Multifunction tester measuring end-to-end resistance on a ring final circuit

For commercial premises in Ashford, the EICR is documentary evidence the duty-holder is meeting their obligations under the Electricity at Work Regulations 1989. The inspection itself is the standard BS 7671 test; what changes is the regulatory framing and the typical inspection frequency. CJA Electrical works with small-business owners, office managers, and landlords of commercial premises across Ashford.

What an EICR involves for Commercial

The technical inspection follows BS 7671:2018+A2:2022 — the same regulations that apply to domestic installations. The inspection scope covers the consumer unit (or distribution board), every accessible accessory, the supply route, and circuit-level testing for continuity, insulation resistance, polarity, earth fault loop impedance, and RCD operation. Findings get coded C1, C2, C3, FI per the standard. Commercial-specific elements: emergency lighting circuit verification, fire alarm circuit feeds, dedicated socket circuits for IT and equipment loads — all in scope where they apply.

When you need this in Ashford

Common commercial EICR triggers in Ashford: - 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

Reports come back as a single PDF in standard EICR format. Plain-English cover summary where useful for the duty-holder; technical schedules behind for the H&S audit trail. Failed reports include the remedial quote alongside, and we’ll typically prioritise commercial remedials because of the operational impact (a circuit that’s failing inspection is one that’s heading for a tripping event during business hours).

How the inspection runs

What it looks like in practice: Property scope conversation — premises type, size, distribution arrangement. Quote and appointment options out the same day. Visit arranged around your operating hours. Inspection visit (single day for most office and small retail; multi-visit for larger premises). Report PDF inside 48 hours of the final visit.

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

What standards apply to commercial EICRs?

The same testing standard as domestic — BS 7671:2018+A2:2022 — applies to fixed electrical installations regardless of whether the premises is residential or commercial. What differs is the regulatory framing: commercial EICRs sit under the Electricity at Work Regulations 1989, with the duty-holder (typically the employer or building owner) legally required to maintain the installation safely.

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.
