Firstly be careful what you discuss with the Council, it might invalidate a potential indemnity policy. Whilst they are generally a waste of time and money some mortgage lenders insist on them so you could be making life very difficult for yourself.
Secondly, you can now go back to vendor and ask him about the 1987 application. Was it a full plans application and was it approved or was it a building notice?
With regard to site inspections I'm not sure what the "no entries of inspections" means. Is this just that the person was looking on the central register which just details the applications or does their system log each site inspection? Whenever I have had to check inspection records on older applications it is a matter of going into the Council offices and looking at the old archives, usually on microfiche or scanned and looking at the hand written inspection reports on the file. You would expect that if they went to the trouble to submit an application they would have had at least some of the inspections carried out.
