UK law places duties on those responsible for electrical systems at work. The Electricity at Work Regulations 1989 set out health and safety requirements regarding electricity at work, and HSE guidance focuses on the duty to prevent danger through safe systems and maintenance.
For business owners, landlords of commercial premises, facilities managers, and duty holders, this typically means:
An EICR is not named as the only way to meet your legal duties, but it is a widely used method to document condition, risks, and remedial priorities, especially for fixed wiring systems.

A commercial EICR (Electrical Installation Condition Report) is an inspection and testing process for the fixed electrical installation—distribution boards, protective devices, circuits, and fixed accessories. It records the condition of the installation and highlights non-compliances or safety issues, helping determine suitability for continued use.
A proper EICR typically considers:
There is no single universal legal interval for every commercial premises. HSE guidance and industry commentary commonly describe commercial inspection frequency as risk-based—based on the environment, usage, condition, and competent advice.
That said, many businesses and landlords work to common planning intervals (often around five years for offices/retail as a baseline, shorter for higher-risk environments), and insurers or lease terms can require more frequent testing.
EICR reports commonly use observation codes to prioritise action. The important commercial point is not the code labels themselves—it’s the decision-making that follows:
A good commercial electrician does more than hand over a report. You should receive a clear explanation of findings, practical options, and a remediation plan that matches business constraints and risk.

Portable Appliance Testing is commonly used as shorthand for checking portable and plug-in electrical equipment. HSE guidance makes two commercial points that matter:
A sensible approach matches your environment and equipment mix. Offices and retail sites often benefit from a combined plan: user checks, formal visual inspections, and targeted testing on items with higher wear or higher risk.
Fault finding is the structured process of diagnosing electrical problems and tracing them back to a root cause. Commercial faults often present as:
A commercial fault finding job should start with context: what changed, what loads run when it fails, what protective device trips, and how critical the affected circuit is. That leads to a methodical diagnostic process and clear fix options.
Commercial electrics can become “quietly outdated” as businesses add equipment, change layouts, install new lighting, or introduce EV charging. Upgrades are often needed when:
Common commercial upgrades include distribution board improvements, better circuit protection, new circuits for equipment, and rewiring or partial rewiring in problem areas.

Lighting is one of the fastest ways to improve a commercial space’s usability and operating cost profile. For businesses, lighting changes are rarely cosmetic only. They often connect to:
Common lighting projects include LED upgrades, new fittings for refurbishments, external/security lighting, and improved zoning and switching for better control.

Workplace EV charging is becoming a practical requirement for many sites—staff recruitment, fleet transition plans, visitor expectations, and corporate sustainability goals all play a role. A commercial EV installation should consider:
Some electrical problems can wait for a planned booking. Others can’t—especially when safety is compromised or operations are halted.
Common reasons businesses request urgent attendance:
Commercial electrical needs differ depending on how a building is used. Electric11 supports a mix of local commercial environments, such as:
Offices and professional services
Typically focused on safe distribution, reliable sockets, lighting comfort, and sensible PAT maintenance.
Retail units and salons
Often require lighting improvements, additional circuits, signage feeds, and quick resolution of faults to avoid lost trading time.
Hospitality and leisure
Frequently needs careful scheduling around opening hours, robust fault response, and attention to public-facing safety.
Workshops and light industrial
Often higher loads and more demanding environments, where inspection planning and capacity upgrades matter more.
Commercial landlords and managed properties
Typically driven by EICR documentation, remedial work, and smooth coordination around tenants and access.
Commercial clients value clarity. A simple, repeatable process makes projects run smoother:
When choosing a commercial electrician in Wymondham, look for:
Tripping circuits in the afternoon or at peak load
Next step: fault finding, plus a look at load patterns and protective device suitability.
Office refurbishment adding more desks and equipment
Next step: circuit review and capacity planning, possibly additional circuits and protection.
New tenant moving into a commercial unit
Next step: EICR review and any remedial work, plus targeted upgrades.
Retail lighting feels dim or uneven, customers don’t see product well
Next step: lighting assessment and LED upgrade plan.
Workshop adds equipment and power tools, sockets struggle or extension leads multiply
Next step: add proper circuits and distribution points, reduce reliance on temporary connections.

If you’re responsible for a business premises, retail unit, workshop, or managed commercial property, these FAQs cover the most common questions around EICRs, PAT testing, fault finding, and workplace EV charging—so you can plan the right next step with less disruption.
Request a free commercial quoteCommercial EICR frequency is usually risk-based rather than one fixed legal interval. The right schedule depends on your site type (office, retail, hospitality, workshop/light industrial), operating hours, environment (heat, moisture, dust), installation age/condition, and any insurer or lease requirements. Many businesses use 5 years as a planning baseline for lower-risk spaces, with shorter intervals for higher-risk or higher-load environments based on competent advice.
A commercial EICR assesses the condition of fixed wiring and key safety elements such as distribution boards, protective devices, circuits, earthing and bonding, and fixed accessories relevant to the site. You receive an Electrical Installation Condition Report documenting observations, any non-compliances, and recommended remedial priorities, helping you demonstrate inspection and maintenance records for duty-of-care needs.
Annual PAT testing is not automatically required for every workplace item in low-risk environments. What matters is maintaining equipment to prevent danger, using a plan matched to your risk profile. Many businesses use a mix of user checks, formal visual inspections, and targeted testing for higher-wear or higher-risk items (for example, frequently moved equipment, tools, or appliances used in tougher environments).
Common triggers include load changes at peak operating times, moisture ingress, nuisance tripping after refurb work, faults in equipment connected to the circuit, and insulation issues on older wiring. A structured commercial fault-find starts with context (what changed, when it fails, which protective device trips, and how critical the circuit is), followed by methodical testing to identify the root cause and present clear repair or upgrade options to reduce downtime.
A commercial EV install should start with supply capacity and headroom, then factor in load management and future expansion. It also needs practical location planning (parking flow, accessibility, cable runs), plus appropriate protection and isolation with site-specific safety considerations. You should also expect the right documentation and a support plan for ongoing operation.
