Mains Power Upgrades

A mains power upgrade involves increasing the capacity of the electrical supply coming into your property. This allows your home to safely handle higher electrical loads without overloading circuits or causing performance issues.

In many older homes, the existing supply was designed for far fewer appliances and lower overall demand. As usage increases, this can lead to limitations that affect both safety and functionality.

Upgrading the mains supply typically includes improvements to the incoming power cable, metering setup and switchboard, ensuring the system can support current and future needs.

Many homeowners don’t realise their mains supply is undersized until problems start to appear. In some cases, upgrades are recommended before issues develop, particularly when planning major electrical changes.

You may need a mains power upgrade if you are:

• installing new air conditioning systems
• upgrading to an induction cooktop
• adding an EV charger
• renovating or extending your home
• experiencing frequent circuit overloads
• unsure if your system can support increased demand

If your electrical system is being pushed beyond its capacity, upgrading the mains supply can prevent ongoing issues and improve overall reliability.

Every property is different, but a mains upgrade generally involves several key components working together to increase capacity and improve safety.

We typically upgrade:

• incoming supply cables to thicker, higher-capacity wiring
• metering equipment to meet current standards
• switchboards where required to support increased load

We also assess how your entire electrical system performs, ensuring the upgrade integrates properly with existing wiring and appliances.

All work is completed in accordance with Australian Standards and local energy provider requirements.

Modern homes rely on electrical systems far more than they did in the past. Appliances such as air conditioning systems, induction cooktops and EV chargers require consistent and reliable power to operate safely.

Without sufficient capacity, these systems can:

• overload circuits
• reduce overall system performance
• increase the risk of electrical faults

A mains power upgrade ensures your system can support these appliances without compromise, both now and into the future.

If you’re planning a renovation or extension, it’s important to consider whether your existing mains supply can support the additional load.

Many renovation projects focus on layout and design, but overlook the limitations of the existing electrical system. Upgrading your mains supply early in the process helps avoid delays, rework and unexpected costs later.

We work closely with homeowners to ensure electrical systems are ready to support renovation plans safely and efficiently.

What is a mains power upgrade?
A mains power upgrade increases the capacity of the electrical supply to your property, allowing it to safely handle modern appliances and higher energy use.

Do I need a mains upgrade for an EV charger or air conditioning?
In many cases, yes. High-demand appliances can require additional capacity to operate safely and efficiently.

Will my switchboard need to be upgraded as well?
Often yes. If your existing switchboard cannot support the increased load, an upgrade may be required as part of the process.
