An EICR (Electrical Installation Condition Report) is a formal inspection and test of a property's fixed electrical installation. It assesses the condition of the wiring, consumer unit, protective devices, earthing and bonding, sockets, switches, and all fixed electrical equipment.
The EICR is documented in accordance with BS 7671:2018+A4:2026 (Chapter 65, Reg 651.1), which requires that periodic inspection and testing of every electrical installation shall be carried out in accordance with the Regulations. Reg 653.1 further requires that an Electrical Installation Condition Report (EICR), based on the model in Appendix 6, shall be produced on completion — not an Electrical Installation Certificate, which is for new work only.
The inspector carries out a detailed visual inspection followed by a programme of testing (insulation resistance, earth fault loop impedance, RCD operation times, continuity of protective conductors). The results are recorded on Schedules of Circuit Details and Test Results. Each observation is classified using a code system (C1, C2, C3, FI) that indicates the severity and urgency of any defects found.
The overall condition of the installation is assessed as either Satisfactory or Unsatisfactory. An Unsatisfactory result means the installation has one or more C1 (danger present) or C2 (potentially dangerous) observations that require remedial work.
