Delays to registering for Self Assessment

I set up an LLP in September 2022. My business partner and I are the delegated members and we are required to submit a personal self assessment each in addition to the company Partnership Tax Return. I am waiting on my business partners UTR number. He applied for the self assessment by paper form in early July. We have since sent two chaser letters with the same printed form signed. How long should it take to receive a UTR number? We require it for the business' first Partnership Tax return and am very worried we will face fines for not submitting by the deadline of 30th October because of HMRC's own delays. Please assist.

Hi Carl Harris,
Based on when this was sent we would have expected the UTR to be setup and issued by now.
He will need to contact our Self Assessment helpline so that we can check the progress of the form:
