Yes, easily.

Need at least the name or business name for that to work it seems.
IF you have the knowledge on how to do it presumably.
Yes you do need a name to start the enquiry and to pay a subscription to 192.com for the full service and registration with someone like "Experian" to use a credit reference company if you want a credit history. Registration costs £££s and you have to jump through a number of legal hoops to gain registration as well as satisfying them as to why you would be using their services.
BTW I can also CRB check people if I need to but again only for legitimate business purposes (i.e. if someone is paying me to find details for a legitimate reason)
Neither is something I would piss about with as I could forfeit my licence if I was caught so no I don't do "casual" enquiries.
Obviously you need a name and ideally an approximate location or date of birth to get started but it takes only a few minutes to gain all sorts of info if you are a registered user.
PS You don't need to be an IT Buff to find people but a knowledge of the systems helps.
