Burning Smell from Electrics? What to Do Immediately

A burning smell from your electrical system is a serious warning sign that should never be ignored. It could indicate overheating wires, melting insulation, or an imminent fire. Here's what to do if you smell burning from your electrics.

Immediate Actions

1. Don't panic – but act quickly
2. Try to identify the source – is it a specific appliance, socket, or the consumer unit?
3. Unplug any suspect appliances – if safe to do so
4. Turn off the power – at the consumer unit if the smell is strong or you can't identify the source
5. If you see flames or smoke – evacuate and call 999

What Causes Electrical Burning Smells?

Overloaded Circuits

Too much current flowing through wires causes them to overheat. The insulation can melt, creating a burning plastic smell.

Loose Connections

Poor connections create resistance, which generates heat. This can cause arcing and burning at connection points.

Faulty Appliances

Internal faults in appliances can cause overheating. The burning smell may come from the appliance itself.

Damaged Wiring

Old, damaged, or rodent-chewed wiring can overheat and burn.

Overheating Consumer Unit

Loose connections or overloaded circuits in the consumer unit can cause burning. This is particularly serious.

Warning Signs to Watch For

• Burning or fishy smell near outlets or switches
• Discolouration around sockets or switches
• Warm or hot faceplates
• Flickering lights
• Buzzing or crackling sounds
• Frequently tripping breakers

What NOT to Do

• Don't ignore it – burning smells don't go away on their own
• Don't try to fix it yourself – unless it's simply unplugging a faulty appliance
• Don't keep using the circuit – if you've identified a problem area
• Don't use water on electrical fires – use a CO2 or dry powder extinguisher

When to Call 999

Call the fire service immediately if:

• You see flames or smoke
• The smell is very strong and you can't identify the source
• You can't safely turn off the power
• Anyone is injured

After the Immediate Danger

Once you've addressed the immediate situation:

1. Don't restore power until the problem is identified
2. Call an electrician to investigate
3. Don't use any appliance you suspect caused the problem
4. Document what happened for insurance purposes

Our emergency electrician service can respond quickly to investigate electrical burning smells.

Prevention

• Don't overload sockets with adapters
• Replace damaged cables immediately
• Have regular electrical inspections (EICR)
• Don't ignore warning signs like warm sockets or flickering lights
• Use quality electrical products

Conclusion

A burning smell from electrics is always serious. Act quickly to identify and isolate the problem, and don't hesitate to call for professional help. It's always better to be cautious with electrical safety – the consequences of ignoring warning signs can be devastating.
