Employee liability insurance

Hi,

I am confused about the requirement in section 142 of guidance. i have to provide two documents from that section right? But the thing is i have just started working as self employed and by the time i apply in march i will only have UTR number. The rest of documents i wont have with me as it will be too early for a tax return and i dont require VAT registration.

I am working as a sole trade and i do not employee any one so i really cannot get employee liability insurance. Is it ok for me to get the public liablity insurance instead? if not then any suggestion what kind of evidence could be used by a newly self employed applying in March?

Thank you very much for your help.

anyone?
