Clear and straight to the point. A world of difference compared to the other ISO auditing companies we have worked with. I can only recommend. Our interface, Craig Jones, was very responsive and flexible to our needs. I can only recommend them.
Oliver and Ian provided excellent customer service and guidance throughout our ISO 9001 application. With their support the whole process was very quick.
Many Thanks!

CDL have been so helpful with our application for ISO9001 and ISO14001. It would have been infinitely more difficult without their guidance.
Special thanks to Oliver and Ian for a smooth process.
Eddie and Dave have been there for us every step of the way for this process. They simplified it for us making it a lot easier and faster to gain our EN 1090. They are unbelievably knowledgeable in their areas and are always at the other end of the phone to offer guidance and advice. They organise everything for you including weld tests, audits etc which really took the pressure of ourselves. We passed with flying colours and we really couldn’t have done it without them. As a company we cannot recommend them highly enough. We look forward to working with them again in the future.
We have been working with the team at CDL for years and they are always helpful and happy to provide advise and guidance to the best of their knowledge.
I take comfort in knowing I can call on the team there at any point to discuss any queries i may have.
Fantastic service! Knowledgeable, friendly and approachable staff who helped us achieve accreditation for EN1090 structural steel.
The help and guidance of the CDL team in implementing and maintaining our ISO accreditations is top notch! They make a daunting prospect understandable and achievable. Recommended!
Excellent customer service from initial inquiry to receiving our ISO certificates. A lot cheaper than alternative quotes
