That low humming or buzzing from a socket can be really unsettling - and honestly, we get it. You're right to pay attention. A buzzing socket isn't something to ignore, but it's not always an emergency either. Let's talk through what's going on and when you need to act.
The Why: What's Actually Going On
A buzzing socket usually comes down to a few common culprits. Loose connections are the number-one cause: over time, screws inside the socket can work loose, especially with high-draw appliances. When the current flows through a poor connection, it creates vibration (and that buzz you're hearing). Age and wear also play a part - older sockets with worn contacts can arc slightly when plugged in. Overloading is another: if you're running multiple high-power devices from one socket (or a daisy-chain of extensions), the wiring and contacts can overheat and buzz. In rare cases, it can indicate a more serious fault, which is why we always recommend getting it checked.
Roy's Pro Tip
Before you call an electrician, try unplugging everything from that socket and the ones next to it. If the buzzing stops, the fault might be with a specific appliance. If it continues with nothing plugged in - that's when you definitely need a pro. Don't ignore it.
Safety Warning
Stop and call an electrician immediately if: the socket feels warm or hot to the touch; you smell burning; the buzzing is loud or accompanied by sparks; or the socket has ever tripped the RCD or circuit breaker.
