ok, head office rang me back there and apologised. Confirm that I am being moved to 5.19% so confirming the 71bp reduction...
I asked what the criteria was and she informed me that they are standardising the SVR. So LTV>80 and <80% are reducing to the same as the SVR...
obviously >80% will reduce by 71bp, < 80% are on a lower rate so will reduce by less and the SVR will reduce by the ECB reduction of .25%
