My current house - privately owned - had filthy beyond cleaning stair carpet.
I ripped it out.
Then lived with bare stairs and landing for... FIVE YEARS until I could afford to complete other dirty work and afford a carpet.
Plenty of people live with ugly stuff due to money 
You fucked up tiling over the asbestos tile floor. (and yes, I know exactly the foooring you mean)
You were 22 and didn’t know much about DIY and didn’t google. And you were probably all enthusiastic about getting your own place.
If you said ‘AIBU to so annoyed that I was naïve and 22 and paying for it now” then I’d say “cheer up chick, easily done”.
But you’re not. You’re not accepting that the council did nothing wrong, and that the problem is of your own making.
And your double standards are astounding, that you now don’t want the council checking what you want to do next.
They could actually save you money with the site visit, by stopping you from doing something else that will cost you money later.
Again: stop blaming the council, and chill your beans with your complaints about having to pay until that’s actually the situation
