Received an EICR with fault codes and not sure what they mean? Here is a plain-English breakdown of every code, what action is required, and what happens if you don't act.
Danger present — immediate action required
A live risk of electric shock or fire exists right now. The electrician must make the fault safe before leaving where possible. The EICR is automatically Unsatisfactory.
Potentially dangerous — fix within 28 days
Not an immediate threat but likely to become dangerous. Landlords must fix and evidence all C2 faults within 28 days or risk a fine of up to £30,000. EICR is Unsatisfactory.
Improvement recommended — no legal obligation
The installation is safe but doesn't meet current best practice. A C3 alone does not make the report Unsatisfactory. No legal obligation to fix, though improvement is recommended.
Further investigation required
Something cannot be fully assessed during the standard inspection. The report stays Unsatisfactory until the investigation is completed and the issue resolved.
Common C1 examples
- Exposed live conductors accessible to touch
- Missing earth on a bathroom circuit
- Severely damaged cable in a consumer unit
- Live parts inside a damaged socket or switch
Common C2 examples
- No RCD protection on socket circuits
- Undersized fuse protecting a high-demand circuit
- Inadequate earth bonding to gas or water pipework
- Bathroom light fitting with inadequate fire/IP rating
- Old wiring showing signs of deterioration
