Overall S4 course and course materials are good. Learned switching programs and operation are helpful to work on field. ( commissioning of the Generator and BESS system)

Course was good, but probably could have been finished in less than a week. However, got a good understanding from it. Both tutors spot on, good rapport and very knowledgable.

Was a bit disappointed regarding course handouts, these where giving on previous courses and now they cost and additional £25 per person after spending £6000 on the courses, also the exercise hand outs are no longer giving and you have to go and look at the single line diagrams in the exercise hall which are incorrect. I heard whispers that you are losing business to Pass, I'd maybe address the above points and bring the standards back to where they were on previous courses I have attended. Overall though still a great training facility.
