Office trunking and twin sockets in a commercial fit-out tested by CJA Electrical

For Swale 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 Sittingbourne 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 Sittingbourne 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 Sittingbourne

The standard inspection cycle for commercial premises follows IET Guidance Note 3. For most Sittingbourne 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 Sittingbourne 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 Sittingbourne property owners book CJA Electrical

CJA Electrical is based in Rochester and covers commercial work across the whole of Swale from there. Sittingbourne sits within the 30-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

Step one is a scoping call — usually 10 minutes — to establish the size and complexity of the installation. We’ll ask about the distribution board count, circuit count, three-phase vs single-phase, and any specialist equipment. From that we put a fixed-price quote together, usually within a working day. Step two is the actual testing visit, scheduled to fit around your operations. Most commercial EICRs in Sittingbourne take half a day to two days on site, depending on the installation size. We can phase the work across multiple visits if the premises can’t sustain a single block of testing. Step three is the report — a PDF within 48 hours of testing completing, with the BS 7671 standard format and all observations coded. If the report is unsatisfactory, step four is a separate remedial quote so you can plan the work to bring the installation back to compliance.

What affects the price

Pricing is transparent: a fixed price for the inspection and report, separate quoting for any remedial work. The fixed price is set after a quick scoping conversation about the installation — circuit count, board count, three-phase or single-phase, any specialist equipment to handle. What the price includes: the on-site inspection, dead and live testing, schedule of test results, BS 7671-formatted report, PDF delivery within 48 hours. What’s separate: remedial work (quoted line-by-line against the report observations), any re-testing needed after remedials are completed, and any additional reports if the duty-holder wants the original split into board-specific certificates.

FAQs

How long does a commercial EICR take?

Half a day for a small Sittingbourne 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.

Do you handle three-phase installations?

Yes. Three-phase is normal on commercial Sittingbourne 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.
