Your switchboard is the one part of the house every circuit depends on. A lot of homes across the Mountains and Penrith are still running boards built for a kettle, a fridge and a few lights, and they are now being asked to carry induction cooktops, ducted air conditioning, solar and a car on charge.
We replace tired boards with a modern enclosure, individual protection on every circuit and room to grow. You get a board that is clearly labelled, fully tested, and backed by a Certificate of Compliance for Electrical Work.

Signs your switchboard is due
- Ceramic fuses with fuse wire, or a board with no safety switches
- Breakers that trip when the oven, heater and kettle run together
- Lights that dim or flicker when an appliance starts
- A warm board, buzzing, scorch marks or a burning smell (call us today for these)
- You are adding an EV charger, induction cooktop, air conditioning or solar
- A renovation or extension that needs new circuits and there is no room left
What goes into an NG switchboard upgrade
Protection on every circuit
Combined safety switch and circuit breaker (RCBO) per circuit, so one fault takes out one circuit and not the whole house.
A board sized for what is coming
We work out your maximum demand and leave spare capacity for the charger, cooktop or air con you have not bought yet.
Surge protection
Optional surge diverter to protect electronics from storm activity, which the Mountains gets plenty of.
Neat, labelled and photographed
Every circuit labelled in plain English. No mystery breakers.
Tested, with the numbers recorded
Insulation resistance, earth continuity, fault loop impedance and safety switch trip times measured and saved to a report.
Certified
Certificate of Compliance for Electrical Work issued on completion, as required in NSW.

Switchboard upgrades: FAQs
How long does a switchboard upgrade take?
A typical house board takes most of a day. Power is off for part of that time, and we agree the window with you beforehand. Larger boards, or jobs that need the incoming mains upgraded, can take longer and we will tell you that at quote stage.
Do I need a new switchboard to install an EV charger?
Not always. It depends on the capacity of your supply and whether the board has space and suitable protection for a dedicated charger circuit. We check this as part of every EV charger quote and only recommend an upgrade when it is needed.
My board has asbestos backing. Can you still upgrade it?
Yes. Many older boards have an asbestos-containing panel. It is handled and disposed of following the required safety procedures and replaced with a modern enclosure.
