An EICR (Electrical Installation Condition Report) is a formal inspection and test of a property's fixed electrical installation. It covers the wiring, consumer unit, protective devices, earthing and bonding, socket outlets, switches, and all fixed electrical equipment.
The report is produced in accordance with BS 7671:2018+A4:2026 (Section 631), which specifies that an Electrical Installation Condition Report must be used for periodic inspection and testing of existing installations. It is not a pass or fail — it is a detailed condition assessment using a standardised observation code system.
The inspector carries out a visual inspection followed by a programme of testing: insulation resistance, earth fault loop impedance, RCD operation times, and continuity of protective conductors. Every observation is recorded on Schedules of Circuit Details and Test Results, which form part of the completed report.
The overall assessment is either Satisfactory or Unsatisfactory. An Unsatisfactory result means one or more C1 (danger present) or C2 (potentially dangerous) observations are present and remedial work is required.
