Highly recommended

We recently engaged with CDL to acquire welding certification, dealing with CDL as an overall was great experience. Timely and helpful communications during the preparation of the tests and supportive during the testing.

I would highly recommend CDL if you are in need of any weld certification.

RWC Course

Everyone at CDL Group in Newtown was great, I fully recommend anyone to use their services in the future as Dave the tutor was very knowledgable and accommodating to all that took part.

Marvellous, knowledgable and role specific

My employer signed me up to this course and having spent twelve years working in the Nuclear and Petrochemical sectors in Non Destructive Testing and coding welders in a previous job, to being appointed as the company Welding Co-Ordinator, this course is a worthwhile one.
The tutor was very knowledgeable and provided a specialist insight to to the specifics of the RWC role.
This course provided me with a top up on visual welding defects and the weldability of specific metals. This was worthwhile as my PCN L2 VT had lapsed a couple of years ago.
I was impressed at how tailored the course was to the specific role at my company within the Aerospace sector.
I am thoroughly looking forward to the onsite GAP Analysis that the tutor will be providing for our company.
I would highly recommend this course for both beginners and those more advanced in welding and welding related operations.

Pain-free 14001 certification

As a company with a mature ISO9001 quality system and accreditation under 4 further ISO standards, we appreciate the thorough yet swift service by Craig and Ian. The 14001 desktop audit was completed in 5 working days and the certificate issued promptly. The procedure documents and record templates provided are a great help for us in collating the relevant data for the next audit. We felt in safe and competent hands.

CDL service and Bipol equipment

From first contact CDL, and specifically Kerrith that I spoke with, were professional and exceptionally helpful. A period of testing of a Bipol videoscope allowed a highly informed purchasing decision to be made after experiencing the quality of the product in its real world application. The communication and support from Kerrith means I am confident of the continued quality service CDL will provide.

Outstanding Service and Professionalism

We had an excellent experience with CDL for our welder qualifications and new procedures to EN and AWS. From start to finish, the team was professional, knowledgeable, and incredibly supportive. They made the entire testing process straightforward and stress-free from booking to final documentation. No query is to small and the really go out of the way to help with any problems you may face. We will be using CDL for all our welding and testing requirements and cant recommend them enough.

They supplied exactly what we needed.

Our company contacted the CDL Group with quite a specific requirement. Their representative came on site to realise our needs and offer solutions. In my opinion they went over and above our expectations, finding us the right product, a Bipol Pro B videoscope, and in a very short space of time. I wouldn't hesitate to contact them again should we need their expertise again.

Consistently excellent

We've had a consistently excellent experience with CDL for our ISO audits. Our dealings are always thorough, practical and professional. Our main auditor, Ian Jones, always brings a balanced and insightful approach with constructive feedback and no unnecessary red tape. Ann in Accounts is also always helpful in coordinating everything smoothly and keeping us on track.
