Electrical Safety Inspections - Commercial

To protect people and property every electrical installation should be inspected and tested periodically to ensure it remains in safe condition for continued use. 

Electrical wiring and the associated accessories (e.g. sockets, fuse boards, light fittings)  deteriorate due to age and wear & tear; this can lead to risk of potentially fatal electric shock or fire. 

A periodic inspection is recommended every 5 years for most commercial premises - some premises require more frequent inspection and testing (see the table below). We regularly carry out these important safety inspections and provide our clients with a full written report known as an Electrical Installation Condition Report (or E.I.C.R).

Why have an Electrical Installation Condition Report?

  • In a commercial environment the landlord and employer have a duty of care over employees and the premises. The Electricity at Work Regulations requires that an electrical installation should be adequately maintained in order to prevent danger as far as reasonably practicable. An E.I.C.R. provides evidence that these safety check have been carried out and provides a prioritised plan for any remedial work

  • Insurance companies are increasingly insisting on periodic inspection and testing of the electrical installation in insured premises

  • New premises - purchase or lease. Confirm that the electrical installation is safe and in suitable conditions for your needs when purchasing or leasing premises.

  • Fire or Flood - If your property has experience major damage it is wise to get the electrical installation checked and the results properly documented. This then provides a prioritised plan for any remedial work

What does an Electrical Safety Inspection Involve?

Similar to a vehicles MOT, an Electrical Installation Condition Report documents the condition of your electrical installation and gives you a clear, concise, safety verdict (Satisfactory or Unsatisfactory) as well as a summary of the overall condition. In addition the report also details any defects found and tells you how serious they may be.


  • The inspection & testing usually involves minimal disruption to the premises. 
  • The procedure starts with walking around all rooms and areas to make a visual inspection of the electrical installation.
  • We then carry out a detailed set of tests at the distribution board(s) and at sockets, light fittings, and other electrical outlets throughout the premises. 
  • Depending on the type of premises, we often carry out the testing stage of the work out-of-hours to minimise any disruption to your operations, as it does require power to be turned off for short periods. 
  • Once our on-site work is complete, we take our results back to the office to assess all the measurements and compile your report.

Please call us to discuss your requirements and we will provide a fixed price quotation for a periodic inspection & testing services tailored to your needs.

What does the report contain?

The report documents any defects that are found, ranging from immediately dangerous faults to minor faults and recommendations for safety improvements. We will usually provide a competitive written quotation for any such remedial work; however our reports are always written in sufficient detail that should you wish to, you can easily use them to obtain alternative quotations from other electrical contractors.
