Right so guys i am looking at taking this course as i am from the UK and wondered if anyone was in the electrician trade and the ups and downs of it?

I may be asking on the wrong forum here so sorry if none of you know! After searching online i know that the City and Guilds offer the Electrotechnical Services NVQ qualification but i am just no sure how to obtain it, is it done on the job?

Thanks in advance guys.
