I have the following qualifications, C&G 2365 Level 3 and 17th Edition completed in July 2014. I have worked in installations for the last six years and had all work signed off by my boss. I would like to think about going for the C&G testing certificate 2391-52. Little unclear about what I need to start this course. Do I need to get the final amendment on my 17th that came out in 2015 and then get the one day course on the 18th Edition to be able to start the testing certificate? I have never done the NVQ 3 so would this need to be done before I can start the testing certificate? I have got to do all of this off my own back as I am now out of work due to covid. Any help or advice would be helpful, thanks
