Anything that involves altering a circuit physically or altering its design needs to be certified. So not all the work you do needs a cert but you probably do a couple of quick tests when you get to a job to for example change over a socket. So pretty much every job required to some degree inspection and testingI'm not sure what you mean that 'all work needs certifying'' because that isn't the case (I don't certify all work I do).
