bwca and the impact43 courses are both fairly informative advice from experienced window cleaners which i think is invaluable both david and craig who ran the courses when i attended were really nice guys, if you have spare 150quid to go on bwca id say go on it its quite motivational as for impact nvq its free bar your own time and effort
I think you should re-word that.
Having the words "free" and "bar" next to each other might attract the wrong types

I did a couple of the BWCA courses and the NVQ2 by Impact43.
All of them contained info that I will possibly never need and also, all could have filled gaps in what I know.
This is not a criticism. All the courses were OK for what they were. They were either one day ones so I wouldn't expect them to cover any more than basics plus a few extras or, as in the NVQ2, spread over several sessions so covered a fair bit of ground but no more than you would expect to cover in that time frame. I felt the NVQ2 course did start at a very basic level but it should be remembered that it must also include people who could have a borderline literacy problem so that they can get the help they need to complete the course.
