Likely causes
- Loose bulb or LED driver
- Incompatible dimmer with LED globes
- Loose connection in the light fitting or switch
- Failing neutral connection at the switchboard — dangerous, needs urgent inspection
- Voltage fluctuations on the Energex supply (less common)
What to do
- Single light only — tighten the bulb and try a known-good one
- Multiple lights on one circuit — book an inspection of that circuit
- Lights flicker when an appliance starts — likely a loose neutral or overloaded circuit; needs an electrician
- Whole house flickering — check with neighbours; if everyone has it, it’s Energex; if just you, call us
