CDL Group Ltd Reviews 

I have worked closely with Ian from CDL Group for a number of months. He has been a huge support in addressing the areas of ISO I needed to address for my company. Without his support, it would have been a lot harder and taken much longer. He has sat with me on video calls explaining things I didn't fully understand or had questions about. Ian showed me much patience and also offered much support via email when I had brief questions. His responses were always thorough and timely. The quality of support our company has received has been exactly what we hoped for.

Ian was very easy to talk to and always available via over phone or email. Also provided constructive detailed feedback of our IMS system

Achieving ISO 9001-2015 accreditation is an ongoing multi staff operation.
Professional guidance provided by CDL -Group was exceptional and the whole team were appreciative.

Great team who are organised and efficient in their audits. Thank you CDL group.

Craig and the rest of the team dealt with our application very quickly and have provided a great amount of support throughout the process. We definitely recommend.

I dealt with Ian and Craig and found them both to be very Knowledgeable and helpful.

They provided a comprehensive guide to achieving and maintaining an ISO standard.

Excellent service! Friendly and knowledgable staff who made our ISO accreditation painless. Thank you.

We have been using CDL for a number of years now and I must say that the service is excellent. The implementation of our ISO9001 & ISO27001 systems was a daunting task at the beginning, but with the expert knowledge and guidance from the CDL team we were able to make this a much simpler process. The regular audits from the team have helped our company stay compliant and we appreciate the straight forward feedback that we receive to help strengthen processes that help our business to grow. I can't recommend CDL highly enough.

I have only positive things to say about CDL. From start to finish they are excellent across the board. The team are professional, approachable and genuinely supportive throughout the audit process.
Eddie, Ian and Ann in particular go above and beyond to help. They take the time to explain things clearly, are always responsive, and make what can be a stressful process feel straightforward and manageable.
Their knowledge and experience really show, and you can tell they care about their clients and the quality of the service they provide.
I would have no hesitation in recommending CDL to anyone looking for ISO certification audits.

Brilliant, very responsive and did exactly what was required in order to complete deliverables.

The CDL team provide an efficient, helpful and supportive ISO certification service. They are always responsive and available for ad hoc queries during the year and I wouldn't hesitate to recommend them.

From the very beginning, the level of guidance we received was outstanding. The team provided clear, actionable orientation and was remarkably quick to respond to every query we had. What truly set them apart was their efficiency; all initial documentation was delivered ahead of schedule, allowing us to move forward with total confidence.

We contacted CDL to assist in gaining our BSEN 1090 Accreditation.

Going in not knowing a great deal about the spec, the team could not have been more upfront and helpful.

From coding our welders, training our RWC's and helping us create a manageable 1090 system, CDL were with us every step of the way and their after sales support has been fantastic.

I could not recommend them more.

We recently worked with CDL Group as our external ISO auditors, and I've been impressed with their service.
Their approach was thorough and professional throughout. The audit was carried out fairly, and the feedback on minor non-conformities and opportunities for improvement was clear and well-explained.
What stood out was the balance they held us to the standard while also helping us see where our systems could be stronger. The feedback was practical and useful, not a tick-box exercise.
I would recommend CDL Group to any organisation looking for a reliable and knowledgeable ISO auditing provider.

Hassle free, quick and fully professional. Strongly recommended.

Ian helped a lot in getting credditation for our company. He made things a lot simpler for us and had our ISO certs back in a matter of a few days!

I worked with CDL Group for over 4 years and it was a great experience. Very professional, great support and commitment. Always available to providence guidance and help.

Friendly, knowledgable staff, felt comfortable right away and was able to settle into the welding.
Highly recommend using these guys.

Great experience getting our ISO 9001, 14001, 45001 recertification quickly and easily! We have been in contact with Ian throughout, who is always available if we have any questions and gets back to us so quickly. Thank you!

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.
