Commercial EICR in Istead Rise

CJA Electrical does commercial EICR and fixed wire testing across Istead Rise and the wider Gravesham 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

A commercial EICR is a periodic inspection and test of the fixed wiring in a commercial premises — the distribution board, sub-circuits, sockets, lighting, and fixed equipment connections. It’s the same fundamental process as a domestic EICR, but typically covers larger installations, three-phase supplies, and the kind of building services (emergency lighting interface, fire alarm interface, plant equipment) that don’t appear in residential. The output is a written report against BS 7671 with observation codes (C1, C2, C3, FI) on anything that doesn’t meet the regulations, plus a schedule of test results documenting what was actually measured. The duty-holder uses the report to plan remedial work and demonstrate compliance.

When you need Commercial EICR in Istead Rise

The standard inspection cycle for commercial premises follows IET Guidance Note 3. For most Istead Rise 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 Istead Rise 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 Gravesham local authority, and every commercial landlord we’ve worked with.

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 Istead Rise 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 Istead Rise property owners book CJA Electrical

CJA Electrical is based in Rochester and covers commercial work across the whole of Gravesham from there. Istead Rise sits within the 28-minute working radius — close enough that scheduling around your trading hours and getting back for remedial work is a non-issue. The work is done by someone qualified to City & Guilds 2391 (Inspection & Testing) and 2382 (18th Edition Wiring Regulations), using calibrated test equipment, with reports produced in the standard BS 7671 format your insurer and managing agent recognise. No subcontracting — the person on site is the person signing the certificate.

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 Istead Rise 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 Istead Rise 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’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 Istead Rise 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.

How long does a commercial EICR take?

Half a day for a small Istead Rise office (single board, ~20 circuits) up to two or three days for a multi-board industrial unit. Premises that need phased testing across weekends will take longer in calendar time but the same total testing hours. We give a realistic estimate at quoting stage based on the circuit count and access conditions.

What happens if the report comes back unsatisfactory?

Unsatisfactory just means the inspection has flagged C1 or C2 observations — items that need putting right to bring the installation back to compliance. The report lists each item, and CJA Electrical can quote separately for the remedial work. Once the remedials are done, the affected circuits are re-tested and a fresh, satisfactory certificate is issued.

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.
