Why Dedicated Circuits Matter?

Many appliances in Australian homes are sharing circuits that were designed 30 years ago for half the load. This causes:

What Are You Upgrading For?

Modern homes need modern power. Whatever you’re planning — we’ve installed it hundreds of times across Sydney.

Home Office

Extra power points, dedicated data circuits, and proper USB outlets for your WFH setup. No more extension leads or power boards.

EV Charger Circuit

EV Charger installation with dedicated power supply up to 22Kw — we handle the switchboard and cable run.

Air Conditioning

Ducted, split system, or multi-head — all AC units need a dedicated circuit. We size it correctly and future-proof the installation.

Kitchen Upgrades

Induction cooktops, steam ovens, and integrated appliances need their own circuits. We upgrade your kitchen sub-board and run new circuits clean.

Solar & Battery Storage

New solar or battery system? We install the AC disconnect, meter board modifications, and battery circuit — coordinated with your installer.

Pool & Spa

Pool pumps, heating systems, and underwater lighting all need proper GFCI-protected dedicated circuits. We do it to Australian Standards.

Extra Power Points

We add double GPOs, USB power points, and weatherproof outdoor outlets throughout your home — concealed cabling wherever possible.

Renovation Rewiring

Extension, second storey, or full reno? We handle the complete electrical scope — rough-in, fitoff, inspection, and certificate.

Commercial Fitouts

Office, retail, or warehouse — we design and install complete commercial electrical systems, including three-phase and high-load circuits.

How We Approach Power Upgrades

We don’t just add power points. We assess your whole electrical system first – checking your switchboard capacity, cable condition, and current load profile – to make sure what we install is safe, compliant, and long lasting.

 Trustindex verifies that the original source of the review is Google. I had a new cooktop and a heat light exhaust fan installed and I’m very happy with the service provided. They arrived on time, explained the installation process clearly and completed everything efficiently and professionally.
The cooktop was installed neatly and works perfectly. The heat light fan in the bathroom was also fitted with great attention to detail and it makes a big difference in ventilation and warmth. Everything was left clean and tidy after the work was finished.
Overall, the workmanship was excellent and the whole experience was smooth from start to finish. I would definitely recommend their services to anyone needing appliance or electrical installations.

 Trustindex verifies that the original source of the review is Google. Cameron was quick, professional, and very helpful. He responded quickly, came out the same day to inspect the issue, and clearly explained what the problem was with the main switch overheating. He replaced the faulty switch, fixed the wiring, and tested everything to make sure it was working properly.

The work was done neatly and efficiently. The price was very reasonable and the whole process was smooth.

Great service and highly recommended.

Frequently Asked Questions

Can I just add a power board instead?

Power boards are a temporary solution and can be a fire hazard if overloaded. They also don’t fix the underlying problem — an undersupplied circuit. Proper power point installation is safer, more reliable, and adds value to your property.

Will you need to cut into my walls?

Not always. In many cases, we can add power points with minimal disruption, depending on access through the roof, wall cavity or existing wiring. If cutting is needed, we’ll explain it clearly before starting.

Do I need council approval for power point additions?

No, standard power point additions usually do not require council approval. They do need to be installed by a licensed electrician to make sure everything is safe and compliant.

How much does it cost to add a power point in Sydney?

The cost depends on the location, wall type, access and how much wiring is required. We can give you an upfront quote before starting, so there are no surprises.
