EICR codes explained: what C1, C2, C3 and FI mean

An Electrical Installation Condition Report (EICR) records the condition of the fixed wiring in a property: the consumer unit, circuits, sockets, switches and lighting. Anything the inspector finds is listed as an observation and given a code. The codes tell you how serious each issue is and whether the report is satisfactory overall.

The four codes

Every observation on the report gets one of four codes:

Typical C1 examples are exposed live parts, such as a broken socket or a missing cover. Typical C2 examples include missing earthing or bonding, and signs of overheating.

Satisfactory or unsatisfactory?

If the report contains any C1, C2 or FI observations, the overall condition is unsatisfactory. If it only contains C3s, or nothing at all, it's satisfactory. Inspectors code observations using industry guidance, and experienced electricians should code consistently. If a code looks wrong to you, ask the inspector to explain the reasoning.

What to do if your EICR is unsatisfactory

• Landlords: the remedial work, or further investigation, must be carried out within 28 days, or within any shorter period the report specifies. You then need written confirmation from a qualified person, and must send it to your tenants and, if required, the council.
• Homeowners: there's no legal deadline, but C1 and C2 issues are safety risks and should be fixed promptly. Buyers and lenders may also ask about them.

You don't have to use the same company that did the inspection for the remedial work. Get a clear, itemised price and make sure you receive certification once the work is done.

How often do you need an EICR?

Private rented homes in England need one at least every five years, or sooner if the previous report recommends it. For owner-occupied homes, the usual recommendation is every ten years and when a property changes hands. Commercial premises are typically inspected every five years or more often, depending on the type of premises.
