A C2 observation on an Electrical Installation Condition Report (EICR) indicates a potentially dangerous condition that requires urgent attention. There is no defined statutory deadline for C2 remediation, but HSE guidance and industry practice treat C2 items as requiring action within 28 days.
Under the EICR classification codes, C1 indicates danger present and requires immediate action, C2 indicates a potentially dangerous condition requiring urgent remedial action, and C3 indicates improvement recommended but not required for the installation to be considered satisfactory. A C2 sits between these -- the installation is not immediately dangerous, but a defect exists that could become dangerous if left, such as inadequate earthing, absent RCD protection where now required, or damaged accessories in a wet area.
Neither the Electricity at Work Regulations 1989 nor BS 7671 specifies a precise number of days within which a C2 must be remediated -- the word used is 'urgent'. This absence of a fixed deadline is often misread by operators as meaning there is no real time pressure. In practice, HSE guidance and accepted industry practice treat 28 days as a reasonable working benchmark for urgent remedial action, and any longer delay needs a documented justification.
An EICR with unresolved C2 observations is not, by itself, evidence of non-compliance -- the report itself is doing its job by flagging the issue. What becomes a compliance failure is the absence of any subsequent action: no work order raised, no remediation certificate obtained, no re-inspection to confirm the defect was fixed. Regulators and insurers assess the response to the EICR at least as closely as the EICR's findings.
Once a C2 item has been rectified, the electrician carrying out the repair should issue either a Minor Electrical Installation Works Certificate or an Electrical Installation Certificate, depending on the scope of work, confirming the specific defect has been corrected and the circuit or installation now complies with BS 7671. This certificate should be filed alongside the original EICR so that anyone reviewing the compliance file can see the full chain from observation to resolution, not just the flagged risk in isolation.
For each C2 finding, record the date identified, the specific defect, the date work was instructed, the date it was completed, and the certificate reference confirming remediation. This trail is what demonstrates active risk management if CQC, HSE or an insurer ever asks how the operator responded to a known electrical risk, and it is far more persuasive than simply pointing to the fact that an EICR was carried out.
