Yes you will be mostly asked for a new PCC. My first application was from Dec 2021 which was returned due to missing signatures and when we resubmitted the application in June 2022 , we provided the PCC we got on Oct 2021 and In Sep 2022 post my AOR and medical request ,on the same day i was also sent a request to submit new PCC. I resubmitted the same in October post which my eligibility was moved to in progress.
Its always safe to be prepared to avoid time delays. PCC is not gonna cost you much but a time delay in processing will cost you.
