I am in the same situation, only owner of a 46 sq/m flat working as game artist. I have been billed last month for over 3000£ for works that had been carried out before I bought my flat (which I am investigating in, as my property is never listed in the breakdown they sent me), regarding the Heating system, and now I just received a notice for more planned works regarding the heating?!?! How I will be able to afford that?
Did you go to the meeting? how did that go?
