Fault Finding & Electrical Repairs Plymouth
Accurate Diagnosis. Safe Repairs. Lasting Solutions.
Electrical problems aren’t always obvious. Intermittent faults, repeated tripping, power loss, or unexplained failures often require specialist investigation to identify the underlying cause. At Optima Electrical Services Ltd, we provide professional fault finding and electrical repair services to diagnose issues accurately and resolve them safely.
Our NICEIC-approved engineers use a structured, methodical approach to locate faults efficiently, carry out compliant repairs, and restore electrical systems to safe, reliable operation.
We support commercial and managed properties across Plymouth and the surrounding South West, providing reliable fault diagnosis and electrical repairs where safety or reliability is compromised.
Electrical Fault Diagnosis
Identifying the root cause, not just the symptom.
Electrical issues are not always obvious and can often be caused by underlying faults within circuits, components, or distribution systems. Our fault finding service uses a structured, methodical approach to accurately diagnose issues and identify the true source of the problem.
This ensures repairs are targeted, effective, and reduce the risk of repeat failures.
Safe & Compliant Electrical Repairs
Repairs carried out with safety as the priority.
Once a fault is identified, our NICEIC-approved engineers carry out repairs in line with current electrical regulations. From damaged cabling and faulty accessories to protective device failures, all work is completed safely and professionally.
Every repair is tested and verified to ensure the system is left compliant, reliable, and fit for continued use.
Reliable Long-Term Solutions
Preventing repeat faults and future disruption.
Recurring electrical issues often indicate deeper system weaknesses. Our fault finding and repair service focuses on delivering lasting solutions rather than temporary fixes.
Where appropriate, we provide clear recommendations for system improvements or planned maintenance to help prevent future faults and improve overall electrical reliability.
When Fault Finding Is Required
Not all electrical issues can be resolved with simple repairs. Fault finding is required when problems are recurring, unclear, or potentially linked to deeper system issues.
Common signs include frequent circuit tripping, loss of power, overheating equipment, unexplained shutdowns, or electrical issues that return after previous repairs. Our fault finding service is designed to identify root causes — not just symptoms — to prevent repeat failures.
Fault Finding & Repair Services
Our engineers investigate and resolve a wide range of electrical faults, including:
Intermittent Power Loss & Tripping Circuits
Diagnosis of circuits that trip unexpectedly or lose power without obvious cause.
Overheating & Electrical Stress
Identification of overloaded circuits, loose connections, or failing components that may pose safety risks.
Damaged or Deteriorated Wiring
Investigation and repair of cabling affected by age, wear, mechanical damage, or environmental factors.
Faulty Electrical Accessories & Equipment
Testing and replacement of defective switches, sockets, protective devices, and distribution components.
System Testing & Verification
Targeted testing to confirm fault resolution and ensure systems operate safely following repairs.
Permanent Repairs & Compliance Certification
All repairs are completed to current standards and tested in accordance with BS 7671 Wiring Regulations.
Who Our Fault Finding & Repair Services Are For

Frequently Asked Questions
Q1: What is electrical fault finding?
Fault finding is the process of investigating electrical issues to identify the underlying cause of a fault, rather than just repairing symptoms.
Q2: How is fault finding different from reactive maintenance?
Reactive maintenance restores systems quickly. Fault finding involves deeper investigation to diagnose recurring or unclear issues and deliver permanent solutions.
Q3: Do you repair faults once they’re identified?
Yes. Where possible, faults are repaired during the same visit. If further work is required, clear recommendations are provided.
Q4: Are repairs tested after completion?
All repairs are tested and verified to confirm safety and compliance before systems are returned to service.
Q5: Can fault finding help prevent future failures?
Yes. Identifying root causes reduces the risk of repeat faults and supports long-term system reliability.
Q6: Can fault finding link into planned maintenance?
Absolutely. Fault finding often informs future planned preventative maintenance to prevent recurrence.
