Does a C3 Fail an EICR?
No — a C3 does not fail an EICR. C3 means improvement recommended; a report with only C3 observations remains Satisfactory. Only C1, C2 or FI cause a fail.
No — a C3 does not fail an EICR. A report that contains only C3 observations is declared Satisfactory.
Why C3 does not fail
The classification codes work like this:
- C1, C2 or FI → the report is Unsatisfactory.
- C3 only (or no observations) → the report is Satisfactory.
A C3 means "improvement recommended". The item is not dangerous and complies with the safety principles that applied when it was installed. Recommending an improvement is not the same as identifying a fault.
Should you still act on C3s?
Addressing C3 items is good practice but not required. It is often sensible to:
- fix them at the same time as any C1/C2 remedial work to save on visits; and
- treat them as a planned improvement list to keep the installation ahead of the curve.
The bottom line
If your EICR is Satisfactory with a few C3s, you are compliant. Plan the improvements when convenient. For the full outcome logic, see Satisfactory vs Unsatisfactory outcomes.
Frequently asked questions
If my EICR only has C3s, is it Satisfactory?
Yes. A report containing only C3 observations is Satisfactory. C3 items are recommendations for improvement and do not require remedial action to pass.

Code explanation
EICR C1 Code: Danger Present
A C1 on an EICR means danger is present and a risk of injury exists. It requires immediate action and always makes a report Unsatisfactory.

Difference Between C1 and C2 on an EICR
C1 means danger is present now and requires immediate action; C2 means potentially dangerous — safe now but a fault could make it dangerous. Both fail an EICR.

EICR C2 Code: Potentially Dangerous
A C2 on an EICR means potentially dangerous — no immediate danger, but a fault could make it dangerous. It requires urgent remedial action and fails the report.

Difference Between C2 and C3 on an EICR
C2 is potentially dangerous and fails an EICR, requiring urgent remedial work; C3 is a non-urgent improvement recommendation that keeps the report Satisfactory.
