Apologies, you are absolutely correct, and it was only when I checked the timeline again I realised I was wrong when the poster brought this up in March - it looks like I had commented without asking about drawdown date.
@Nowronganswer the High Value rate for LTVs > 80% only came into being on 23rd January 2021. I understand now that you drew down before then. The rate you were offered was the best rate that was available from PTSB at that time for your cirumstances. I'm sorry for misguiding you on your previous post on this.
Your existing rate (2.95%) equals the best rate they make available for existing customers, so there is no benefit to you breaking & refixing, unless you are able to switch to another lender. However, this won't be possible until 12 months after your first drawdown.
