Certification Process

In the first step, you discuss your company, your management system, and the goals of certification with us. On this basis, you will promptly receive a detailed and transparent offer, tailored to your individual needs.

Especially for larger certification projects, a planning meeting is a valuable opportunity to get to know your auditor as well as to develop an individual audit program for all involved areas and sites.
A pre-audit also offers the opportunity to identify potential for improvement as well as strengths of your management system in advance. Both services are optional.

The certification audit starts with a system analysis (audit stage 1) and the evaluation of your documentation, objectives, results of your management review and internal audits. During this process, we determine whether your water efficiency management system is sufficiently developed and ready for certification.
In the next step (system audit stage 2), your on-site auditor assesses the effectiveness of all management processes. In a final meeting, your auditor will provide you with a detailed presentation of the results and possible improvement potential for your company. If necessary, action plans will be agreed upon.

After the certification audit, the results are evaluated by the independent certification board of DQS. You will receive an audit report documenting the audit results. If all requirements of ISO 46001 are met, you will receive an internationally recognized certificate.

To ensure that your company continues to meet all the important criteria of the standard after the certification audit, we conduct surveillance audits on an annual basis. This provides competent support for the continuous improvement of your management system and business processes.

The certificate is valid for a maximum of three years. Recertification is carried out in good time before expiry to ensure continued compliance with the applicable standard requirements. Upon fulfillment, a new certificate is issued.


How much does ISO 46001 certification cost?

The cost of ISO 46001 certification depends on a number of factors. For example, whether you already have a certified management system plays an important role. Furthermore, the size of your company as well as the water consumption have an influence on the duration of the audit and thus on the price. We will be happy to make you an individual offer for your company or organization without obligation.
