How to code observations on a condition report

The coding of observations and non-compliance’s found during an Electrical Installation Condition Report EICR to the fixed wiring is a serious matter as an incorrectly coded observation could result in deeming an unsatisfactory installation as satisfactory.

It is the responsibility of the person carrying out the inspection to allocate an appropriate code (C1, C2, C3 or FI) to each of the defects found during the inspection.

The person carrying out the inspection should have an in-depth knowledge of the current version of BS 7671 IET Wiring Regulations and Guidance Note 3 Inspection & Testing. Depending on the type of electrical installation other BS Standards and Approved Building Documents may also apply.

​In addition to the above requirements the electrical inspector should be fully competent, highly skilled, suitably qualified and extensively experienced in testing and inspecting the particular type of electrical installation they are reporting on.

NAPIT have published an EICR Codebreakers guide to assist with the classification of observations for an EICR.

The NICEIC have published a Guide to Inspection, Testing and Certification which includes periodic reporting (EICR) updated to the 18th edition 2018.

EICR Observation Codes

EICR Codes

The four main Condition Report observation codes are Code 1 (C1), Code 2 (C2), Code 3 (C3) and Further Investigation (FI).

C1 = Danger present​

​A code 1 observation must be rectified and made safe without delay. 
An example of a C1 observation (it’s dangerous now!) would be the cover of a consumer unit missing hence exposing live parts. Any exposed live parts such as an open consumer unit busbar or an exposed live cable end would be classed as a code 1, as it is dangerous (right now) at the time of the inspection.


C2 = Potentially dangerous

A code 2 observation must be rectified as a matter of urgency.
An example of a C2 observation (potentially dangerous) would be no RCD protection to an external 13A socket. A C
