CDL Group Ltd Reviews 

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.

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

I will be using for further clients

This is our second year dealing with the CDL Group and as last year their professionalism, guidance and knowledge is second to none. Our Auditor Ian is firm but fair and helped us tailor a process that ensured continued development in line with ISO standards

Brilliant and professional service from start to finish. The team are prompt and helpful and this has made the process easy to understand and action.

We have been using CDL for a number of years for ISO certification and find the staff during audits and at administration stage to be very helpful ensuring a hassle free experience. Would recommend for any one requiring ISO certification.

We recently achieved our EN1090 EXC2 certification, and we couldn’t have done it without the team at CDL Group. From start to finish, the process was handled with a high level of professionalism and technical expertise.
Kerrith was fantastic at the outset, helping us demystify the initial process and always being available to answer our questions, no matter how small.
Eddie walked us through our new FPC manual with impressive clarity. He was concise and ensured we fully understood exactly how our business needed to operate day-to-day to remain compliant.
The RWC course was excellently presented and easy to digest. Following the course, David provided invaluable support to ensure we were 100% audit-ready and capable of managing our welding processes moving forward.
The Weld Procedure Qualifications and weld tests provided by CDL were professional and easy to follow, making a complex part of the certification feel manageable.
Thanks to their guidance, we passed our audit with confidence. We will definitely be using CDL Group to maintain our welding qualifications as our business continues to grow. Highly recommended for any fabrication business looking for a smooth path to certification!

Excellent experience working with Ian and the team. Professional, knowledgeable, and extremely thorough throughout the compliance process. Communication was clear, support was practical, and everything was handled efficiently. Highly recommended for any business needing reliable compliance guidance.

I made contact with Kerrith a few weeks ago to book in some welder qualification renewals, he was really helpful and had us booked in within the hour with a date that suited our busy schedule.
We had Paul in today to witness the tests and he was amazing from start to finish.
The Welders always dread test day but he made the whole process stress free and relaxed for them whilst explaining exactly what they needed to do.
It always helps when the Inspector is an ex welder who has been there and done it, which all of CDL's inspectors have.
I can't recommend CDL enough!

We recently used CDL Group for our ISO audit and the service was outstanding from start to finish. The team was professional, knowledgeable, and incredibly supportive throughout the entire process.

We felt fully supported at every stage and couldn’t be happier with the outcome.

Highly recommended 10 out 10 — Amazing service and exceptional expertise!

We’ve been using the services of CDL Group for over six years now and the support has consistently been excellent. The whole process is always smooth, well organised and completely hassle-free. Craig and Ian keep in regular contact by phone and email, ensuring everything runs efficiently and that our requirements are met. I wouldn’t hesitate to recommend them.

We’ve had an excellent experience working with CDL Group, and I wouldn’t hesitate to recommend them to any business looking for certification, testing, or professional support.
From the very first conversation, Craig Jones (Business Development Manager) was absolutely brilliant. He was friendly, knowledgeable, and took the time to properly understand our business and what we needed. Nothing ever felt rushed or sales-driven — just honest advice, clear explanations, and great communication throughout.
The audit process itself was handled by Ian Jones, who was equally impressive. Ian was extremely professional, very approachable, and incredibly quick to respond to any questions we had. His guidance was clear and practical, and he made what could have been a stressful process feel straightforward and well organised.
Overall communication from CDL Group was first-class — emails and calls were answered promptly, timelines were clear, and we always knew exactly where we stood. The team genuinely want you to succeed, not just tick boxes.
The level of technical knowledge, professionalism, and support throughout the entire process was outstanding. Everything was handled efficiently, with a real focus on helping us achieve the right outcome for our business.
We will absolutely be using CDL Group again in the future and would highly recommend them to any business considering their services.

As a business newly working toward ISO 9001 certification, we couldn’t have asked for a better auditing partner. The entire process was incredibly smooth from start to finish.
The auditors were professional, approachable, and made what initially felt like a daunting journey surprisingly straightforward.
What really stood out was the quality of the feedback. Everything was clearly explained, constructive, and genuinely helpful in strengthening our quality management system. Their insight gave us confidence that we’re building a strong foundation for long‑term compliance and continuous improvement.
Highly recommend to any organisation—especially those new to ISO 9001—looking for a supportive and thorough auditing experience.

I have worked with the CDL team for the past three years to establish and embed ISO 9001, ISO 14001, and ISO 45001 within our business. Throughout this time, the team has consistently provided a friendly, supportive, and highly professional service.

The auditors demonstrate a strong understanding of our business and apply the standards in a proportionate, value-adding way. Feedback and advisories from external audits are clear, practical, and constructive, supporting continual improvement rather than simple compliance.

Overall, CDL’s approach provides assurance while genuinely supporting continuous improvement across the business.

I booked a couple of tests before Christmas I had great communication from the team and felt welcome when I arrived to their facility in Wales I would recommend to anybody looking to gain certification for their welding or employers looking to train their workforce!

As a start-up company ISO certification can be a daunting task. With the assistance of CDL Group Ltd and especially Craig we have managed to secure our ISO9001. Looking forward to working closely together with you moving forward.

We had a very positive experience working with CDL Group on our ISO journey. Craig was phenomenal throughout the process—always responsive, accommodating, and proactive in supporting our requirements. Thanks to his support, we achieved ISO 14001 and ISO 20000 certifications for Shivom Consultancy Limited promptly and on time.

In parallel, CDL also supported A&A Digital Tech (AADT) in achieving new ISO 9001, ISO 14001, and ISO 45001 certifications, all delivered with the same level of efficiency and professionalism.

Ian, the Lead Auditor, was extremely professional and a pleasure to work with. He provided clear guidance, practical direction, and conducted the audit in a collaborative and constructive manner, which made the experience both efficient and reassuring.

We are continuing our journey with CDL Group for additional ISO standards and ongoing renewals, and would highly recommend them to any organisation looking for a knowledgeable, responsive, and dependable ISO partner.

Fast, efficient and good customer service. Well done

Kerrith’s demonstration of of the two Bipol video scopes we were interested in was comprehensive and detailed, all features were explained and we were able to use that information to experiment practically with the devices.
All questions were answered, plus many more that we hadn’t thought of.
