When you receive an Electrical Installation Condition Report (EICR), you might find yourself staring at a document filled with various codes and classifications that seem more like a secret language than useful information. Understanding these codes is crucial for property owners, landlords and businesses, as they directly impact your electrical safety, legal compliance and potentially your insurance coverage.

In this article, we'll explain in detail what the different codes appearing on your EICR mean and what your next steps should be after receiving your full report.

 

Understanding EICR Codes

An EICR uses a standardised coding system to classify the condition and safety of electrical installations. These codes follow British Standard BS 7671 (the IET Wiring Regulations) and provide a clear, consistent way for qualified electricians to communicate their findings. Rather than subjective descriptions, these codes offer precise classifications that help you understand exactly what action, if any, needs to be taken.

The coding system serves multiple purposes beyond simply identifying problems. It helps prioritise remedial work, ensures consistency between different electrical contractors, and provides a clear audit trail for regulatory compliance. For landlords, these codes are particularly important as they form the basis of your legal obligations under current electrical safety regulations.

 

The Four Main EICR Classification Codes

 

Code C1: Danger Present - Immediate Action Required

A C1 classification represents the most serious finding on an EICR. This code indicates that there is immediate danger to persons or property, requiring urgent remedial action. When a C1 code appears on your report, the electrical installation poses an immediate risk that could result in electric shock, fire or other serious harm.

Common examples of C1 issues include exposed live parts that can be touched, missing covers on consumer units, damaged cables with exposed conductors, or installations showing signs of overheating or burning. The electrical contractor will typically isolate the dangerous circuit immediately to prevent harm, which means part of your electrical system may be out of action until repairs are completed.

If your EICR contains any C1 codes, you cannot receive a satisfactory certificate, and the installation is considered unsafe for continued use. This has significant implications for landlords, as you cannot legally rent out a property with outstanding C1 issues, and insurance companies may refuse claims if dangerous electrical conditions were known but left unaddressed.

 

Code C2: Potentially Dangerous - Urgent Remedial Action Required

C2 classifications indicate potentially dangerous conditions that, while not immediately life-threatening, could become dangerous under certain circumstances or if left unaddressed. These issues require urgent attention and should be rectified as soon as possible to prevent them from escalating to C1 status.

Typical C2 issues include circuit protection devices that are incorrectly rated, inadequate earthing arrangements or electrical equipment installed in inappropriate locations such as bathrooms. You might also see C2 codes for missing RCD (Residual Current Device) protection where it should be present, or signs of deterioration that could lead to failure.

Like C1 codes, the presence of any C2 classifications means your EICR will be marked as unsatisfactory, indicating that remedial work is essential before the installation can be considered safe. The key difference is timing - whilst C1 issues require immediate action, C2 issues should be addressed urgently but don't necessarily require the circuit to be isolated immediately.

 

Code C3: Improvement Recommended

C3 codes identify areas where improvements are recommended but not essential for safety. These observations highlight installations that, whilst not dangerous, don't fully comply with current regulations or best practices. Importantly, C3 codes do not prevent you from receiving a satisfactory EICR certificate.

Examples of C3 issues include older consumer units that function adequately but don't meet current standards, minor labelling deficiencies or the absence of additional protection that would be required in new installations but isn't mandatory for existing ones. You might also see C3 codes for cosmetic or visual issues like surface-mounted cables that could be better routed, or accessories that are showing signs of age but remain functional.

While C3 improvements aren't legally required, addressing them can improve compliance with current standards and potentially prevent future problems. For commercial properties or rental properties, tackling C3 issues proactively demonstrates good management and could prevent minor issues from becoming major problems during future inspections.

 

Code FI: Further Investigation Required

The FI code indicates that the electrical contractor was unable to fully inspect or test a particular aspect of the installation, meaning further investigation is needed to determine its condition. This isn't necessarily a safety concern, but rather an acknowledgement that the inspection was incomplete in certain areas.

Common reasons for FI codes include inaccessible areas such as cables buried in walls, equipment that was switched off during the inspection, or installations where the full extent of the wiring couldn't be traced. You might also see FI codes where specialist equipment or expertise is needed to properly assess certain installations, or where other trades need to provide access before electrical testing can be completed.

FI codes don't automatically make your EICR unsatisfactory, but they do indicate that the inspection is incomplete. To achieve a fully satisfactory report, these areas will need to be investigated and assessed, which may require additional visits from the electrical contractor or coordination with other trades to provide access.

 

What Each Code Means for Your Next Steps

EICR codes don't exist in isolation - they must be understood within the context of your specific installation and circumstances. The same electrical condition might receive different codes depending on factors such as the environment, usage patterns, and the age of the installation. For example, an older consumer unit might receive a C3 code in a domestic property where replacement would improve safety but isn't essential, whilst the same unit in a commercial environment with heavy usage might warrant a C2 code due to the increased risk. Similarly, missing RCD protection might be coded differently depending on the circuits it affects and their intended use.

This contextual approach means that two similar properties might receive different codes for seemingly identical issues. Your electrical contractor should explain the reasoning behind each code and how your specific circumstances have influenced their assessment. This understanding helps you make informed decisions about remedial work and future maintenance planning.

 

How EICR Codes Relate to Compliance and Legal Requirements

The EICR coding system directly links to your legal obligations, particularly if you're a landlord or operate a commercial property. Current regulations require landlords to ensure their electrical installations are safe and to provide tenants with a valid EICR certificate.

Any C1 or C2 codes on your EICR indicate that the installation doesn't meet the required safety standards, which means you're not compliant with current regulations. This non-compliance can have serious consequences, including potential prosecution, insurance issues, and liability for accidents or incidents. Even C3 codes, whilst not preventing compliance, should be carefully considered. Whilst not legally required, addressing C3 issues demonstrates good practice and can help prevent future compliance problems. For commercial properties, C3 improvements might be particularly important for maintaining insurance coverage and meeting health and safety obligations.

 

Planning Remedial Work Based on EICR Codes

When your EICR identifies issues requiring attention, planning the remedial work effectively can save both time and money whilst ensuring safety. Start by understanding which codes require immediate action - any C1 codes must be addressed before the affected circuits can be safely used, whilst C2 codes should be scheduled urgently.

Consider grouping remedial work logically to minimise disruption and costs. If multiple circuits need attention, it might be more efficient to complete all the work during a single visit rather than multiple call-outs. Similarly, if access requirements are similar for different issues, coordinating the work can reduce the overall impact on your property use.

For commercial properties or rental properties, timing remedial work can be particularly important. Plan work during periods of low occupancy where possible, and ensure you comply with any notice requirements for tenants. Remember that some remedial work might require power isolation, so consider the impact on tenants, security systems, and refrigerated goods.
