Our Process

How We Diagnose Electrical Faults

Accurate fault diagnosis is essential before any repair work begins. Electrical issues can have multiple underlying causes, and replacing components without proper testing can lead to recurring problems or unnecessary costs.

Accurate fault diagnosis is essential before any repair work begins. Electrical issues can have multiple underlying causes, and replacing components without proper testing can lead to recurring problems or unnecessary costs.

Our electricians follow a structured diagnostic process to identify faults safely and efficiently.

Step 1

Initial Assessment and Symptom Review

We begin by understanding the issue in detail. This includes:

This helps narrow down potential causes before testing begins.

Step 2

Visual Inspection

A thorough visual inspection is carried out to identify obvious defects such as:

Many electrical faults can be identified at this stage, particularly in older London properties.

Step 3

Consumer Unit and Circuit Testing

We then test the affected circuits using calibrated diagnostic equipment. These are the same professional tests carried out during an EICR (Electrical Installation Condition Report) to ensure electrical safety and compliance.

These tests allow us to determine whether the issue is caused by:

Step 4

Load and Demand Analysis

In properties experiencing repeated tripping or overheating, we assess electrical load demand. This includes:

Where necessary, we recommend additional circuits or upgrades to bring the system in line with modern usage.

Step 5

Fault Tracing

For more complex issues, such as partial power loss or intermittent faults, we trace the circuit step by step to locate the exact point of failure. This may involve:

Our goal is to repair the root cause rather than apply temporary fixes.

Step 6

Clear Explanation and Quotation

Once the fault has been identified, we explain:

You will receive a clear quotation before any repair work proceeds.

Step 7

Repair, Testing and Certification

After completing repairs or upgrades, we:

This ensures the system is safe, compliant, and functioning correctly.

Why Professional Diagnosis Matters

Electrical faults should never be guessed. Incorrect diagnosis can result in:

By following a structured diagnostic process, we ensure faults are identified accurately and resolved properly the first time.
