Start with the premises and its operation
Commercial installations vary widely, from a small office with a few circuits to premises with multiple distribution boards and machinery. The purpose of the inspection, the layout and the nature of the business all affect the scope. Identify who manages the building and who can authorise access or isolation. If areas are shared with tenants, there may be different responsibilities for common parts and occupied spaces. Explain those boundaries before an appointment is arranged. A useful report starts with a clear understanding of what is to be assessed, not with assumptions that every part of a site is under the same control.
Periodic intervals are not one universal rule
The appropriate interval between inspections depends on the installation, its use, environmental conditions, maintenance and relevant requirements. Previous reports may recommend a next inspection date. An insurer, lease or other arrangement may also set expectations that should be checked by the person responsible for the premises. Do not assume that a domestic rental interval automatically applies to every workplace. The report and any limitations should be read alongside the actual building use. If the occupancy or activities have changed significantly, discuss whether the previous assessment and inspection arrangements are still appropriate.
Planning electrical isolation
Testing may require circuits or boards to be isolated. Before work is agreed, identify computers, refrigeration, alarms, production equipment and other systems that need careful planning. This does not mean all of them will necessarily be affected, but their operation should not be left to chance. Access to distribution equipment must be clear and the responsible people available. Some tasks may be organised in stages; the practicality depends on the site and the inspection extent. Tell Sean about operating hours and busy periods so that the arrangements can be discussed without promising that every test is possible without interruption.
Records for property managers and insurers
An EICR records findings within its stated scope and provides a basis for decisions about remedial action. Keep previous reports, certificates for alterations and any maintenance information available. These records can help explain how the installation has developed, though they do not replace current testing. If an insurer requests a particular document, clarify exactly what is needed rather than treating all electrical certificates as equivalent. Reports should be passed to those responsible for acting on the observations. A document marked unsatisfactory needs attention; it is not simply evidence that an inspection appointment took place.
Observations, limitations and follow-up
Classification codes communicate the urgency of issues found. Dangerous or potentially dangerous conditions need an appropriate response, and further investigation may be needed where an issue cannot be resolved within the inspection. Access restrictions and agreed limitations should be apparent in the report. Repairs, alterations or further tests may form a separate programme of work. Sean also offers commercial electrical installation services, so distribution, lighting and related remedial requirements can be discussed. The important distinction is between identifying a condition and documenting the work used to address it.
Information to include when enquiring
Send the site postcode, the building use and any existing report or certificate details you can provide. Mention the approximate number of distribution boards if known, access restrictions, occupancy and equipment that needs planning around. Avoid opening electrical covers to gather information. Photographs of externally visible labels can help where safe. If portable equipment also needs checking, ask about PAT testing as a separate service. A commercial inspection enquiry can then be shaped around what you actually need rather than a domestic booking description that leaves important site details out.
Make the installation boundary explicit
In a shared building, equipment may be maintained by different organisations. Before an inspection, identify which boards and circuits belong within your responsibility and who provides access to common areas. A report for a tenant’s office does not automatically assess a landlord’s entire distribution arrangement. Explain what you need the document to cover and whether an insurer has requested a specific extent. Keep the instructions with the site records so the report can be understood by someone who did not arrange the appointment. That clarity is especially valuable when premises managers or tenants change.
After a change of occupancy
A different business or revised layout can change the demands and use of an electrical installation. Earlier records remain useful, but they should not be assumed to describe every later alteration. Share details of new equipment, changed rooms and work carried out since the last report. This helps establish what needs assessing and whether the available records are complete. The person managing the premises should keep certificates for additions rather than relying only on an old condition report.
