Commercial EICR in Longfield

For Dartford business owners, building managers, and commercial landlords, the EICR is the piece of paper that closes the loop on the Electricity at Work Regulations 1989. CJA Electrical does the inspection, the test schedule, and (separately, if needed) the remedial work to clear observations. Most Longfield commercial jobs are scheduled outside trading hours so the testing doesn’t disrupt the business.

What Commercial EICR actually is

The technical name for what most Longfield 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 Longfield

There’s no single statutory cycle for commercial EICRs the way there is for domestic landlord property — the duty-holder works to IET Guidance Note 3 and to whatever the insurer’s policy schedule requires. Most policy schedules across Dartford reference five-year intervals as standard, with shorter cycles where the building has higher inherent risk. What we see most often in Longfield is the renewal trigger — the insurer asks for a current certificate at the policy anniversary, the building’s last EICR is more than five years old, and we get called in to bring it back into date. Other common triggers: a new tenant on the lease, a CDM-flagged fit-out completion, a refurbished consumer unit that needs documenting against the new circuits.

Standards and what compliance looks like

BS 7671 is the technical standard for the work itself — what “satisfactory” looks like, what gets tested, the tolerances on each test, the format of the report. The Electricity at Work Regulations 1989 is the law that says the duty-holder must keep the installation safe and provides the framework for prosecution if they don’t. Together they’re the framework Longfield duty-holders work within. The current edition of BS 7671 is the 18th Edition with Amendment 2 (2022); any EICR signed off after January 2023 should reference that. Reports referring to older editions of BS 7671 are still technically valid for the cycle they were issued in but should be re-tested to current standards on the next inspection.

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 Longfield property owners book CJA Electrical

We work with commercial clients across Longfield 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 Longfield 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

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 Longfield 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 Longfield 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 Longfield 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.
