For the early part of 2022 our LEV Training Courses will be operating as Webinars only with (hopefully) Face-to-face format again available from March.  Note that some courses will run  with both format options on the same dates.  See individual course pages for formats and dates.

Customer Reviews

“Bill I must thank you for a very enjoyable LEV course. I have to say that, the way you developed the information was first class – the delivery was fluent, natural – in fact it came across as extemporaneous! It was also very informative about the subject so as to enable us to undertake the practical aspects out on site. I don’t profess to be an expert in such matters – but I thought it was very well done and it’s no surprise that your pass rate is high. ( I just hope to be in that statistic!)”

“I would like to give Bill Cassells a huge shout-out. Absolutely fantastic Tutor with more knowledge in LEV training than anyone I have ever met. Just received my LEV certificates today in both P601 and P602. Without the help of Bill this probably wouldn’t have happened. Anybody thinking on doing these LEV courses, look no further than this Man. I will hopefully be doing the P604 Course at some point also.”
