I am sure Diane Abbott mean't carillon. The Express, that bastion of brexiter ignorance and ill-education, famously published the headline:

"Carillon collapse hits shares of rivals Galliford Try and Balfour Beatty"

I suspect that the only way a carillon collapse could do this would be to fall on their directors. Though this might always send the shares up of course.

How much is a carillon? There are various sites from manufacturers and restorers, none seem to give prices. The answer seems to be that if you have to ask, you can't afford one.

All of which would be way over the heads of the readers of the Express of course.
