What is periodic electrical testing?

Periodic electrical testing, sometimes called fixed wire testing or an Electrical Installation Condition Report (EICR), assesses the safety and performance of your building’s electrical systems. It ensures that all fixed electrical installations, such as sockets, lighting, and wiring, remain safe, compliant, and fit for continued use.

Under the Electricity at Work Regulations, commercial properties must undergo a full inspection and test of all fixed electrical systems at least every five years. Regular testing helps identify deterioration, damage, or non-compliance before they become serious risks.

At Complii, our qualified engineers carry out thorough inspections and testing across all types of commercial and industrial environments, ensuring your electrical systems meet UK safety standards and perform reliably.

Your questions answered.

For commercial properties, testing is typically required every five years, though certain environments may need more frequent inspections depending on usage and risk.
It includes a full visual examination and electrical testing of all fixed installations, such as sockets, lighting, distribution boards, and wiring, to identify damage, defects, or non-compliance.
We plan all works carefully to minimise disruption. Testing can be completed outside normal hours or in phases to suit your business operations.
You’ll receive an EICR detailing all findings. Any C1 or C2 defects (danger present or potentially dangerous) will require prompt remedial action, which our engineers can carry out efficiently and safely.

The benefits of thermographic imaging

Thermographic imaging is a powerful tool for identifying potential electrical faults before they become serious problems. By using specialist thermal cameras, engineers can detect heat patterns that indicate issues such as overloading, loose connections, or failing components.

For businesses, this proactive approach helps reduce risks, avoid costly downtime, and demonstrate compliance with electrical safety regulations.
