ELECTRICAL REPAIRS & FAULT FINDING
Based in Coulsdon, CMD Electrical Services provides fast, professional electrical repairs and fault finding for homes and businesses across South London, Surrey and Kent. Our NICEIC-approved electricians use advanced diagnostic equipment to identify the root cause of tripping circuits, power outages, faulty lighting, damaged wiring and other electrical problems.



COMMON ELECTRICAL FAULTS
Electrical faults can interrupt power, damage equipment and, if left unresolved, create serious safety risks. CMD diagnoses visible and concealed electrical problems affecting wiring, circuits, sockets, switches, lighting, fuse boxes, consumer units and commercial distribution systems.

Power loss affecting part of a property, or electrics that work intermittently, can result from a fault within a circuit, connection or electrical accessory.

A circuit breaker or RCD that continues to trip may indicate an overloaded circuit, damaged wiring or another electrical fault.

Burning smells, scorching or unusual heat around electrical accessories, wiring or a fuse box may indicate a serious fault requiring prompt attention.

Damaged cables, exposed conductors and loose electrical connections can affect reliability and create risks of electric shock, overheating or fire.

Cracked, loose, discoloured, buzzing, sparking or unusually warm sockets and switches should be inspected and repaired by a qualified electrician.

Lights that flicker, dim unexpectedly or stop working may be caused by a faulty fitting, switch, circuit connection or another wiring problem.
Not sure what is causing the problem? CMD can investigate the fault and explain the repair required.

OUR FAULT-FINDING PROCESS
Accurate electrical fault finding is essential before an effective repair can be completed. CMD combines experienced electricians, advanced diagnostic techniques and specialist testing equipment to pinpoint the root cause of electrical problems and determine the appropriate repair.
01
Tell us what has happened, which circuits or accessories are affected and whether you have noticed tripping, power loss, unusual heat, smells, sounds or visible damage.
02
Our electricians inspect the affected electrical installation and use specialist diagnostic equipment to investigate visible problems and faults concealed within the wiring.
03
The test results are assessed systematically to identify whether the fault involves the wiring, a circuit, an electrical accessory, protective equipment or connected appliances.
04
Once the fault has been diagnosed, CMD explains the problem clearly and completes the necessary repair. Where further work or replacement parts are required, you will receive a clear recommendation before additional work proceeds.
