I think that the mortgage is still with Danske, but administered by Pepper, but I could be wrong
[broken link removed]
"Danske Bank A/S, trading as Danske Bank (Danske), no longer provides personal banking services in Ireland. However, there are no changes to the terms and conditions of existing private residential mortgages, investment housing loans and personal loans still owed to Danske.
Danske appointed Pepper Ireland to provide the day-to-day administrative services to the customers of these loans from 16 June 2014."
Best is to call them to ask.
