I am French and have lived in the UK for the past 4 years. I have just left my job and my house to travel in Europe and Australia and have no fixed address in the UK. As a matter of fact, I don't know at this point if I will come back to the UK at all.
I am wondering if I can use any address in the UK (e.g. a friend's) to register as self-employed? Will it cause them any issues?
Thanks for your help!
