Private parking firms and residents car park

[DaGuv]

I'm the owner of a tenanted flat in a development of 46 flats. The management company want to start using ukcps to run the car park. There has never really been an issue with parking and bays are not allocated to flats. They are going to start a trial soon with ukcps controlling the parking with 1 permit per flat and 1 visitor pass per flat. I have concerns about the legatlity of this. The car park has no marked bays as such since the lines have worn out. I think the problem is that there a few fuss pots who live there who like to moan a lot. What are my options for stopping the trial etc. Thanks
