Findings you can act on
Periodic inspection and testing tells you whether an installation that has been in service is still safe to stay in service. It is a sampled exercise on most industrial sites: enough circuits, chosen well, to show whether the installation as a whole is holding up, with the sample size and the reasoning recorded on the certificate.
The value is in the observations, and observations are only useful if you can read them. C1 means danger is present and something must be done now. C2 means potentially dangerous, and remedial work is needed. C3 means improvement is recommended but nothing is unsafe today. FI means we could not see enough to decide and further investigation is required. We write each one in plain words as well as a code, so the person approving the spend understands what they are approving.
Where it helps, we add a thermographic survey of loaded switchgear. Thermal imaging finds the loose termination and the unbalanced phase that a dead test cannot, and it is done with the boards in service, which is usually the only time the fault is visible.
What we test
- Continuity and insulation resistance
- Polarity
- Earth fault loop impedance
- RCD operation
- Functional testing
- Thermal imaging where useful
How the work runs
From isolation plan to coded report.
Plan isolations
Agree which boards come off and when, so the testing fits your production rather than interrupting it.
Test
Dead and live testing circuit by circuit, with thermal imaging on loaded switchgear where it adds something.
Code observations
Each finding coded C1, C2, C3 or FI, located, photographed and written in plain words.
Report
An EICR with full test schedules, and a remedial estimate against the observations if you want one.
Your questions, answered.
Less than most people expect. Live testing — loop impedance, RCD operation, thermal imaging — needs the board energised. Dead testing needs it off, and that is where the outage goes. We group circuits so each isolation covers a sensible batch, work to the windows your production plan already has, and can spread a large site across several visits rather than asking for one long shutdown.
The certificate carries a recommended date for the next inspection, and for most industrial installations that is three years, sometimes one for harsher environments. It is a recommendation, not an expiry: a significant alteration, a change of use, damage, or a run of faults should bring it forward. Insurers and landlords sometimes set their own interval, which we are happy to work to.
Yes. Straightforward C2 items — a loose termination, a missing blank, a damaged gland — are often corrected during the visit if you want them to be, and the report records that they were closed on site. Anything larger comes back as a priced remedial item against its observation, so the estimate and the certificate refer to the same numbered finding.
