Business Quality Mark Responsible Cleaning shows that responsible cleaning is not only on paper, but also visible on the work floor.1nergiek is the first cleaning company in the Netherlands with this quality mark at company level.

Working safely is a given at 1nergiek. But not every assignment or every part of our services requires the same way of organizing and managing. That is why we have both VCA* and VCA**.
VCA* mainly focuses on the safe execution and control of our own work. It shows that safety, health and environment (SHE) are properly arranged on the work floor and that employees know how to perform their work safely.
VCA** goes a step further. In addition to safe execution, this certification sets more extensive requirements for the way safety within the organization is organized, managed and safeguarded. Think of project-based work, structural risk analysis, management responsibility and the supervision of other people's work.
Because our services are broad. A large part of our cleaning colleagues carry out regular cleaning tasks. In that area, it is mainly about performing their own work safely and responsibly.
Within our Specialist Cleaning, we also carry out work where the risks, circumstances and management can be more complex. In that case, not only safe working is important, but also how we organize safety in advance, control risks, define responsibilities and supervise. That is why both certifications suit 1nergiek:
VCA* – we work safely.
VCA** – we organize and manage safety structurally.
So we do not choose one standard approach, but the safety level that matches our work. Because whether it is daily cleaning or specialist cleaning: every colleague must be able to do their work safely and return home safely at the end of the work day.

Discover whether we are a good match. We listen to your wishes and situation and openly and honestly discuss what we can mean for you with our cleaning services.
