance requirements (some policies exclude claims from homes with old fuse boards)
• ✅ Enables future upgrades like solar, EV chargers, and smart home systems
• ✅ Is required before many renovations can proceed
• ✅ Adds value if you're selling — buyers and inspectors notice outdated boards

Frequently Asked Questions

How long does a switchboard upgrade take?

Most residential switchboard upgrades take 3–6 hours. The power needs to be off during the work, but we aim to minimise disruption. Larger jobs with new circuits may take a full day.

Do I need to notify my energy provider?

Yes — your electrician takes care of this. In Victoria, the Certificate of Electrical Safety is submitted to Energy Safe Victoria, and the relevant distributor (United Energy covers most of the Mornington Peninsula) is notified. You don't need to do anything.

Can I stay home during the upgrade?

Yes — you just can't use power during the work. Most families stay home; just plan for a few hours without electricity. We recommend doing it on a mild-weather day if possible (not mid-summer heat wave).

Is it covered by home insurance?

Switchboard upgrades are generally considered maintenance/improvement work, so they're not typically covered by home insurance. However, the insurance liability protects you after the fact — and some insurers require a modern switchboard to honour claims related to electrical fires.
