I did compex 01-04. English is not my first language. I got extra support, a bit of extra explonation, extra advice. All of this was super helpful. The instructors were very knowlagable, passionate and well tempered. I failed one of the units but I passed it second time.

I had an excellent experience training with EPIT Aberdeen. The instructors were incredibly knowledgeable, professional, and clearly passionate about what they do. The facilities and equipment are top-quality, and the training was delivered in a way that was both practical and engaging. Everything was explained thoroughly, with real-world examples that made the content easy to understand and apply. The staff were friendly and supportive throughout, creating a really positive learning environment. I left feeling confident, well-prepared, and genuinely impressed with the standard of training. Highly recommend EPIT Aberdeen to anyone looking for high-quality, industry-leading courses.

Done the CompEx Ex01-Ex04 with Mike and Dodd, and they were both excellent! They both broke things down and made them easier to understand, as well as being genuinely good people who you can have a normal conversation and laugh with!

An absolutely brilliant training and test facility that made the dreaded "Compex Refresher" course, a far more enjoyable and beneficial experience. From the great training material to the very knowledgeable instructors, it all helped to teach us about the new practices and standards in Compex and I certainly left knowing more than I did when I walk through the door Monday morning. Thanks to the all staff! 5*
