The reason it's costing money when ringing it for New Year and other dates didn't is that the renovations were planned around those dates. The clapper has been removed, and would have to be replaced, but the belfry floor was removed on January 2nd, to allow the longest possible time before the bell needed to ring again for Armistice Day in November, and can't be replaced in a hurry without considerable expense. Also, replacing the floor now would stop the renovations that required its removal, which would also have a major cost in making the whole project overrun.
