Thanks very much guys the most I'll probably be in Thailand at any one time will be the 90 days before flying back to the UK to check on my business then fly back again so the Non O sounds just right.
Thanks Tod. I do fly back and forth as I have a business back home and proving what I earn isn't an issue it's just I like to keep my bank accounts private lol. So the Non o visa may be a better option for me at the moment.
