Fully labelled domestic consumer unit after EICR testing

Commercial EICR work for offices, retail premises, and small workshops in Dover. Under the Electricity at Work Regulations 1989, the duty-holder (employer or building owner) is legally required to ensure the installation is maintained in a safe condition; the EICR is the standard documentary evidence of that ongoing duty. CJA Electrical handles commercial inspections across Dover and the wider Dover area.

What an EICR involves for Commercial

Standard EICR scope adapted for commercial premises — every distribution board inspected and circuit-tested, every accessible accessory checked, earthing and bonding verified. Special attention to circuits with significant load (server rooms, kitchen equipment, workshop plant) where fault loading is higher than domestic norms. Output is the standard EICR PDF in three parts (form, schedule of inspection, schedule of test results), with C1, C2, C3, FI codes against any findings.

When you need this in Dover

Common commercial EICR triggers in Dover: - Five-yearly cycle on offices and retail (or three-yearly on workshops) - Insurance renewal where the insurer has asked for evidence of inspection - Lease renewal — incoming tenant or landlord wants current safety paperwork - Building purchase — pre-acquisition due diligence on commercial property - Major refit or change of use — new layout needs fresh certificate - Power quality issues, repeated tripping, or a near-miss event - Health and Safety inspection requesting evidence of EaWR compliance

What the report contains

Commercial EICRs come back as the standard three-part PDF — form, schedule of inspection, schedule of test results. For larger premises with multiple distribution boards, the schedule of test results is typically tabulated per board so it’s clear which circuits sit where. Unsatisfactory reports come with a remedial-work quote attached. Under EaWR 1989, remedial works on commercial property need to be carried out promptly to maintain the duty-holder’s compliance — there’s no fixed 28-day timeline like the PRS regs, but “reasonably practicable” is the standard.

How the inspection runs

The commercial flow: Conversation about the premises — what kind of business, how many distribution boards, when’s a quiet time for the inspection. Quote out same-day. Inspection scheduled outside peak hours where possible. Visit. Report inside 48 hours. Remedials, if needed, quoted with the report. Where the business has continuous operation (24/7 retail or hospitality), we’ll work with the duty-holder on a phased inspection that minimises disruption.

What affects the price

No standard rate card for commercial work — premises vary too much. Quote on receipt of scope (premises type, size, distribution arrangement, operating hours) and the price is fixed at that point. Single invoice, payment on certificate.

FAQs

Do I need an EICR for insurance renewal?

Increasingly, yes. Many commercial insurers now ask for evidence of recent electrical inspection at renewal, particularly for premises with significant equipment loading, kitchens, or workshop activity. A current satisfactory EICR satisfies the question without further follow-up. It rarely changes the premium meaningfully but it does take a question off the renewal forms.

Can the inspection happen outside business hours?

Where the business operating hours allow, yes — early morning, evening, or weekend slots are often the easiest answer. Where the business operates continuously, we’ll work with the duty-holder on a phased inspection that tests circuits in turn outside their peak-load periods. Quote reflects whichever timing works.

What happens if my commercial premises fails the EICR?

An unsatisfactory commercial EICR identifies remedial work needed under EaWR 1989 to maintain the installation safely. The duty-holder is legally required to address the findings within a reasonably practicable timeframe — typically faster than the standard 28-day window for PRS landlord work because of the operational implications. We quote the remedials alongside the report and expedite where the findings are business-critical.

Do I need separate EICR work on emergency lighting and fire alarms?

The EICR covers the supply circuits feeding emergency lighting and fire alarm systems but not the systems themselves. Fire alarm certification under BS 5839-1 (for larger systems) and emergency lighting testing under BS 5266 are separate specialist regimes. We can do the emergency lighting installation and testing — see the emergency lighting page — but BS 5839-1 fire alarm work for larger commercial systems is typically a specialist’s job.

Will the inspection cause much disruption to my business?

Power is off briefly on each circuit during testing — typically 15-30 minutes per circuit — but the rest of the premises stays live throughout. Scheduling the inspection during a quieter trading period or outside peak hours minimises the impact. For premises that genuinely can’t lose any power during business hours, we’ll arrange the inspection out of hours.
