EICR Codes Explained – The Meaning of C1, C2 and C3

eicr codes explained

An Electrical Installation Condition Report (EICR) is a reliable way to ensure your electrical system is safe and fully functional. A qualified and competent contractor will check every aspect of your installation in line with the BS7671 standard and highlight any issues in their report.

Those issues will be categorised using the EICR codes c1, c2, c3 and FI. In this post, we’ll outline the meaning of C1, C2, C3 and FI to give you a better understanding of your EICR certificate.

EICR C1 meaning

Starting with the most serious code, EICR C1 indicates that danger is present on your electrical installation. The danger poses a risk of injury to anyone using the installation, meaning that immediate remedial action is required.

An example of a C1 code would be damage that leaves live conductors exposed and accessible. It’s recommended that you don’t use your electrical system until action has been taken. Failure to follow that recommendation could result in serious harm, damage, and costs from both repairs and legal proceedings.

EICR C2 meaning

Taking one step down, EICR C2 means that something on your installation is potentially dangerous. That could be, for instance, a lack of reliable earthing. Over time, that issue could worsen and lead to a shock risk.

As a result, C2 EICR codes require urgent remedial action. You may be able to continue using your system in the meantime, but you should arrange for repairs to be made as soon as you can. Like a C1 code, any issues categorised as C2 will mean the EICR is unsatisfactory until action is taken.

EICR C3 meaning

Moving onto EICR C3, this code means that improvements are recommended for your electrical installation. An example could be wiring that doesn’t meet the latest regulations, but that isn’t a risk in itself.

To be clear, no danger is present and there is no typical sequence of events that could lead to someone accessing live wires. As a result, EICR certificates can still be satisfactory when C3 issues are identified.

All that said, it’s best to have C3 issues rectified to improve the safety of your electrical installation and avoid more expensive issues developing over time.

What about FI?

Finally, there’s FI – which stands for further investigation. This is when the person completing the report notices something amiss that doesn’t necessarily breach the BS 7671 standards, such as a circuit that is not verified at the time of testing.

More specifically, it means further investigation is required without delay. FI codes can be enough to make an EICR unsatisfactory. If lots of circuits aren’t verified, for example, it would be irresponsible for an electrician to deem the installation satisfactory as a whole.
