Inspection & Testing Documentation

Following the completion of all new electrical installation work or additional work to an existing installation, the installation must be inspected and tested and an installation certificate issued and signed by a competent person or persons. Specifically, the person or persons responsible for the following activities must be identified:

Person(s) responsible for design

Person responsible for construction

Person responsible for inspection.

The ‘competent person’ must have a sound knowledge of the work undertaken, be fully versed in the inspection and testing procedures contained in BS 7671 (IEE Regulations) employ adequate testing equipment.

A certificate, inspection and test results should be issued to those ordering the work in the format given in the following pages.
