Commercial EICR in Sheerness
Commercial EICR and fixed wire testing in Sheerness — Electricity at Work Regulations 1989 compliance across Swale.
CJA Electrical does commercial EICR and fixed wire testing across Sheerness and the wider Swale area. The legal framework for commercial premises is the Electricity at Work Regulations 1989 — and the EICR (also called fixed wire testing or periodic inspection) is the standard documentary evidence that the duty-holder is meeting that obligation. Whether you’re an office tenant, a retail unit operator, or a building owner with multi-tenanted commercial property, the inspection runs out of our Rochester base.
What Commercial EICR actually is
The technical name for what most Sheerness commercial clients call “fixed wire testing” is a periodic EICR — Electrical Installation Condition Report — to BS 7671. It documents the condition of the building’s permanent electrical installation at a specific point in time and identifies any departures from the current wiring regulations. The point of the document is twofold. First, it’s the duty-holder’s primary evidence of compliance with the Electricity at Work Regulations 1989. Second, it’s a maintenance planning tool — the C2 and C3 observations form the punchlist of work the building needs over the next inspection cycle to stay compliant.
When you need Commercial EICR in Sheerness
The standard inspection cycle for commercial premises follows IET Guidance Note 3. For most Sheerness offices, retail units, and small workshops that’s five years. Industrial premises, educational buildings, and laboratories typically run on a three-year cycle. Higher-risk environments — cinemas, theatres, swimming pools, petrol stations, places of public assembly — sit on annual inspection. Beyond the periodic cycle, an EICR is commissioned at change of occupancy (new tenant taking over a unit), after major refurbishment, after a known fault or insurance claim, and on insurance request at policy renewal. We’ve also done a few in Sheerness where a sale is in progress and the buyer’s surveyor has flagged the electrics for further investigation.

Standards and what compliance looks like
The two pieces of regulation that sit behind a commercial EICR are BS 7671:2018+A2:2022 (the IET Wiring Regulations — the technical standard the inspection works to) and the Electricity at Work Regulations 1989 (the legal duty on the employer or building owner to keep the installation safe and maintained). The EICR document itself follows the format set out in BS 7671 Appendix 6 — schedule of inspections, schedule of test results, list of observations with codes. Reports formatted to that standard are accepted by every insurer, every Swale local authority, and every commercial landlord we’ve worked with.
Testing schedule and remedials
Each circuit is tested in turn. Dead testing — with the circuit isolated — covers continuity of protective and bonding conductors, insulation resistance, polarity, and (for ring finals) ring continuity. Live testing — with the supply restored — covers earth fault loop impedance, prospective fault current, and RCD operating times. Every measurement is recorded on a schedule of test results and lodged with the certificate. Findings are recorded against observation codes (C1, C2, C3, FI) with a note against each. The summary on the front of the certificate gives an overall verdict — satisfactory or unsatisfactory — based on whether any C1 or C2 observations are present. C3 observations alone don’t make a report unsatisfactory; they’re recommendations rather than failures.

Why Sheerness property owners book CJA Electrical
We work with commercial clients across Sheerness the same way we work with domestic clients: same-day quotes, clear communication on what the inspection involves, transparent pricing, and a written report inside 48 hours. The difference on commercial is just the scheduling — most jobs run outside trading hours or in phased blocks during quieter periods. Reports are formatted to the standard BS 7671 template that insurers, managing agents, and HSE inspectors expect. Remedial work — if the report is unsatisfactory — is quoted separately so the duty-holder can plan the budget and prioritise C1 and C2 observations first.
How the work runs
The process from first call to delivered certificate is straightforward. Initial chat (phone or email) to confirm the premises type, circuit count, board count, and access constraints. A quote — fixed price where possible, otherwise capped — covering the testing itself. A scheduled testing visit, typically out-of-hours for retail and during business hours for office. Report supplied as a PDF within 48 hours of testing completing, formatted to BS 7671 with all observations coded. If anything is unsatisfactory, remedial work gets quoted separately so you can decide which observations to clear first. Once the remedials are done, the affected circuits are re-tested and a fresh certificate issued reflecting the post-remedial state of the installation.
What affects the price
Commercial EICR pricing is driven by the size of the installation — number of circuits, number of distribution boards, total accessory count — and the access conditions. Most Sheerness office EICRs come in as a fixed price after a five-minute scoping call. Industrial premises and multi-board commercial often need a brief site visit before the quote firms up. What’s included in the quote: the inspection, the testing, the written report formatted to BS 7671. What’s quoted separately: any remedial work needed to clear C1 or C2 observations after the report. We don’t bundle remedials into the inspection price — keeping them separate means the duty-holder can shop the remedial quote against other contractors if they want to.
FAQs
Will the testing damage anything?
No. The tests are non-destructive — insulation resistance and earth fault loop are low-current measurements that don’t stress the installation. The most disruptive part is the brief power cuts during dead testing, which is why we schedule around operations. We do power-down sensitive equipment (servers, control systems) properly before testing the circuits that feed them, and we coordinate with you on anything that can’t be cleanly isolated.
Do you handle three-phase installations?
Yes. Three-phase is normal on commercial Sheerness premises with higher load — workshops, larger offices with mechanical plant, industrial units. Test equipment, methodology, and reporting formats are the same as single-phase but with phase-specific readings recorded on the schedule.
What documentation do I get at the end?
The Electrical Installation Condition Report itself (front page with verdict, schedule of inspections, schedule of test results, list of observations) as a single PDF. We can split it into board-specific certificates if you need separate documents for individual tenants in a multi-tenanted building. The PDF is what your insurer, Swale Borough Council, and any future buyer’s surveyor will expect to see.
How often does a commercial EICR need doing?
IET Guidance Note 3 is the reference. Five years is standard for offices, retail, and most small commercial in Sheerness. Three years for industrial, educational, and most workshop premises. One year for higher-risk environments — cinemas, swimming pools, places of public assembly. The duty-holder can shorten these intervals based on risk assessment, and most insurers require evidence the building is on cycle.
What law requires a commercial EICR?
The Electricity at Work Regulations 1989. Regulation 4(2) makes the duty-holder responsible for keeping the installation safe and maintained, and Regulation 16 makes the employer responsible for ensuring competent persons do the testing. The EICR is the standard documentary evidence of compliance with both. Insurers commonly require it as a condition of policy.
Can testing be done out of hours so we don’t shut the business?
Yes. Out-of-hours testing is the default for retail units, restaurants, and most Sheerness commercial premises. We can also phase the testing across multiple visits if the building can’t sustain a single block. Tell us when you’re closed (or quietest) and we’ll plan the work to fit.
