I'd be very interested to hear about your assessment with NAPIT. They've already out performed NICEIC by actually providing some meaningful communication.
Hope it goes well.
So I had NAPIT assessment this morning. A thoroughly pleasant chap turned up who turned out to be the senior assessor for my postcode region. For new applicants he said they try and send senior assessors but can't always. His opening line was "This is first assessment - I'm here to help not to trip you up".
So two main sections - paperwork and technical.
The paperwork was like any other assessment, 18th edition certificate, 2391 details, calibration certificate, insurance check, complaints log, H&S policy.
Then technical which comprised questions then a job visit.
A few questions about safe isolation, do I have a proving unit (yes), do you have to use one (no as long as known live source is used before and after). He commented many say "yes" and he's looking for evidence people understand and sensibly apply the regs, not sheep.
A look at a recent EIC I'd done - do any measurements jump out at me? (an r2 suspiciously low compared to r1 and rn on a RFC) - what would you expect it to be (x1.66 if normal T+E) - where do you get that from (ratios of csa). Why did I think it was like that? (quite a lot is in conduit with 2.5mm cpc)
What would you expect the R1+R2 to be on that rfc ( divided by 4 rule)
Then went to look at a job which was a new CU install, demonstrated a Zdb and PSCC. Demonstrated safe isolation and an rn reading. We then had a chat about tails in a cavity - it was one of those where service cabinets were outside on garage wall and CU is high up on garage wall. with tails in the middle. On this one he agreed there was plenty of space in the cavity, but a nudge to watch out for that as some assessors go to town on that and if they declare it unsafe he can't overrule that in his senior capacity even if he privately thinks its OTT. It was fair comment.
We then had a general chat about several things assessors were picking up on a lot. Some are apparently too pedantic about continuous professional development - and advised to keep a log of any situation where I get advice, even occasional forum posts! Another common one is no SPD and no risk assessment, and make sure I either fit one or do RA. Also make sure I have at least one commercial job to look at next year.
After that a quick demo of NAPIT Mobile software (which I didn't purchase at this point) and he was done.
So in my case at least I didn't find it a difficult experience at all.
