CDL Group Ltd Omdömen 

Our experience with CDL Group Limited during the certification process for Koolmax Group Limited was professional and well-structured. CDL Group Limited conducted the assessment and successfully issued ISO 9001 (Quality Management Systems) and ISO 14005 (Environmental Management Systems – phased implementation guidance) certifications.

Throughout the process, their team demonstrated a strong understanding of ISO standards and provided clear guidance on the documentation, internal procedures, and compliance requirements necessary to meet certification criteria. Communication was consistent, and the audit stages were explained in a straightforward manner, which helped our team prepare effectively.

The auditors were thorough but constructive, focusing not only on compliance but also on identifying areas where operational processes could be improved. This approach made the certification process more valuable than simply obtaining the certificates, as it supported the development of stronger internal systems within Koolmax Group Limited.

Overall, CDL Group Limited delivered an efficient and supportive certification process. Their structured auditing approach and professional conduct helped ensure that Koolmax Group Limited achieved ISO 9001 and ISO 14005 certification with confidence. We would consider them a reliable certification body for organisations seeking to implement recognised management system standards.

Having spoken with Craig and set up the ISO 9001 & ISO 14001 within an hour, speedy service and great assistance with the audit team.

We had Paul in today to witness the tests and he was amazing from start to finish.

It always helps when the Inspector is an ex welder who has been there and done it, which all of CDL's inspectors have.
