FI stands for Further Investigation. It means additional inspection or testing is required before the electrician can determine the condition or safety of the affected part of the installation.

An EICR is generally considered unsatisfactory if it contains C1, C2 or FI observations, as these require immediate action, remedial work or further investigation.
