Flickering Lights in Perth: Causes, Fixes and When to Worry
Flickering lights are easy to brush off, but they are one of the most common early warnings of an electrical problem in a Perth home. Sometimes flickering lights are harmless, and sometimes they point to a loose connection that could become a fire risk. Here are seven common causes, which ones are dangerous, and when to call an electrician.
Why do lights flicker? Flickering lights happen when the voltage to a fitting is unstable or a connection is intermittent. It can be as simple as a loose globe or as serious as a deteriorating connection in your switchboard or wiring. The trick is knowing which is which, because some causes are harmless and others need urgent attention.
7 common causes of flickering lights
- A loose or faulty globe, the simplest and most common cause
- An incompatible or failing LED dimmer
- A loose connection in the light fitting or switch
- A large appliance drawing power as it starts up
- Loose or corroded connections at the switchboard
- Worn or damaged wiring, often in older homes
- A supply issue from the network affecting the whole home
The harmless causes Not all flickering lights are cause for alarm. A globe that needs tightening or replacing, or an LED running on a dimmer not rated for it, are simple fixes. If only one light flickers and a new, compatible globe solves it, the problem was probably just the fitting, not your home’s wiring.
The dangerous causes Flickering lights become a worry when they signal loose or failing connections. If lights flicker across several rooms, dim when an appliance starts, or come with buzzing, warm switches or a burning smell, stop and call an electrician. Loose connections create heat, and heat in a wall or ceiling is a genuine fire risk.
Flickering across the whole house If lights flicker throughout the home, the cause is more likely at the switchboard, the main connection, or the network supply. This is not a DIY area. A licensed electrician can test where the voltage drop is happening and fix the connection safely, whether it is in your board or needs to be reported to the network.
What you can safely check Before calling, it is safe to try a new compatible globe, note whether one light or many are affected, and whether the flicker links to a particular appliance switching on. Never open the switchboard or poke at wiring. If flickering lights persist or come with any warning signs, book a licensed electrician.
When to call an electrician Persistent flickering lights, flickering in multiple rooms, or any sign of heat, buzzing or burning all warrant a professional. An electrician finds the loose or failing connection and fixes the cause, making your home safe again. The state’s Building and Energy sets the safety standards the work must meet.
LED globes and dimmers A very common modern cause is an LED globe paired with an old dimmer designed for halogen. The mismatch makes the LED flicker or buzz. Switching to an LED-compatible dimmer, or to globes rated for your existing dimmer, usually fixes it cleanly.
Could it be the appliance? If lights dip only when a specific appliance kicks in, an air conditioner, pump, oven or kettle, the issue may be that appliance pulling a large current, or a circuit that is undersized for the load. An electrician can confirm whether the wiring or the appliance is at fault.
Do not ignore a pattern A one-off flicker is rarely a problem, but a pattern is a message. Repeated dimming, especially with other symptoms, is your home telling you a connection is failing. Catching it early is cheaper and safer than waiting for it to fail completely.
