Practical guidance from Kore Electrical
The practical answer
An EICR is a structured inspection and test of the fixed electrical installation. It is not a quick visual check and does not cover portable appliances. The electrician agrees the extent and limitations, inspects the installation and tests circuits and protective measures. The report records observations and results. C1 indicates danger present, C2 potentially dangerous, FI means further investigation is needed without delay and C3 is an improvement recommendation.
This guidance is general and cannot replace inspection or testing of the actual installation. If there are signs of danger, isolate the affected circuit where safe and seek professional help.
How should I prepare?
Make the consumer unit and sockets accessible, and mention solar panels, batteries, EV charging or sensitive equipment before the appointment. Testing normally involves planned power interruptions. Agree access and any limits to the inspection in advance.
Does an unsatisfactory report mean a full rewire?
No. The report identifies particular observations; it does not automatically prescribe a whole-house rewire. C1, C2 or FI observations make the outcome unsatisfactory. Ask for the findings to be explained and any investigation or remedial work to be scoped separately. C3 alone is an improvement recommendation.
What should I send with a landlord enquiry?
Send the full previous report if available, the property postcode, access arrangements and the next inspection date stated on the report. Include any known changes since the last inspection. See our landlord electrical services.
