No, I wouldn't have expected there to have been. The building control system isn't set up with diy'ers in mind, so don't assume they've been remiss by not holding your hand through the whole process. They'll usually help and advise - if you'd asked when inspections need to be done, they'd have happily told you. IME Tradesmen are no help either here when you are project-managaing, and subcontract pros for notifiable work - if they aren't personally responsible for getting BCO sign-off as part of the job, then they don't give a monkeys... several times I've found myself almost having to physically restrain builders etc "...for crissakes don't cover that lintel till the BCO has been round later"
Are you sure? Unfortunately from what you've described, as Roger has pointed out, it looks like it's very much down to you that the required inspection wasn't carried out at first-fix stage, ie when the wiring was exposed. What will you do if the council end up telling you that you must re-expose everything?
I don't know what the answer is, but all I'm saying is think very carefully before holding up your hands.
