An EICR (Electrical Installation Condition Report) is essential for homeowners, landlords, and businesses in London. But when you receive the report, it may include codes like C1, C2, or C3—what do they mean?
At NICEIC Electricians, we believe in clarity. This article explains exactly what each EICR code stands for, what action is required, and how we help bring your property up to standard.
What Is an EICR?
An Electrical Installation Condition Report (EICR) is a formal inspection of your electrical system. It assesses the safety and condition of wiring, sockets, fuse boards, and fixed installations. It’s not just a formality—it ensures your electrical setup is safe and legal.
The inspection results in a report that includes observations, each given a code based on severity.
Understanding the EICR Codes
C1 – Danger Present: Immediate Action Required
Meaning:
This code indicates an immediate risk to safety. It means that the electrician found a fault that could cause electric shock or fire. The situation is dangerous and must be corrected immediately.
Examples of C1 Faults:
-
Exposed live wires
-
Broken or scorched sockets
-
Incorrectly installed equipment
-
Bare conductors accessible to touch
Action Required:
NICEIC Electricians will either repair the issue on-site (if safe to do so) or isolate the dangerous circuit and recommend urgent remedial work. A C1 automatically results in an unsatisfactory EICR.
C2 – Potentially Dangerous: Urgent Action Needed
Meaning:
C2 faults aren’t immediately dangerous but could become hazardous if left unresolved. These faults must be addressed as soon as possible to avoid escalation.
Examples of C2 Faults:
-
No RCD protection on socket outlets
-
Damaged light fittings
-
Loose wiring in a distribution board
-
Inadequate earthing or bonding
Action Required:
You’ll need to arrange for repairs as quickly as possible. NICEIC Electricians offer same-day remedial work to help you restore compliance and issue a new, satisfactory certificate.
C3 – Improvement Recommended
Meaning:
C3 means the installation is safe for continued use but could be improved to meet modern safety standards. This is the only code that does not fail your report.
Examples of C3 Observations:
-
Outdated consumer unit (fuse box)
-
No labelling on circuit breakers
-
Old wiring that still works safely
-
Lack of surge protection
Action Required:
C3 is advisory. You’re not legally required to take action, but it’s wise to consider upgrades—especially if you plan to sell, rent, or improve your property.
What Does "Unsatisfactory" Mean?
An EICR report is marked as unsatisfactory if any C1 or C2 issues are present. You’ll need to rectify the faults and provide written confirmation that the work has been completed. NICEIC Electricians will then issue a satisfactory certificate upon re-inspection.
