Electrical faults are not only frustrating but potentially dangerous if ignored. At RCD Electrical, our highly qualified and NICEIC-certified electricians use safe, step-by-step processes to detect and resolve faults in residential and commercial properties.
From tripped circuit breakers and flickering lights to burning smells or non-functioning sockets, every issue requires a detailed diagnosis to avoid hazards like electrical fires or damage to appliances. This article guides you through the essentials of electrical fault finding, all carried out to the highest British standards by our professionals at RCD Electrical.
1. Identifying the Warning Signs
The first step in any fault finding is recognising the symptoms. Common electrical fault signs include:
-
Sockets not working
-
Lights flickering or dimming
-
RCDs or breakers frequently tripping
-
A burning smell near outlets or panels
-
Buzzing sounds from switches or circuits
If you notice any of these, it’s important not to investigate on your own. Call RCD Electrical on 02034882928 for safe inspection.
2. Initial Visual Inspection
Our engineers start with a full visual inspection of your installation. This involves checking for:
-
Damaged cables or insulation
-
Signs of overheating or arcing
-
Poor workmanship or outdated fittings
-
Burn marks or discolouration around outlets
This phase allows us to locate obvious faults before testing the circuit.
3. Isolation and Safe Testing
Safety is our top priority. Before testing, we isolate the circuit at the consumer unit and confirm it is dead using an approved voltage tester. No live work is carried out unless absolutely necessary and with all PPE in place.
We then use specialist equipment to test:
Each of these tests helps pinpoint exactly where the fault lies.
4. Locating the Fault
Once testing narrows down the area of concern, we physically inspect components—be it a faulty switch, degraded cable, or overloaded circuit. We never guess; our approach is systematic and accurate.
Where necessary, we may lift floorboards or inspect behind walls, always minimising disruption.
5. Fixing the Issue
Upon finding the fault, our electricians discuss the remedy with you and provide a transparent quote. Repairs may include:
-
Replacing damaged wiring
-
Upgrading consumer units
-
Fitting new sockets or switches
-
Repairing loose connections
-
Installing surge protection
All work complies with BS 7671 Wiring Regulations and is fully certified.
6. Final Testing and Certification
After repairs, we perform a full retest to ensure the system is safe and functional. A certificate of testing is issued, and your property is left clean and secure.
If requested, we can also carry out a full EICR (Electrical Installation Condition Report) to confirm the entire installation’s safety.
