Commercial fault finding by Perth's most reliable electricians, Northman Electrical Services

Faults are a natural part of life; despite our best efforts we can’t predict nor avoid them. What we can do is be there when you need us.


We’ve handled faults in aged care facilities, commercial kitchens, real estate properties, and high traffic retail areas. Places where downtime isn’t an option. With a vast experience in this area, we are able to diagnose the severity of the fault, likely understand what is required to fix it and give you a time frame and price to do so.


Downtime is something we take seriously and will endeavour to keep at a minimum for you.


Emergency work is available for our regular clients, including after hours. Because we know when a circuit trips or a light fails, you can’t afford to wait till Monday.


We aim to resolve issues on the first visit, using stocked vans and reliable diagnostics. If replacement parts are needed, we’ll provide a plan, clear pricing, and a timeframe you can work with.



Electrical issue? We’re on it. We’ll find the fault, fix it fast, and get your operations back on track.
