Universal Credit for self employed

Luke1Seaward

I've made my universal credit claim online. But when i try to confirm my identity it says 'we are unable to verify your identity' (due to no credit history). I am a 19 year self employed person. I've been self employed for 8 months and have not been able to fill in a tax return as i have not completed a full years work and the HMRC have indicated that i don't have to fill one in until the next tax year (19/20). In order for my claim to be processed, how do i get passed the verification process as both the post office and digidentity have stated they don't have enough information to verify me. I have a British passport, provisional driving license and a uk bank account.
