Commercial EICR in Whitstable
Commercial EICR and fixed wire testing in Whitstable — Electricity at Work Regulations 1989 compliance across Canterbury.
CJA Electrical does commercial EICR and fixed wire testing across Whitstable and the wider Canterbury 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 Whitstable
The standard inspection cycle for commercial premises follows IET Guidance Note 3. For most Whitstable 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 Whitstable where a sale is in progress and the buyer’s surveyor has flagged the electrics for further investigation.

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 Whitstable 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
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 Whitstable 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 Whitstable property owners book CJA Electrical
We work with commercial clients across Whitstable 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 Whitstable 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 Whitstable 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 Whitstable 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 Whitstable 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 Whitstable 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, Canterbury City Council, and any future buyer’s surveyor will expect to see.
