Trying a split otherwise is called artificial seperation, you can out it under a name of someone else, but if they live in same house or are related- or a partner and its same business type you still asking for inspection...
I dont know how the business you are talking about before in the chippy got away with that as i spoke to a tax advisor on my round and he said, one hairdressers was taking staff as self employed and they all filed tax returns to avoid vat between them, anyway, the inland revenue inspected and made them all liable as they had something in common - The Door!! Funny- point being, dont try pull the wool over as you might get a nasty surprise one day when you owe alot of money!! Try go with it, as lee says part of being in business is finding ways to work with these issues, if as a wc you are looking at vat then you are doing well - keep going dont avoid it, legitimately or otherwise!!
I used to want a way round it but some of the more experienced ones on here have built their business past the threshold so it is doable with some thought, and more hard work !!
