RCD and loop impedance testing in progress on a domestic circuit

Commercial EICR scope sits under the Electricity at Work Regulations 1989 rather than the 2020 PRS regulations — same testing standard (BS 7671:2018+A2:2022) but a different legal driver. Inspection frequency depends on the environment: typical offices and retail every five years, workshops every three, anywhere with significant heat or moisture loading sometimes annually.

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 Gillingham

Beyond the routine cycle, commercial EICR demand spikes around two events: insurance renewal (where insurers increasingly ask for current EICR evidence) and lease changeover (where incoming tenants or landlords want clean baseline documentation). Both are predictable and worth scheduling proactively rather than scrambling for a slot when the renewal date is two weeks away.

What the report contains

Standard three-part EICR PDF deliverable. For premises with significant fire alarm or emergency lighting infrastructure, the EICR covers the feed circuits but the alarm/lighting maintenance regime itself is separate. We’ll flag where additional specialist inspection (BS 5839-1 fire alarm, BS 5266 emergency lighting) is recommended.

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

Pricing depends on the premises. Variables: number of distribution boards, total circuit count, accessibility of distribution and accessory locations, and any constraints around operating hours. Larger premises with multiple boards take longer than a single-board high-street unit. Same-day fixed quote, no deposit, fixed price agreed before the visit.

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.
