Professional Auditors

Viridis Auditors is a new branch of Viridis Consultants, set up to dedicate greater resources and focus to providing value to our audit clients. Viridis Auditors specialise in management system audits across a range of industries, with a niche in the water sector.

Auditing is a vital role in all management systems and we take our role seriously. ISO standards refer to the Plan Do Check Act and cycle of continual improvement. We tailor our audits to provide not only levels of compliance, but also pragmatic opportunities for improvement.

Our Services

Our Services

We specialise in third-party regulatory auditing, but can also provide internal audits and gap analyses to assist in preparing for an up-coming audit.


The most common way to engage our services is through a tendering process for a particular audit. However, this can be inefficient in time and cost. For those clients that want high performance, we offer auditing service agreements whereby we can manage the entire audit calendar, or we can hone in on certain aspects.
