C1 — Danger present
A C1 code means danger is present at the time of inspection. This is the most serious EICR code and usually requires immediate action.
Examples may include exposed live parts, severe overheating or direct electric shock risk.
Electrical Installation Condition Report Codes
EICR Codes Explained
EICR codes explain how serious an electrical observation is. The codes on an Electrical Installation Condition Report determine whether the installation is satisfactory, unsatisfactory or requires further investigation.
- ✓ C1: danger present and urgent action required.
- ✓ C2: potentially dangerous and remedial work required.
- ✓ C3: improvement recommended.
- ✓ FI: further investigation required without delay.
What are EICR codes?
EICR codes are used by the inspector to classify observations found during an Electrical Installation Condition Report. The code tells the landlord or property owner how serious the issue is and what should happen next.
C2 — Potentially dangerous
A C2 observation means the issue could become dangerous under fault conditions or continued use.
C2 observations are one of the most common reasons an EICR becomes unsatisfactory.
C3 — Improvement recommended
A C3 observation means improvement is recommended, but the issue does not normally make the EICR unsatisfactory on its own.
It often relates to older installations that would benefit from upgrading.
FI — Further investigation
FI means further investigation is required without delay.
The inspector has identified something that cannot be fully assessed during the normal inspection process.
Which codes fail an EICR?
C1, C2 and FI observations normally make an EICR unsatisfactory. C3 observations are recommendations and do not normally fail the report on their own.
EICR codes for landlords
Landlords should understand the difference between advisory comments and observations requiring action.
