If your EICR has come back with a C2, it's worth understanding exactly what that means before deciding what to do next.
C2 stands for "potentially dangerous." It doesn't mean there's an immediate risk of injury right now, but an inspector has identified something that could become genuinely dangerous if left unaddressed. Common examples include a circuit missing the RCD protection it needs, or wiring that's deteriorated beyond the point of doing its job properly. It sits between C1, which flags immediate danger requiring same-day action, and C3, which simply notes an improvement worth making at some point.
One thing that catches people out: a C2 still fails the report. It doesn't matter how the rest of the installation looks. Any C1 or C2 finding classifies the whole EICR as Unsatisfactory. A report containing only C3s, by contrast, can still pass. The system is built around risk rather than overall tidiness, which is why one issue can outweigh everything else looking fine.
In practice, this means the remedial work should happen soon, not necessarily the same day, but not left indefinitely either. Once it's carried out, it should be backed by proper documentation, typically a Minor Works Certificate or a new Electrical Installation Certificate, depending on the scope of the work.
For landlords specifically, this matters beyond just the paperwork. An Unsatisfactory EICR ties directly into your legal compliance obligations for the property, so addressing a C2 promptly and keeping the certificate on file is a genuine part of staying covered, not just a formality.
