? Common Electrical Faults and How to Spot Them
As a trusted Cambridge electrician, we’re often called out to fix electrical issues that could have been spotted (and sorted!) sooner. Electrical faults can pose serious safety risks if left unchecked, from electric shocks to potential fire hazards.
Here are some of the most common electrical faults in UK homes—and how you can identify them early.
1. ? Flickering or Dimming Lights
If your lights flicker or dim without reason, it could be a sign of:
-
Loose wiring
-
Overloaded circuits
-
Faulty light fittings or switches
What to watch for:
Does it happen when a certain appliance is turned on? That could mean the circuit is overloaded or improperly wired.
2. ? Tripping Circuit Breakers
Circuit breakers are designed to protect your home, but frequent tripping usually means:
-
Overloaded circuits
-
Faulty appliances
-
Ground faults or short circuits
Tip: If one circuit trips repeatedly, call a qualified electrician to investigate.
3. ? Burning Smell or Discoloured Sockets
A burning smell near switches or sockets is a major red flag. This could indicate:
-
Overheating wires
-
Loose connections
-
Damaged insulation
What to do: Turn off the power at the consumer unit and call an electrician immediately.
4. ? Electric Shocks
Getting a small zap when you touch a plug, switch, or appliance? It may signal:
-
Improper earthing
-
Faulty wiring
-
A damaged appliance
This should never be ignored—it can be a sign of a serious safety issue.
5. ? Old or Damaged Wiring
In older properties, wiring can degrade over time or no longer meet current safety standards.
Signs of ageing or faulty wiring:
-
Fabric-covered or black rubber cables
-
Fuse boxes instead of modern consumer units
-
Sockets that feel warm to the touch
A periodic EICR (Electrical Installation Condition Report) can identify these issues before they become dangerous.
6. ?? Faulty Light Switches or Plug Sockets
If your switches or sockets feel loose, don’t always work
