I haven't been through the BTWEA but have a helped a family member with the short term enterprise allowance which is similar requirements. They won't laugh at you but you need to have some sort of a business plan in place, preferably have done a start your own business course and yes you must get approval before you start your business so any work you have done to date is market research, remember that - market research only. Business plan was not complicated, I think it was all on their form, you have a great chance of getting it if you can show it will work, they want people off the live register and we found them very helpful.
