Electrical installation defects
Online defects list for electrical installation work
An online defects list is provided to assist the electrical industry to correctly record defects as required by the Electricity Safety (General) Regulations 2019 on Certificates of Inspection or Audit Forms.
The Defects list can be filtered by Defect Type and key words used to search the Defect Description.

Where the electrical installation work being inspected and/or audited, does not comply with the minimum requirements of the relevant section of the Act, regulation or clause of the Standards, the defect number allocated to that particular section/regulation/clause must be identified on the Certificate of Inspection or the Audit Form.
Where a Licensed Electrical Inspector has added defects to a Certificate of Inspection and the Licensed Electrical Worker or Responsible Person wish to appeal these defects, contact ESV’s COES Manager for consideration, including all evidence to support your appeal.
ESV can delete a defect from a Certificate of Inspection if the certificate has been returned to the LEW for rectification.
Note: Defects cannot be removed from completed COES and ESV does not cancel COES that have defects identified on the Certificate of Inspection.
Electrical installations work defects
The following criteria has been utilised to allocate the selection of ‘Unsafe’ defects in the defect list.
- Immediately unsafe: the ability for a person to make contact with exposed metal that may be live or may become live when energised where only one action is
required by a person or animal to come into contact with those live parts; and,
- Any requirements of the Legislation and or Standards intended to protect persons and livestock from electric shock hazards that may arise from the use of an
An electrical installation or electrical installation work deemed unsafe by an Electrical Inspector or Electrical Auditor must be isolated from supply, or the individual circuit disconnected and made safe.
Defect documentation requirements
The description and location of each defect documented by an LEI during inspection or Auditor during an audit must be accurate, legible and in plain English.
To assist the LEI in preparing a valid defect description, the LEI should always use the text from the relevant clause or section of the document the LEI is defecting the installation on.
