You should be aware that businesses which keep records of customers' details are required to register as data users with the Information Commissioner's Office.

just reading this from one of D.A.'s posts and wondered if anyone was registered with them?

I asked the commissioner's office a few years ago, when I was involved with a different business. They told me then that I didn't need to worry about it, as they consider invoicing and the like, standard business practice. From what I gathered, they are looking for people who keep general info on file to assist in sales, etc.

Of course, things may have changed since then...
