We check that all work complies with Swiss working standards (WV-CH). We cover all costs for these inspections during normal working hours.
We will periodically require you, as the owner of a system, to provide us with a new proof of safety (SiNa). Depending on the potential hazard, this period may be one, three, five or 10 years, or 20 years for residential buildings.
Before your proof of safety can be issued, you must hire an independent inspection company or an accredited inspection body to carry out the inspection, note any defects and – after these defects have been removed by an electrical installer – issue your proof of safety.
The original version of the proof of safety will remain in your possession. A copy will be sent to us.
When you hire a licensed electrical installation company to carry out electrical installations, the work is completed with a final inspection and the proof of safety (SiNa). This documentation is also issued by the electrical installation company.
For electrical installations with an inspection interval of less than 20 years – such as offices, shops, workshops, etc. – you as the owner are responsible for carrying out an additional acceptance inspection within six months of approval of the electrical installation work. For this inspection, you can hire an independent inspection company or an accredited inspection body, which will also provide you with an additional proof of safety (SiNa).
The original version of the proof of safety will remain in your possession. A copy will be sent to us.
We randomly inspect a portion of the proof of safety documents (SiNa) we receive. If there are no defects, we are responsible for covering the cost of these inspections. If we do find defects, we will charge the owner for the costs of the inspection.
