example, my shower stopped working, landlord sent an odd job man to replace it,
not impressed so complained that a sparky should have at least checked it, so out comes the letting agents electrician, nice bloke i spoke to him as i was awaiting my niceic at the time,he was an old lag, time served,with his own firm couple of apprentices etc. and later worked with him. but all he did was check that the connections were good in the shower... dont need a cert.as its like for like he said as he left. now if that was me as a dommy i would have at least checked the bonding, non evident, and the IR, and recommended fitting an rcbo, he didnt even look at the fusebox ! experienced yes, assuming definately, i went on a rewire job as he was short handed, minimum amount of power and lighting outlets,and didnt put protection over notched joist, despite my suggestion, put smokes on rcd lighting circuit and so on, all he was interested in was getting offsite asap with the cash, i was reminded of Harry Enfields, 'loads of money , splish splash splosh, loads of dosh.'
