About the Service
The Earth Fault Loop Impedance Test checks if your electrical system can safely trip protective devices like MCBs during a fault. It ensures that any current flowing through a fault has a low-resistance path to earth, helping avoid electric shock, fire hazards, and equipment damage. This test is essential for verifying system safety and compliance with standards like BS 7671.

Popular questions
What is Earth Fault Loop Impedance testing?
It checks if your system will disconnect during a fault.
Will the test trip my RCDs?
We use No, we use “no-trip” testers to avoid interruptionGI plates/pipes, coal, salt, and sand for conductivity.
How often should the test be done?
Typically during installations or every 3–5 years.
Do I get a certificate after testing?
Yes, we provide full documentation for compliance.
