I actually wish I had more experience as I see how valuable it is. All these qualifications aren't much it you don't have the confidence from experience to apply it. I wish I had the experience before the qualifications, not the other way around. It seems like you would be more than capable of offering the services whilst studying, but I'm not sure how that would stand with the ICB. I suppose just contact them and see what they say. Perhaps you could spend the time preparing your business while you are studying instead of aftually offering the services? If you know what kind of business you want and how you want to run it, what pricing mode you want to use, have a website etc etc before you actually start practicing, that is half the job done. The bookkeeping is the easy bit! Then you won't feel like you have wasted your time while you are studying and the ICB won't have the opportunity to frown upon you providing services that you are not yet qualified on paper to offer. Now, I could be a way off the mark here, but that is my understanding from reading posts and checking out the ICB practice licence terms and conditions. I expect to find out for sure in the next few days while I submit my practice licence request.
Whatever you decide, good luck with your new venture. I look forward to hear how you get on.
