This case is very important for customers of ptsb and Ulster Bank who incorrectly lost their trackers and later switched lenders, so I contacted Penny who shared the documents with me.
The key point here is that ptsb agreed what is blindingly obvious, but has been refused by them in other cases and what has been refused by Ulster Bank and ICS
“In order to provide full remediation we issued the same mortgage balance and terms and conditions as when they left with the tracker rate of 1.1%”
Full remediation can't be given unless the lender takes back the borrower on the tracker rate.
