3.2 IN-SCOPE MORTGAGE ACCOUNTS 3.2.1 In the course of the Examination the lender is to review all mortgage accounts in respect of both Private Dwelling Houses and Buy-to-Let properties: APPENDIX 1 3 that originated on Tracker Interest Rates1 ; that had Tracker Interest Rates applied at any stage during the term of the underlying mortgage agreements; and/or where the underlying mortgage agreements provided for contractual rights to or options2 for Tracker Interest Rates at any stage during the term of the agreements. For the avoidance of doubt, this includes all mortgage accounts that have been redeemed, sold or transferred to another entity by the lender, together with mortgage accounts where the customer has lost possession of the secured property for any reason (including by way of voluntary and involuntary sale). 3.3 SEGMENTATION 3.3.1 For the purposes of the Examination, the lender is to identify all circumstances where: Tracker Interest Rates were applied to mortgage accounts at any stage during the Relevant Period but are no longer being applied to those accounts; a Tracker Interest Rate margin applying to a mortgage account at any stage during the Relevant Period is higher than any previous margin applied to that mortgage account; customers had contractual rights to have Tracker Interest Rates applied to their mortgage accounts at any stage during the Relevant Period and the Tracker Interest Rates were not applied to their mortgage accounts at the appropriate and/or any stage during the Relevant Period; and customers had contractual rights to be offered the option of having Tracker Interest Rates applied to their mortgage accounts at any stage during the Relevant Period and were not offered the option of having Tracker Interest Rates applied to their accounts at the appropriate and/or any stage during the Relevant Period and to determine whether or not all: contractual rights and obligations regarding Tracker Interest Rates were adhered to and/or honoured during the Relevant Period; and obligations arising pursuant to the consumer protection regulations as set out in the “Regulatory Framework” section below were complied with. 3.4 REGULATORY FRAMEWORK 3.4.1 In the course of the Examination, the lender is to determine whether or not in all circumstances it has complied with its consumer protection regulatory obligations arising pursuant to the following: Code of Practice for Credit Institutions, 2001; Consumer Protection Codes, 2006 and 2012; 1 For the purposes of the Examination, a “Tracker Interest Rate” refers to the interest rate applied to a mortgage product: 1) which tracks a rate which comes from a publicly available source which can be verified by both the customer and the regulated entity, including without limitation, a rate that tracks the European Central Bank (ECB) main refinancing operations rate; and 2) which is calculated in a manner similar to a rate which falls within 1) above, and includes interest rates calculated on the basis of a fixed rate margin and/or pricing promise. 2 Both enduring and one-off contractual rights and options are to be included within the scope of the Examination.
For those of us, like myself, who are unsure whether you have a claim [largely based on never being on a tracker], it looks like there may be hope if you were not offered the option of traker when it was available.
