He comes once a year and asks to see a list of all the jobs I have carried out in the 12 months since he was last here, he then asks to see my domestic certs and asks for proof they were put through building control, he then picks anything from 2-4 jobs at random and asks to go there, whilst there he makes me re-test certain parts of the circuits and checks the results as well as looking at the jobs to ensure they are up to scratch and I also get the usual looking at insurance H&S manual etc etc, the visit last a half day and usually is pretty useful actually as I get to listen to the bull they are thinking of employing to us over the next 12 month period, new rules and bull they want us to adhere to, if they see anything they are not happy with you have to put it right and write to them within 30 days to confirm any minor defects have been carried out, they sometimes go back to check you have done so, luckily I don't get too much of that and usually the visit is successful, however as an approved contractor it is a little more intense from a DI scheme.
I presume you are Nic approved, I'm only domestic now and it's pretty much the same on the inspection except that you tell them which two jobs you are going to show them.
i did once ask how they know that all my jobs are to standard rather than just the two jobs I show them. He seem to think no one would do that!!
as for Napit I am shocked that they operate in that way, I really can't imagine an inspector just turning up in the middle of a job, what happens if you haven't got the time to give him and I'm sure the builder/client would be annoyed if you stop working so that some one can poke around the job.
do you have to register every single job before you start it, more paper work.
I always thought all the bodies preformed the same way.
My thoughts on Part P is either the whole house is covered or just get rid of it.
