FAQs

What types of electrical switches do you install and service in Cowan?

Our licensed electricians work with the full spectrum of residential and light-commercial switches, including standard rocker and toggle light switches, dimmers, weather-proof outdoor switches, fan-controller switches, two-way and three-way switches, as well as the latest Wi-Fi and Zigbee smart switches. Whether you need a simple replacement or a complete upgrade to a smart-home solution, we supply, install, test, and maintain products from trusted brands that meet Australian Standards.

How do I know if my existing light switch needs to be replaced?

Common warning signs include a noticeable delay when the light comes on, crackling or buzzing sounds, excessive heat at the switch plate, flickering lights, or difficulty toggling the switch. Discolouration, scorch marks, or a burning smell are urgent red flags that the internal contacts are failing. If you experience any of these issues, switch off the circuit at the switchboard and book an inspection. We can quickly test the circuit, identify whether the switch or wiring is the culprit, and replace faulty components to restore safe, reliable operation.

Are smart switches compatible with my current wiring and light fixtures?

In most Cowan homes built after the mid-1990s, the existing wiring (including the presence of a neutral wire in the switch box) supports direct installation of smart switches. Older properties may require the addition of a neutral or an earth upgrade for compliance. During our free onsite assessment, we check your switch boxes, bulb types (LED, CFL, incandescent), and Wi-Fi coverage to confirm compatibility. If upgrades are required, we provide a clear quote before work begins and ensure that all modifications meet AS/NZS 3000 (Wiring Rules).

What safety standards and regulations do you follow when installing switches in Cowan?

All our work is carried out by NSW-licensed electricians in accordance with the Australian and New Zealand Wiring Rules (AS/NZS 3000), AS/NZS 3100 for electrical equipment safety, and the Electricity (Consumer Safety) Regulation 2021. We issue a Certificate of Compliance Electrical Work (CCEW) for every new switch circuit or major alteration, demonstrating that the installation was tested for polarity, insulation resistance, and earth continuity. Additionally, we only use switches that carry the Regulatory Compliance Mark (RCM), ensuring they have been independently tested for Australian conditions.

How long does a typical switch replacement or new installation take?

A single like-for-like replacement often takes 20–30 minutes, including isolation, removal, inspection of the box and conductors, installation, and functional testing. Installing multi-gang or smart switches that require re-terminating multiple cables may take 45–60 minutes each. For new circuits, such as adding a switch in a new wall or upgrading to a two-way configuration, allow 1.5–2 hours due to extra cabling and wall repairs. We schedule appointments in two-hour windows, arrive with all common parts on hand, and aim to minimise downtime for your household or business.

Do you offer emergency switch repairs and what areas around Cowan do you cover?

Yes. Our 24/7 emergency service covers Cowan and neighbouring suburbs, including Berowra Heights, Mount Kuring-gai, Brooklyn, and Hornsby Heights. If a switch is sparking, smoking, or causing a loss of power, call our dedicated emergency line. We can usually arrive within 60 minutes, isolate the faulty circuit, make it safe, and provide either a temporary fix or a full replacement on the spot. All after-hours work still comes with the same workmanship warranty and compliance certification as our standard service.
