Just completed the SIA approved Level 3 CP course with these guys, and I can't speak highly enough of them. A really professional company, with great trainers and an impressive network of specialist guest speakers with decades of experience in the top of their respective specialities that are brought in for lessons and to enhance learning on the various exercises throughout the course. The company keeps course numbers small to make sure that students are getting the best tuition with plenty of 1:1 time for all students, and offers amazing levels of support that I didn't think existed in the commercial world. I particularly enjoyed the high proportion of practical work that gave me the chance to consolidate the theory. I can't thank the Greymen enough for all of their input into my development over the past couple of weeks. Thank you guys!
