My boyfriend has worked in the same job for 14 years, and at the age of 30 he has decided he would like to learn a trade before its too late. What is the best way for him to go about this? He would like to do some sort of plumbing course on a part-time basis, poss evenings. But where does he start? Will be need a diploma 1st then a NVQ? HELP!.xx
