When Flickering Lights Signal Immediate Danger
While a single flickering light might be as simple as an LED bulb reaching the end of its lifespan or an incompatible dimmer switch, persistent flickering across multiple rooms is a red flag.
It frequently indicates a loose neutral connection at your consumer unit or in a hidden ceiling junction box. A loose connection causes micro-arcing: electric sparks jumping across gaps, generating intense heat capable of smouldering dry timber.
