I think these courses should be stopped or at least sanctioned a bit better, I've met several of these 12 week course plumbers straight out of the starting blocks, and it aint pretty. The courses fill their head full of (false) confidence by doing workshop exercises, which every trained plumber will know that the workshop is a little different to whats on the job, then the balls something up, and it's not their fault, it's these damn courses!! I think it should all be reverted back to 4 year apprenticeships, and if there isn't enough apprenticeships around, you'll just have to wait. All these courses do is make less jobs for the trained, less money for the trained and a damn-site less public confidence in the plumber of today.
Don't get me wrong if you do the course and you've made it, fair play and good luck but it's the blokes who don't make it I feel sorry for!!
You can make 50K+ a year, I do......but I also work 70hrs+ a week as a subby!!
Not the best industry atm!!
