who we are

LinquaCert is a Swiss certification body and a specialized service provider for ISO certifications according to the recognized international standards ISO 17100, ISO 18587 and ISO 9001.

LinquaCert as a company is an independent Swiss cooperative based in Zurich (Switzerland) and therefore your ideal partner. Our company was registered with the commercial register office on November 12, 2003. We are certified as an accreditation body in accordance with the ISO/IEC standard 17021.

We have a partnership with TÜV Süd for ISO 9001 certification together with our own auditors as well as for requests for further audits.

On our websites we provide you with general information about the services we offer. These do not replace advice on an audit. If you are interested in certification according to ISO 17100 or 18587, we recommend that you contact us using our contact form, email or telephone.

We will respond to you immediately and make you a non-binding offer for certification.

Feedback is important to us

Close contact with our customers is particularly important to us, both in initial communication and in discussions during the certification process. Feedback is important to us and an essential part of our quality management.

If you have any suggestions, you can contact our sales team at any time. As an ISO-17021 certified company, we ensure that all feedback is processed and answered in a standardized process. In the event of a dispute, we always strive to find an amicable solution that is customer-friendly. A long-lasting customer relationship is more important to us than a short-term successful legal dispute. As a Swiss company, we are subject to Swiss commercial law as well as agreements with other countries and trading areas.

Our certification, headed by Markus Kukla, will be happy to assist you with any questions you may have about audits and certificates issued. It also acts as an independent unit in the audit and ensures that a neutral authority evaluates the certifications.
