Dont anyone make the mistake i did after being made redundant i paid myself to go on a refirgeration course . Yes you finish up with plenty of qualifications but you dont work on any systems you would find in the field.And when you try to apply for jobs no one is interested , so if you want to get into the trade dont waste your money on these courses best off trying to get an apprentiship , My problem is being 37 with mortgage and 2 kids apprentiships not the way forward .But be wary of these courses if your looking to retrain
