Which certificates do I need?

If you need a certificate it will be stated in our vacancy. Safety comes first for jobs in construction, technology and industry. That is why you always need a safety certificate in these sectors, a so-called VCA. You will receive this diploma after a course and exam. A VVL certificate is often mandatory in construction and industry. This shows that you can move goods and materials safely and responsibly. A forklift certificate can be useful in logistics or horticulture. Did you see a nice vacancy, but haven’t you got the requested certificates? No problem! At Concreeto we are happy to help you achieve this.
