Both very knowledgeable, bounced off each other comparing real life experiences to classroom based theory. Practice bays clean and tidy, plenty of opportunity to get hands on.

Lecturers were very detailed and explained topics really well. They were always happy to answer questions and explained how things worked. Equipment and facilities were also great, would highly recommend this course.

Course was delivered brilliantly by Lee & Gary in a fun and interactive way, the course covers everything required for 33kV switching which is necessary for progression into HV systems.

Thanks Lee and Gary! This was another great experience following the Protection course. I previously found UK Safety standards for HV Authorised Persons quite challenging, but this course provided excellent training and really built my confidence in HV safety operations. Thanks so much, Lee. See you again!
