EICR advice
Plain-English explanation of common EICR observation codes and why context matters.
This is general customer guidance only. Electrical work, testing, certification and pricing must be reviewed by VLV Electrical Ltd.
C1 means danger present. C2 means potentially dangerous. C3 is an improvement recommendation. FI means further investigation is required or recommended to determine the condition.
Observation codes should be reviewed with the report limitations, installation condition and inspector judgement. Do not assume the outcome from a generic example.
C3 observations are improvement recommendations and do not normally make an EICR unsatisfactory on their own.
Send the property type, postcode, access notes and photos or reports where safe. VLV will review the enquiry before confirming scope, price, booking or certification.
