Code Summary
C1, C2, C3 and FI Explained
EICR codes tell you how serious an observation is and whether further action is needed before the installation can be considered satisfactory.
C1
UnsatisfactoryDanger present
There is an immediate danger or risk of injury. The electrician will normally make the danger safe before leaving if possible.
C2
UnsatisfactoryPotentially dangerous
The issue is not necessarily causing immediate harm, but it could become dangerous under fault conditions or normal use.
C3
Usually satisfactory if C3 onlyImprovement recommended
The installation could be improved, often to align more closely with current standards, but the observation is not classed as dangerous by itself.
FI
Unsatisfactory until investigatedFurther investigation
The inspector cannot confirm the safety of the issue without more investigation. It may lead to a C1 or C2 once properly assessed.

Frequently Asked Questions
Straight answers before you book electrical work.
Does a C3 fail an EICR?
A C3 is improvement recommended and normally does not make an EICR unsatisfactory by itself.
Which EICR codes make a report unsatisfactory?
C1, C2 and FI observations normally make an EICR unsatisfactory until the issue is made safe, repaired or investigated as appropriate.
Can an EICR code be confirmed without seeing the installation?
No. The checker explains common meanings, but the final classification depends on the installation and the competent inspector's judgement.
