EICR codes explained

After an EICR inspection takes place in your rental or commercial property, you will receive a copy of the EICR report. 

This report will advise if your inspection was 'satisfactory' or 'unsatisfactory'.

There are four EICR codes you need to be aware of, and this article will explain what these EICR observation codes mean.

C1 – Danger Present. Risk of Injury. Immediate remedial action required

This is the most high-priority code used in an EICR inspection. This means there is a risk of electric shock or fire if the issue is not made safe as soon as possible.

An example of a C1 code could be the exposure of live electrical parts, deteriorated insulation or broken light switches/plug sockets.

To resolve a C1 code, the issue will either need to be repaired or the relevant part/circuit isolated and taken out of use.

C2 – Potentially dangerous – urgent remedial action required

This means that this fault is not immediately dangerous in the same way as a C1 code is, but it could quickly become a hazard in the future.

An example of a C2 code could be the absence of mains protected bonding or earthing, or an RCD that does not trip when tested.

C3 – Improvement recommended

This means that this part of the installation is not in line with the wiring regulations, but it does not present any immediate danger. Alternatively, improving it would enhance the safety of the electrical installation.

An example of a C3 code could be the location of a plug socket which could potentially cause damage to a plug or flex.

Think of this code like an 'advisory note' on an MOT. You don't have to get it fixed, but it is recommended you do.

FI – Further investigation required without delay

This code means that the electrical engineer has identified an issue, but they need more time to investigate it. 

When they do this, they will be able to determine the severity of the issue.

What codes mean an EICR inspection is unsatisfactory?

If the inspection was unsatisfactory, this means that C1 or C2 work needs to be done, or FI codes need to be looked at in more detail.

What fault codes on an EICR prevent a new tenancy?

If you are getting an EICR inspection for a rental property, it's essential to make sure any C1, C2 and F1 issues are fixed before a new tenant moves in.

C3 issues don't need to be fixed for a tenant to move in, but it's always good to get them checked out before they cause bigger problems.
