Spare bedroom ? Look at it this way, could have been a lot worse.
I can only guess but it seems to me if the insurers 'get their skates on' to estimate the claim, then you would be free to find the tradesman of your choice fairly quickly. Urgent jobs do tend to cost though, and the problem is that it may be the less well recommended that has time to drop everything and get yours done.
Unsure if you were expecting to put guests up in that room over Xmas, but my preference would be to shut the door on it, and get it done on a normal timetable rather than rush it.
