I hate to say I told you so. If you want an answer ask him how deep to dig an 'ole.

You paid your solicitor to answer these questions. Problem is, he is only really interested in making sure he doesn't get sued so although he will act to protect both of you, don't think you are his first interest.
First thing to do is find out if there is a certificate you don't know about. If not.....
It will almost certainly be quicker and better for the solicitor to advise you to insure, and who knows he might even have an arrangement with an insurer to get it all sorted out.
If you want to know the ins and outs of this indemnity insurance you should look at the policy documents in the first instance. They will tell you the exclusions. Basically the insurance company isn't going to insure you if they think they will pay out so the exclusions will be relatively obvious.
1) The won't insure any work done within the past 12 months. This is not a coincidence, 12 months is a legal limit which limits the councils ability to enforce. So the insurance is becoming worthless.
2) They won't insure if you have started 'negotiations' with the council to 'formalise' the work done. They don't want to be on the hook to fix things when it's likely the council will be round to find things to fix.
3) They won't insure if a surveyor has identified the building work as a risk. Now any surveyor, once he finds out the work hasn't been passed by the council, will identify that work as a risk. In fact, most surveyors nowadays identify everything as a risk. So again the insurance is becoming worthless. (If the surveyor identifies a massive defect in the work then the council can enforce if it's considered dangerous after 12 months but that's another matter)
However getting you to buy insurance lets all the solicitors tick their boxes and will give the buyer peace of mind - though that's probably misguided but that's not your problem. You just want to flog the place.
Now I have bought properties which have had building work done without building control certificates but that might just be me, you cannot expect all buyers to act that way. So if this old work gets flagged up then you probably have to get insurance, but from what you have said so far, there isn't a reason why the insurance company won't take your money. Just do not enter into any negotiations with the council to regularise ( or more likely complete, as they already inspected by the sounds of it ) the work done ten or more years ago. And keep quiet about it to everybody else thogh you will have to declare to your solicitor. Nobody else !
