EICR codes explained: C1, C2, C3 and FI
Clear explanation of EICR observation codes, what they mean, how they affect the report outcome and what commercial clients and landlords should do next.
The code decides the next step
EICR codes are used to classify observations found during inspection and testing. They help separate immediate danger from potential danger, improvement recommendations and further investigation.
For landlords, facilities teams and commercial property managers, understanding the code is essential because it affects whether the report is satisfactory or unsatisfactory.
- C1 means danger present
- C2 means potentially dangerous
- C3 means improvement recommended
- FI means further investigation required
Coding should be consistent and clearly explained
Poorly explained coding causes disputes, delays and confusion. A useful report should identify the observation, explain the concern and make the next step clear.
London EICRs focuses on reports that can actually be used by property professionals, landlords and compliance teams.
- Clear written observations
- Practical remedial direction
- Sensible distinction between defects and recommendations
- Support after unsatisfactory reports

EICR Coding FAQs
Common questions about eicr coding for London commercial clients, landlords and property teams.
Does a C2 fail an EICR?
Yes. C2 observations normally make an EICR unsatisfactory because they indicate a potentially dangerous condition.
Does a C3 fail an EICR?
No. C3 observations are recommendations for improvement and do not normally make the report unsatisfactory on their own.
What does FI mean?
FI means further investigation is required because the inspector could not determine the full extent or cause of the issue during the inspection.
