Commercial EICR in Maidstone
Commercial EICR and fixed wire testing in Maidstone — Electricity at Work Regulations 1989 compliance across Maidstone.
CJA Electrical does commercial EICR and fixed wire testing across Maidstone and the wider Maidstone 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
Fixed wire testing — to use the term most commercial clients in Maidstone are familiar with — is a periodic inspection and test of every circuit in the building’s fixed installation. The inspection has two parts: a visual survey of the consumer unit, distribution boards, and accessible accessories, then dead and live electrical testing on each circuit (continuity, insulation resistance, polarity, earth fault loop, RCD operation). What lands on the report is a formal opinion of whether the installation is satisfactory or unsatisfactory against BS 7671, with each observation coded so the duty-holder knows what’s urgent and what isn’t. C1 means immediate danger, C2 potentially dangerous, C3 improvement recommended, FI further investigation required.
When you need Commercial EICR in Maidstone
Frequency is set by IET Guidance Note 3 based on the building’s use, the environment, and the population at risk. Five years is the starting point for offices, small retail, and light commercial in Maidstone. Three years for premises with significant equipment loading (industrial, workshops, server rooms, plant rooms). One year for any premises where loss of power presents a serious risk or where the building hosts high public throughput. The duty-holder can shorten these intervals based on a risk assessment but rarely lengthens them. In practice, the most common triggers for a non-scheduled EICR are insurance renewal, change of tenancy, and post-incident investigation after a near-miss or documented fault.

Standards and what compliance looks like
Fixed wire testing is governed by BS 7671 — the IET Wiring Regulations — which sets the technical requirements for what gets tested and to what tolerances. The legal duty to actually do the testing comes from the Electricity at Work Regulations 1989, specifically Regulation 4(2) (maintenance of electrical systems to prevent danger) and Regulation 16 (employer’s duty to ensure competent persons do the work). The inspection criteria, frequency guidance, and the format of the written report all follow IET Guidance Note 3. Maidstone Borough Council and the HSE both reference Guidance Note 3 in their compliance expectations for commercial premises.
Testing schedule and remedials
The standard test sequence is documented in BS 7671 Part 6 — inspection first, then dead tests, then live tests. We work circuit-by-circuit, isolating each in turn so the rest of the building stays live, which is what makes phased testing during business hours feasible on most Maidstone commercial premises. Once testing is done the report is drafted, including the schedule of test results, the schedule of inspections, and the list of observations. The duty-holder typically gets the certificate as a PDF within 48 hours of testing — quicker if there’s a deadline against an insurance renewal or a tenant move-in.

Why Maidstone property owners book CJA Electrical
We work with commercial clients across Maidstone 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
First contact: a five-minute call to scope the premises. We need to know roughly what the installation looks like — number of distribution boards, three-phase or single-phase, number of circuits, whether there’s any specialist equipment (server rooms, plant, kitchens) that needs handling carefully. Most quotes go out within 24 hours of the initial call. Booking: testing scheduled around your hours. Most Maidstone offices are tested outside business hours; retail units are usually done early morning or evenings; workshops and industrial premises are sometimes done in phased blocks weekend-by-weekend if the building can’t shut down at all. Reporting: PDF within 48 hours, formatted to BS 7671 Appendix 6, with the schedule of test results, schedule of inspections, and observations all in the standard format insurers and managing agents expect to see.
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 Maidstone 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
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, Maidstone 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 Maidstone. 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 Maidstone 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.
What’s a sampling EICR and is it appropriate for our building?
Sampling is when the duty-holder specifies a percentage (often 10–20%) of circuits and accessories to be tested rather than 100%. The remaining circuits are visually inspected only. The sample is documented on the report and the duty-holder accepts responsibility for the un-tested portion. Appropriate for large, low-risk premises on tight inspection cycles. For most Maidstone commercial, full testing is the right call.
Who’s legally responsible — landlord or tenant?
Depends on the lease. In a typical full-repairing-and-insuring (FRI) commercial lease the tenant carries the duty for the installation within the demise. In shorter leases the landlord usually retains the duty. For multi-tenanted buildings, the landlord normally holds the duty for shared common parts and main supply. We can read the lease with you on a quick call and clarify who needs to commission the EICR.
