Here are the six findings we see most often across Sussex, what happens after an unsatisfactory report, and why the result is best read as a list of jobs rather than a verdict on your property.
An EICR assesses your installation against the current edition of BS 7671 (the wiring regulations), and the overall outcome is either satisfactory or unsatisfactory; inspectors do not use pass or fail. A report is unsatisfactory when it contains at least one C1, C2 or FI observation.
C1 means danger is present and there is an immediate risk. C2 means potentially dangerous: urgent remedial action is required. FI means further investigation is required without delay, used only where the inspector found something they genuinely could not assess on the day.
C3 means improvement recommended. A report containing only C3 observations is still satisfactory (a C3 alone never makes a report unsatisfactory), so a list of C3s is advice worth considering, not work you are compelled to do.
