FAQs
Explore our frequently asked questions to learn more about the specialised services provided by our certified Level 2 Electricians.
A switchboard upgrade involves replacing your old fuse box or switchboard with a modern unit fitted with circuit breakers and safety switches (RCDs). It ensures your home or business can safely handle today's electrical demands.
?You likely need one if your property has ceramic or rewirable fuses, circuit breakers that trip frequently, flickering lights, a burning smell near the meter box, or if you're adding solar panels, an EV charger, air conditioning, or doing a renovation.
Cost varies depending on your property size, the complexity of the existing wiring, and what needs replacing. High Demand Electrical provides free, no-obligation quotes — call us on 0402 559 777 or fill in the contact form and we'll get back to you fast.
Most residential switchboard upgrades are completed within a half to full day. Your power will be off for part of that time. We'll give you a clear timeframe before we start.
For work that involves the metering or network connection side — such as a meter box upgrade or reconnection to the Ausgrid/Endeavour Energy network — yes, a Level 2 ASP electrician is required. High Demand Electrical is fully Level 2 ASP accredited and handles both sides of the job.
Yes, and it's often the most efficient way to do it. If your current board can't support solar panels or an EV charger, we'll upgrade it as part of the same job — saving you time and a second call-out fee.
?It's not always legally required, but it may be triggered by a defect notice from Ausgrid or Endeavour Energy, or required as part of a renovation approval. Either way, an outdated switchboard is a safety risk worth addressing proactively.
Simple — call us on 0402 559 777 or use the contact form on this page. We service suburbs across South-West Sydney, Western Sydney, St George, Canterbury-Bankstown, and the Sutherland Shire. We'll confirm your booking quickly and give you a free upfront quote.
