What Is Electrical Fault Finding?
Electrical fault finding is the process of identifying the cause of electrical issues in a property. These can include flickering lights, tripped circuit breakers, sparking sockets, or loss of power. While some faults may seem minor, even the smallest issue can lead to serious risks such as fires or electrocution if ignored.
At RCD Electrical, we use advanced diagnostic equipment and years of hands-on expertise to detect faults quickly and accurately. We don’t guess. We test, locate, and repair—ensuring long-term reliability and compliance.
Common Electrical Faults in the Home
Electrical issues may present themselves in several ways. Here are some common signs of electrical faults:
-
Frequent Tripping of the Circuit Breaker – This usually means a circuit is overloaded or there's a short circuit somewhere.
-
Flickering or Dimming Lights – Indicates poor wiring, loose connections, or voltage issues.
-
Buzzing Noises – If you hear buzzing behind walls or at switches, it could be due to faulty wiring or overloaded circuits.
-
Burning Smell or Discoloured Sockets – These are urgent signs of overheating or electrical arcing and require immediate attention.
-
Electric Shocks – Any shock, however small, is a red flag and should be investigated at once.
If you're experiencing any of these, call RCD Electrical on 02034882928 before it escalates.

Avoid overloading sockets or using multiple extension cords.
