The South West School of NDT specialises in providing training and examination services in the methods of Non-Destructive Testing, and associated technologies. The SWS holds independent accreditation from the British Institute of NDT and UKNANDTB.


The South West School of NDT is part of the Minton, Treharne & Davies Group ( a family owned testing company established in Cardiff in the 1890’s. Always keen to remain ahead of client needs, when NDT evolved from the universities in the 1940’s, the group developed capability in this exciting new field. Our enthusiasm for NDT spread in to sharing our knowledge and the SWS opened its doors to students over 40 years ago in Cardiff. We continue to grow our technology base, and expertise and have never lost our enthusiasm for the world of NDT and continue to invest in new technologies, and equipment to enhance the services we deliver to our clients. Over 2019/2020 the SWS has moved from its ‘old’ location in the Pentwyn area of Cardiff to a purpose build training school at MTD’s Longwood Drive site in Cardiff’s Forest Farm nature reserve. We think there is nothing like it in the world!





Our approved training courses provide the knowledge based needed for successful qualification in NDT inspection methods, in a supportive learning environment.

Offering central certification (PCN, ISO 9712) examinations and Employer Based Scheme Examinations (EN4179, NAS410 and SNT-TC-1A), the SWS can support your qualification needs in all NDT methods.
