Flickering lights, warm switch plates, a burning smell near sockets — none of these are 'normal'. Here's what each one actually means.
Most serious electrical faults don't happen out of nowhere — they give warning signs first. The problem is that many homeowners and shop owners write these signs off as minor annoyances instead of getting them checked. Here are five signs we see most often during health checks, and what they usually mean.
1. Flickering or dimming lights
Occasional flickering during a storm is one thing. Lights that flicker regularly, especially when an appliance switches on, often point to a loose connection somewhere in the circuit or an overloaded line.
2. Warm switch plates or plug points
A switch or socket should never feel warm to the touch. Warmth usually means a loose connection is causing resistance and heat build-up — a common precursor to a burnt socket or a fire risk.
3. A burning smell near outlets
This one should never be ignored. Turn off the circuit at the DB and get it inspected the same day if possible.
4. MCBs that trip often
An MCB tripping once in a while under heavy load is normal. Frequent, unexplained trips — especially on a single circuit — usually mean a fault in the wiring or a connected appliance.
5. Discoloured plug points
Yellowing or browning around a socket is a visible sign of past overheating, even if the socket seems to work fine today.
If any of these sound familiar, it's worth booking an Electrical Health Check rather than waiting for something to fail outright.
