The number of mortgage accounts affected by the tracker scandal has risen by 3,100 to 13,000 since March, according to the Central Bank.

In an update on its examination of the issue, the regulator said 23 mortgage holders have so far been identified who lost their homes as a result of being improperly moved from their low-rate tracker product to a higher rate loan.

A further 79 buy-to-let customers affected have also had properties repossessed.

The Central Bank said it expects both of these figures to rise.

By the end of September, banks had rectified the interest rates applied to around 7,700 (98%) impacted mortgage accounts that have so far been identified - a rise of about 1,400 since March.

It said €120m has been paid to around 3,300 customers as a result of the examination. 

This is in addition to €36.8m in redress and compensation provided by Permanent TSB and €6.2m by Springboard Mortgages to customers in relation to their Mortgage Redress Programmes, which predate the Central Bank's examination. 

In its update today, the Central Bank said three further lenders are "at an advanced stage in the development of their redress and compensation proposals", and they will commence their programmes "shortly".

It also said that two lenders are undertaking further review work and are to submit additions to earlier reports.

The Central Bank said it is "challenging" these two lenders to ensure that this review work is completed without delay.

It is expected that all lenders will have started providing redress and compensation to customers affected by the issue by the end of the year.

It also said it would continue to provide updates as its phased examination progresses and will publish a comprehensive report when the examination is completed.
