Classification & reporting

How observations are coded, how those codes drive the overall assessment, and which certificate or report is the correct document for the work.

EICR classification codes

C1 — Danger present, risk of injury, immediate remedial action required. C2 — Potentially dangerous, urgent remedial action required. C3 — Improvement recommended (advisory). FI — Further investigation is advised (advisory).

Code	Meaning	Action

C2	Potentially dangerous	Urgent remedial action required
C3	Improvement recommended	Advisory
FI	Further investigation advised	Advisory

BS 7671 Appendix 6, pp.547-549

Overall assessment rule

The overall assessment is unsatisfactory ONLY where a C1 or C2 is recorded. C3 and FI are advisory and do not affect the overall assessment, though they should be given due consideration.
