I'm turned self employed in February, although its really just a bit of a cop out. I don't have a physical office although for legal purposes my house is classed as my companies business premises & I don't have anyone who works for me. I just contract/consult for whichever company has a vacancy for what I do & get a day rate, but no benefits - no holiday or sick pay, pension, medical etc. Hired an accountant who I just pay a fee every month to do my books.

Worth doing, depending on what you do, you can make a lot more as opposed to if you were staff.
