Yes its a mess (probably a bit of an understatement) however are my patch there is a interesting cross section of:
established sparkies, registered for Part P, doing excellent work
established sparkies, not registered for Part P, doing excellent work
5 week wonders, registered for Part P, doing excellent work
5 week wonders, registered for Part P, learning on the job doing good work
pub sparkies who don't give a dam
builders who don't give a dam
kitchen fitters, resistered for part p, doing excellent work
kitchen fitters, resistered for part p, doing awful work
kitchen fitters, not resistered for part p, doing awful work
bathroom fitters, resistered for part p, doing excellent work
bathroom fitters, not resistered for part p, doing excellent work
bathroom fitters, resistered for part p, doing awful work
DIR'ers who have knowledge doing a reasonable job
DIY'ers who don't have a clue about electrics or part P doing awful work
Bottom line is that those who have had electrical training and knowledge, IMHO, are those who are following the regs in some shape or form, whilst other trades don't give a dam - and that is where we should all be venting our frustration.
tin hat on
PS - yes its a mess.
