Not sure if it’s time to call a licensed electrician? Here are five common warning signs we see in Auckland homes. Fixing issues early keeps your family safe and can save you money.
1) Lights flicker, dim or there’s a burning smell
Flickering or dimming lights can indicate loose connections or overloaded circuits. Any burning smell from switches or fittings is an urgent safety risk—turn power off to the affected area and call us.
2) Circuit breaker trips regularly
Frequent tripping suggests an overloaded circuit, faulty appliance, or a wiring fault. We can test the circuit, balance loads, and replace faulty breakers if needed.
3) No RCD protection
Residual Current Devices (RCDs) are designed to shut off power instantly if there’s a leakage, preventing electric shocks and fire risks. If your switchboard doesn’t have RCD protection, it’s time to upgrade. Modern switchboards with RCDs are now standard for safety in NZ homes.
4) Old or overloaded wiring
Homes built before the 1980s often have outdated wiring that isn’t designed for today’s appliances and technology. Cracked insulation, warm power points, or frequent power outages are signs your wiring may need replacing. Rewiring ensures your home stays safe and compliant with current electrical standards.
5) Sparks, shocks or buzzing outlets
If you notice sparks when plugging in appliances, hear buzzing from switches, or receive small shocks from outlets, don’t ignore it. These are serious red flags that require immediate attention from a licensed electrician to prevent fire or injury.

Frequently Asked Questions
Do I really need an electrician for flickering lights?
Yes. Flickering lights can be a sign of loose wiring, overloading, or even a failing circuit. It’s best to have a licensed electrician inspect the issue to prevent bigger risks.
What is an RCD and why is it important?
An RCD (Residual Current Device) cuts power immediately if it detects a fault or leakage. It’s a life-saving device that prevents electric shocks and fires. If your home doesn’t have RCD protection, we recommend upgrading your switchboard.
How often should my home’s wiring be checked?
For older homes, we recommend a safety check every 5–10 years. If your property is new, a professional check is usually needed when adding major appliances or renovations.
Are your electricians licensed and insured?
Yes. All of our electricians are fully licensed, EWRB registered, Site Safe accredited, and we carry $5 million public liability insurance for your peace of mind.
