i have dealt with this sort of query a few times in a previous job. unfortunately the cctv is there to protect the car park owners, not the people parking there, so it’s unlikely there will be any covering where you were parked and even if your car is visible in some footage (eg if you’re near something they want to monitor, like the entrance) it probably won’t be clear enough to show a number plate or anything else of any use. you might not even be able to tell which car is yours.
none of the queries i dealt with had any useful cctv but i think the process was that had there been any, the person could have put a request in writing to be passed to a data protection person within the company who would determine if the footage could be released (to their insurer rather than to them directly possibly?). i can’t remember the details really but i’m thinking maybe if you were trying to get the number plate of someone else’s car it would have to be requested by the police as part of an investigation?
sorry, that was boring (not half as boring as watching blurry cctv that doesn’t show anyone’s car get damaged). short answer: no
