EICR Explained: Why Your Business Needs One and When
Electrical Installation Condition Reports are a legal requirement for many commercial premises. Here's what the process involves and what a C2 or C3 finding means.
// The Basics
An Electrical Installation Condition Report is a formal assessment of the safety of a building's fixed electrical installation. For most commercial and rental premises it's a legal obligation. Understanding what's involved helps you plan, budget and act on findings without unnecessary delay.
What the Inspection Covers
A qualified engineer will inspect the main switchgear, distribution boards, wiring systems, earthing and bonding, socket outlets, switches and accessories. Testing includes insulation resistance, earth continuity, RCD operation and loop impedance measurements. The inspection follows the schedule set out in BS 7671 and IET Guidance Note 3.
“A C2 finding isn't a scare tactic — it's a legal notification that remedial work must be completed before the installation can be considered safe for continued use.”
— Con-Tec Inspection Engineer
Understanding the Codes
Findings are classified C1 (danger present — immediate action), C2 (potentially dangerous — urgent remedial action), C3 (improvement recommended) or FI (further investigation required). A C1 or C2 finding means the installation cannot be certified as satisfactory. We provide a clear, itemised report of every finding and a separate remedial quotation.
How Often Do You Need One?
Commercial premises generally need an EICR every five years. Industrial and high-risk environments may require more frequent inspection. If you've recently acquired a building or are unsure of its electrical history, an EICR should be your first step.
