There must be arrangements made for initiating reports of wear and tear from users of the premises. This should be supplemented by routine checks. The frequency of these checks will depend entirely upon the nature of the premises. Routine checks would typically include: |
|||

| Defects reports | All previously reported defects have been rectified | ||
| Inspection of | Look for: Breakages Wear & deterioration Signs of over heating Missing parts (covers, screws) Loose fixings Confirm: Switchgear accessibility (no obstructions) Doors of enclosures are secure Adequate labelling in place |
||
| Operation of | Operate: Switchgear (where reasonable) Equipment – switch on & off Including RCD’s (using test button) |
||
