Fault Finding & Electrical Repairs in Bristol

Electrical faults can be frustrating, inconvenient, and in some cases genuinely dangerous. Whether you have an RCD that keeps tripping, a circuit that has gone completely dead, lights that flicker for no obvious reason, or a burning smell coming from a socket or switch — you need an electrician who can diagnose the problem accurately and fix it properly the first time. At MB Electrical, we carry out methodical electrical fault finding across Bristol using professional-grade testing equipment, including insulation resistance testers, loop impedance meters, thermal imaging, and circuit tracers.

Our fault finding process is thorough and systematic. Rather than guessing or replacing parts at random, we test each circuit methodically to isolate the exact location and cause of the problem. This means faster diagnosis, lower costs, and a repair that addresses the root cause rather than just the symptoms. We deal with every type of domestic electrical fault — from nuisance tripping and intermittent power loss through to serious issues like overheating connections, arcing, and earth faults in concealed wiring.

Many electrical faults develop gradually over time as connections loosen, insulation degrades, or circuits become overloaded by modern appliances that draw more power than the original wiring was designed for. Left unattended, a minor fault can escalate into a serious safety hazard. We always explain our findings in plain English, provide a clear quote for the repair, and carry out the work to the latest BS 7671 wiring regulations.

MB Electrical holds NICEIC Approved Contractor status — the highest tier of NICEIC accreditation. Unlike the Domestic Installer scheme held by many electricians, Approved Contractor status requires regular assessment of competence across domestic, commercial, and industrial electrical work, giving you confidence that every fault is diagnosed correctly and every repair meets the highest professional standards.
