I'm a bookkeeper, and you haven't quite got the definition correct for a "Not for Profit". It's about the legal structure of your business, take look here if you want to read a bit more about it:If I go back and answer No to question 6 (as above) then Question 7 gives a list of 34 reasons in answering 'None' to those, Question 8 checks that the information held is for 'Self Administration, Accounts or Records, advertising, marketing and public relations (in connection with your own business activity)' which they are so no requirement.
It's a fun game
