Its a trick route here where sparkys are concerned, they dont want chancers getting in, they take great pride in there tradies here thats why the pay is good, hence thats why its a tricky processs, I know this for sure !. Are you in Adelaide or uk as your status says nottingham that can put massive hurdles in your way if your not already here.first, its going to cost, but see it as an investment. 2nd be sure you have relevent uk quals bs7671 means nothing here on its own. 3rd it may take time I mean a couple of years !!, but lets start at the beginning. If the tradie is the lead aplicant then they will have been assesed one way or another, which means you are 50 to 90% there as you have to have proof of basic quals to qualify, if you are qualified with an apprentiship then this is all you need tra will verify this and your home and dry for about $2000, you will need to do aussy wiring rules when you get here. If there's a descrepancy in the apprentiship or qualifications its still not imposible, skills sa will put you on a course at peer at no cost however you must be working in the industry and have been assed by vetasses prior, this will take about 3 months and consist of several visits to peer and exams, also you must complete a years e-profile (a record of type and period of work completed) this may be reduced for retrospective proof of experience in australia, it has to be signed by a company manager or superviser consistently to be valid.
failing these directions you may sign up with a reconised traning organisation (RTO) and re sit all the modules but as an adult aprentice with provable quals from the uk these will be reduced by sitting an entrance exam which will assess your knowage and weak points. This route will cost you, but again if your working you should get citb registerd for finalcial assitance, some places may require you to be a registred apprentice.
barring the tra which provides a equivelent certificate, you will receive a level 3 cert in electrotecnology and can be used anywhere worldwide.
