Simon,
Sorry mate but if you submit that job for your Elecsa assessment without carrying out some urgent remedial work you are going to get a rough ride, a really rough ride. They are very keen on the correct IP ratings for CU's and of course it must be properly secure. I know you say it has come off the wall since you did the work, and I dont know you or what your normal standard of work is like. But if I were to give my humble opinion of that example i would say it looks very amateur, and DIY standard. I am just trying to give you the benefit of my experience with Elecsa assessments, I have had 5. Minor misdemeanours will be dealt with by you being given advice from the assessor, but submit anything sloppy, be it work example, poorly completed certs etc and you will get crucified, and your £475 is down the bog. Dont get me wrong, they are working electricians just like us, and want to help, but as with anything first impressions count.
My last assessment was last week, and in general conversation he was telling me that due to the downturn Elecsa are getting a large amount of new applicants, and a lot of them are being referred due to their lack of experience and knowledge. i dont know what your experience etc is, but if you are not 100% ready to be assessed than save your money. I have no wish to offend you or your ability, but you will need to do better to get through.
Good luck,
Howard
