What do C1, C2, and C3 codes mean?

These refer to EICR codes. (Electrical Installation Condition Report)

These codes are assigned to the various observations that are noted during fixed wire testing.

A C1 means you have a dangerous situation involving electricty. This could mean there are live parts which are exposed and can be touched freely. This would often require the power to be switched off, or a cover be put over them until a permanent repair can be made.

A C2 fault is quite common and means you have something that is potentially dangerous that will need repairing urgently. Typical faults include no earthing at a socket outlet, broken accessories, and degrading insulation around wires.

A C3 fault is very common and means you have some things that could be improoved for safety or to make the issues compliant. These include missing labels, cables not secured with clips, and outdated but still safe equipment.

Ben arrived promptly and was quick to set about with the testing, explaining everything as he went along so that I could understand what he was doing and why. He was very thorough in his work and did not mind at all that I was talking to him throughout.

Ben was amazing, rang on Tuesday went to answer phone as he was on a job but got back to me within 1hour, then came round the same day to assess the problem and had it fixed the following day. He explained everything that needed doing and was happy to explain as he was doing it.

Just Brilliant

We had a wiring fault causing the RCD on our consumer unit to trip, knocking out the circuit in our kitchen. Ben came out same day, identified the cause of the fault and whilst doing so explained what he was doing and what caused the issue.

Absolutely great service
