The inspector will control any required isolation during the visit. Before the appointment, clear access to the consumer unit, sockets, switches, cupboards, loft areas or locked rooms where possible. Tell the inspector about alarms, medical equipment, servers, freezers or business-critical equipment before testing begins.

Old wiring does not automatically mean an EICR will be unsatisfactory. The outcome depends on the condition, test results, safety of the installation, earthing, bonding, protective devices and any observed defects.

An EICR generally does not cover portable appliances like kettles, toasters, or extension leads. It focuses on the fixed electrical installation. Portable appliances are normally covered separately through PAT testing or appropriate appliance checks, not the EICR fixed wiring inspection.

The report should explain the observations and classification codes. C1, C2 or FI findings normally need remedial work or further investigation. Any required work should be completed by a suitable electrical professional, and written confirmation should be kept.

No. An EICR reports on the condition of an existing electrical installation. An Electrical Installation Certificate is normally issued for new electrical installation work, replacement work or a full rewire where applicable.

For rented homes in England, landlords must have electrical installations inspected and tested by a qualified person at least every 5 years, unless the report requires a shorter interval. They must also provide the report to tenants and the local council where required.
