An expired or unsatisfactory report can invalidate cover and — for HSE-regulated activities — expose the responsible person to liability. What's at stake ## Left alone, small issues get expensive fast. The reason to book proper work now — instead of putting it off — comes down to what happens when you don't. Expired EICRs invalidating insurance Most commercial policies now require a satisfactory EICR within specified intervals. A lapsed report is a claim risk you haven't priced in. Reports that don't stand up to scrutiny A one-page tick-box EICR gets rejected by careful insurers and mortgage lenders. Ours are formatted to the schedules BS 7671 Section 653 actually specifies. C2 findings with no context "Potentially dangerous" without an explanation is useless when you're deciding what to fix first. Every observation on our reports includes a plain-English note explaining what it means and what remedy is proportionate. Our process ## A clear system, start to finish. - 01 Pre-visit planning We agree the extent of testing (limitations recorded formally), the isolation windows you can accommodate, and any circuits that must remain live for production or safety. - 02 On-site inspection and testing Visual condition survey followed by insulation resistance, earth fault loop impedance, polarity, continuity and RCD testing on the agreed sample. Live sampling where full isolation isn't practical. - 03 Findings coded and explained Every observation graded C1 (danger), C2 (potentially dangerous), C3 (improvement recommended) or FI (further investigation) — with a plain-English note explaining the practical implication. - 04 Report drafted same day Full BS 7671 report including circuit schedules, test results and observations, emailed the working day after inspection. - 05 Remedial quote alongside the report Where the report is unsatisfactory or improvements are recommended, you get a separately-priced, fixed-quote remedial schedule at the same time — no waiting weeks for a follow-up. Why it matters ## The outcome you actually get. - Reports insurers actually accept Formatted to the schedules BS 7671 Section 653 sets out, with circuit-by-circuit test results and clearly-coded observations. Accepted at first submission by mainstream commercial insurers. - Testing planned around production Weekend and out-of-hours slots available for sites where daytime isolation isn't practical. - One contractor for inspection and remedials If you want us to carry out the remedials, we can — but the report is written independently of the quote, so nothing is over-called to generate work. - Insurance-grade documentation PDF report, PDF certificate, and single-line diagrams where required — retained for 7 years and re-issuable on request. ## Ready to price the job properly?

Commercial and industrial periodic inspection is where a lot of contractors cut corners. A proper report takes time — full circuit schedules, test results recorded against each circuit, and observations graded to BS 7671 Appendix 6 rather than a home-rolled scoring system. Twenty years of doing this work across Cheshire commercial premises means we know what mainstream insurers, mortgage lenders and Cheshire East enforcement officers expect to see on the front page of the report. ### What we actually test Insulation resistance on every circuit within the agreed extent, earth fault loop impedance at each distribution board and at the furthest point of representative circuits, RCD trip times at 1x, 5x and half rated current, continuity of protective conductors and polarity. Live sampling where full isolation isn't achievable, with the limitations recorded formally on the report. ### How observations are coded C1 — danger present, immediate action required. C2 — potentially dangerous, urgent remedial action required. C3 — improvement recommended. FI — further investigation required. Every code carries a plain-English explanation so you can make an informed decision about scope and priority. ### Report limitations, done properly Any circuit that couldn't be isolated, any equipment that couldn't be accessed, any test that couldn't be completed — all recorded formally in Section D of the report. That's what makes the report defensible if it's ever challenged, not what makes it look bad. ### Remedials, quoted at the same time Where the overall report code is Unsatisfactory, you get a separately-priced, fixed-quote remedial schedule attached to the report. You decide whether we carry out the works. The report is written to the same standard whether we do the remedials or not. FAQs ## Straight answers. Anything else? Give us a call — we'll talk it through in plain English. 07782 231064 How often does a commercial installation need an EICR?Guidance under BS 7671 and IET GN3 typically points to every 5 years for commercial and 3 years for industrial premises, or on change of tenancy. Your insurer may specify shorter intervals — we work to whichever is more onerous. Can you test without shutting down production?Partial testing with live sampling is possible where full isolation isn't practical — the limitations are recorded formally on the report. For a fully valid report on the whole installation, at least one isolation window is required, and we can quote for out-of-hours to keep that window off production time. What if the report is Unsatisfactory?You receive a fixed-price remedial schedule attached to the report so you know exactly what needs doing and what it will cost. You're free to have the remedials done by anyone — we don't tie the report to the works. Are your reports accepted by insurers?Yes — full BS 7671 format including circuit schedules and full test results. Accepted at first submission by mainstream commercial insurers, mortgage lenders and letting agents. Who carries out the inspection?A qualified engineer holding City & Guilds 2391 Inspection & Testing, working under our NICEIC Approved Contractor registration. Full traceability on the report.
