More likely 9pm as that's the latest the queues close at Scarefest/fireworks. They don't want to close too late as they still have the run the rides till the queues are empty.
Yeah Towers has never opened beyond 9pm due to local restrictions. Pretty sure they have a limit on the number of 9pm closes as well (negotiable with the council). I suspect the aim is to have the rides shut down by 11pm.
