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

Commercial EICRs cover the same fundamentals as domestic — BS 7671:2018+A2:2022 inspection and circuit-level testing — but the scope typically extends further. Distribution boards (often more than one in a commercial premises), socket circuits with significant equipment loading, lighting circuits for shop floors or office spaces, dedicated circuits for plant and machinery, emergency lighting feeds, fire alarm interface circuits. Findings coded per the standard. Unsatisfactory results need remedying promptly to maintain compliance under the Electricity at Work Regulations.

When you need this in Canterbury

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

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

  1. Initial conversation — premises type, size, distribution board count, operating hours 2. Same-day fixed quote 3. Booking arranged around your operating hours where possible 4. On-site inspection — usually in a single visit, sometimes split for larger premises 5. Report PDF supplied within 48 hours 6. Remedial work quoted alongside any unsatisfactory findings; expedited where business-critical

What affects the price

Commercial EICR pricing is per premises and depends on size, distribution board count, accessibility, and operating-hours constraints. Canterbury commercial property varies — small high-street retail is straightforward, multi-floor offices with multiple boards take longer. Same-day fixed quote on receipt of the premises details. No deposit, payment on certificate.

FAQs

Can you handle EICR alongside other commercial electrical work?

Yes. Where the inspection identifies remedial work, we quote alongside the report and can carry out the work directly — single point of contact from inspection through to clean re-issued certificate. For larger commercial projects (refits, new layouts, additional distribution), we work alongside other trades on a programmed basis. See domestic electrical for the broader scope of work we cover.

What documentation do you supply for our compliance file?

Standard three-part EICR PDF — the EICR form with overall outcome, the schedule of inspection, and the schedule of test results. For commercial duty-holders we’ll often supply a brief covering memo summarising the scope of the inspection and any follow-on actions required, useful for the H&S audit trail or for handing over to a lease counterparty.

How often does my office in Canterbury need an EICR?

Industry guidance under the Electricity at Work Regulations 1989 typically suggests every five years for offices and retail premises. Workshops or premises with higher fault loading (kitchens, plant rooms, anywhere with significant heat or moisture) may need three-yearly inspection. The Electricity at Work Regulations require the duty-holder to maintain the installation in a safe condition; the EICR is the standard evidence of that ongoing duty.

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.
