If you run a business or look after a commercial property, the electrics can be easy to overlook until something trips, a tenant asks for paperwork or an insurer wants a current report. By then, finding the last inspection and arranging access can become another job on an already busy list.
A commercial Electrical Installation Condition Report (EICR) gives you a clearer starting point. It records the condition of the fixed installation and helps you decide what needs attention. This guide explains the duties, timing, scope and records for commercial premises in England, including Yorkshire, so you can plan inspection and testing with confidence.
At a glance

Businesses must manage electrical safety. The Electricity at Work Regulations 1989 require systems to be maintained, as necessary, to prevent danger so far as reasonably practicable. An EICR is a recognised way to assess the fixed installation, but these Regulations do not prescribe one universal commercial EICR interval. See HSE guidance on the Regulations.
In practice, you need to arrange suitable inspection and maintenance, understand what the report covers and act on its findings. Your electrician can help turn those responsibilities into a workable plan for the premises.
It helps to separate three things when deciding what your premises need.
Legal duties
Legal duties concern preventing danger from electrical systems and work activities. An EICR supports that work; it is not a blanket guarantee of compliance with every duty that applies to your business.
Technical standard
BS 7671, the IET Wiring Regulations, provides the technical standard for assessing electrical installations. It is not itself an Act of Parliament.
Contract and site requirements
Contractual or site requirements may add conditions. Check your lease, insurance policy, licence and any sector-specific requirements for the exact wording, deadlines and evidence expected.
Worth knowing: Rules for rented homes do not automatically apply to commercial premises. If your building contains both homes and business space, ask for advice covering each part and check the responsibilities under your lease.
Start with the next inspection date on your previous report. Ask the electrician whether it still suits the premises, particularly if the building’s use or condition has changed. HSE’s guidance explains that maintenance frequency depends on the circumstances and relevant experience.
We recommend discussing the following before agreeing an inspection date:
In practice: For example, a business moving into a unit with no reliable electrical records should ask for a condition assessment before assuming the existing installation suits its planned use. An office changing into a workshop also needs a conversation about the new demands on the system. These are reasons to seek advice, rather than automatic rules for a particular interval.
Don’t wait: If you have noticed overheating, repeated tripping or damaged electrical equipment, seek competent advice promptly. Do not wait for the routine inspection date or open equipment to investigate it yourself.
Unsure when your premises were last tested? Speak to Calder Electrical with the previous report, if available, and a brief description of the building’s use, or call 0800 612 3001.
An EICR combines inspection and testing of the fixed electrical installation. Depending on the agreed scope, it considers distribution equipment, circuits, wiring, switches, sockets, lighting, earthing and bonding, protective measures, identification and signs of damage or deterioration. The inspector records observations and assesses suitability for continued use. Electrical Safety First explains periodic inspection and testing.
Read the scope as carefully as the overall result. The IET EICR model forms distinguish the parts inspected and tested from agreed and operational limitations, with reasons recorded.
Before booking, ask which buildings, distribution boards, circuits and areas are included. Identify locked rooms, equipment that cannot readily be shut down and areas needing special access. Ask how any proposed sampling or limitations will affect the conclusions, and whether additional work would be needed to obtain a useful assessment.
In practice: For example, a report covering the main office does not automatically assess a separately supplied warehouse. If a critical area is excluded, agree how it will be assessed rather than treating the whole site as covered.
An EICR is not the same service as portable appliance testing, a fire risk assessment or an energy survey. Do not assume it includes a full functional test of fire alarms, emergency lighting, machinery or specialist systems. Confirm those requirements separately. Thermal imaging may also be useful in an agreed inspection programme, but it should not be assumed to be included in every EICR.
Calder provides commercial electrical inspection and testing. Discuss the installation and any additional services you need so the quotation covers the intended work.
In an owner-occupied business, deciding who coordinates the work may be straightforward. In rented or shared premises, the landlord, tenant and employer should clarify who controls and maintains each part of the installation. Duties depend on the circumstances and matters within each party’s control; commissioning a contractor does not make the underlying safety responsibilities disappear. HSE’s safe working guidance explains dutyholder responsibilities and competent electrical work.
Tip: We recommend agreeing in writing who will book the inspection, provide access and approve any repairs. Check the lease and obtain advice if responsibility is unclear.
Use an inspector competent in periodic inspection and testing for the type of installation involved. Ask about relevant experience, the proposed scope, reporting and how urgent findings will be communicated. For a complex site, experience of similar installations matters as well as the quoted price.
HSE says maintenance and test records can help demonstrate compliance and monitor condition, although record keeping is not itself a legal requirement under the Electricity at Work Regulations. Separate contractual or other applicable requirements may still require particular records.
We recommend keeping one accessible electrical file for each premises, containing:
Keep the original report and subsequent certificates together so the next electrician can follow the installation’s history.
Planning access and shutdowns early helps keep the inspection useful and disruption manageable. Before work starts:
Your role: Let the electrical contractor plan safe isolation and testing. Your role is to provide information, coordinate access and make decisions about the premises, not to remove covers or carry out electrical tests.
C1 means danger requiring immediate action; C2 means a potentially dangerous condition needing urgent repair. C3 recommends an improvement, while FI advises further investigation. On the current IET Amendment 4 model form, C1 and C2 make the result unsatisfactory; C3 and FI do not themselves affect the overall assessment. An FI recommendation still needs prompt investigation. See Electrical Safety First’s Best Practice Guide 4.
Ask the inspector which reporting edition was used, particularly when reviewing an older report. Agree the repairs or investigation needed and when they should happen. There is no blanket residential repair deadline that applies to every commercial finding.
Worth knowing: A satisfactory report is a condition assessment within its stated scope, not permission to ignore later faults or changes. Continue your maintenance arrangements and review them when the premises change.
Ask the inspector to identify the edition of BS 7671 used for the inspection and explain any findings that relate to changes in the standard. The IET edition checker gives the current position.
An installation complying with an earlier edition is not automatically unsafe merely because the standard has changed. Its actual condition and any risks identified need competent assessment.
No. An EICR assesses an existing installation’s condition. An Electrical Installation Certificate relates to installation work, while a Minor Works Certificate applies to appropriate smaller work. Keep relevant certificates alongside the condition report; they serve different purposes.
There is no universal five-year requirement in the Electricity at Work Regulations. Obtain a suitable recommendation for the installation and check any separate requirements applying to your premises. Do not extend a shorter recommended interval without competent advice.
Some inspection and testing requires isolation. Agree shutdowns with the contractor before the visit, particularly where refrigeration, IT or production equipment is involved. The extent and duration depend on the installation and scope.
No. Appliance testing and assessment of the fixed installation address different parts of electrical safety. Confirm what is covered by each service and how they fit your maintenance programme.
The quotation depends on the installation, circuit count, access, records, testing scope and working arrangements. Ask for a site-specific quote that explains what is included and whether remedial work is priced separately. A generic domestic price is not a reliable guide for commercial premises.
