Right, thats very interesting, I'm a book keeper so thought I could do a few hours for them and then maybe find other bits of work if I was self employed.
I would be doing regular hours with them though and using their equipment so need to look into this a bit more.
It's just a family business with no employees so they don't want to start with payroll, just need someone to do their books a couple of days a week and would treat me as a supplier really, I don't think there's anything un-toward about it.
Don't know if this throws a different light on it but thanks for your help everyone.
