According to the Central Bank's Statistical Release of 4 June 2015, at the end of March 2015, non-bank entities accounted for 5.1 per cent of all outstanding mortgage loans (6.3 per cent in value terms).
The Release noted that non-bank lenders hold almost 46,000 mortgage accounts for principal dwelling houses (PDH) and buy-to-let (BTL) combined. The Central Bank informed me that it does not release this data by institution or mortgage type for confidentiality reasons and, accordingly, I do not have a breakdown of this number.
However, in relation to loans held by or sold to unregulated entities, I am glad to inform Deputies that borrowers are now protected by the Consumer Protection (Regulation of Credit Servicing Firms) Act 2015 which has just been enacted.
