How to remove Parental control?

I've got the new installation of Virgin media with the latest kit. I'm trying to disable Parental control for watershed hours. I've gone into Parental control settings and disabled Set pin for payments, watershed recordings but can't actually see disable Parental control disable. I can add Lock Channels but can't figure out how to disable this completely. It's so annoying during the day having to enter a pin every time I scroll through the channels. Help!
