Calum Jenkins

Thank you very much for the assistance. “I attended the NDEA L4 course and found the course excellent. The structure was interesting and informative, the very experienced trainer (Muhammad) gave me the opportunity to give my views and speak openly about my experience. Over the 5 day course, Muhammad tailored the training to my level of ability and skills and I was able to really develop my energy modelling knowledge. A very refreshing approach and I took away many tips and lots of information. I am looking forward to do other courses with Quodox and wouldn't hesitate to recommend them to others. Thank you

I did a 3 day DEA course in Dec 2015. I was very happy with the way Trainer gave over the information, he was extremely knowledgeable and clear. I would highly recommend.


Many thanks for the training, Abdul made this course a breeze by explaining the points clearly. I am grateful for the response to queries and look forward to using their services for other qualifications/training. Thank you


I attended the 3 day DEA course recently and was very impressed. Our Tutor was not only an excellent trainer but he is also vastly experienced and very knowledgeable. I would highly recommend as not only during our course but even afterwards he was available for continued support whenever I needed it. Thanks to him / I am now a qualified DEA.

David Harris

I attended the 3 day DEA course and was very impressed. Abdul is an excellent trainer who is extremely knowledgeable. His teaching was methodical, understandable and generally a pleasure to be part of. He has also been available for continued support when I've needed it. Classes were small and very well run, would highly recommend it

Stewart Taylor
